Physicists Just Figured Out How Wormholes Could Enable Time Travel. Physics 16 July 2023. By Mike McRae. (gremlin/Getty Images) Theoretical physicists have a lot in common with lawyers. Both spend a lot of time looking for loopholes and inconsistencies in the rules that might be exploited somehow. Valeri P. Frolov and Andrei Zelnikov from the ...
What Are Wormholes, and Could They Be the Answer to Time Travel?
Wormholes also have the somewhat mystical ability to allow backwards time travel. If you take one end of the wormhole and accelerate it to a speed close to that of light, it will experience time dilation — its internal "clock" will run slower than the rest of the universe. That will cause the two ends of the wormhole to no longer be ...
Wormhole
A wormhole is a hypothetical structure connecting disparate points in spacetime, and is based on a special solution of the Einstein field equations. [ 1] A wormhole can be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are consistent with the general ...
What are wormholes? An astrophysicist explains these shortcuts through
Because wormholes represent shortcuts through space-time, they could even act like time machines. You might emerge from one end of a wormhole at a time earlier than when you entered its other end ...
Is time travel really possible? Here's what physics says
Relativity offers some options for backwards time travel, but this time they are much more theoretical. ... "Often wormholes are described as two black holes that have joined to each other," says ...
Can Time Travelers Reach the Past via Wormholes?
Well, yes, you can! You just never saw a game that extreme before. Time-travel research is like that. We're testing the laws of physics by looking at extreme conditions. There's nothing logically ...
Is Time Travel Possible?
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 ...
The Missing Piece: Are Wormholes the Key to Time Travel?
For decades, Scientists have pondered the conundrum of time travel -- debating whether or not it is even possible in our reality. However, research now points to the possibility of a wormhole, a ...
What are wormholes?
The wormhole theory postulates that a theoretical passage through space-time could create shortcuts for long journeys across the universe. Wormholes are predicted by the theory of general ...
What are wormholes?
Wormholes and time travel. In theory, a wormhole could also act as a time machine. Special relativity dictates that moving clocks run slowly. In other words, someone racing around at nearly the ...
The hunt for wormholes: How scientists look for space-time tunnels
In 2015 Italian researchers suggested there could be a wormhole lurking in the center of the Milky Way some 27,000 light-years away. Ordinarily, a wormhole would need some exotic matter to keep it ...
Wormhole Is Best Bet for Time Machine, Astrophysicist Says
However, Davis added, turning a wormhole into a time machine won't be easy. "It would take a Herculean effort to turn a wormhole into a time machine. It's going to be tough enough to pull off a ...
Time Travel Is Possible Through Wormholes—but You Can Only Ever Go
Time travel through a wormhole is technically feasible under the rules of theoretical physics—the only catch is that we can only ever go backward. In a blog post for Forbes, astrophysicist Ethan ...
Wormholes Explained: Taking a Shortcut Through Space and Time
Wormholes, like mass, warp the fabric of space-time. Also called an Einstein-Rosen bridge, a wormhole is a theoretical fold in space and time, creating an intersection of the fabric of space-time ...
FOLLOW-UP: What exactly is a 'wormhole'? Have wormholes been proven to
Stephen Hawking conjectured that while wormholes might be created, they cannot be used for time travel; even with exotic matter stabilizing the wormhole against its own instabilities, he argued ...
Travel through wormholes is possible, but slow
Travel through wormholes is possible, but slow. by American Institute of Physics. A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant ...
Scientists Calculate How to Time Travel Using Ring Wormholes
A recent study claims to have calculated a potential method of time travel. It involves a highly theoretical object called a "ring wormhole," which is a type of wormhole that connects two ...
What is a Wormhole and Will Wormhole Travel Ever be Possible?
In the film, a band of astronauts travel through a newly discovered wormhole connecting widely separated areas of space-time, in order to find a new world to call home. It sounds incredible, as if ...
Time travel
There are other scientific theories about time travel, including some weird physics that arise around wormholes, black holes and string theory. For the most part, though, time travel remains the ...
Wormhole Tunnels in Spacetime May Be Possible, New Research Suggests
After their prediction in 1935, research seemed to point toward no—wormholes appeared unlikely to be an element of reality. But new work offers hints of how they could arise, and the process may ...
Traversable wormholes are possible under certain gravity conditions
Wormholes can also act as time machines, so a viable wormhole solution would mean that time travel into the past is possible; that, of course, raises all sorts of difficult problems (like the so ...
Scientists may finally understand how wormholes can enable time travel
The prospect that wormholes could one day enable time travel isn't new. In fact, the use of wormholes to transport yourself across vast distances of space and time has been used in science ...
How long would it take to travel through a wormhole?
$\begingroup$ @John: The wormhole is not shortening any travel time--- you aren't going anywhere. It is the time between absorption and reemission in a black hole. I personally can't get the answer, and I know it is not in the literature, but we know how to calculate it in theory, and it is just my own failing that I don't know the answer today.
