I think gravity is the inward force but what is the outward force that keeps it from collapsing to a singularity? (some theories say that the singularity does not exist) – Jus12 Jun 27 '12 at 14:23

The simple answer is in this wikipedia article:

A black hole is a region of spacetime where gravity prevents anything, including light, from escaping.1 The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole .

So it is gravity that causes the black hole's existence.

It needs college level courses to be able to work with the physics of the situation.
