What happens to time inside of a black hole?

Question

How about mass?

Of course time exists. It is one of the dimensions used in membrane theory.

Answer 1

All wrong. Inside the event horizon, a rotation of the vector that describes spacetime position (x,y,z,it) takes place. The time element is no longer an imaginary quantity, but a space element of the vector does become imaginary. In effect, you are now free to move in any direction in the time and two space coordinates, but you must always move in one direction in the other space coordinate, just as outside the event horizon, we must always move towards the future. This restricted spatial direction inside the blackhole is towards the singularity; no matter what you do inside the event horizon, you will always move closer to the singularity. Time and space have effectively switched places in terms of how an observer can move within them.

This page says essentially the same thing in different words.

Mass does not change at all to the observer crossing the event horizon. To an outside observer, the mass falling in is always in free fall, so its mass does not change.

Answer 2

cbirch92 is close. Time is an interval between events, events require motion, and motion requires space. Inside a black hole matter is so densely packed that there is no room for motion, no motion, no time. A black hole can be bigger than a point, it is estimated that a black hole, three miles in diameter, exists at the centre of our galaxy. The mass of a black hole is tremendous, the event horizon is caused by the severe curvature of space around a black hole, anything that goes beyond this event horizon is lost to rest of the universe.

Answer 3

time exists, even if m-theory or super string theory are proved to be false. time is a part of the space time continuum, and through experiments involving time dilation and other things it has been proved to exit.

massive object has enough gravity and distort space, and by distorting space they are also distorting time. so since a black holes gravity is infinite (my theory is that it is not infinite, just very very close) time would some to a complete stop (or move very slowly if im right).

and mass is compressed into a very, very dense 0 dimensional point (again, i think its just very small, not a geometric point). thats why it has so much gravity. gravity is dependant on mass and density.

gravity is like a bowling ball on a trampoline. its going to make the trampoline sag. and if you take an object that weighs the same, but has a smaller volume, its going to make it sag more because all of the mass is focused on a smaller area.

ok goring, if theyve been proved not to exit then explain how we can almost directly observe them. we can see electromagnetic radiation from particles on the event horizon.

Answer 4

Time slows down to nearly a complete stop in a black hole...as percieved by someone outside of the black hole. Nothing happens to time as percieved by someone inside the black hole. If I'm in a black hole...I see time moving VERY fast outside of the black hole. If I were to ever escape the black hole (which by the way is not possible) the amount of time that has past outside of the black hole would be substantially larger then the amount of time, from my viewpoint, that I've been inside the black hole. Being alive inside a black hole would be like being alive for the remaining duration of the existance of the universe. The further you fall in (or collapse closer and closer to 0 mass) the faster time passes outside of the black hole. The life of the universe outside of the black hole would go by much faster for you inside.

Answer 5

nobody knows what happens to time inside a black hole. and by your assumption, time would only have to exist if brane theory is proved to be correct.

mass inside a black hole is theoretically predicted to be in a singularity at the center of the black hole. so a simple model would be, you have the event horizon, then a space with no mass, then a singularity, which contains all the masses its consumed.

Answer 6

In order to determine what happens inside a space black hole it is required to see and prove that a black hole as defined by Stephen Hawking Exists.
Recently Abhas Mitra proved in one of his papers that Black Holes by definition as they are presently understood violated the Basic tenets of Einstein's General Relativity.

Therefore it was concluded that a different entity existed and that Black holes do not exist in Nature.
Except in caves where there is no light.

Answer 7

Black holes distorts space and time. There is no escape from a black hole once beyond the event horizon.

Answer 8

"Time" may just be something that "man" made up. It may not exist in the larger universe. I heard once that "time" was invented to keep everything from happening at once!
