what is the difference between the big bang and black hole singularity?

Question

at the instant of big bang there was a singularity very much similar to the one we find in black hole(or so i think).both of them have infinite densities and infinite space-time curvature and almost everything is infinite.except that the big bang is the begining of time and black holes the end of time..other than that what are the other differences??

Answer 1

Have you read the lates theories? Remeber they are suposed to be 2 kinds of black holes, Schwarzschild black hole is a non rotating black hole with a singularity and the Kerr hole, he say that a dying stars would collapse into a rotating ring of neutrons that would produce sufficient centrifugal force to prevent the formation of a singularity. Since the black hole would not have a singularity, Kerr believed it would be safe to enter it without being crushed by the infinite gravitational force at its center. If Kerr holes do exist, it might be possible to pass through them and exit out of a "white" hole. A white hole would have the reverse action of a black hole. So, instead of pulling everything into its gravitational force, it would use some sort of exotic matter with negative energy to push everything out and away from it. These white holes would be our way to enter other times or other worlds. So this must change your view as seeing Black hole as the finishing, maybe they can be a beginning to discover what the latest Hawkins theories talk about, Paralles Universe(2003).
And If I am not wrong, when the star dies and implode created a black hole whos event horizon absorved everything inside it, and it finish with the singularity and in this singularity all laws of physic doesn't exist meanwhile, right now we don't know how (Big Bang) this dense point was created it self, we know (theories) this point or singularity became so dense that it explode!
Well, hope you can understand better but this theme is so extense to discuss it here!
Bye!

Answer 2

Singularity is a mathematical concept. The Equations we use first proposed by Einstein to describe the nature does not behave well in some space or points. T = 0 is one such point. That is the time dimension. Which is usually nick named as Big Bang. Other singular points are space variables vs gravity. When gravity goes to infinity that is another singular point where our equations fail. This point is called black hole. There is no hole.

All other things you generally hear are wild imaginations of everyone.

Answer 3

The singularity at the center of a black hole is in the universe, it is part of it. The big bang singularity was not in the universe it was the universe and therefore cannot be said to be small or dense because there was nothing around it to make it dense nothing to compare it to. In theory the dimensions themselves were smaller and as a result everything within them was smaller.
