Can a proton or netron be compressed? Why don't individual neutrons behave like mini-black holes? What about the nucleus of an moderate weight atom; how much empty space is there in the nucleus of an atom? A lot of articles refer to the gravitational pull within a black hole, but what about the strong force acting on the protons and neutrons within a black hole? What happens to the electrons in a black hole? Does matter converted into energy produce the same amount of gravity? Does matter converted into energy produce the same amount of strong force? If not, and the strong force is a key factor in keeping a black hole intact, will the conversion to energy cause the black hole to dissapate? Is there a limit as to how fast the matter within a black hole can spin? Is there a limit as to how much centrifugal reaction force is generated by this spin? Could a black hole explode if the spin produced near light speeds with very a small radius of the matter within it?
