what would happen to time in a black hole?

Answer 1

Time would stop.

Of course, it doesn't much matter - a black hole has such strong gravity that it separates atoms into subatomic particles, and subatomic particles into individual gluons, leptons, and quarks that are quashed into an infinitely-dense soup.

So, even if time didn't stop, there'd be no way to look at your watch.

Answer 2

Nobody really knows. Some scientists say that the singularity of the black hole is where all matter converges into fundamental particles. Other scientists say that black holes make such a deep rift in the fabric of space-time that it just goes on untill infinity. This could mean the intersection of dimentions, anything is possible. But untill we can put a space craft down into one, it will be impossible to know.

Answer 3

As you near a gravitational field, time slows. Because a black hole has infinite gravity, time (for you) would virtually draw to a stand still.

From your point of view - standing on a black hole - you'd see the whole universe age & die in just a few of your seconds... and, it'd be very, very bright - because all the energy of all the events that would happen in the normal universe would (for you) seem to fall in on you all at once.

Answer 4

Because of the gravitational time dilation, time would seem to get increasingly stretched out on approach to the event horizon, and to an outsider, a spaceship would seem to be falling towards the event horizon forever. From he point of view of the occupants of the spaceship, they would seem to be accelerating rapidly, and instantly hit the event horizon (and also get stretched out by the tidal effect). I think that all four space-time dimensions would become equivalent in a black hole, so talking about time in that context is meaningless.

Answer 5

Time for an astronaut approaching a black hole would for him appear to pass by normally. Another astronaut outside of it would see time for the first astronaut slowing down until it stops when he reaches the event horizon. There time as we know it stops. He would appear to be hovering there to a distant observer, but from the viewpoing of our doomed astronaut, he would be killed immediately. Time and space as we understand them do not exist inside black holes. At the event horizon, even Relativity breaks down and a new theory of quantum gravity is required. To my knowledge physicists are working on quantum gravity theories, but no clear, complete theory has emerged as of yet.

Answer 6

as to time inside a black whole no one know. but at the event horizon, ( point of no return) time will stop.
hope this helps

Answer 7

i agree with brian time would stop.
