What is a black hole event horizon (and what happens there)?
The event horizon is the spherical outer boundary of a black hole loosely considered to be its "surface." It is the point, according to NASA, that the gravitational influence of the black hole ...
Why Time Slows Down Near a Black Hole: The Physics Explained
Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. ... and these signals are limited to travel at (or under) the speed of light. This is the basic idea behind ...
Event horizon
In astrophysics, an event horizon is a boundary beyond which events cannot affect an observer. Wolfgang Rindler coined the term in the 1950s.. In 1784, John Michell proposed that gravity can be strong enough in the vicinity of massive compact objects that even light cannot escape. At that time, the Newtonian theory of gravitation and the so-called corpuscular theory of light were dominant.
How is Time Changed Inside a Black Hole?
From your perspective, Sally appears to slow down as she approaches the black hole, and the time interval between her flashes of light gradually increases. Additionally, the light she sends back to you gradually gets dimmer and redder. According to your perspective, Sally never actually descends into the black hole; she will travel more and ...
Understanding Time Dilation at the Event Horizon
One of the basic issues here is that no external observer can ever see something fall across the event horizon. From an external perspective anything falling into the black hole 'freezes' at the horizon, trapped by an asymptotic slope of time dilation. Here's the problem, when we say 'external observer' that doesn't mean an astronaut or a ...
Event horizon
event horizon, boundary marking the limits of a black hole.At the event horizon, the escape velocity is equal to the speed of light.Since general relativity states that nothing can travel faster than the speed of light, nothing inside the event horizon can ever cross the boundary and escape beyond it, including light.Thus, nothing that enters a black hole can get out or can be observed from ...
What Are Wormholes, and Could They Be the Answer to Time Travel?
A singularity and an event horizon. All things that cross the event horizon will never escape back into the universe - things go in and never come out. Mathematically we can also define the polar opposite of a black hole, which is conveniently called a white hole. White holes also have a singularity, but their event horizons act differently.
Are black holes time machines? Yes, but there's a catch
Published: January 3, 2023 2:16pm EST. Black holes form natural time machines that allow travel to both the past and the future. But don't expect to be heading back to visit the dinosaurs any ...
Anatomy
The event horizon captures any light passing through it, and the distorted space-time around it causes light to be redirected through gravitational lensing. These two effects produce a dark zone that astronomers refer to as the event horizon shadow, which is roughly twice as big as the black hole's actual surface.
How the Event Horizon Telescope observes black holes
The Event Horizon Telescope. This image was enabled by Very Long Baseline Interferometry (VLBI).With this technique, radio telescopes around the world are combined into a single virtual telescope - the Event Horizon Telescope (EHT).This was necessary, because there are two ways to achieve the highest possible resolution: short wavelength or large telescope size.
How does time work beyond the cosmic event horizon?
The event horizon. The cosmic event horizon (EH) is the largest distance a galaxy can be at, and still emit a light signal that may reach us in a finite time. It is currently roughly 16 Glyr away, i.e. a bit farther than the Hubble horizon. We also regularly observe galaxies farther away than the EH, but we see them in the past (as we see ...
NASA's Webb Will Join Forces with the Event Horizon Telescope to Reveal
The Sgr A* research team plans to apply for more time with Webb in future years, to witness additional flaring events and build up a knowledge base, determining patterns from seemingly random flares. Knowledge gained from studying Sgr A* will then be applied to other black holes, to learn what is fundamental to their nature versus what makes ...
What Happens When Something Gets 'Too Close' to a Black Hole?
All in all, matter near a black hole can be spaghettified, super-heated, squeezed, pancaked, pulled apart, and swirled around all while time itself stretches in unusual ways. But once that matter falls all the way past the event horizon into the black hole, we don't yet know exactly what happens. This is one part of the story that remains a ...

What happens beyond an event horizon?
Outside light from the rest of the universe would be falling in towards the black hole faster and faster, from your perspective, and you would see all of the universe play out in front of you. This is a peculiarity of the warping of space and time from the black hole. The moment you cross the event horizon wouldn't appear to be anything special ...
Could a Human Enter a Black Hole to Study It
At the event horizon, the black hole's gravity is so powerful that no amount of mechanical force can overcome or counteract it. Even light, the fastest-moving thing in our universe, cannot escape - hence the term "black hole.". The radial size of the event horizon depends on the mass of the respective black hole and is key for a person to survive falling into one.
Practical time travel: time dilation above the event horizon
Arrange your $10^{10^{100}}M_\odot$ of matter into a rigid shell that is a bit bigger than the event horizon. You get a normal flat spacetime inside. And a black hole spacetime outside. And your time on the inside ticks at the same rate as on the shell which is the rate just outside the event horizon of that huge black hole spacetime.
The Untold Truth Of Event Horizon

Time travel on the event horizon. : r/cosmology
Um, maybe. Time dialation is caused by both speed and gravity. Someone more versed in the math may chime in, but my instinct is that this value would vary based on the size of the black hole (the size of the event horizon) and the speed of the orbit. If 10 years pass on Earth, then 5 years would be passed for who ever is inside that spaceship.
