Does time stand still in a black hole?
Kerr spacetime is time-independent, meaning that nothing in Kerr spacetime changes over time.
In effect, time stands still.
A black hole in such a state is essentially stationary.
Once mass, or even light, passes within the event horizon of a black hole, it cannot escape the black hole’s gravitational clutches..
What is inside a Blackhole?
The event horizon is where the escape speed exceeds the speed of light: you’d have to be going faster than light (which is impossible for any bit of matter) to escape the black hole’s gravity. Inside the event horizon is where physics goes crazy. … A singularity is what all the matter in a black hole gets crushed into.
Can a black hole kill you?
But that all changed in the early 1990s when different research teams in Canada and the US discovered a second singularity called a “mass inflation singularity.” It still has a strong gravitational pull, but it would only stretch you by a finite amount, and potentially NOT kill you in the process, meaning, you might …
Who has died in a black hole?
Stephen HawkingStephen Hawking, the prodigious British theoretical cosmologist who became an international celebrity, died at his home in Cambridge, U.K., early today, at the age of 76.
Could we be living in a black hole?
A black hole is an object so dense that not even light can escape it. … Some researchers believe the universe emerged from the collapse of a star in a very different reality with five dimensions, meaning our reality was created by a black hole which we could still be living inside.
What would you see if you fell into a black hole?
“First of all, you approach the speed of light as you fall into the black hole. … So if you’re able to look forward toward the black hole, you see every object that has fallen into it in the past. And then if you look backwards, you’ll be able to see everything that will ever fall into the black hole behind you.
How long does it take to fall into a black hole?
16 secondsThe time is in seconds if the black hole has a mass of 5 millions suns, approximately equal to the mass of the supermassive black hole at the center of our Galaxy. On your trajectory, it takes 16 seconds to fall from the horizon to the singularity.
What happens to time in a black hole?
Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow as it approaches the event horizon, taking an infinite time to reach it. … Typically this process happens very rapidly with an object disappearing from view within less than a second.
Can you survive inside a black hole?
Black holes are bizarre objects that get their name from the fact that nothing can escape their gravity, not even light. If you venture too close and cross the so-called event horizon, you’ll never escape. For small black holes, you’d never survive such a close approach anyway.
Does time exist in space?
Time is a complex subject for physicists. Einstein showed that time and space are intimately linked and that the progression of time is relative, not absolute. … Our science is thus based on the assumption that the laws of physics, and the passage of time, exist throughout the Universe.
What happens to time at the event horizon of a black hole?
The event horizon is what, in relativity parlance, is called a “lightlike surface”; light rays can remain there. For an ideal Schwarzschild hole (which I am considering in this paragraph) the horizon lasts forever, so the light can stay there without escaping.
