Interesting (long) article about the latest theories of black holes
and singularities.

Singularities in Space-Time Prove Hard to Kill
Black hole and Big Bang singularities break our best theory of
gravity. A trilogy of theorems hints that physicists must go to the
ends of space and time to find a fix.
At the singular point in a black hole, time seems to grind to a halt,
and predictions become impossible.
