I've been reading up a bit on black holes but I don't quite grasp why there should be a singularity at the center.
As far as I understand a singularity forms when all the mass of an object collapses to withing the schwarzschild radius, according to wikipedia http://en.wikipedia.org/wiki/Gravitational_collapse
"Within the event horizon, matter would have to be accelerated outwards faster than the speed of light in order to remain stable and avoid collapsing to the center. "
but as far as I know there's no upper limit to how fast something can accelerate is there?
So why assume that it collapses into a singularity instead of still having some kind of non infinite density?
