10 Romantic Time Travel Movies to Binge Watch: I’ll Love You to the End of Time

These are some of the best time travel romance movies!

Time travel as a genre is always fascinating in any medium, whether a book, movie, TV show or comic. The possibility of meeting anyone in existence, going to places long forgotten, and uncovering secrets of well-loved icons of the past and maybe even the future gives a special allure to time travel romance movies.

The fantastical direction this genre takes adds elements of magic, naivete, and touches of illusion, appealing to older and younger viewers alike. Add into this the sprinkle of romance, and you have me hooked.

If I get the chance to watch Shakespeare wooing a girl from the 21st century using poems that have become cult classics, I’m grabbing the popcorn and switching my phone off.

Like most people, I grew up watching time travel movies. Consequently, they have become my favorites. For example, we can all appreciate Bill and Ted’s Excellent Adventure or watching Hermione travel back in time to see herself punch Draco in the face. (Not only a win for Harry Potter fans but for girls all around.)

Meanwhile, Doctor Who (2005) is my first exposure to real romance and time travel. With the Doctor’s companions all falling for him, he initially only falls for Rose (Nine and Ten).

As a result, it had millions of us hoping he would appear in our living rooms, ready to take us on our own adventure. Since then, there was no going back. There are just so many romantic time travel movies calling out to be binged.

Here is a list of my personal favorite romantic time travel movies that have thus far survived the test of time. However, I will admit this list is not exhaustive (limiting the films to 10 was difficult).

10 ROMANTIC TIME TRAVEL MOVIES TO BINGE WATCH

(In No Particular Order)

#1: ABOUT TIME (2013)

Without a doubt, this is a humorous and engaging retelling of a classic boy trying to win over a girl story. Tim wishes to change his life and get a girlfriend. With this intention, enter Mary.

Tom falls for her and is relentless and tenacious in his pursuit, all thanks to a family secret. The men in his family can travel through time! What a secret to have, and at 21, your options are endless.

About Time beautifully captures the fun-loving side of romance. And, as viewers, we see the benefits of having such a gift and just how painful the gift can be.

For this reason, we see the love between a man and woman and the close relationship between Tim and his father, played by the talented Bill Nighy . Have tissues ready, as poignant scenes will get you teary-eyed.

Content Note: This film is rated 12A in the UK for mild profanity, nudity, violence, and moderate love scenes. For the same reason, About Time is a mild rated R in the United States.

#2: THE TIME TRAVELER’S WIFE (2009)

This falls quite high on my list of must-watch romance films in general as it has sweeping romance and not to mention swoon-worthy Eric Bana as the protagonist. The film beautifully interweaves through different phases of time, keeping the viewer enthralled.

It follows the life of Clare (Rachel McAdams) and how she meets Henry (Eric Bana), or rather how he encounters her. Clare and Henry ‘meet’ in a library. Soon, they both know what Henry is and what he can do, which is being involuntarily thrown through time, forwards or backward.

The movie’s most interesting aspect is that, despite Henry being the traveler, Clare knows more about him. She’s even aware of their relationship during their ‘first meeting’.

You can assume this is not their first meeting without giving too much away. The story follows them through their life together, how his continued absence becomes a toll on Clare, and over time, it delves into the life of living with a time traveler.

Could you live with someone who knows your future? They will know exactly where your life together could end up. Instead of going for the fated lovers’ angle, this looks at how fate may have brought them together, but should they have walked away?

Content Note: This film is rated 12A in the UK for mild sensuality, nudity, and profanity. In the US, the film is rated PG-13.

#3: SOMEWHERE IN TIME (1980)

If you prefer sweet innocent love stories with classic romance, Somewhere in Time will be perfect for you.

Set in 1972, Christopher Reeve stars as student Richard Collier who travels to Mackinac Island to stay at the Grand Hotel, where he sees a portrait of a woman who he becomes enamored with.

He finds out she was a famous stage actress who has passed away. In this obsession with the picture, he finds a way to go back in time to meet her.

Using methods of self-hypnosis, he is able to get back to 1900 and meet Elise McKenna, but what fate is in store for two people with such a big ‘time’ difference? Get ready to fall in love with the characters, cinematography, music, and love stories all over again.

Fun tidbit: Somewhere in Time was nominated for an Oscar for best costume design.

Content Note : This film is rated PG for mild profanity and sensuality.

#4: THE LAKE HOUSE (2006) AND IL MARE (2002)

The Lake House is a somber story, showing love with a facet of yearning, similar to Somewhere in Time . Both have protagonists who are trapped in different times.

Kate Forrester (Sandra Bullock) moves to a new house, leaving behind a letter for the next tenant. The person who reads the letter, Alex Wyler (Keanu Reeves), realizes some unusual things are happening.

Events mentioned in the letter have yet to occur. They come to the realization that they are exactly two years apart, writing from different times.

This charming movie weaves a beautiful story that will appeal to anyone in a long-distance relationship. You will be able to relate to the dates they attempt to go on and how they try and share experiences with each other.

It will make you appreciate that you are at least a phone call away. The ending of the movie will have you on the edge of your seats, and the revelations revealed will make you want to believe in fate and kismet take your pick.

Special mention to the original movie Il Mare (2002), a Korean production and equally a must-watch if you don’t mind subtitles.

Content Note: This film is rated PG with mild profanity, alcohol, and drugs.

#5: BACK TO THE FUTURE PART III (1990)

If you are not familiar with this series, what are you doing? Marty McFly (Michael J. Fox) and the iconic DeLorean made a generation of kids dream about hoverboards and Nike trainers.

This is the third installment of the series, giving more focus to the ‘Doc’ Emmett Brown (Christopher Lloyd).

Set against the backdrop of the 1885 old west (and true to the name), we get standoffs, brawls, and romance. Meanwhile, Marty travels to 1885 and is stuck because his car breaks down.

Of course, he has a run-in with ‘Mad Dog’ Biff Tannen and his unruly gang. (Trying to send Marty back with their limited resources makes you appreciate a lot of amenities we take for granted.)

In this process, Emmett meets a school teacher, Clara Clayton (Mary Steenburgen), who is a science geek just like him, and soon a romance blossoms.

It is surreal and sweet to see Doc so enamored and unable to figure out how to act. Furthermore, the romance breathes new life into his character and shows an angle we never thought we needed.

In the climax of the movie, there is a race against time to get the DeLorean fixed and Marty back to the present day. Ultimately, even as a sequel, Back to the Future Part III is brilliant.

Content Note: This film is rated PG with moderate profanity, mild sensuality, nudity, and violence.

#6: MIDNIGHT IN PARIS (2011)

‘ You’re in love with a fantasy.’ ‘I’m in love with you.’

Woody Allen does it again, giving us a spellbinding movie with sophisticated and witty characters. He portrays Paris in a way that will make you want to go there and explore.

Winner of an Oscar, Midnight in Paris follows Gil (Owen Wilson) and Inez (Rachel McAdams) on vacation in Paris, where he wishes to move after they marry.

However, his wife-to-be doesn’t see the magic of the city, hoping to settle in America instead. In the meantime, Gil struggles to write his first novel and takes a strange late-night stroll through Paris, getting an invite to a party that includes guests such as Fitzgerald, Hemingway, Gertrude, and many others who frequented the famous salon of Stein.

It is up to the audience to decide if this is time travel or just the fantasy of a desperate writer who is in love with the golden era of the ’20s. I thoroughly enjoyed this movie because it gave a glimpse of how some of my favorite writers would interact.

This is what other genres cannot do, transport and introduce characters and figures who we would love to meet. This charming film will have you falling in love with the characters and the dialogue.

The superb acting by Wilson portrays an awe-struck, enthusiastic writer who meets his heroes. There is no real story to follow, but rather more events that unfold and how the characters react to them. But life is like this sometimes: we don’t know where things are going until later on.

Content Note: This film is rated 12A  in the UK and PG-13 in the U.S. for mild profanity, sensuality, and nudity.

#7: 13 GOING ON 30 (2004)

13 Going on 30 is a reverse-coming-of-age time travel romantic comedy. Jenna (Jennifer Garner) makes a wish on her thirteenth birthday, wanting to be older after going through an embarrassing ordeal.

Jenna wishes to make her older, and it is fulfilled magically. She wakes up the next day to find she is weeks from her thirtieth birthday, has a dream job as a magazine editor, a car, and a very attractive boyfriend.

Everything that anyone could want, but she is still not happy, which pushes the story toward what she truly desires.

This approach is always fun to watch, including hilarious scenes where the protagonist tries to understand the new circumstances and her new body. I admit it’s nothing new in terms of what we can expect, but Garner portrays the character’s innocence and naivete so well.

We see beautiful shots of New York City, which will make you want to book your flight and get over there. However, the surprise in this movie is Mark Ruffalo, who plays Matt, the high school best friend.

Seeing him in this role will be new and a fresh take for fans of the Marvel world. One of the best moments in the movie is the Michael Jackson ‘Thriller’ dance which will leave you astounded and get you on your feet.

Content Note: This film is rated 12A in the UK and PG-13 in the U.S. for mild profanity and suggestive content.

#8: WINTER’S TALE (2014)

Winter’s Tale is set in 1895 on the streets of New York and is based on the novel of the same name. Peter Lake (Colin Farrell) is a seasoned thief who enters the home of Beverly Penn (Jessica Brown Findlay). Beverly catches him in the act.

They both fall in love, and she tells Peter a story about how everyone is born with a miracle inside them. This is the theme for the whole movie so keep this in mind while watching.

The movie boasts a lot of big stars: Russell Crowe, Will Smith, and William Hurt, who all play fantastical characters brilliantly. The story jumps to modern times showing us Peter again. But he has amnesia, setting the story for the rest of the movie. The search for his memories and lost story.

Romance like this is always beautiful to watch, even though the audience and characters know it will not be the happy ending we all hope for.

Fans of Downton Abbey will recognize Findlay as Lady Sybil Crawley, carrying off the character of Beverly competently, with a timeless beauty that is only enhanced because we know the fate of the character.

Farrell is exquisite as always, playing his role as an Irish thief so convincingly. There are many twists and turns to keep you entertained during the second half, which is worth the effort.

Content Note: This film is rated 12A in the UK and PG-13 in the U.S. for violence and sensuality.

#9: IF ONLY (2004)

If Only uses the winning formula that led Groundhog Day (1993) to success, where the day is on repeat. We have Samantha (Jennifer Love Hewitt) and Ian (Paul Nichols), who are a typical couple, showing the relationship and fights.

Tragedy strikes when Samantha has a car accident leaving a heartbroken and grief-stricken Ian. But fate gives him another chance to back in time to try and change events. He lives the same day again and, like any sensible hero, tries to alter the events leading up to her accident.

It’s a sweet story showing the importance of cherishing the people close to you. The film further makes you wonder about how you would react in this situation. Would you be able to change anything?

The story moves at a good pace, keeping audiences on edge as to whether Ian will succeed. Very beautiful moments occur between the two as Ian knows what will come.

He tries his hardest to make everything perfect (and take notes, guys – ahem, ahem). Tissues may be needed; you have been warned.

Content Note: This film is rated PG-13 for some sensual material.

#10: KATE & LEOPOLD (2001)

‘I’m not very good with men.’ ‘ Perhaps you haven’t found the right one.’

This time travel romance movie captures everyone’s heart because Leopold (Hugh Jackman) comes from 1876 and has a romantic, classic approach to love.

He has purity dripping from every glance and every word he speaks. It would make any girl fall head over heels for the chivalrous Leopold.

So, what chance does Kate (Meg Ryan) have? Leopold needs to marry someone for wealth, with a dwindling purse and big dreams to pursue. He enters a portal transporting him to modern times. This blows him away to see the sights and progress.

He meets Kate, a market researcher who is cynical but ambitious. They get close but inevitable differences arise, and he returns back to his time.

Kate & Leopold also provides well-written comedic scenes with Kate’s brother, an actor assuming Leopold is deep in character. For fans of epic romantic movies from the ’90s, this 2001 film is equally awesome. Plus, any fan of Jackman will enjoy seeing him in this swoony role.

Content Note: Rated PG-13 for brief strong language.

Did you find one of your favorite movies about time travel and love? If you had the chance to have one of these romances, which one would it be?

Found some new ones for my list, so thanks! I love Hugh Jackson in Kate and Leopold – he plays it so straight it makes the whole thing so much funnier.

Though I haven’t seen it in a while now, I remember that I liked “Lake House,” and I just started to watch “About Time” last night. It’s nothing like I expected, but so far I quite like it! 🙂

Man, Rachel McAdams is all about that time travel life!

Oh, I hoped I’d find a new romantic time travel movie to add to my watched list, but I’m afraid I’ve already seen them all. Lovely curated list, tho!

A long time ago there lived a scientist who would hardly ever venture outside. His life was a lonely one, with long days of research and experiments. It was his ambition to create a potion to see into the future. He had over years collected hundreds of herbs and combined them in various ways until eventually, he was on the brink of a breakthrough…

Where am I able to find the remainder of this story? One mustn’t dangle a carrot expecting no one to bite! Rachel

All these are lovely —- another good one is “1994 Timecop” with Jean-Claude Van Damme and Mia Sara — thriller & romance

I can’t seem to find the movie which was based on a short story “ Christopher Frame “ a photo restorer who time travels ,.falls in love and stays there , tried to lookup but there is no information about it ,I can’t remember the name of the movie or episode either for the love of God ,If anyone knows about it please let me know ,thanks

Another outstanding time travel movie is the 1998 Hallmark Hall of Fame production “The Love Letter”, starring Campbell Scott and Jennifer Jason Leigh. Aired in the late 90s, it’s about an engaged civil war buff who finds hidden letters in an old desk which were written by an unmarried woman in 1863. He is compelled to respond to her and even though he lives in the late 20th century she receives his letters and they begin a correspondence through time. This obviously causes a big problem for his life with his fiance. It’s an excellent movie based on a short story by Jack Finney. Finney is the author of two great time travel novels, Time And Again and From Time to Time.

Hi Everybody, I read through the candidates for best time travel romance, all of which I have seen. I agree with your choices, but not exactly in that order. Although they were all great movies, it is “Somewhere in Time” that takes the number one spot. I was happy to see that at least you gave them the 3rd spot, but, in reality, it was the one movie that expressed so beautifully the concept that love transcends time and in the end, true love brings them together as they slip off into eternity.

There is one more movie to which I would give honorable mention. That is the 1979 movie “Time After Time” where the prolific writer HG Wells pursues Jack the Ripper into the future where Hubert (Malcolm Mcdowell) meets Mary Steenburgen and falls in love. This is another great movie. Thanks, DAD

Hi Dad! I agree with you that Somewhere in Time is the best time-travel romance movie. 🙂 Such a beautiful film!

Time travel is possible, but it’s a one-way ticket

Chenoa van den Boogaard , Physics and Astronomy editor

The ability to travel through time, whether it is to fix a mistake in the past or gain insight into the future, has long been embraced by science fiction and debated by theoretical physicists. While the debate continues over whether travelling into the past is possible, physicists have determined that travelling to the future most certainly is. And you don’t need a wormhole or a DeLorean to do it.

Real-life time travel occurs through time dilation, a property of Einstein’s special relativity . Einstein was the first to realize that time is not constant, as previously believed, but instead slows down as you move faster through space.

As part of his theory, Einstein re-envisioned space itself. He coined the phrase “spacetime,” fusing the three dimensions of space and one dimension of time into a single term. Instead of treating space as a flat and rigid place that holds all the objects in the universe, Einstein thought of it as curved and malleable, able to form gravitational dips around masses that pull other objects in, just as a bowling ball placed in the centre of a trampoline would cause any smaller object placed on the trampoline to slide towards the centre.

The closer an object gets to the centre of the dip, the faster it accelerates. The centre of the Earth’s gravitational dip is located at the Earth’s core, where gravitational acceleration is strongest. According to Einstein’s theory, because time moves more slowly as you move faster through space, the closer an object is to the centre of the Earth, the slower time moves for that object.

This effect can be seen in GPS satellites, which orbit 20,200 kilometres above the Earth’s surface. These satellites have highly precise clocks onboard that gain an average of 38 microseconds per day due to time dilation. While this time gain seems insignificant, GPS satellites rely on their onboard clocks to maintain precise global positioning. Running 38 microseconds fast would result in a positioning error of nearly 10 kilometres, an error that would increase daily if the time difference were not constantly corrected.

A more dramatic example of time dilation can be seen in the movie Interstellar when Matthew McConaughey and his crew land on a planet with an extreme gravitational field caused by a nearby black hole. Because of the black hole’s intense gravitational influence, time slows dramatically for the crew on the planet, making one hour on the surface equal to seven years on Earth. This is why, when the crew returns to Earth, Matthew McConaughey’s daughter is an old woman while he appears to be the same age as when he left.

So why hasn’t humanity succeeded in making such drastic leaps forward in time? The answer to this question comes down to velocity. In order for humanity to send a traveller years into the future, we would either have to take advantage of the intense gravitational acceleration caused by black holes or send the traveller rocketing into space at close to the speed of light (about 1 billion km/h). With our current technology , jumping a few microseconds into the future is all humans can manage.

But if technology one day allows us to send a human into the future by travelling close to the speed of light, would there be any way for the traveller to use time dilation to return to the past and report her findings? “Interstellar travel reaching close to the speed of light might be possible,” says Dr. Jaymie Matthews , professor of astrophysics at the University of British Columbia, “[but] this voyage is one way into the future, not back to the past.”

If we can’t use time dilation to return to the past, does this mean that the past is forever inaccessible? Perhaps not. Einstein proposed that time travel into the past could be achieved through an Einstein-Rosen bridge, a type of wormhole. Wormholes are theoretical areas of spacetime that are warped in a way that connects two distant points in space.

A visualization of a wormhole: The fabric of spacetime curves back upon itself, forming a bridge between two distant locations. Image by Panzi , CC-BY 3.0

Einstein’s equations suggested that this bridge in space could hypothetically connect two points in time instead if it were stable enough. “At the moment, even an Einstein-Rosen bridge cannot [be used to] go back in the past because it doesn’t live long enough – it is not stable,” Matthews explains.

“Even if it was stable, it [requires] other physics, which we don’t have. Hypothetical particles and states of matter that have “exotic” physical properties that would violate known laws of physics, such as a particle having a negative mass. That is why “wormholes” are only science fiction.”

While it would be fascinating to travel back in time to see the dinosaurs or to meet Albert Einstein and show him the reality of time travel, perhaps it is best if the past remains untouched. Travelling to the past invites the possibility of making an alteration that could destroy the future. For example, in Back to the Future , Marty McFly travels to the past and inadvertently prevents his parents from meeting each other, nearly preventing his own existence. But if he had undone his own existence, how could he have travelled back in time in the first place?

Marty’s adventures are a variation of the grandfather paradox: what happens if you go back in time and kill your grandfather before your father is conceived? If you are successful, how is it possible that you’re alive to kill your grandfather in the first place?

A recent study at the University of Queensland may have the answer to this baffling paradox. In this study, the researchers prove mathematically that paradox-free time travel is possible, showing that the universe will self-correct to avoid inconsistencies. If this is true, then even if we could travel back in time, we would never be able to alter events to create a different future.

While these new findings are enlightening, there appears to be more evidence that, although time dilation can allow us to glimpse the future, we will never be able to visit the past. As the late Stephen Hawking said in his book Black Holes and Baby Universes , “The best evidence we have that time travel [into the past] is not possible, and never will be, is that we have not been invaded by hordes of tourists from the future.”

How do I go about time travel? what do I need how do I get those required things?

Very large ring magnets and some mathematics and will to see it in reality.

How about a sphere magnet ship…

hoe about 3d time and hemi synch or portals augmented reality,power of suggestion..drugs pcp binural tones frequency amplitude .virtual computing ie.

I’m a time traveling tourist, Stephen Hawking was wrong.

Time is simply a measurement of space under the amount given its mass and the amount of light and dark in which governs its mass in a 4dimensional reality step outside of the force in which permenates its flow one would reside there would be no past present or future there be a fixed permance of a constant here and now and so ok then what is to come.

Very well explained article !!

But I think if physics says time travel can be possible then it’s definitely possible. Considering not to go back to your childhood and fix things but rather can go to the past but as invisible person to them. So that,

No actions by you would impact your future.

Regards, Kirankumar DR

Tell me more

Yes.. I wish I can do this too 🙂

We will understand it better, by and by…

I have a theory for warp speed, but nasa would have to put it to the test…check my Facebook

I am reading for this drive , i am ready , without think my life safe or not

@Ravi chandila English translation please?

Please someone help me I just want to send a message to myself in my past.,to get the love of my life, he never revealed to me his feelings now my life is ruined by the decision of my elders Please help me, it’s question of my life and death. Nazneen

Is time travel machine is their, if the time travel machine is true can it move to the past . To bring back my lost life

That’s the problem you know.. it is not there that’s why we aren’t able to travel time..and yes it it will be built then you will be able to do so…..

damn my life is also lost and broken but still no one can give a time machine for free

DO NOT change the future. That’s why people like you couldn’t go. One wrong person to ruin it for the rest of us

On the point of time reversal, it is evidently impossible. The Uncertainty Principle prohibits spacetime reversal. The Universe is unable to remember its past (as a consequence of the Uncertainty Principle), therefore the Universe cannot reorganise itself.

Can I have to go on my past with another time travel it is a possible when just tell me about one thing that can I have to go in my past one year

we dont need magnets.we need a strong gravitational force to warp spacetime allowing us to travel through with speed of sound or speed of light or faster.we need to learn how to control such force carefully or it could be lethal.gravity slows down time.but it can theoratically work both ways.if we can reverse the gravity’s natural reaction we could speed up a spacecraft faster than light(its all relative(and theoratical))

I WAS ACTUALLY JUST THINKING THE SAME THINFG BEFORE READING YOUR PIECE. VERY WELL EXPLAINED, AND IT DOES MAKE ALOT OF SENSE. WELL DONE.

oh and I forgot to add it can be the key to look into the universe and also travelling time(theoratical).speed and gravity are the key to the universe(theory not proved)

All you really need is a crystal diode with 16 sides, a large pain of glass, and a frequency transmitter near a bathtub full of ice cold water….if you reach the right frequency you can travel through time forward and reverse…

Magnetized metal(VCR Reading Head), to read time out of the Magnetosphere all around earth. The Magnetosphere kills 2 birds with one stone- it protects earth and it records human time:

Mystery solved and I will explain, I was in a coma 3 months and I experienced things, I traveled time forward and backward, it is not a one way ticket. Movies and songs are recorded on magnetic tape in a VCR tape Cartridge or Cassette tape,   Magnetic tape recording works by converting electrical signals into magnetic energy, which imprints a record of the signal onto a moving tape covered in magnetic particles.   3D life on earth(a movie), and the Magnetosphere all around earth coming from the core of earth(MAGNETIC ACTIVITY) without Atom Made Tape, is like a movie on magnetic Atom made tape in a VCR tape cartridge. Revolution and Rotation is the motor(VCR).

This is why people have those freaky Deji’vu feelings like they have lived this before, BECAUSE YOU HAVE, and how people can be psychic, and how there is Prophecy in the Bible. When a person dies, their Spirit- MIND(Thoughts, Feelings, Urges(Physical and mental personality)) breaks out of human body- a stopped heart is what releases the spirit from the human body. Then the Soul(Life) with the memory of your existence in it breaks out of spirit and goes back to your birthday with a erased memory, meanwhile your spirit goes back in time to when you were a teenager starting the mental puberty, maturity from that adult spirit you died with in last life.In that old movie Star Wars or maybe it was the Empire Strikes Back, there is a scene where Princess Laya plays like a 3D movie, that is EXACTLY how its of life on earth.

Mr Snow, I believe you as I have seen it too. As humans we have deep knowledge of things we cannot rationally explain but you have done a great job here.

I thought that Analogy would be a better and easier way to explain, or in a picture of the earth from far out in space with the atmosphere around it looks like a DVD disk and the earth being the center sticker but is in 3D.

Actually you are on to several things here. I have also had the infusion of knowledge that also had to do with comparing life to recorded movies and music. I know you were using it to explain your theory, but I do think there is something there, I always have. When you watch a movie you are seeing the past. Why can’t you somehow use a recording as a base to go back into? I agree with everything you said here, and it’s worth looking into.

Jeffrey, very interesting idea!! Could be something to that. As far as your coma experiences, I think there are things we just do not understand and are nearly impossible to explain. Perhaps time IS like a video tape, or a DVD? Magnetism is one of the forces of nature. I too have had some odd experiences that suggest that we are able to perceive things beyond our five known senses.

I think if you have had a near death experience, such as being in a coma, then you have experienced the powerful hallucinations provided by the chemical substance DMT which your body creates naturally in times of extreme trauma, but also found in most plants and used recreationally by some who are brave enough and into that kind of thing. Your theory is interesting, but completely unproven and as far as I know untested. If things were so simple, I’m sure many scientists would have already thought of such an idea and tested it.

How do I travel through time

Be alive and live life to the fullest is the best way to travel through time ! OR Befriend grey aliens../ They may hold the key to the sum of all knowledge in the universe..

Sounds good will it work

Really log vaps mil sakte hau h kya

Can you plz explain I didn’t get it

You dont first all you are not experienced in the field of the space time continum and you could you upset the already fragile and multitude of alternate realitys that have looping due irresponsible ones who somehow gotten the technology causing another altered time frame there are a disarray multiple reality which are looping in earths 4dimensonal time frame time traveling is not for a vacation or just to get a joy ride its a serious and complex reality not be joked about it is a real thing and certain individual have are upset the balance of earths original time zone note now the gaurdians of this region of milky way the galatic order of the light keepers Angelic gaurdians of the (names with held)are working over time ooh nice pun (over TIME) ha wow to restore Earth back to a original time continum

Who said I want a joy ride, my life is devastated even my kids are suffering, I want to commit suicide but can’t leave my kids back, Being captive for most of my life, if my life is changed nothing will be disturbed, only thing happens is 3 life’s will be saved. And more so over I don’t want to travel I just want to send a message to myself in my past plz on the date of 30th May 1996. My life is ruined plz help me, it was my dad,brother, sister who pushed me into the dungeon and my husband and his family took over the charge of torturing me. Nazneen

I want to go back in time and tell my 5 year old self to burn the creepy dolls that my mom bought cause there is demons in it at the same time I will kidnap and torture my dad right now go back in time and show the younger version of my dad show him what will happen to his future self if he don’t get rid of those possessed objects and keeps letting my mom buy those antiques I’m 18 now I’m single no girlfriend no friend alone nothing very depressed too and I try to remember the positive things that happened in my life which there aren’t many tho but the demons keep squeezing my memory brain and my mom keeps on making so much loud noise including her damn mouth I have attempted to burn the demonic dolls but I only burned them for a minute or two with gas cause I was worried I might accidentally set my whole neighborhood on fire but then my mom threw it all in the recycle instead of the trash so the demons just keep bothering me its driving me nuts he he.

Access to a Quantum Computer Network on the web would be a good start. A series of ChatBots and webhook sites strategically placed in not only space, but in time. A series of algorithms and I think information can be transferred backwards to ones self…

How do we know that there are no horde of tourists among ourselves?

How do we know we’re all not tourists?

We’re all time travelers. We all travel into the future daily. 1 second at a time. Lol…

Agreed! I had the same thought!

Excellent question

If is possible, I would like to go back to: January the 1st 1975 & relive the 70’s as I prefer that decade to the awful one I am facing now, Back then We had more police our streets & left our front doors open, Those days were far much more better .

Please do comment on my blog post regarding time travel

how about you ask the flash to help you

I need the time travel so I’m fails so many times i love time travel i have to go fast and future so i have no idea im travel is a my dream so my dream solution plz say me i have time travel so please help me someone please…..

I think you are over reacting

When we look at the stars now it is what they looked like years ago so what if we go to the stars and look down?

You cant go to the stars. It will just take billions and billions of years to go even to the next nearest star than our Sun- proxima centuri. Sorry to say, but do you think that you will be alive all those years??

You can do that without going to the stars… our planet reflects light as well thus making it visible from other parts of the universe…. has the word “reflection” crossed your mind ? 😉

Contact me on my hangout I will help you [email protected]

bro just time travel its not that hard

Please help me to time travel, can I see myself when I go back in time like Harmaini sees herself in Harry potter?? Or can I send messages to myself I know the particular date when to send. It’s not the mistake I had done in my past but it was done by my father and brother who are safe, happy enjoying their lives,my life is totally ruined Please help me. Nazneen

I want to go back in time to save my wife .it was a bad mastake she died .that could be changed i need to go back and save her. Please help me.yours gordon sutcliffe

Would love to hear more how it’s possible, as I am really so desperate to go back in time. I lost my wife 6mons back because of COVID and I will do the impossible things to make it happen.

DMT Experience

what is that?

Dmt experience. Time travel, out of body and sometimes superhuman capabilities.

Jump into a black hole

We have to lose something(the past) to gain something(the future) in time travel.Time cannot be played with.Am I correct.

you need to have d e t e r m i n a t i o n

Time machine is possible

speeder than light LOL

speeder than light cuz if the light break it limits it will move backward in time

Don’t Just don’t disturb the past

I want to go back in time and see my dad. I miss him.

mee too raina I lost my father the day before you posted the comment 18th may, crap it hurts me so much. I would rather die to bring those moments back….

Everything is connected . Time isn’t real .

It is universe we travel to and not a time line in one universe

Ask trump….Mandela effect…. dmt 5th dimension

u need an X-WING starfighter and a lightsaber to fight the knights at past and a R2-B2 to track

The fact that no one has time travelled to the past is the proof that time travelling will NEVER exist.

Others have. Portals open most of the time. Example: Miami Fl. Magnetic Material gets bombarded by the sun. Which fractures and formed portals within that area. Ley lines can lead to the portals of travel within miami for just to start. One can laugh or wonder if. In my experience jumping for the better the word of it (Movie Jumper) can be done. You can either Teleport or Time Travel. Our sun open these portals everyday. The best time when Sun spots start to emerge. All that electrons traveling at light speed is enough to rupture our magnetic fields on Earth. You will return of course. Like water on a lake or an ocean time will corrects itself. Your inner clock is your ticket back home. With a little math,fourth dimensional thinking,a magnetic meter, the right location,history research and luck. You may get to expirence it. First clue….cold spots…it may not be a ghost.

Plz can you help me please help me you can save my life

I wish I could help you, I can sense your sufferings.

You need a bag of hyperlink modules to start, then nuclear beepbeep gatangas, when you have that come back here and I will tell you what you need next.

You need high voltage beepbeep gatangas and a large broonasic magnet of about 450 Gauss, come back here when you have these and I will tell you the rest.

you need an old fashioned police box

If you rotate the center of the earth in the opposite direction, then the whole earth can be moved back in time, on the other hand, if you move the center of the earth and change its position by separating it from the part of the earth, then you will be able to time correctly. Let’s reach the other side.

How I could time travel any time travel machines inverted

give audition in the flash series..

I think that to go back in time you’d to travel faster than the speed of light since time stops at the speed of light but if you wanted to go back to say mlk’s assassination you would need to go at least 10 times the speed of light

You don’t want to, the moment you wrote that message is a historical point in time.

It’s Close I can feel it

Yes it becomes a history but my life also in the past changes and the present also with it. The way I’m suffering from the pain and want to end my life I’m 100% sure at least sure no one around me is or was as hopeless and horrible as my hubby I’m devastated I really want to send a message to my past it may not start but it will definitely change. I was forced, not given any option, my father and brother gave me wrong information and had no concerns for me. It was just survival for me. I repent for not killing myself when I had time, but now if I have a chance why not. Now when I’m out of my marriage I come to know a guy then had feelings for me, was madly in love and wanted to ask for my hand, now I want to inform my self and change everything plz help me.

I too would like to go back in time. I just wish he lived a happy eternal life. I would just like to repeat to come back in 2020.

I heard from a guy in Idaho that time travel is possible. You’ll need to go online and purchase a pogo stick looking device and make sure not to forget the crystals.

I think u need a black-hole-proof spaceship, go to the centre, escape the black hole and viola! You are now in the past. If you can’t escape, then you’d travel to a time where that black hole didn’t exist.

Believe me you time travel! If not physically then you do mentally,like you through dreams.

Though they sale it online, it would not take the chance. It is as simple as beating the speed of light and having some system to send you to the time you want. Time however is not real, and were just traving universes. It will all be in the open in 2028 according to other travelers.

All you need base on how to travel to time is very simple but had to find firstly find a way to get to space through a space rocket secondly find a very perfect consifigration for traveling to tiTme then find a very fast rocket that could create a form of force reaction in space in order yo enable fast speed in space for the break through of non gravity in space and make sure that while doing all you activities is not far away from planet and not also to close to planet earth and make sure that you are with wristwatchs whose time is set disame then you can to the future

Man you can get all you need for too build a time machine in your local store man, man I sure wished I’d kept mine but it frightened the heck off me man, sometimes when I fart I find a grape in my pants

time travel is a fake, baseless and delusional idea. If you believe in that crap then tell us if we are living in the future or in the past. To travel backward the entire system has to return all along with nature and events, it won’t be for you alone except time travel only happens in the mind.

you would need to get about 1,000,000 pounds of silicon and then somehow conduct enough energy to make 500 cars run without an engine and then go to a nuqular power plant and somehow make a portal. but the whole world could go out of orbit if you do that so I wouldent sugest it.

Time machine is good and bad because,with the time machine you will know about your future which is not good.

Is time travel actually a real thing because if it is then I need it because I am trying to go back in time to fix all of my mistakes

So what if time travel is the reason that we now believe there are other realities in our own world.this could be that a Time traveler we could only go back and couldn’t come back, and on doing so if you do something to change the past in stead make a new reality.making other things are deferent and ours realty stays the same . sometimes reality gets mixed up make the mandela effect that we see today

Time in the future it is faster then now. The past is slower so you can travel . It is up to you. One way is to meditate. You can travel and see any body you want right now. You can fly faster then light. That is one way. You go to the future. To go to the past you sleep for a long time. Some time you go to the future or the past. Your heart well stop and your body gets cold. Sometimes you can control it sometimes you can’t.

but how do we know that is really true ? i mean i want to figure this out, i want to time travel, but how is it that simple ? so many people have been trying to figure this out for many years and its that simple ?

Yeah what if you get stuck in there what do you do than

You cant go there in the first place. Dont worry. With current technology, we will only end up messing some few microseconds. Highly doubtful, if we can end up getting the news of travelling hundreds of years in our lifetime.

wait what would happen if someone saw you while you where in past/future i’m curious

Time is an illusion based on perceived reality and is only relative to our limitations. Time isn’t what it seems and all things can’t be figured out

Im on a school computer looking this up and i found this article and scrolling trough it and ive not heard one statement here as good as yours bro

This is blowing my mind people, then I see the school boy on the post. Great stuff, whoever reads this is already capable of travelling through time. Think about all people who have posted on this thread, now think about who will read mine. Now think of those €opposite trolls $ who never ever bother posting on you tube thread etc. But ONE comment from one of the time travellers who wrote on this thread. So that opposite troll is me,I don’t normally post.however because of previous comments I’m posting here. And I love the DMT shit I loved that and lived that one out in real life,,,,another day.

So my point is ifOne or two threads have made me write this….then what will my post make others write , think…..then I could travel back and not write this…. then what. Love the conception of time how can u travel something that doesn’t YOU perceive to be time, like a train can only run on its train tracks, a car can only drive on a road etc It’s posibble I know it is. Sometimes when u have fun times moves swift but locked in jail it goes snail pace. U c me. I write letters to myself from past from future. Remember everything that happens in present becomes part the past. But the future is what you hold in your hands. Question is, now you know….what the f are u gonna do about it?.. 01/04 ==== 21

Hahahah only realised school boy is named BIG dick pissing myself laughing I gotta go pee. Respect certified

so not halal mode

True so were not traveling in time. It is just different universe (on what we call) different time, day, tears, etc.

You would be scared for life

you will desepear

Maybe it has happened before and we just don’t know that they’re from the future. If people in the future time traveled, the would know that it’s dangerous to mess with the past and would pretend to be part of the past.

I believe time travel is already possible, however we cannot fix past mistakes without altering future predicaments. Say we stop JFK’s assasination, that would completely change the future from that point forward to one none of us can know/guess or conclude the effects? Other time travel purposes go to the future I think that from now our world will die off before 2096 basdd on overpopulation, global warming & polution as such creating islands of plastic waste in our oceans. The best thing my opinion go back to the garden of Eden, kill that Serpent Satan before he tricks Eve into the forbidden fruit. Then let God raise, enlighten & teach us how to be humanly sustainable on his planet & I guarantee technology & smart phones? Ain’t no part of it!!

Time travel possible but one n only theory of Stephen hawking

How it is possible to jump in time …??

Many ways. The most used is creating a black hole which can be done in a few ways. 1) traveling forwards or backwords faster than the speed of light 2) been known during heavy lightning strikes. Each way is a fast movement that opens the black hole. It has been done by the Government since the 1980s though they claimed they never beet the speed of light until 2002. However, Time is a illusion and their for we are actually traveling different universe that are differnt than ours even if the difference is by 1 thing. Each universe may have (what we call) different time, days and years. And each time we change that time line we created a new one. It is belief as CERN has said they destroy 5 universe, that they can travel to them. Since 2012 it has seem we been shifting and is now belief they have possibly came together. The event is known as The Mandela Effect.

No one has the right theory in my thinking. Only a few things are wrong. It is universes with (what we call) different time, days and years we are traveling to and not time itself as it is a illusion. Their is no stop to how much we can do, or where we can go. No limit as such say.

There is no God. No magical serpent or Garden of Eden ever existed. Basing a scientific theory on archaic stories does no one any good.

You choose a hopeless eternity. I choose hope through the promise of salvation through Christ for those who believe. You see, I have child in heaven. Thankfully, have a hopeful reality that I can embrace. There is a God. Our known universe is only 14 or so billion years old… is it mathematically possible that random molecules out of the Big Bang mixed in just the right way from to form a complex cellular organism… with DNA… and result in humans and such diversity of life forms? It’s naive to accept this as a result of chance. Think about it. How is that remotely possible without a creator?

Hahaha. You make it seem as tho the big bang happened, and we just popped into existence? Naw it’s called evolution baby, we started out as microscopic organisms, seriously, when did you drop out of school? But that’s like saying a some guy writes a book to explain away natural phenomenons that they were to stupid (un-evolved) to grasp and the concept good and bad and the eternal damnation, And thus, the Bible, and boom, everyone now was made by God, hahaha. When you can prove he/she exists, and that the Bible was a autobiography, and not just some twisted piece of Fiction, that has no real basis in reality, and cannot be proved to be more that a work of Fiction. Rather than being used as the16th Century control tact, ‘be good or you’ll go to hell’. But I guess that’s what they mean when they say ignorance is bliss, (maybe if I was as ignorant as y’all believers I’d believe to). But I can’t see how a ‘GOD’ would ever ask one of its creations to kill another.. Genocide, Crusades, all the ethnic cleansing.. All In the name of God Almighty! Hahahahahhaaa. Aliens are more believable than this shit, and theirs no proof they exist either. Hahahahaha. Fug’n Bible thumpers. ‘Step out side your faith and see the world for what it really is, a complex organism, mad of gravity and dust, quite a unique specimen! And we, yes Bible bangers, this includes you, are destroying it like the bubonic plague.’. ‘The end is coming and it’s our fault’

Have you taken the time to read The Old Testament and the prophecies therein that came to be ?.

How do you explain that ?.

My last post should read GS not G

You have not had an encounter yet with God. Don’t be so certain on yuour theory of evolution. He came and shook my reality to it’s core. Made thing possibly that no one could ever explain.

What are you talking about? Ur so wrong and funny in every way.

BlissfullyInformed just told me his comment was all an April fools prank. He believes in Jesus and was just fooling.

Time travel is very much possible just as you decided to come existence in this century meaning one can decide to be in another time zone . life is all about numbers, you just have to work on numbers

I’m pretty sure ppl don’t decide to come into existence. If that were true I wouldn’t be replying to your comment.

Un like your other reply, I understand what you mean. Each timeline (or universe as some see it) can easily be traveled to at will. No different than traveling threw your time you want to visit.

Science has proven a few things from the Bible is true. God does exist. Christians are confused with time and what it says. For a example. God created the world, as science even belives it was God who created the big bang, yet the bang has happen itself creating the moon, planets and stars. Christians also fail to understand chapter 1 and 2 of gen. spoke of two different creations which can be why we see dinosaurs before humans as chapter 1 spoke of animals first and humans 2nd. Their also was different time than, as without the moon a full day is 6 hours. It would take 4 days back than to equal are 1 day. Time is lost and Christians are just confuse on that time. That does not proof their is no God. As they have already found the robes of Jesus and remains of Noah’s ark, it proves much did happen. The bible only has less than 50% of what was written.

Changing the past is impossible, because if we went back into the past, that means we were already there during the time you experienced it.

We all know how to get into time travel but how do we get out……..

You don’t need time travel – all you need is life. And what is life? Life is the evolution of the impossible into the inevitable over an infinite amount of time.

if it is shown that if something, such as a solution to a particular class of equations, were possible, then two mutually contradictory things would be true, such as a number being both even and odd. The contradiction implies that the original premise is impossible.

This is called proof by impossibility. Thus if some traveled back in time far enough to kill his grandfather, we have the contradiction and therefore it is impossible.

You could argue that he would be able to time travel, but not kill his grandfather. However almost anything a person does going back in time would cause the same contradiction, thererfore it is the traveling back in time that is impossible.

Actually, it probably is possible to travel back in time, however to do so, you would also have to travel so far in space that you cannot see anything that happened before your current time due to the speed of light, because this to could affect the future.

The reason I am here is that, i really want to go back the day when our matriculation exam was just finished. Everything around me is peaceful and happy. Currently, I am living in dire situation. People are dying outside on the streets. Smokes everywhere. Everything is in doom. Ah, yeah. I really miss my past. If you are reading this, you can judge me in anyways. I just want to live peacefully and happily.

You must live in Portland

I entirely know what you say and how you feel, Robin. I am totally convinced that future is no promise to offer a better place to live. World is becoming unnecessarily more complex and more horrible and more insecure. Therefore, travelling back in time to a point where things were still far away from such ordeals is what I aspire. But I think if it is possible to travel back in time without the possibility of carrying our lived experiences with us, it will be useless as we will be repeating the same mistakes over and over again. Now, this begs the questions “in what type of physique could we imagine ourselves back there if such time travel becomes possible? That is, becoming younger again in a physical regression (as I said this would be a torture without having learned from all these later years)? Or appearing at our desired times in our present physique and age? I believe the most ideal one would be if we appeared at our desired point in time at the same age that we were at that point of time with a good feeling of our later lived experiences.

Mam all u need to do is just run faster as much as u can or visit the black hole because in both condition time just slow it down ….

Time travel is simple. If you do happen to travel to the past you create a new time line not affecting the time line you left. In essence you going to the past is now your future. Even if you were able to return you may never know if you remained in your time-line or created a new one. So even if you changed something in your travels it would happen in the future not the past.

Sorry time traveling is not possible, there is no way you can go into the past or the future ‍♂️. You can only be in the time you are already in.

Incorrect. General relativity allows time travel into the future. You need a space ship that can travel extremely fast though, approaching the speed of light, or you need to get close to a supermassive black hole.

It is travel into the past that there is no known practical way to do, and is probably impossible.

So what happens when we Die? Where do we go? I want to go back in time so I can meet my childhood friends…

Simple question from a simple mind:

At what point, when a person says they are from the future, do we stop throwing them in the funny farm and actually start listening??

When they show actual proof. Not just some random prediction of the future.

I don’t believe that “glimpses into the future” could be possible. If it were so, we could glimpse blueprints of the future that we could bring back to the present and build before they were invented. My personal.beleif is in any time frame there is only one active time which is the present. The past no longer exists and the future hasn’t occurred yet, so there is no such thing as ‘time travel’ except for the frame we are in now.

First off time is not real we make time if you travel anywhere all you are doing is beating the Earth speed try this for a mathematical equation the Earth travels a thousand miles per hour you’re not beating human time that is your own equation the Earth travels a thousand miles per hour a space shuttle travel 17,000 mph you can beat time that you made so time is not real you are only beating the Earth speed if you go in a space shuttle and go around the earth 17,000 miles per hour the Earth only travels a thousand miles per hour plus it has all types of gravitational pull from the Moon Earth’s access on the til t you figure out the mathematical equation I cannot time travel is real if you can beat the Earth speed and we can it has nothing to do with its 12:00 it’s 1:00 that’s not real time is made up as a mathematical equation you can beat the Earth speed you can go back into the Earth’s time in a space shuttle but you’re not beating anything except the Earth’s speed think about that one time is not real at all all it is is a mathematical equation think about that one real long

What I’m trying to say is this a space shuttle travel 17,000 mph the Earth travels a thousand you beat it 16 times faster that’s all you did you’re not beating any time you’re not beating 1:00 you’re not beating 3:00 all you’re doing is beating the Earth’s time you can go in reverse around the Earth 17,000 mph okay you can go forward with the Earth’s centrifugal force 17,000 miles per hour you’re not beating anything you’re beating a mathematically equation that we we created astronauts been traveling time for instance for years and haven’t told us because of the space shuttle that does travel 17,000 mph it beats the Earth speed 16 times a boggles my mind you have the Earth access the moon gravitational pull but you can get in a space shuttle and travel 17,000 miles per hour and beat the Earth’s speed 17 times think about it

If any scientist or anybody can actually answer this question how do you set up this equation with the Earth spinning a thousand miles per hour you have the moon pulling gravity the Earth’s access on until I want to know tell me then wondering for a while this equation popped into my head about 2 years ago I’m not a math whiz or anything I just thought about it weird how the mind works I’m not into space or any space stuff at all I’m Samanthas boy friend John antos wrote this

I liked your post and the knowledge you given. I also written a post on Time Travel.

how would any of that stuff be true because e’*34+Em would stop all the forss of vissecs and how would we do it if you now what i mean??? also thanks for the scuff for my project

I would love it if I had a real life time machine here with me now which could take me to anytime I want, the past, present or future. If I had a time machine here with me now, I would go to the past in September 2004 when I was born and give myself to another family that is actually rich and not this horrible family that I have now.

that not nice

Close but not quite right scientists of the idiotic variety, yes, you don’t want people to travel back in time to mess with their own pasts, of course, but you say it’s impossible, but it’s not, and I’m always ignored with my crazed crackpot theories, so what’s the harm in telling the truth as I see it, while it could be possible to travel to the past, here in lies the problem with rewriting the future, while some believe it’s possible to travel back in time, but it’s very expensive and definitely a one-way trip to the future or to the past. Basically Doc Brown got the mechanism for time travel almost right but the energy out put needs to be quadrupled instead, allowing for the ‘physical item, being or vehicle’ to transport through time without killing the time traveler in question. Wormholes are unpredictable, until warp speed for spaceships are a thing, it is not possible for the space ships to achieve time travel, unless they want to enter a black hole, which I would not recommend. as you need warp speed to survive the emptiness of the black hole, without being ripped to shreds. Say for example, Back to the future 1, the timeline doesn’t erase it continues on without the ‘said time traveler’ in existence basically the Marty from Wimpy George’s timeline did time travel to the past and messed with his parent’s meeting so to speak, but never return to the same timeline therefore Marty A went known as a Missing Child in timeline A, while it continues on without him, however Marty A became Marty B/C, in the Successful George Timeline. So that is what I’m talking about. the timeline changes only for the time traveler themselves the ones who are left behind don’t experience a thing of timeline rewritten-ism, as it would never happen in the first place. The other thing is if you want to mess with your own childhood, to make a better life for the past self, the key thing to remember it’s not really you. It’s an alternative version of you, that you interfered with. creating a parallel timeline to it’s original, yet slightly different. Yes it would be awkward to raise yourself. but as long as you are staying in the past, nothing should happen until the age you traveled back in time, unless of course you touched your past self and suddenly de-aged and merged with your past self, is an option 1, option 2 the future self explodes spreading guts all over the place and therefore the past self, of you became a murderer of your future self, I am more inclined to believe option 1 as option 2 seems a little too out there. Basically you would have two memories one of the former timeline and one of the current different timeline. Still traveling through time is truly a one way trip and if you want to travel through time, you would need some time travel mechanism, the way you scientist talk is basically a dream version, or an OBE version (OUT-OF-BODY-EXPERIENCE) which is basically a vivid/lucid dream which is not true time travel, the true time travel is based on the BTTF Trilogy not the idiotic versions you preach about. I believe I’ve said enough.

Mystery solved and I will explain, I was in a coma 3 months and I experienced things, I traveled time forward and backward, it is not a one way ticket. Movies and songs are recorded on magnetic tape in a VCR tape Cartridge or Cassette tape, Magnetic tape recording works by converting electrical signals into magnetic energy, which imprints a record of the signal onto a moving tape covered in magnetic particles. 3D life on earth(a movie), and the Magnetosphere all around earth coming from the core of earth(MAGNETIC ACTIVITY) without Atom Made Tape, is like a movie on magnetic Atom made tape in a VCR tape cartridge. Revolution and Rotation is the motor(VCR).

This is why people have those freaky Deji’vu feelings like they have lived this before, BECAUSE YOU HAVE, and how people can be psychic, and how there is Prophecy in the Bible. When a person dies, their Spirit- MIND(Thoughts, Feelings, Urges(Physical and mental personality)) breaks out of human body- a stopped heart is what releases the spirit from the human body. Then the Soul(Life) with the memory of your existence in it breaks out of spirit and goes back to your birthday with a erased memory, meanwhile your spirit goes back in time to when you were a teenager starting the mental puberty, maturity from that adult spirit you died with in last life.In that old movie Star Wars or maybe it was the Empire Strikes Back, there is a scene where Princess Laya plays like a 3D movie, that is EXACTLY how its of life on earth.

If only wish I could undo everything what I’ve done wrong in the past, I’d be more happier

And that my friend is absolutely what you do not or would not know. Everyone focuses on what they don’t or haven’t had rather than what positives they do have around them. To change the ingredients of a past life only changes the flavour you have in this life, it does not make you happier.

No, travel to the future is not possible. Like, future is unpredictable and always have been so give up on that field

Already has been, and has been proven.

Time travel is not so possible for every one , but there are already time travelers on earth #@*

Who are these time travelers?

Depends if it is the Governments (they done it since the 80s), or if it was a Accidental travel, or a simple us creating our own machine. Either way, one can easily find storys, and other evidence with a good research. I have a website that shows the effects of change cause by time travel.

They are out their (done by the government since the 80s) but the future is open with time travel (told its open since 2028) so they travel back much.

Time travel 101-

Create a closed loop circuit around a full metal structure, hermetically seal it and bring O2, Use two tesla coils to create north and south poles. (Artificial Magneto sphere.) Make sure to pain the outside in lead to prevent any cosmic rays from penetrating the materials on the inside. (Radiation = bad). Connect a ball made of w/e with wires that alternate the current from the coils to w/e panel on the outside of the structure to make it move via inductive magnetic / electric Lorentzo (Lorentzo = ExMfield = Velocity. = Antigravity) Create Antigravity by using forces from the inside reactor. (Pressurized Mercury, and Tesla Turbine.) Then Move 10-100x faster than light depending on the charged field, Friction will be added to the electric field instead of the craft allowing the G-forces not to crush you inside. The field will take the pressures of outer space, The temperature of space will allow for super conductivity of the structure.

Eventually you will arrive in the future, if you stay in one place. but account for the movement of earth in your travel log. To see outside you will need a monitor / camera system, as any leaks through a viewing area will cause death by radiation from the cosmic rays from the field you have created.

The O2 can be used as a backup generator, through air pressure and the tesla turbine.

There are many different ways to make wormholes, but the curvature of space is really hard to calculate to send a machine far out to the end and create a link with the machine that wants to travel there. And leaving one behind to get back.

If you can imagine it, it can be done. You just need the knowledge of not dying to complete it.

U.S.S. Tourist, You’re a time traveler or just insanely smart.

You don’t need to go the speed of light. Human Time is recorded in the magnetospere as a movie is record, ed on magnet VCR Tape or a song on a record. A VCR or record does not have to go light speed to retrieve the recorded info. All of life is recorded in 3D by our Magnetosphere. My Analogy is imagine a VCR tape cartridge being the earth, imagine life on earth being the movie but in 3D with out adom made tape, imagine Rotation and Revolution of Earth being the VCR putting all in to motion- playing. That is how its done, the magnetosphere kills two birds with one stone, it protects earth and records time, human time is in a magnetic bubble that is why the Bible refers our time is different from gods time and this is how God the maker(PLANET OF UNITED SUPREME BEINGS) can flip through our time to know everything. By the way long before life on earth, he built the original 7 wonders of world(Pyramids) to Pump the Seven gasses into the atmosphere of this planet found in the goldilocks zone, so Life can live on it, and that life of all types is his technological cyborgs that grow and multiply on earth also he seeded it with plant, trees, sea creature and things that fly,. Anyway that above is how time is recorded.

Until recently, I thought my neighbor was a crackpot until he actually invented a time machine. He utilized an ordinary closet, and showed me the sophisticated (to me) instrumentation he had installed. I was very skeptical at first, until he offered a small demonstration and entered the time coordinates and energized his invention. To my amazement, when I opened the door, the clock on the wall was 30 minutes later than when we stepped into the machine. OMG!!! Destroy this thing before it destroys us!!!.

So happy to have my husband back after 6 months of separation. get any kind of relationship/marriage help you want from….Robinsonbuckler11 @gmail com………………………

I find it odd that people say time travel isn’t possible yet… If time travel is possible, it has always existed. Meaning, there is not past present it future, only our perception of time. What we know as past present and future have always been occurring simultaneously, so travel was invited the moment the universe wss formed. Dinosaurs are roaming the earth right now, and forever. A version of me is typing this and has always been typing this, within this perceived moment of “time” and time travel has always happened, whether or not we exist in that reality at the right “time” to observe time travel is the only question.

Their had to be one point however, when it was created and started, and for that, there was nothing but the current time. Once it was created, than we had a pass, present and future to which we can go back to millions of years to see Adam and Eve with the dinosaurs or go millions of years in the future. However, given the events that changes, each time a new time line has been created. We also have destroyed the planet and repopulated many times in the last million years. Each event changed, or something we do different (without traveling) enters a new universe where some things may be different or the same. Today are universe are shifting a lot.

To be fair, even if it is a one way trip into the past, that doesn’t stop machines going back. We could send a machine back and order it to do anything we want and then tell it to meet us at a certain time in the future. We send it back, then go straight to the meeting point we agreed and then we’ll be able to prove if it worked or not.

I’m a girl who has read a book about seeing future through a box. So is it actually possible?

Time travel has been done on purpose by the Government since the late 1980s. From research, the mostly use kids, or future Presidents. Their are some cases where people have been struck by lightning or came across some tragically event that cause them to leave their timeline either forward or behind in time. The Mandela Effect is the current cause of how things go wrong when time travel is not done right. Click on my name to see the website.

Even as traveling to a location as a future or pass date is possible as what people here mean. However, as you said, it is numbers. Time is a illusion and we do not travel threw time, just universe that are different than ours. What we call time dates and months is what changes each universe. We are all from different universes today as they came together. The mandela effect is a fine example.

thx to eleon wont we soon be able to digitize our conscious being, then accelerate that data pass the speed of light some how then download it into some android or something…..i dunno…..just a thought

I want to go to my elementary school again. Someone help me out, I know its Idiotic but stil.. I am not good at science. As far I understood, 1) we can trace through time if we travel fast than speed of light.. I think memory os the only thing that is faster than light, Yeah I can go to Paris within 1 sec in my memory but yeah its illustion, i want in real 2) Through Blackhole – I think its Bermuda triangle

if you travel back in time you will still be your age now. That is how it worked with others. No one gets younger otherwise traveling to far back would kill you. No school would let you return to school as a adult so not possible.

Plz help me I just want to send a message to myself in my past and save my self from a beast plz help Nazneen

Would love to experience many moments in life again for the first time again!

I think that time traveling should be left alone, for the sake of humanity. There are some things we’re not ready for yet.

Well stephen hawking may be wrong. I mean, the study proved that the universe self corrects itself to prevent inaccuracies. So maybe tourists from past do visit us but we don’t remember them as the universe alters our memory. If you guys have read about Butterfly Effect, a simple mistake today may grow through years to become a giant disaster in future so if you think of it, oncoming tourists from future may cause giant inaccuracies. Imagine this, You have travelled to past. You brought two cakes for yourself, so you pay the shopkeeper 20$. The shopkeeper invests the 20$ in stocks, strikes gold there and becomes a rich businessman.His daughter goes to Cambridge and marries someone else than the person she was supposed to marry according to time. Can you imagine the magnitude of inaccuracy after 100 years? Therefore, whatever the tourists from future do, is corrected by the universe and we don’t remember it. Creepy, but food for thought.It also adds a special meaning to the word ‘Fate’.

How much wacky terbacky (i.e. weed) you be smokin’ JOE JOE?

Hmmmm…. As brilliant of a mind as Stephen Hawkins was, how is he so sure that he would even recognize hordes of tourists from the future? Almost everyone is aware of the warning of the Butterfly Effect. So I’m sure any future visitors Intelligent enough for Past-Time travel would be amply attuned to this.

Most future people coming to the pass (our time) seems careless and not intelligent. Most are taking FBI lie detector test and telling us what is happening in the future. That is a bad idea, because if you tell us (example) who is the next President, and the Government does not like the person they than can change that event to let someone else in (as seen in 2020) One should never acknowledge who he or she is or why they are their. Most traveling is to get knowing of the pass or to pick up certain things. Since are pass is changing, events are changing and are timelines are messed up, someone made a mistake. The Mandela Effect is a fine example.

Wow that’s great plz help me go to my past plz,I can’t do it by my own at least help me send a msg to myself in my past Nazneen

I think it is possible, but time traveling is really just changing universe created by different time lines. Our whole solar system is in a whole different place now and Earth is much smaller in this universe from the one I grew up end. Someone has already changed the timeline.

Roads? Where we’re going, you don’t need roads!

Youre wrong about your measurement of speed for traveling, in order for time to slow down, with inside an object compared to outside. Scientists proved that time with inside an object at an excelorated speed actually appeared to have slown down during the duration of time for the test. The speed was far less then the terminal speed of a rocket for NASA at 256,000 kms p/h.

In to the volicity of space. Generating a vacuum of space, could be no different the the actual transport of matter over frequency where in fact matter can be carried by sound. It is believed that an alien civilization harnessed this energy in the form of bolisks that where believed to carry the same properities and in consideration of harmonic resinance, the simularities could be used in order to carry large weight. In accordance with a documentry on theoretical science.

However the properties, present the fact that a working property controdicts your counter intuative theory of gravitational deceloration of matter to colide within itself to absorb all things into non existance as to the transfer of matter into energy, rather then your idiolisms of transfer between dimentional space to another destination that is not linked or the transfer between time that isnt, either.

However to reproduce the fabric of time within space in a practical measurement as I have mentioned, would put an end to all the lunacy of an unmeasureable field, which people fail to identify. Like running into a glass window. Only to not know what forcefield is present.

Time travel into the past can be achieved simply going faster than the speed of light.

The closer you get to the speed of light the slower time goes

If you reach the speed of light time stops

If you go faster than the speed of light it starts to reverse

Why does no one seem to know this?

Christopher Reeves did this in Superman 3 brah.

Any time travel, pass and future, is by going faster than the speed of light. It is said by reversing that that you can go back in time. However, I assume since the Government has done this since the 80s they have better ways (maybe tying in a date) and not having to go to a unknown date.

I want to send a message to myself in the past on a particular date plz can you help me, this means a lot lot lot to me,plz help me Nazneen

Why don’t we drop the declaratory statements that it “is or isn’t possible!” Until someone actually does so. Just say “maybe”.

People have and their are records both to the pass and future. The Government has done it since the 80s as part of the “star wars project” and are much better at it today. This explains the black holes in the sky of 2019, and the CERN destroying 5 parallel universes in 2013. We also see changes because of time travel events changing time. The Mandela Effect is a find example.

I want to send a msg to myself and my family in the past ,is it possible plz help me my life will be saved one who helps me saves me and my kids from a pack of beasts,

The worst idea ever. We all want to do this and where does it stop. A lottery win does not sound bad if you knew the actual location, time and place. After a while though, would you not want to write that hit song, become the author of the Harry Potter books, stop 9/11? The idea of giving your pass self (a time time travel was not proven) information of the future could change things in a major way. This would cause one small thing to change creating many others to change. This has already happen in simple ways of the The Berenstein Bears changing to The Berenstain Bears. This is a small event but this event “The Mandela Effect” now has over 3,000 changes.

What if you decided to give your pass self information about a lottery ticket that would be a winner, bought late at night and he was hit by a car on the way to get it. Changes the whole future. However, If detailed right, done right, with no large changes, it may not effect much, but to know your being given info from yourself in a future time (when that was not known much or provrn back than) You would either assume it is a joke or you gone crazy.

I don’t want to win a lottery, my decision about my career and studying was right but my family and their cruelty has put me into this worst condition I just want to go back complete my studies and live a life like a human not like a animal or slave,help me plz Nazneen

Can someone take me to 2013? i can pay later to all of you in bitcoins so its a win win and you dont need to do anything, just wait

LOL but still complicating on my side

You travel in your dreams where time and space colloids ..That’s y sometimes the dream which you dreamt might be a 10 mins reel time but you felt dreaming whole time like 6 to 8hrs .. Probably even traveling to parallel universe

I agree. Dreams as we know it is not a simple sleep. The part of the brain we do not use while awake, we use at night. This is the phenomenon part of the brain that can do thing we feel a human can not do. We of course use less than 30% of our brain. By the use of 100% of the brain we would use both sides and be able to do common things such as read thoughts, move things without touching them etc. The idea of using this side of the brain, would be the theory we can leave our bodies and visit different universe, see what could of happen shall we done something different, and even see future events. This may be why we notice different memories to some things as we could of held some from another reality.

It would be very weird, however, if we were trapped in that universe, or another body and fail to return to ours. Is that how people die in their sleep?

i just fell like going to late 70’s, where i can see majority of family.. i am willing to trade life for it…..

Time travel to the pass is just as common as the future. However, as both has been done it is NOT travel threw time. Time is a illusion we created. We are actually traveling threw different universe with (what we call) different time, dates, years, etc. The Mandela Effect is a find example how traveling threw different reality’s change the time lines.

As a add on to the above, Time travel is not a theory, has been proven, and has been done by the Government since the 1980s. Their is many residue in our history to even show some time travel storys to be real.

Where can one get a reverse watch, is it really possible to go back in past with its help, is it sooo easy ,plz help me ??????? Nazneen

US20060073976A1- search this patent number,this describes the process for time travelling,I really don’t think magnetic energy will work,maybe heat focused on a specific point could expand the fabric of space and make a hole in it.even then I will the hole take you to another time.it would be one thing to time travel but selecting a point in time would be impossible.you could only travel to the time you device was built?

Is there a watch which back travels in time or reverse time watch? Is it true? How to get one? But with that how can I send a message to myself in my past, plz help Nazneen

I don’t believe such a watch exist and their are plenty of smart minds with huge funds trying to travel.right now there are only theories.

Thank you very much for your response. I just want to send a message to myself in my past. Nothing much will be changed but 3 literally dying devastating lives will be saved. We are suffering for the mistakes and egoistic arrogance of others so if possible plz help me

Traveling back in time isn’t just a when problem, it’s a *where* problem. Where was the place you’re standing right now a thousand years ago, or a thousandth of a second ago? There is no useful answer to those questions, so there’s nowhere to travel back in time to.

Traveling forward in time? You’re doing it now.

when you step through a door is time lost when you come back through? lets say you return days Later how much time did you loose. what exactly is Time,.? is dialation a safe way to return ,. a Blackhole will assist you in in travel, the question is will you arrive safe,.

Traveling back in time is impossible. 2 reasons why that are never taken into account.

A) The stuff you are made of ( subatomic material) is being used by something else. It I not like you are a facsimile of the already existing material. What you are made of is exactly the same existing material. The problem is exact stuff can not exist in 2 different places in the same point in time. You will either : Decompile or fall out of phase with the universe. Both bad outcomes for the time traveler.

B) Lets look at it from logical commonsense. You have a bar of gold . You intend to send the bar back 1 second in time. Now you have 2 bars of gold . You send those 2 bars back one second . You have 4 bars …… do that 50 times . You have over 900 trillion bars of gold. All made of the exact subatomic particles. The more the bars back the more the existing mass of the universe increase. What are the consequences of changing the mass of the universe . Hence the paradox . Information can not be destroyed., It also can not be created.

At least this is the way my brain perceives going back in time.

Time is a function of change. None of the 4 forces The strong force , The weak force , Electromagnetism and Gravity can not work without time.

I will figure out time travel one day but only for the past.

I wish I could travel back to 18th of June to save my mom.

Is time travel really a one way ticket? Theoretically, if you can go one way, you should be able to go back.

Time is not one way. It’s consequences are however irreparable given certain circumstances and is not something that should be taken lightly or thought of in a manner of disregard. I’ve only very recently decided to take to your social platforms regarding space and time.

You can try finding me on Instagram. I’m not familiar with these platforms to better direct you there. My Instagram name is johnrvh

On Twitter it seems to be @_JohnRvH

If I go forward I will have to pay extra bills and taxes. I don’t think I can afford it.

You’re the first person I’ve come across in this timeline that has a sense of humor. Thankfully, going forward is not possible if that future hasn’t been created yet.

timetraval is no joke if its created the whole universe could go out of orbit.

Cauchy problem converging to non minimal terraces as t → +∞

Stephen Hawking may he rest in peace a genius but not all knowing. As far as he knows we haven’t been flocked by tourists, in the same maybe these UFO sightings are actually time travelers from the future coming to the past to view how we really lived why things really happened the way they did, etc. To limit the imagination of possible and impossible is wrong then you create fantasy. And we have learned from history that there is truth in fantasy. I.e. the different mythos of the different ancient cultures from around the world including those of the Norse. Improbable and probable should be more appropriate. It’s possible because it can be imagined improbable die to the right math or this or that not existing or matching up. I also believe that if time travel to the past were possible that the changing of something in the past would create a new timeline running current with your timeline at which will inevitably collide and will cause the collapse of the universe at which point a new universe will be born.

so i think the speed of light is only relative to deciding a point of destination -initially- as specific gravity of destination needs to be ascertained to calculate the frequency needed to run an alcubierre-white engine to bend space correctly to cross space ‘quickly’, the point of reference may well be jupiter in our solar system for the fact of the moons that orbit it, i surmise that by using a ‘dead end ‘ equation that usually puts notable mathematicians into the outer regions by trying to solve it may actually be the key as calculations end in a loop of 4-2-1 ie 3N+1; this process of calculation creates a sine wave over time/distance relative to specific gravity of chosen destination – as time is determined by gravity therefore if the speed of light to a destination can be used to ascertain the specific gravity of a ‘body’ to visit ie a star or sun due to receivable resonant frequencies emitted by the body, then the constrictions of the speed of light do not exist other than to give a constant, by using the 3N+1 method of calculation ,once the speed of light and returning resonant frequencies of a destination are determined the calculation can be extrapolated to match the distance giving the end point -in doing this the sine wave required can be ascertained and be condensed to create a wormhole and allow the alcubierre-white engine to ‘bend or distort space enough so that the bubble you are in matches the required specific gravity of the destination – the frequency of the body nearest to the destination point should be used and resonated inside the bubble to create synchronicity of frequency and cause attraction i also believe that travelling through space require the ability to see things from different perspectives and it requires the ability to navigate through a series of what may be described as “Aims Windows” where your point of view needs to change inherently with a given position at a given point in the galaxy

Is Time Travel Possible?

The laws of physics allow time travel. So why haven’t people become chronological hoppers?

By Sarah Scoles

In the movies, time travelers typically step inside a machine and—poof—disappear. They then reappear instantaneously among cowboys, knights or dinosaurs. What these films show is basically time teleportation .

Scientists don’t think this conception is likely in the real world, but they also don’t relegate time travel to the crackpot realm. In fact, the laws of physics might allow chronological hopping, but the devil is in the details.

Time traveling to the near future is easy: you’re doing it right now at a rate of one second per second, and physicists say that rate can change. According to Einstein’s special theory of relativity, time’s flow depends on how fast you’re moving. The quicker you travel, the slower seconds pass. And according to Einstein’s general theory of relativity , gravity also affects clocks: the more forceful the gravity nearby, the slower time goes.

“Near massive bodies—near the surface of neutron stars or even at the surface of the Earth, although it’s a tiny effect—time runs slower than it does far away,” says Dave Goldberg, a cosmologist at Drexel University.

If a person were to hang out near the edge of a black hole , where gravity is prodigious, Goldberg says, only a few hours might pass for them while 1,000 years went by for someone on Earth. If the person who was near the black hole returned to this planet, they would have effectively traveled to the future. “That is a real effect,” he says. “That is completely uncontroversial.”

Going backward in time gets thorny, though (thornier than getting ripped to shreds inside a black hole). Scientists have come up with a few ways it might be possible, and they have been aware of time travel paradoxes in general relativity for decades. Fabio Costa, a physicist at the Nordic Institute for Theoretical Physics, notes that an early solution with time travel began with a scenario written in the 1920s. That idea involved massive long cylinder that spun fast in the manner of straw rolled between your palms and that twisted spacetime along with it. The understanding that this object could act as a time machine allowing one to travel to the past only happened in the 1970s, a few decades after scientists had discovered a phenomenon called “closed timelike curves.”

“A closed timelike curve describes the trajectory of a hypothetical observer that, while always traveling forward in time from their own perspective, at some point finds themselves at the same place and time where they started, creating a loop,” Costa says. “This is possible in a region of spacetime that, warped by gravity, loops into itself.”

“Einstein read [about closed timelike curves] and was very disturbed by this idea,” he adds. The phenomenon nevertheless spurred later research.

Science began to take time travel seriously in the 1980s. In 1990, for instance, Russian physicist Igor Novikov and American physicist Kip Thorne collaborated on a research paper about closed time-like curves. “They started to study not only how one could try to build a time machine but also how it would work,” Costa says.

Just as importantly, though, they investigated the problems with time travel. What if, for instance, you tossed a billiard ball into a time machine, and it traveled to the past and then collided with its past self in a way that meant its present self could never enter the time machine? “That looks like a paradox,” Costa says.

Since the 1990s, he says, there’s been on-and-off interest in the topic yet no big breakthrough. The field isn’t very active today, in part because every proposed model of a time machine has problems. “It has some attractive features, possibly some potential, but then when one starts to sort of unravel the details, there ends up being some kind of a roadblock,” says Gaurav Khanna of the University of Rhode Island.

For instance, most time travel models require negative mass —and hence negative energy because, as Albert Einstein revealed when he discovered E = mc 2 , mass and energy are one and the same. In theory, at least, just as an electric charge can be positive or negative, so can mass—though no one’s ever found an example of negative mass. Why does time travel depend on such exotic matter? In many cases, it is needed to hold open a wormhole—a tunnel in spacetime predicted by general relativity that connects one point in the cosmos to another.

Without negative mass, gravity would cause this tunnel to collapse. “You can think of it as counteracting the positive mass or energy that wants to traverse the wormhole,” Goldberg says.

Khanna and Goldberg concur that it’s unlikely matter with negative mass even exists, although Khanna notes that some quantum phenomena show promise, for instance, for negative energy on very small scales. But that would be “nowhere close to the scale that would be needed” for a realistic time machine, he says.

These challenges explain why Khanna initially discouraged Caroline Mallary, then his graduate student at the University of Massachusetts Dartmouth, from doing a time travel project. Mallary and Khanna went forward anyway and came up with a theoretical time machine that didn’t require negative mass. In its simplistic form, Mallary’s idea involves two parallel cars, each made of regular matter. If you leave one parked and zoom the other with extreme acceleration, a closed timelike curve will form between them.

Easy, right? But while Mallary’s model gets rid of the need for negative matter, it adds another hurdle: it requires infinite density inside the cars for them to affect spacetime in a way that would be useful for time travel. Infinite density can be found inside a black hole, where gravity is so intense that it squishes matter into a mind-bogglingly small space called a singularity. In the model, each of the cars needs to contain such a singularity. “One of the reasons that there's not a lot of active research on this sort of thing is because of these constraints,” Mallary says.

Other researchers have created models of time travel that involve a wormhole, or a tunnel in spacetime from one point in the cosmos to another. “It's sort of a shortcut through the universe,” Goldberg says. Imagine accelerating one end of the wormhole to near the speed of light and then sending it back to where it came from. “Those two sides are no longer synced,” he says. “One is in the past; one is in the future.” Walk between them, and you’re time traveling.

You could accomplish something similar by moving one end of the wormhole near a big gravitational field—such as a black hole—while keeping the other end near a smaller gravitational force. In that way, time would slow down on the big gravity side, essentially allowing a particle or some other chunk of mass to reside in the past relative to the other side of the wormhole.

Making a wormhole requires pesky negative mass and energy, however. A wormhole created from normal mass would collapse because of gravity. “Most designs tend to have some similar sorts of issues,” Goldberg says. They’re theoretically possible, but there’s currently no feasible way to make them, kind of like a good-tasting pizza with no calories.

And maybe the problem is not just that we don’t know how to make time travel machines but also that it’s not possible to do so except on microscopic scales—a belief held by the late physicist Stephen Hawking. He proposed the chronology protection conjecture: The universe doesn’t allow time travel because it doesn’t allow alterations to the past. “It seems there is a chronology protection agency, which prevents the appearance of closed timelike curves and so makes the universe safe for historians,” Hawking wrote in a 1992 paper in Physical Review D .

Part of his reasoning involved the paradoxes time travel would create such as the aforementioned situation with a billiard ball and its more famous counterpart, the grandfather paradox : If you go back in time and kill your grandfather before he has children, you can’t be born, and therefore you can’t time travel, and therefore you couldn’t have killed your grandfather. And yet there you are.

Those complications are what interests Massachusetts Institute of Technology philosopher Agustin Rayo, however, because the paradoxes don’t just call causality and chronology into question. They also make free will seem suspect. If physics says you can go back in time, then why can’t you kill your grandfather? “What stops you?” he says. Are you not free?

Rayo suspects that time travel is consistent with free will, though. “What’s past is past,” he says. “So if, in fact, my grandfather survived long enough to have children, traveling back in time isn’t going to change that. Why will I fail if I try? I don’t know because I don’t have enough information about the past. What I do know is that I’ll fail somehow.”

If you went to kill your grandfather, in other words, you’d perhaps slip on a banana en route or miss the bus. “It's not like you would find some special force compelling you not to do it,” Costa says. “You would fail to do it for perfectly mundane reasons.”

In 2020 Costa worked with Germain Tobar, then his undergraduate student at the University of Queensland in Australia, on the math that would underlie a similar idea: that time travel is possible without paradoxes and with freedom of choice.

Goldberg agrees with them in a way. “I definitely fall into the category of [thinking that] if there is time travel, it will be constructed in such a way that it produces one self-consistent view of history,” he says. “Because that seems to be the way that all the rest of our physical laws are constructed.”

No one knows what the future of time travel to the past will hold. And so far, no time travelers have come to tell us about it.

Is Time Travel Possible?

We all travel in time! We travel one year in time between birthdays, for example. And we are all traveling in time at approximately the same speed: 1 second per second.

NASA's space telescopes also give us a way to look back in time. Telescopes help us see stars and galaxies that are very far away . It takes a long time for the light from faraway galaxies to reach us. So, when we look into the sky with a telescope, we are seeing what those stars and galaxies looked like a very long time ago.

However, when we think of the phrase "time travel," we are usually thinking of traveling faster than 1 second per second. That kind of time travel sounds like something you'd only see in movies or science fiction books. Could it be real? Science says yes!

How do we know that time travel is possible?

More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together. Einstein also said our universe has a speed limit: nothing can travel faster than the speed of light (186,000 miles per second).

What does this mean for time travel? Well, according to this theory, the faster you travel, the slower you experience time. Scientists have done some experiments to show that this is true.

For example, there was an experiment that used two clocks set to the exact same time. One clock stayed on Earth, while the other flew in an airplane (going in the same direction Earth rotates).

After the airplane flew around the world, scientists compared the two clocks. The clock on the fast-moving airplane was slightly behind the clock on the ground. So, the clock on the airplane was traveling slightly slower in time than 1 second per second.

Can we use time travel in everyday life?

We can't use a time machine to travel hundreds of years into the past or future. That kind of time travel only happens in books and movies. But the math of time travel does affect the things we use every day.

For example, we use GPS satellites to help us figure out how to get to new places. (Check out our video about how GPS satellites work .) NASA scientists also use a high-accuracy version of GPS to keep track of where satellites are in space. But did you know that GPS relies on time-travel calculations to help you get around town?

GPS satellites orbit around Earth very quickly at about 8,700 miles (14,000 kilometers) per hour. This slows down GPS satellite clocks by a small fraction of a second (similar to the airplane example above).

However, the satellites are also orbiting Earth about 12,550 miles (20,200 km) above the surface. This actually speeds up GPS satellite clocks by a slighter larger fraction of a second.

Here's how: Einstein's theory also says that gravity curves space and time, causing the passage of time to slow down. High up where the satellites orbit, Earth's gravity is much weaker. This causes the clocks on GPS satellites to run faster than clocks on the ground.

The combined result is that the clocks on GPS satellites experience time at a rate slightly faster than 1 second per second. Luckily, scientists can use math to correct these differences in time.

If scientists didn't correct the GPS clocks, there would be big problems. GPS satellites wouldn't be able to correctly calculate their position or yours. The errors would add up to a few miles each day, which is a big deal. GPS maps might think your home is nowhere near where it actually is!

In Summary:

Yes, time travel is indeed a real thing. But it's not quite what you've probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second. And there are important reasons why we need to understand this real-world form of time travel.

Looks like time travel is possible... for particles of light. 

Using a photon, physicists have managed to simulate quantum particles traveling through time . Studying the photon’s behavior could help scientists understand some inexplicable aspects of modern physics.  

"The question of time travel features at the interface between two of our most successful yet incompatible physical theories -- Einstein's general relativity and quantum mechanics," University of Queensland’s Martin Ringbauer says in a news release . "Einstein's theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules."

Time slows down or speeds up depending on how fast you move relative to another object . Einstein's theory suggests the possibility of traveling backwards in time by following a space-time path that returns to the starting point in space -- but at an earlier time. This is called a closed timelike curve (pictured above). It’s a traversable wormhole. 

In a quantum regime, the authors say, the paradox of time travel can be resolved, leaving closed timelike curves consistent with relativity. Near a black hole, for example, the extreme effects of general relativity play a role. 

Pictured above, a space-time structure exhibiting closed paths in space (horizontal) and time (vertical). A quantum particle travels through a wormhole back in time and returns to the same location in space and time.

"The properties of quantum particles are 'fuzzy' or uncertain to start with, so this gives them enough wiggle room to avoid inconsistent time travel situations," UQ’s Tim Ralph explains . "Our study provides insights into where and how nature might behave differently from what our theories predict." These include the violation of Heisenberg's uncertainty principle, cracking of quantum cryptography, and perfect cloning of quantum states. 

The work was published in Nature Communications this week.

Will it ever be possible for time travel to occur? – Alana C., age 12, Queens, New York

Have you ever dreamed of traveling through time, like characters do in science fiction movies? For centuries, the concept of time travel has captivated people’s imaginations. Time travel is the concept of moving between different points in time, just like you move between different places. In movies, you might have seen characters using special machines, magical devices or even hopping into a futuristic car to travel backward or forward in time.

But is this just a fun idea for movies, or could it really happen?

The question of whether time is reversible remains one of the biggest unresolved questions in science. If the universe follows the laws of thermodynamics , it may not be possible. The second law of thermodynamics states that things in the universe can either remain the same or become more disordered over time.

It’s a bit like saying you can’t unscramble eggs once they’ve been cooked. According to this law, the universe can never go back exactly to how it was before. Time can only go forward, like a one-way street.

Time is relative

However, physicist Albert Einstein’s theory of special relativity suggests that time passes at different rates for different people. Someone speeding along on a spaceship moving close to the speed of light – 671 million miles per hour! – will experience time slower than a person on Earth.

People have yet to build spaceships that can move at speeds anywhere near as fast as light, but astronauts who visit the International Space Station orbit around the Earth at speeds close to 17,500 mph. Astronaut Scott Kelly has spent 520 days at the International Space Station, and as a result has aged a little more slowly than his twin brother – and fellow astronaut – Mark Kelly. Scott used to be 6 minutes younger than his twin brother. Now, because Scott was traveling so much faster than Mark and for so many days, he is 6 minutes and 5 milliseconds younger .

Some scientists are exploring other ideas that could theoretically allow time travel. One concept involves wormholes , or hypothetical tunnels in space that could create shortcuts for journeys across the universe. If someone could build a wormhole and then figure out a way to move one end at close to the speed of light – like the hypothetical spaceship mentioned above – the moving end would age more slowly than the stationary end. Someone who entered the moving end and exited the wormhole through the stationary end would come out in their past.

However, wormholes remain theoretical: Scientists have yet to spot one. It also looks like it would be incredibly challenging to send humans through a wormhole space tunnel.

Paradoxes and failed dinner parties

There are also paradoxes associated with time travel. The famous “ grandfather paradox ” is a hypothetical problem that could arise if someone traveled back in time and accidentally prevented their grandparents from meeting. This would create a paradox where you were never born, which raises the question: How could you have traveled back in time in the first place? It’s a mind-boggling puzzle that adds to the mystery of time travel.

Famously, physicist Stephen Hawking tested the possibility of time travel by throwing a dinner party where invitations noting the date, time and coordinates were not sent out until after it had happened. His hope was that his invitation would be read by someone living in the future, who had capabilities to travel back in time. But no one showed up.

As he pointed out : “The best evidence we have that time travel is not possible, and never will be, is that we have not been invaded by hordes of tourists from the future.”

Telescopes are time machines

Interestingly, astrophysicists armed with powerful telescopes possess a unique form of time travel. As they peer into the vast expanse of the cosmos, they gaze into the past universe. Light from all galaxies and stars takes time to travel, and these beams of light carry information from the distant past. When astrophysicists observe a star or a galaxy through a telescope, they are not seeing it as it is in the present, but as it existed when the light began its journey to Earth millions to billions of years ago.

NASA’s newest space telescope, the James Webb Space Telescope , is peering at galaxies that were formed at the very beginning of the Big Bang, about 13.7 billion years ago.

While we aren’t likely to have time machines like the ones in movies anytime soon, scientists are actively researching and exploring new ideas. But for now, we’ll have to enjoy the idea of time travel in our favorite books, movies and dreams.

13 Best Time Travel Books Ever (Modern and Classic)

By: Author Jess Esa and Willow Heath

Posted on Last updated: 3rd April 2024

Time travel is an element of storytelling that offers potentially limitless possibilities, allowing writers to explore politics, romance, warfare, discovery, and more in ways we might never expect.

Since 1895, with the publication of H.G. Wells’ The Time Machine (below), time travel stories in modern fiction have inspired and captivated readers around the world.

It isn’t only the genre of science fiction that utilises time travel, however. Many of the best time travel books are love stories, crime thrillers, and even fantasy novels.

Essential Time Travel Books

Because of the breadth of scope and possibility that time travel can offer, what you’ll find here is a spectrum of genres and styles from writers of all different walks of life.

Some of these time travel books are deeply allegorical and political, using time travel to make strong and noble points about modern society.

Others use time travel as a savvy storytelling technique to present readers with fantastic romance and thriller narratives.

There’s something for everyone here in this selection of the best time travel books ever written.

This Is How You Lose the Time Way by Amal El-Mohtar & Max Gladstone

This is How You Lose the Time War is a stunning piece of time travel science fiction, co-written by two celebrated sci-fi authors.

Here’s one of the most unique time travel romance books you’ll ever read. Our protagonists, known only as Red and Blue, are deadly agents who operate for rival factions which are fighting for control of multiple timelines.

While wandering the remains of a mecha battlefield, Red finds a letter left for her by Blue.

The letter taunts and teases Red, but also hints that Blue is becoming disenchanted by this ceaseless and seemingly endless, ultimately pointless war between their factions.

From this point on, we shift narratives between both characters’ perspectives, and those perspectives are separated by letters they leave for each other to find.

As they move through various strands of time that shift back and forth through possible pasts and futures, each finds a letter left by the other, and these letters steadily take on a different, more poetic and romantic tone.

From flirtatious taunts to passionate declarations of love, the letters steadily spell out the intense addiction that these two opposing women have developed for one another.

This is one of those time travel books with larger-than-life concepts that involve time manipulation and riding the threads of time, taking us from Plato’s Greece to mech wars on distant planets.

This is a wildly exciting time travel romance novel that shows us how, no matter the scale of the world, no matter the advancements in technology, love can still win in the end.

Before The Coffee Gets Cold by Toshikazu Kawaguchi

Translated from the Japanese by Geoffrey Trousselot

In a Tokyo café that has stood since the Edo period sits is a chair at the furthest point from the door. Local legend says this chair can transport you back through time, provided you follow a specific set of rules.

The legend is true, as Fumiko soon discovers when her boyfriend abruptly leaves her for a job in the US and she’s willing to do anything to go back in time and stop him.

Before the Coffee Gets Cold opens with Fumiko meeting with her boyfriend for what he calls a ‘serious conversation’. She hopes for a proposal, but he hits her with a break-up instead.

Goro moves to the US and a week goes by for the pining, mourning Fumiko, who continues to visit the café.

When Fumiko recalls the local urban myth surrounding the time-travelling chair, she asks the café’s staff if there’s any truth to it.

There is, but if the rules aren’t adhered to, there are dire consequences.

First, you cannot leave the chair. Second, whatever you say or do will not alter the present.

Finally, there is a time limit: the journey through time begins when the coffee is poured, and you must finish it before the coffee gets cold.

If you don’t, you take the place of the woman who is almost always sat in that chair; a woman who turns out to be a ghost. She leaves the chair to visit the toilet once a day, and that’s when you can sit and travel back.

Try to move her by force and she will curse you, as Fumiko finds out. This woman was the last person who let the coffee go cold, and now remains there always as a ghost.

Before the Coffee Gets Cold isn’t only one of the most unique and compelling time travel books of recent years, but is also one of the most celebrated Japanese novels of our time.

Outlander by Diana Gabaldon

Outlander is an enormous success story; a series of time travel books that have an ongoing history of more than thirty years. Add to this the huge popularity of the Outlander TV series.

The first novel in the series introduces us to protagonist Claire Randall, a British Army nurse who served during World War II.

Having been reunited with her husband after the end of the war, the two take a second honeymoon to Inverness, Scotland.

While gathering plants, Claire is drawn to, and touches, a standing stone (solitary monoliths known as a menhir, which date back to Bronze Age Scotland).

Upon touching the stone, Claire passes out and wakes up centuries into the past, in the year 1743.

This is a world she doesn’t know, one torn apart by politics, warfare, and bloodshed. There, she will be tempted by love as she falls for a man who is everything her 20th century husband is not.

Outlander has become one of the great and iconic time travel romance books of our time, and the series’ popularity only continues to grow.

The Time Machine by H.G. Wells

This is where modern time travel stories began, with H.G. Wells’ sci-fi masterpiece, The Time Machine , which has been adapted to film twice.

As a side note, the original 1960 film starring Rod Taylor remains a fantastic piece of sci-fi cinema; a must-watch classic.

Wells’ original novel was published in 1895 and set the stage for all the best time travel books that would follow.

The premise is simple: an inventor builds himself a time machine, and that machine carries him forward in time.

But while most time travel books focus on a future that remains relatable, understandable, and potentially possible, The Time Machine goes far beyond any of that.

Our scientist arrives in the year 802701 CE, an eerie future in which human evolution split into two very different groups.

The first group are the naive, child-like Eloi, who live in blissful peace and harmony, with all their needs provided to them.

The other group live underground, and they are the cannibalistic Morlocks, who feed on the Eloi.

As a socialist, Wells was critical of many aspects of European society during his time, and his novels were allegorical of the things he disagreed with.

This can be seen in The War of the Worlds , an anti-colonialism story. And it can also be seen here, with The Time Machine being a critique of class disparity and social inequality.

The Time Machine remains one of the most valuable time travel books ever written, by the godfather of modern science fiction .

11/22/63 by Stephen King

Stephen King is best known for his twisted horror novels — many of which have been adapted to film and TV — as well as his surreal fantasy epic , The Dark Tower .

But King has also penned a few excellent thrillers , and this is one of his very best. Beyond that, it’s also one of the coolest time travel books of this century.

In 11/22/63 , an English teacher named Jake is shown a wormhole that leads to the late 1950s.

A friend convinces him to use his time in the past to attempt the noble task of stopping the assassination of President John F. Kennedy.

Jake and the reader soon learn that the past may be changed for the better but the future may not react so positively. 

Another great aspect to this time travel book is the relationship between Jake and his love interest, Sadie.

Both bring incredible warmth to a novel which, rather than just being a tense thriller, becomes one of the most surprising time travel romance books to boot.

The Seven Deaths of Evelyn Hardcastle by Stuart Turton

The Seven Deaths of Evelyn Hardcastle is a puzzle box of a mystery novel that employs time travel and time loop rules to deliver one of the smartest, most captivating mystery plots you’ll ever read.

We begin halfway through a word that has just left the mouth of our nameless, amnesia-stricken protagonist. It is as though he has just woken up inside his own body.

He is in a forest, shouting a name he doesn’t know, and he is alone. That’s all we know, and it’s all he knows, too.

He walks, and eventually arrives at a manor house. The people there tell him he is their friend, that he is a doctor, and that he’s there for a party, just like they are.

The next morning, he wakes up as a different person in the house, and it is then that he learns that he will continue to jump from body to body for eight days, tasked with solving and preventing the death of the titular Evelyn Hardcastle.

The Seven Deaths of Evelyn Hardcastle is a dizzying mystery novel, masterfully crafted and thrilling at every turn. Of all the time travel books you’ll ever read, none handle the mechanics of time like this one does.

Kindred by Octavia E. Butler

A generation-defining science fiction novel and one of the best pieces of American fiction ever written, Kindred is a true masterpiece amongst time travel books, and science fiction in general.

When the novel begins, Dana and Kevin are unpacking after moving to a new house in California, when she finds herself teleported back 150 years to a plantation in 1815 Maryland and the sight of a drowning red-headed boy.

Dana saves the boy from drowning and immediately finds herself facing down the barrel of a white man’s gun, before being yanked back through time to her present in the 1970s.

As it transpires, the drowning boy is Rufus, an ancestor of Dana’s who will father a child with one of his family’s slaves, and Dana is now caught in a loop: any time Rufus’ life is threatened, she is pulled in time back to save him.

Similarly, if she is put in harm’s way while in the past, she is sent back to 1976. On her third journey back to 1815, her husband is dragged back with her by accident, raising the stakes even higher.

Being a Black woman married to a white man, Dana is assumed a slave, and Kevin her owner. Kindred is a sci-fi time travel novel about cruelty and compassion, about the importance of education and empathy.

A true masterpiece amongst time travel books by one of the USA’s most important literary voices, Octavia Butler’s Kindred is one of the most important American novels you’ll ever read; a masterpiece of time travel sci-fi.

Night Watch by Terry Pratchett

Terry Pratchett was a genius author, of that there is no debate . His Discworld series of fantasy books provided an enormous, expansive, satirical world of possibilities and endless narrative potential.

As we journey across the Discworld, we follow a handful of different protagonists, including Death himself. One of the most beloved protagonists is Sam Vimes, captain of the Ankh Morpork city watch.

In Night Watch , while Sam Vimes’ wife is in labour and he is in heroic pursuit of a known criminal, the city watch captain is hit by lightning and sent backwards in time.

Vimes is quickly arrested by a younger, less experienced version of himself, and in the cell beside his is the very criminal he was chasing across the rooftops in his own present day.

Night Watch is another fantastic Discworld novel, presenting an entirely new side to a fan-favourite protagonist, and is one of the most creative and hilarious time travel books you’ll ever read.

Sea of Tranquility by Emily St John Mandel

With Sea of Tranquility , beloved contemporary author Emily St. John Mandel has written a phenomenal piece of time travel science fiction which surpasses even Station Eleven , her most successful novel.

Cleverly tied to her literary thriller The Glass Hotel with recurring events and characters from that novel, this is a book that unfurls gradually and strangely, creating a kind of symmetry with itself by the final page.

We begin in 1912, with an English nobleman exiled to the rural wilds of western Canada by his family. Then we move to the modern day, with characters from The Glass Hotel revealing what almost seems like a glitch in the world.

Next is the life of an author who grew up on a moon colony and is now doing a global book tour in 2203, just as a pandemic is about to sweep the planet.

Finally, at the book’s halfway point, we meet our true protagonist: a man named Gaspery, whose sister works for a time travel agency.

From here, we begin to move backwards through the time periods and lives we’ve already seen, as the truth gradually gets revealed and explored.

All of these lives become stitched together as this time travel novel progresses, in ways that will blow your mind over and over again. The plotting of this novel is beaten only by its incredibly revelations.

Sea of Tranquility is a true masterpiece of plotting and tone, moving with speed and grace. One of the best time travel books you’ll ever read.

Slaughterhouse Five by Kurt Vonnegut

No other author has ever written, or even thought, like Kurt Vonnegut did. He was a masterful satirist who used science fiction to explore the deep, dark political themes of the 20th century.

Written during the Vietnam War, and displaying aggressively blatant anti-war themes and messaging, Slaughterhouse-Five remains Vonnegut’s most celebrated novel, and for very good reasons.

Based in part on Vonnegut’s own life as a serviceman during World War II, Slaughterhouse-Five follows the life of a man named Billy Pilgrim.

Pilgrim was an American PoW who experienced and survived the firebombing of Dresden, and who later was abducted by aliens and taken to a planet called Tralfamadore.

We spend some of the novel living through Billy’s experiences through World War II, then his life back home post-war, and finally his abduction by aliens and the time-twisting that follows.

It’s a strange time travel sci-fi novel that throws out surreal and dreamlike concepts about seeing in four dimensions, travelling through memories, and being held in an alien zoo.

Considered a work of postmodernism, Slaughterhouse-Five is an expressly anti-war book that explores this perspective through surreal science fiction and satire.

Blending war fiction , satire, science fiction, and time travel, Slaughterhouse Five does a lot of different things, and it does them all splendidly.

Hyperion by Dan Simmons

Dan Simmons excels at writing within and beyond the bounds of various different genres, from thrillers to historical fiction, to this: a time travel sci-fi novel based on The Canterbury Tales .

Set in a far-future in which a spacefaring human empire exists known as the Hegemony of Man, Hyperion follows a group of pilgrims who have arrived on the planet of Hyperion.

Hyperion is home to strange Time Tombs which move backwards in time, and are guarded by a strange native creature called the Shrike.

Modelled after Chaucer’s Canterbury Tales , Dan Simmons’ Hyperion is a time travel book that presents us with each pilgrim’s backstory, and what led them to the titular planet of Hyperion.

A wonderful exercise in world-building and sci-fi storytelling, Hyperion is a a trippy and strange novel, and one of the coolest, most experimental time travel books you’ll ever read.

The Time Traveller’s Wife by Audrey Niffinger

This 2003 novel has become an absolute classic amongst time travel romance books, and time travel books in general, propelled into the public consciousness by its film and TV adaptations.

Our dual protagonists are husband-and-wife pair Henry and Clare. Henry suffers from a strange disorder which the novel calls “Chrono-Impairment”. This disorder causes Henry to become frequently unshackled from time.

From a very young age, Henry has been periodically shot backwards in time. Each episode is entirely unpredictable, as is where he will go and how long he will be trapped there for.

Clare and Henry’s meetings have happened out of order, with Henry first laying eyes on her at the library where he works when they are both in their twenties. This, however, was not the first time Clare met Henry.

After they meet in the present, Henry begins to travel back into Clare’s past. Eventually, he provides her a with list that will tell her when in her life he will appear. He also reveals to young Clare that they will eventually be married.

Inspired by the author’s own romantic disappointments, The Time Traveler’s Wife has become one of the best-known, best-selling time travel books of all time.

Wrong Place Wrong Time by Gillian McAllister

Our protagonist, Jen, is waiting for her teenage son Todd to come home. He’s late; it’s after midnight, and when he eventually appears outside, Jen watches her son kill someone with her own eyes.

The police arrive, Todd is in possession of the knife, has the victim’s blood on his clothes, and his own mother saw it happen. What doubt could there be that Todd did what he did, even if we don’t know why?

But this isn’t where it ends. In fact, from this moment, Jen goes to sleep and wakes up a day earlier.

Every single night she goes to sleep and wakes up a day earlier, rather than later, as time steadily reverses day by day and she is given a chance to follow this thread back to its beginning, and its revelation.

A dizzying thriller that plays with the tropes of time travel in fun new ways. Mixing time travel and thrillers is nothing new, but the way that McAllister does it is fresh and addictive.

The time travel gimmick is one that’s arguably best utilised by thrillers and mystery novels, and this is a glowing example. One of the most addictive time travel books of recent years.

What To Expect From Time Travel Romance Books?

Wherever your time travel plot takes you, you can expect to be taken on an imaginative journey where love transcends time and space.

These books often feature strong-willed characters from different eras or dimensions, who find themselves drawn to each other even though they are separated by time or circumstance.

Being from different generations and time periods, there are often cultural clashes, and different opinions on values, morals, or ways of courtship.

The character dynamics are one of the biggest reasons to read a time travel romance book, and they will be sure to have you questioning your own values and morals in today’s world.

What We Know About The CIA's Alleged Secret Time Travel Program

In October of 1943, an alleged experiment took place at the Philadelphia Naval Shipyard that opened the proverbial door to time travel (via Military.com ). According to legend, the USS Eldridge (DE 173) — a Cannon-class battleship used primarily to hunt and destroy enemy submarines — left our timeline in an experiment in invisibility gone wrong, per USS Slater . Part of a CIA research project known as Project Rainbow , the alleged incident with the USS Eldridge at the Philadelphia Naval Yard has become unofficially known as "the Philadelphia Experiment," per  The Guardian .

In an effort to put an end to World War II, the story says that the U.S. military began experimenting with ways to end the dragging world war in the quickest, most efficient manner. One of the ideas floating around was the idea of cloaking — or making invisible to radar — battleships. Using a device called a "time zero generator," the military attempted to do just that, per  The Guardian . What allegedly happened, however, was completely unexpected.

Where did they go?

On October 28, 1943, the switch was allegedly thrown on the time zero generator. Eyewitness' claim to have seen the USS Eldridge suddenly begin to glow in a green-blue haze that surrounded the vessel (via Military.com ). The Eldridge began to fade, leaving just the outline of the ship remaining. And with that, the ship blinked out of existence, according to The Guardian . Time slowly ticked by. No one knew exactly what happened to the ship or where it went. After a long 20 minutes, the Eldridge reappeared, but with horrifying results. Much of the vessel was on fire, members of the crew — who allegedly left our reality along with the ship — were found insane. And those were the lucky ones. Reports swirl that many crew members of the Eldridge had "fused" with the ship upon its return to our reality; torsos, limbs, and other miscellaneous body parts were found amalgamated into the ship's steel hull.

A hoax or horrifying accident

According to the surviving members of the ship's crew, during the vessel's alleged 20-minute disappearance, the ship seemingly re-appeared 600 miles away in Newport News, located in Virginia. Of course,  The Guardian  calls the story "hokum" concocted by UFO enthusiast Carl Allen. And with no real concrete proof of the event ever taking place, the U.S. Navy outright denies the Philadelphia Experiment ever happened. 

Nevertheless, the USS Eldridge did exist — sold off to Greece in 1951 and finally decommissioned and sold for scrap in the '90s — and Project Rainbow did occur. But the Office of Naval Research (ONR) stated that force fields to make a ship invisible don't "conform to known physical laws" (via the Black Vault ).  Coupled with the fact that there are no official documents, military or otherwise about the event, it's very well likely the story of the Philadelphia Experiment is likely to remain just that ... a story.

Best 10 TV Shows About Time Travel Ultimate List

There have been numerous TV shows about time travel in the past. Although some shows did have time travel included in part of their plot (like Marvel Agents of Shield), in this list we focused on series that have time travel as a basic premise of the show. With that in mind, we narrowed down our picks to the top 10 TV series that are worth your time. However, keep in mind that there are other fantasy shows that you might like – this is just our pick of the best ones so far.

10.  Timeless [2016-2018]

A hidden gem among TV series about time traveling is NBC’s Timeless. The show is a quick watch – it only has two seasons and 28 episodes in total but don’t be discouraged by that fact. Timeless still manages to land a meaningful, educating, heart-warming story with a compelling ending. The cast features Abigail Spencer as Lucy Preston a history professor, Matt Lanter as Wyatt Logan, a USA Delta Force Sargeant, and Malcolm Barrett as Rufus Carlin, a programmer. The trio is tasked with capturing a terrorist Garcia Flynn (Goran Visnjic) who is trying to rewrite history.

Although the premise of the show looks very much like what we have seen in Continuum, Travelers and 12 Monkeys, Timeless also offers a variety of real historical events that are shown in the series. The historical part might not always be 100% accurate but it is fun to see the fictional characters interacting with real-life events that took place. Although the show was canceled after two seasons, the viewers still got a well-deserved ending so we highly recommend Timeless.

9. Continuum [2012-2015]

One of the classic TV shows that exploited the topic of time travel is Continuum. Stretching through 4 seasons and 42 episodes, Continuum tells a story about detective Kiera Cameron (Rachel Nichols) who goes back in time by accident with a group of criminals called Liber8. The plot takes place in present-day as Kiera tries to stop members of Liber8 from altering the timeline and destroying the future in which corporations have sized the roles of the governments. A teenage wunderkind Alec Sadler (Erik Knudsen) helps her out on her quest as well as her partner Carlos Fonnegra (Victor Webster). 

Although the plot seems like more of what we saw in some earlier TV shows about time travel, the cast does a pretty decent job and the overall setting is fun to watch. As you can see, this show has been produced more than a decade ago but the CGI elements are not that bad and are watchable. But what really gives Continuum a place on our list is the character development that Kiera as a protagonist goes through.

8. Quantum Leap [1989-1993]

Quantum Leap is an old-school TV show that older viewers must have watched during 90s. The importance of this show is the fact that after its initial success, many directors pitched ideas for similar shows in the future – and that’s how we got so many time travel series. Although Quantum Leap is highly praised, it is a bit outdated nowadays, so it might not be the best choice for younger viewers.

Be it as it may, the show focuses on Dr. Sam Beckett, who gets thrown back in time while experimenting on his own project (Quantum Leap). The protagonist is accompanied by his friend Admiral Al Calavicci (Dean Stockwell) but in the shape of a hologram. Dr. Beckett continues to leap to different people in his own timeline and hopes to correct the past in order to finally leap to the presence. Quantum Leap offers a unique mixture of science fiction, drama, and comedy all while exploring the topic of time traveling.

7. 12 Monkeys [2015-2018]

12 Monkeys is a sci-fi masterpiece remake of a 12 Monkeys movie (1995) that has time travel in the essence of its plot. As you might remember from the movie, a mysterious group called “12 Monkeys” released the virus which killed over 7 million people and brought humanity to its downfall. The same plot premise is in the show as time traveler Cole (Aaron Stanford) uses an experimental time-traveling device to come back to the present and assist Dr. Cassandra Railly (Amanda Schull) in stopping the virus.

The cast does a great job, especially Amanda Schull, and really brings out the darkness of events that are about to come. This show is perfect for viewers who like disaster like shows combined with time travel – 12 Monkeys has it both.

6. DC Legends of Tomorrow [2016-2022]

Superhero TV shows have all the rage nowadays so it’s just fair to put one that’s about time travel on this list as well. DC’s Legends of Tomorrow might not have the most interesting story but boy, they are fun to watch. Most of the episodes are stand-alone and you can simply sit on your sofa, watch one and continue after a month without worrying about missing the parts of the plot. When it comes to the story, basically, a team of superheroes travels back in time to prevent bad things from altering the timeline, thus saving the future.

DC’s Legends of Tomorrow is a part of the Arrowverse so the show crosses over with Arrow, The Flash, and Supergirl several times. The main reason why this show is on our list is the fact that it’s relaxing to watch, witty, and overall entertaining. Caity Lotz, Amy Louis Pemberton, and Dominic Purcell are just some of the names that star in this show – the cast is full of superstars well-known to superhero fans.

5. Manifest [2018-2023]

The show was canceled after three seasons and picked up and renewed by Netflix for the fourth and final season. Manifest tells a story about Flight 828 which vanished into thin air and reappeared five and half years later. The problem is that the passengers have no idea what happened since from their perspective, they just went through a troublesome storm but landed on time, as planned. As they rejoin society, numerous problems arise, especially when some passengers start getting visions (“ Callings “) of future events.

The show has a strong “Leftovers” vibe to it, exploring the topic of how humans are unable to cope with things that they can’t explain. Melissa Roxburgh (Michaela Stone) and John Dallas (Ben Stone) are the stars of the show and have received numerous praises for their performance in Manifest. This TV series is about time travel but also offers a lot more and tells a mysterious story that you will surely enjoy.

4. Dark [2017-2020]

Dark is the first Netflix German series. The show itself is difficult to place as it combines several genres, including sci-fiction, horror, mystery, drama, and thriller. While this combo might not work for some other shows, Dark is an exception – the show delivers magnificently although one might argue that it’s a slow-burn in the beginning. Dark is one of the shows like Black Mirror in a suspenseful feeling that you get while watching it.

Dark starts in Winden, a small fictional German town in 2019. Children begin to disappear from the town so an investigation led by four families takes place. Throughout the three seasons of Dark, the truth will include multiple timelines, wormholes, conspiracies, and parallel worlds. We won’t say any more since the whole point of the show is for the viewer to try to understand the events that took place (and when the events took place). The German cast is lead by Louis Hofmann, Karoline Eichhorn, and Lisa Vicari. This time-travel TV series received praise from both the audience and the critics and is a must-watch. 

3. Fringe [2008-2013]

When it comes to TV shows about time travel, supernatural phenomena, parallel worlds, and doomsday events, Fringe is a must-see masterpiece. First of all, the show has that 2000’s vibe to it which is sure to evoke memories from older viewers. Fringe is well-written and humorous and even a non-fiction fan will be able to enjoy it.

The cast is just astonishing: Anna Torv plays FBI Agent Olivia Dunham who leads Fringe Division. This division is kinda similar to “unsolved cases” that Molder and Scully used to investigate in X-files, although without (that many) aliens. Dr. Walter Bishop (John Noble) and his son Peter (Joshua Jackson) assist her in solving these cases. The show has many episodes that are stand-alone type but in the end, it wraps up nicely and tells a compelling story about father and son love filled with sci-fi elements.

2. Travellers [2016-2018]

Travelers have a unique story that widely differs from similar TV shows about time travel and that’s one of the reasons why it’s so high on our list. The basic premise of the show is that the future is ruined and people from it ( Travelers ) transfer their conciseness into humans that are about to die in the 21st century in order to alternate the timeline, following orders from an AI called “Director”. Sounds wild, right? Well, it works pretty well –  Travelers are super fun and the characters are well-written and very diverse.

The cast is brilliant and is led by Eric McCormack (Grant MacLaren) and MacKenzie Porter (Marcy Warton). Another thing that puts this show at the top of our list is the fact that the sudden ending of season 3 really leaves a massive impact on a viewer. We must admit that a decision from Netflix to cancel Travelers after three seasons is baffling. Be it as it may, we are sure that you will enjoy this story and the ending will leave you breathless.

1. Doctor Who [1963-1989; 2005-present]

When a TV show has an actual Guinness record category of longest-running science fiction series, it is hard not to put it in the first place in our list. Doctor Who is a british sci-fi TV show about time travel and numerous other fictional motives and it has been on BBC since 1963. The show follows the adventures of a Time Lord ( The Doctor ), a being that appears to be human but explores the universe, combats foes and helps people in need using his time-traveling ship ( TARDIS ).

Since Doctor Who had over 850 episodes so far, we won’t try to dig into the plot too much – it would require multiple articles just to cover it. The show gained so much popularity that it is considered a part of British culture and the fans call themselves “Whovians”. We highly recommend that you give this show a try (or a rewatch) since Doctor Who is a classic among TV shows about time travel.

Where Does the Concept of Time Travel Come From?

Time; he's waiting in the wings.

The dream of traveling through time is both ancient and universal. But where did humanity's fascination with time travel begin, and why is the idea so appealing?

The concept of time travel — moving through time the way we move through three-dimensional space — may in fact be hardwired into our perception of time . Linguists have recognized that we are essentially incapable of talking about temporal matters without referencing spatial ones. "In language — any language — no two domains are more intimately linked than space and time," wrote Israeli linguist Guy Deutscher in his 2005 book "The Unfolding of Language." "Even if we are not always aware of it, we invariably speak of time in terms of space, and this reflects the fact that we think of time in terms of space."

Deutscher reminds us that when we plan to meet a friend "around" lunchtime, we are using a metaphor, since lunchtime doesn't have any physical sides. He similarly points out that time can not literally be "long" or "short" like a stick, nor "pass" like a train, or even go "forward" or "backward" any more than it goes sideways, diagonal or down.

Perhaps because of this connection between space and time, the possibility that time can be experienced in different ways and traveled through has surprisingly early roots. One of the first known examples of time travel appears in the Mahabharata, an ancient Sanskrit epic poem compiled around 400 B.C., Lisa Yaszek, a professor of science fiction studies at the Georgia Institute of Technology in Atlanta, told Live Science 

In the Mahabharata is a story about King Kakudmi, who lived millions of years ago and sought a suitable husband for his beautiful and accomplished daughter, Revati. The two travel to the home of the creator god Brahma to ask for advice. But while in Brahma's plane of existence, they must wait as the god listens to a 20-minute song, after which Brahma explains that time moves differently in the heavens than on Earth. It turned out that "27 chatur-yugas" had passed, or more than 116 million years, according to an online summary , and so everyone Kakudmi and Revati had ever known, including family members and potential suitors, was dead. After this shock, the story closes on a somewhat happy ending in that Revati is betrothed to Balarama, twin brother of the deity Krishna. 

Time is fleeting

To Yaszek, the tale provides an example of what we now call time dilation , in which different observers measure different lengths of time based on their relative frames of reference, a part of Einstein's theory of relativity.

Such time-slip stories are widespread throughout the world, Yaszek said, citing a Middle Eastern tale from the first century BCE about a Jewish miracle worker who sleeps beneath a newly-planted carob tree and wakes up 70 years later to find it has now matured and borne fruit (carob trees are notorious for how long they take to produce their first harvest). Another instance can be found in an eighth-century Japanese fable about a fisherman named Urashima Tarō who travels to an undersea palace and falls in love with a princess. Tarō finds that, when he returns home, 100 years have passed, according to a translation of the tale published online by the University of South Florida . 

In the early-modern era of the 1700 and 1800s, the sleep-story version of time travel grew more popular, Yaszek said. Examples include the classic tale of Rip Van Winkle, as well as books like Edward Belamy's utopian 1888 novel "Looking Backwards," in which a man wakes up in the year 2000, and the H.G. Wells 1899 novel "The Sleeper Awakes," about a man who slumbers for centuries and wakes to a completely transformed London. 

Related: Science Fiction or Fact: Is Time Travel Possible ?

In other stories from this period, people also start to be able to move backward in time. In Mark Twain’s 1889 satire "A Connecticut Yankee in King Arthur's Court," a blow to the head propels an engineer back to the reign of the legendary British monarch. Objects that can send someone through time begin to appear as well, mainly clocks, such as in Edward Page Mitchell's 1881 story "The Clock that Went Backwards" or Lewis Carrol's 1889 children's fantasy "Sylvie and Bruno," where the characters possess a watch that is a type of time machine . 

The explosion of such stories during this era might come from the fact that people were "beginning to standardize time, and orient themselves to clocks more frequently," Yaszek said. 

Time after time

Wells provided one of the most enduring time-travel plots in his 1895 novella "The Time Machine," which included the innovation of a craft that can move forward and backward through long spans of time. "This is when we’re getting steam engines and trains and the first automobiles," Yaszek said. "I think it’s no surprise that Wells suddenly thinks: 'Hey, maybe we can use a vehicle to travel through time.'"

Because it is such a rich visual icon, many beloved time-travel stories written after this have included a striking time machine, Yaszek said, referencing The Doctor's blue police box — the TARDIS — in the long-running BBC series "Doctor Who," and "Back to the Future"'s silver luxury speedster, the DeLorean . 

More recently, time travel has been used to examine our relationship with the past, Yaszek said, in particular in pieces written by women and people of color. Octavia Butler's 1979 novel "Kindred" about a modern woman who visits her pre-Civil-War ancestors is "a marvelous story that really asks us to rethink black and white relations through history," she said. And a contemporary web series called " Send Me " involves an African-American psychic who can guide people back to antebellum times and witness slavery. 

"I'm really excited about stories like that," Yaszek said. "They help us re-see history from new perspectives."

Time travel has found a home in a wide variety of genres and media, including comedies such as "Groundhog Day" and "Bill and Ted's Excellent Adventure" as well as video games like Nintendo's "The Legend of Zelda: Majora's Mask" and the indie game "Braid." 

Yaszek suggested that this malleability and ubiquity speaks to time travel tales' ability to offer an escape from our normal reality. "They let us imagine that we can break free from the grip of linear time," she said. "And somehow get a new perspective on the human experience, either our own or humanity as a whole, and I think that feels so exciting to us." 

That modern people are often drawn to time-machine stories in particular might reflect the fact that we live in a technological world, she added. Yet time travel's appeal certainly has deeper roots, interwoven into the very fabric of our language and appearing in some of our earliest imaginings. 

"I think it's a way to make sense of the otherwise intangible and inexplicable, because it's hard to grasp time," Yaszek said. "But this is one of the final frontiers, the frontier of time, of life and death. And we're all moving forward, we're all traveling through time."

Time Travel Equation Solved By Astrophysicist

Posted: March 25, 2024 | Last updated: March 25, 2024

After a lifetime of pursuing the idea, Physics Professor Ronald Mallett at the University of Connecticut has potentially figured out the theoretical aspects of time travel. Professor Mallett believes that black holes, rotating light, and gravitational pulls may hold the key to exploring time, but it’s all theoretical for now. There are still a lot of hurdles and limitations to handle before time travel can have real, practical applications.

A Life Spent Thinking About Time Travel

Love and loss pushed Professor Mallett into an obsession with time and space. When he was 10 years old, his father passed away from a heart attack. It was his father who nourished his love of science, but H.G. Wells’ book The Time Machine pushed him towards a focus on time travel.

He was hooked from the very first paragraph of the book, “Scientific people know very well that Time is only a kind of Space. And why cannot we move in Time as we move about in the other dimensions of Space?”

That paragraph never left him, and the professor let that time travel question guide him through school and into the Professor Emeritus of Physics position at the University of Connecticut.

Einstein And Black Holes

As he grew up, Professor Mallett spent much of his time on Albert Einstein’s theories about black holes. While his interest in time travel only continued to grow, a potential solution never showed itself. At least, not until the professor ended up in a hospital with a heart condition.

There, lying in the hospital bed, inspiration hit him. Black holes and the gravitational fields they created were the answer to time travel. These gravitational fields had the potential to lead to time loops, which then theoretically could allow people and objects to travel back in time.

Black Holes Manipulating Gravity

While this idea offered an ability to manipulate time, the other problem was how to use these time loops for time travel.

Professor Mallett found this time travel solution much easier than the first problem. Strong and continuous beams of light, like a ring of lasers, with a particular rotation could be used to manipulate gravity and mimic the distorting effects of a black hole.

Though the details are rather complicated, the big time travel picture is a lot simpler to grasp. The professor offers a comparison to help people understand. “Let’s say you have a cup of coffee in front of you. Start stirring the coffee with the spoon. It started to spin, right? That’s what a spinning black hole does. In Einstein’s theory, space and time are related to each other. That’s why it’s called space-time. So when the black hole spins, it will actually cause time to shift.”

Much To Figure Out

Professor Mallett may now have a theory on time travel and a machine to use to make it possible, but that doesn’t mean it will be here in the next few decades.

There’s still a lot to figure out to make such travel practical, such as where the insane amount of energy such a machine would require could come from, and how big the machine would need to be.

There’s also a major constraint on the machine. According to his theories, time travel would only be possible to the very beginning of when the machine was first built. In this way, it’s more like a one-way message service. You can potentially go forward quite a distance, but going back in time is limited by the machine’s creation.

Theoretical Aspects Of Time Travel

The professor has made a huge leap in figuring out the theoretical aspects of time travel, but there’s a lot more to discover and quite a few hurdles and paradoxes to figure out before scientists practically start messing around in time.

Still, the theory is a step in the right direction and does suggest that people can push past what science currently considers possible.

The Time Dilation Experiment: How Physicists Prove Its Real

As a team of physicists, we are fascinated by the concept of time dilation. It is a fundamental aspect of Einstein's Theory of Relativity that describes how time can appear to pass differently for two observers in different frames of reference. This theory has been proven experimentally time and time again, and today we want to take you through some of the most compelling experiments that have been conducted to demonstrate this phenomenon.

The first thing we need to understand is what time dilation actually means. In simple terms, it refers to the fact that time appears to move slower for an observer who is moving relative to another observer who is stationary. This may sound counterintuitive, but it has been demonstrated repeatedly through carefully designed experiments. These experiments not only help us better understand the nature of our universe but also have practical implications in fields such as GPS technology and space travel. So let's dive into the exciting world of physics and explore some fascinating examples of how physicists prove that time dilation is real!

Understanding Time Dilation Theory

[the concept of time dilation experiment, the first time dilation experiment, recent time dilation experiments, atomic clock experiment, gravitational time dilation experiment, results and analysis, implications of time dilation, applications in space travel, theoretical implications, future research and development, frequently asked questions, how does time dilation theory relate to einstein's theory of relativity, are there any potential drawbacks or limitations to performing time dilation experiments, how do physicists account for the effects of time dilation in practical applications, such as gps systems, can time dilation be observed in everyday life, or is it only detectable in extreme conditions, what are some current areas of research or future applications for time dilation theory.

Understanding the mind-bending theory of time dilation is essential for grasping the intricacies of Einstein's theory of relativity. In simple terms, time dilation can be defined as the difference in elapsed time between two events that occur at different distances from a gravitational mass or relative to each other's motion. This means that time passes slower for an object in motion or near a massive object than it does for an observer who is stationary and far away.

To understand this concept better, let's take an example. Imagine two synchronized clocks placed at different altitudes - one on top of Mount Everest and another at sea level. According to the theory of general relativity, because gravity is weaker at higher altitudes, the clock on Mount Everest would tick faster than the one at sea level. This phenomenon can be explained mathematically using equations such as Lorentz transformations and special relativity formulas.

With this understanding of time dilation, we can now delve into the concept of time dilation experiment without missing any crucial details.

](/blog/time-travel-theories/time-dilation/time-dilation-experiment-physicists-prove-real)As we delve deeper into the concept of measuring time in different ways, a mind-bending realization starts to take shape. The theory of relativity suggests that time is not constant and can be influenced by various factors, such as gravity and motion. To prove this theory, physicists have conducted numerous experiments over the years using advanced measurement techniques and observational evidence.

To further illustrate the concept of time dilation, here are some key points to consider:

• According to the theory of relativity, time passes more slowly in strong gravitational fields or at high velocities.
• This means that if two individuals were traveling at different speeds or in different gravitational fields, they would experience time differently.
• The first experimental evidence for time dilation came from the famous Hafele-Keating experiment in 1971, which involved atomic clocks being flown around the world on commercial airliners.

With these ideas in mind, let us explore how physicists were able to conduct their first time dilation experiment.

You will delve into the first demonstration of time's non-constant nature through an experiment using advanced measurement techniques and observational evidence. The first time dilation experiment was conducted by two physicists, Joseph Hafele and Richard Keating, in 1971. They flew atomic clocks on separate commercial airplanes that traveled around the world in opposite directions. This experimental setup allowed them to compare the elapsed time of one clock with respect to another.

The data collection process involved comparing the readings of the clocks after they returned from their journeys. The results showed that the clock traveling westward experienced a slower passage of time than the stationary clock on Earth, whereas the clock flying eastward experienced a faster passage of time than its counterpart on Earth. This finding provided strong evidence for Einstein's theory of relativity and proved that time dilation is not just a theoretical concept but a real phenomenon that occurs in our universe.

This groundbreaking experiment paved the way for further research into understanding how gravity affects space-time and led to more recent time dilation experiments exploring new frontiers such as black holes and neutron stars.

In recent years, there have been several groundbreaking experiments that further prove the existence of time dilation. One such experiment involved atomic clocks, which are incredibly precise timekeeping devices. By measuring the differences in time between two identical atomic clocks (one stationary and one in motion), scientists were able to observe time dilation effects predicted by Einstein's theory of relativity.

Another experiment involved observing gravitational time dilation, which occurs when an object is located near a massive body causing it to experience slower time than an observer farther away from the massive body. Scientists observed this effect by using extremely sensitive atomic clocks placed at different heights above sea level.

The results and analysis of these experiments provide even more evidence for the reality of time dilation and its importance in our understanding of physics.

You'll feel the ticking of an atomic clock in your bones as you imagine the precision and accuracy required for this experiment. Atomic clocks are the standard for measuring time with extreme accuracy, relying on the natural vibrations of cesium atoms to keep incredibly precise time. The recent atomic clock experiment conducted by physicists tested whether or not time dilation occurs at different altitudes above Earth's surface.

The test involved comparing two identical atomic clocks: one kept on the ground and another taken up to a high altitude via airplane. The results confirmed that time dilation does indeed occur, with the higher altitude clock running slightly faster than its grounded counterpart due to gravitational differences. This level of atomic clock accuracy is essential for measuring even the smallest differences in time dilation, providing crucial data for theories like Einstein's theory of relativity.

Now, let's move on to the next step where we explore how physicists conduct experiments that prove gravitational time dilation is real.

Get ready to feel the thrill of discovery as we delve into the fascinating world of gravitational time differences and how they can be measured with incredible precision. The gravitational time dilation experiment involves measuring the difference in time between two clocks placed at different altitudes in a gravitational field. As Einstein's theory of general relativity predicted, time moves slower closer to a massive object due to the curvature of space-time caused by gravity.

Experimental evidence for this effect was first observed in 1962 when atomic clocks on board airplanes flew around the Earth and were found to be out of sync with identical clocks on the ground. More recent experiments have used highly precise atomic clocks flown on airplanes or launched into space satellites to measure these effects even more accurately. These experiments have also been able to detect other factors that can affect time dilation, such as changes in velocity and gravitational waves. With this technology, physicists are able to confirm that general relativity is indeed an accurate description of our universe.

As we move onto discussing results and analysis, it's important to note that these experiments have not only provided evidence for Einstein's theory but also opened up new avenues for research into fundamental physics, including investigations into dark matter and quantum gravity.

Now we can finally see the fascinating and groundbreaking results that confirm Einstein's theory of general relativity. The gravitational time dilation experiment has provided evidence that time slows down in stronger gravitational fields, which is consistent with the predictions made by the theory. By using precision measurement techniques to compare atomic clocks at different altitudes, scientists have demonstrated that time passes more slowly closer to massive objects.

The results obtained from this experiment are statistically significant and provide strong support for Einstein's theory. They indicate that gravity affects not only space but also time, which is a fundamental concept in physics. These findings have important implications for our understanding of the universe and its behavior. As we move on to discussing the implications of time dilation, we must keep in mind how crucial these experimental results are for advancing our knowledge of physics.

So now that we understand the basics of time dilation and how it has been experimentally proven, let's look at some of its implications. First, there are practical applications for space travel: as objects near the speed of light experience less time than those at rest, astronauts on long space missions could age slower than their counterparts on Earth. Secondly, time dilation has theoretical implications for our understanding of the nature of time itself and its relationship to space. Finally, continued research and development in this area could lead to new technologies and a deeper understanding of fundamental physics.

You'll be fascinated to learn that space travel could become more efficient and faster with the use of time dilation, as demonstrated by the fictional spacecraft in the movie Interstellar. The concept behind this is simple: if astronauts travel at a speed close to the speed of light, their time will slow down relative to those on Earth. This means that they can effectively age slower than their counterparts back home, allowing them to spend more time exploring and less time aging.

This has huge implications for astronaut travel, as it means that we can potentially send humans on long-duration missions without worrying about the effects of prolonged exposure to zero gravity. Furthermore, it also opens up possibilities for interstellar travel and even time travel (in theory). Of course, there are still many technical challenges that need to be overcome before we can realize these dreams, but it's an exciting prospect nonetheless. With all of this in mind, let's delve deeper into the theoretical implications of time dilation.

We can hardly contain our excitement as we explore the mind-boggling theoretical implications of time slowing down at high speeds. Philosophical considerations arise when we ponder how this phenomenon challenges our understanding of the nature of time itself. Our traditional view of time as an absolute and constant entity is shattered by the reality that it can warp and distort depending on relative motion.

The practical implications are equally fascinating. Time dilation has been observed in experiments involving atomic clocks, which have shown that even fractions of a second can make a significant difference over long distances or high velocities. This has important implications for GPS systems, where precise timing is critical for accurate location tracking. As we continue to unravel the mysteries of time dilation, future applications in fields such as space travel and telecommunications may become possible. But first, more research and development is needed to fully harness this incredible phenomenon.

You're about to discover the exciting possibilities that lie ahead in the field of researching and developing new technologies that can harness the incredible effects of time distortion at high speeds. With the confirmation of time dilation through experiments, scientists are now exploring ways to apply this phenomenon in innovative timekeeping devices and space travel. One potential application is using atomic clocks on spacecraft to accurately measure time in space, where the effects of gravity and velocity can distort time.

Technological advancements in quantum mechanics and nanotechnology are also paving the way for more precise measurements of time dilation. Researchers are experimenting with using quantum entanglement to create ultra-precise clocks that could be used for navigation or even detecting gravitational waves. As we continue to uncover more about this fascinating aspect of physics, it's clear that there are countless possibilities for future research and development in this field.

When discussing time dilation theory, it's impossible not to mention Einstein's contributions to the field of physics. His theory of relativity revolutionized our understanding of space and time, showing that they are intertwined and not absolute. Time perception is a crucial aspect of this theory, as it suggests that time can appear differently depending on one's frame of reference. This idea has been tested and proven in various experiments, including the famous Hafele-Keating experiment where atomic clocks were flown around the world to measure differences in elapsed time due to changes in velocity and gravity. Overall, Einstein's work on relativity paved the way for further exploration into the nature of time and how it relates to our physical universe.

When it comes to performing time dilation experiments, there are certainly limitations and potential drawbacks to consider. One major limitation is the accuracy of the experiment itself. In order to measure time dilation accurately, physicists must use incredibly precise instruments and methods. Even small errors in measurement could lead to inaccurate results, which could have serious implications for our understanding of the universe. Another potential drawback is that time dilation experiments can be incredibly complex and difficult to carry out. They require a great deal of planning, resources, and expertise, which may not always be available. Despite these challenges, however, time dilation experiments remain an important tool for physicists seeking to better understand the nature of time and space.

When it comes to practical implications of time dilation, physicists have developed experimental methods that help account for its effects. For instance, GPS systems rely on precise timing to determine a user's location. However, the satellites that send signals to GPS devices are in motion relative to the Earth and therefore experience time dilation. To ensure accurate timing, scientists must adjust the clocks on the satellites based on calculations of their velocity and altitude. By doing so, they can correct for the effects of time dilation and provide users with reliable location data. Overall, while time dilation can pose challenges in certain applications, physicists have found ways to mitigate its impact through careful experimentation and analysis.

Everyday examples of time dilation can be observed in our daily lives. One example is the aging process, where time appears to pass more quickly for those who are moving at higher speeds relative to a stationary observer. Experimental methods have also been used to prove the existence of time dilation, such as high-speed particle accelerators and spacecraft traveling at high velocities. These experiments have shown that time dilation is not just a theoretical concept, but a real phenomenon that occurs in extreme conditions as well as everyday situations.

Future implications of time dilation theory are vast and exciting. Technological advancements in the field will allow for more precise measurements, leading to a deeper understanding of the universe's fundamental workings. To put this into perspective, consider that the world's most accurate atomic clock loses only one second every 15 billion years due to time dilation effects. This level of precision is necessary for research in areas such as space exploration, satellite communication, and GPS technology. As we continue to push the limits of our understanding of time and space, time dilation theory will undoubtedly play a crucial role in shaping our future discoveries and innovations.

So, there you have it – time dilation is not just a theory, but a proven fact. Through various experiments conducted over the years, physicists have demonstrated that time really does slow down when an object moves at high speeds or experiences intense gravitational forces.

But what does this mean for us? Well, it has implications for everything from our GPS systems (which rely on precise timing) to our understanding of the universe itself. It's mind-boggling to think about how much we've learned through these experiments and how much more we still have yet to discover. The possibilities are endless and truly exciting.

In conclusion, time dilation is one of those concepts that can seem too abstract and outlandish to be believed at first glance. But thanks to the hard work and ingenuity of countless scientists over the years, we now know that it's real – a verified phenomenon that shapes our world in ways we're only beginning to understand. It's proof that sometimes even the wildest theories can turn out to be true – a testament to human curiosity and perseverance if ever there was one.

Fun experiments in a friend’s garage fueled this Tar Heel’s passion for engineering

By Jessica Abel

Recent graduate Kohen Goble balanced a major in chemistry, a minor in applied sciences and engineering and two undergraduate research assistant positions while at Carolina.

When Kohen Goble was in high school, he and his buddies would meet in a friend’s garage and conduct experiments on a variety of things, including capsaicin, a molecule found in chili peppers and responsible for the fiery sensation you get when you eat spicy foods. Their tools were rudimentary—glassware, fresh chili peppers, some ethanol—but their enthusiasm rivaled that of scientists on the verge of a big discovery.

“Our mixture got so concentrated in the oil that when we uncapped the vial, it hurt just to be in the room with it because it was so spicy,” said Goble, who recently graduated with a UNC bachelor’s degree in chemistry and a  minor in applied sciences and engineering . “It was fun and exciting to make up our own experiments and show them to our teacher.”

That first taste of materials engineering inspired a fascination with basic research on experiments they planned to conduct. “It sparked my curiosity in science at a fundamental level,” he said, “being able to see some of the things that we were learning in class.”

One of Goble’s favorite courses in the APS minor was taught by the late Zijie Yan, whom he called a mentor. In “Engineering Materials: Properties, Selection and Design” (APPL 462), he delved into the various physical, chemical and mechanical properties that differentiate classes of polymers, ceramics and metals.

“Leaving the class, I often thought deeper about the things I have taken for granted, such as the alloy in my kitchen knife’s blade or the economic-environmental balance to be considered when using one choice of adhesive over another,” he said.

In 2020, Goble enrolled at UNC-Chapel Hill and quickly immersed himself in the science, becoming an undergraduate research assistant in the  Brunk Lab , focusing his efforts on extrachromosomal DNA (ecDNA), which are molecules that exist independently from chromosomes within a cell’s nucleus. He investigated the role of ecDNA in various biological processes, including triple negative breast cancer, an especially aggressive cancer characterized by the absence of three hormone receptors: estrogen, progesterone and human epidermal growth factor 2.

He also was an undergraduate research assistant in the  Zhukhovitskiy group , making new building blocks called monomers from furan, a type of organic compound that has a ring structure made of four carbon atoms and one oxygen atom. These monomers are used to test a new kind of chemical reaction involving metals and commonly found in various natural and synthetic materials, including some plastics and pharmaceuticals.

As a technology intern at  Eastman , he worked in a lab that studies polymers, which are materials like plastics. Using the LabVIEW programming language, his main job was to improve a computer program that controls a special microscope to analyze polymer interactions.

“I analyzed different types of polymers to see how they looked and behaved when they were heated,” said Goble, who presented his research to the entire company. “I also learned how to use other machines to test the polymers’ properties, like how much they weigh when they burn.”

This fall, Goble starts a Ph.D. in material science and engineering at NC State but, in the meantime, he plans to stay at UNC through the summer to implement his honors thesis project, which involves the automation ecDNA image analysis across multiple different cancer cell lines using deep-learning methods.

“Ideally, I would love someday to either work at a small company startup,” said Goble, “or a corporation to be a group leader or run a lab.”
