Does time stop in a black hole?
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. Someone falling into a black hole, however, would not see time stop.
What is a white hole in space?
White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.
Does a black hole have infinite gravity?
A black hole has an infinite density; since its volume is zero, it is compressed to the very limit. So it also has infinite gravity, and sucks anything which is near it!
