Sorry, I made a mistake in one of my questions, so here they are again: 1) Do the laws of physics apply at a black hole singularity, or do they break down? Do the fundamental forces of nature reunify at black hole singularities? 2) What do you suppose happens when a black hole explodes? Might another universe be created? In any case, what would happen to the singularity? 3) I read somewhere that Stephen Hawking no longer believes that the universe began at the big bang singularity. Instead he seems to think that the universe began as a regular, smooth point of spacetime expanding in an ordered state, becoming increasingly lumpier and disordered with time, and ending in a "big crunch" singularity. Anyone have any details on his theory?Thanks!
