Read an article in last months new scientist, a new theory is emerging in competition to Blackholes, called gravastars, the reason this theory has come about was because some people found a (pardon the pun) hole in the theory of blackholes.
Such holes I didn't have a chance to read through but these seem to be some good ones...because if light cannot escape a blackhole then the escape velocity would have to be actually faster than the speed of light, and falling towards the singularity your particles would reach tremendous speeds (I don't know what speeds you would acclerate too, but I would say they would be greater than the speed of light).
Also why does a singularity have to have infinite density with no volume, doesn't this seem absurd to others? With my incomprehensible and rough calculations you only need something with say the radius of a grapefruit and the mass of 180,000,000,000,000,000,000,000,000,000,000kg
This would mean the escape velocity would be greater that 300,000km/sec meaning light would not be able to escape.
But I guess it is a moot point as if it were this massive and such a great escape velocity then terminal velocity would be so great that atoms falling to the surface would break the universal speed limit of 300,000km/s.
