: : Black holes are phenomenal. They make up the matter of the universe. They bring about thousands of questions that only a few can be answered.... : : Do we really know what happens inside a black hole??

: : There isn't really an inside to a black hole, because it isn't really a hole, per se. It is a singularity of enormous, perhaps infinite density, : and it creates a gravitational sink. The observable edge of the gravitational sink is the event horizon, and it is true we cannot see beyond this. : Black holes certainly do not make up the matter of the Universe (thank goodness), but they may account for some of the dark matter. There are good : models of black holes, some of which are referenced on these messages...good luck!
