Question
Having to do with  infinite gravitational force.

Black holes have infinite gravitational force. Once entered separation and escape are not possible.

In the  big bang theory the singularity had infinite gravitational force where separation was possible.

Infinite gravitational force separation cannot happen, infinite gravitational force separation can happen?

Hello,

"Infinite gravitational force" is kind of a poor description of what's going on. Also, the new M-brane collision theory for the origin of the Big Bang kind of eliminates most discussions of "singularities" there that are analogous to those for black holes.


In regard to your reference to black holes, Kip Thorne's take on the issue is perhaps one of the more insightful (Ch. 5 'Warping Spacetime' in 'The Future of Theoretical Physics and Cosmology', Cambridge Univ. Pres, 2003). He notes:

"One might suspect it is the singularity's mass (or associated g-force) that warps the black hole's space. Not so, it turns out. The hole's space is warped by the enormous energy of its warpage. Warpage begets warpage in a *non-linear* self-bootstrapping manner that is a fundamental feature of Einstein's general relativity laws.

His diagrams (p. 78) are also excellent in explicating this, but alas, copyright laws prohibit reproduction of them to send you. I can only reference them.

A mor detailed and analytical discussion of "infinities" in a more mathematical context, based on an answer I'd given to another questioner, e.g.

May also provide some insights on this issue.
