Then I thought of the contentions that I have read that the entire observable universe could be inside a black hole. Since the radius goes up with the mass, the average density of a hole with the universe's mass is rather close to the real average density of the universe... So this would have to depend then on the mass of the black hole, would it not? After all, a black hole containing our universe could be orbiting a black hole containing an anti-matter universe... If the black hole is small enough, then the mass/density ratio would not let subatomic "particles" exist anymore -- I don't know if that means it would be a squish of quarks or if even quarks would have ceased to be distinct -- and then the "matter"-ness or "antimatter"-ness of the contents would no longer be definable, since that is a characteristic of a higher level of particle than could exist in there. There must be some magic size point, though, when the mass is large enough that the average internal density allows "normal" particle formation inside. I have no idea what would determine what particles would form in this environment. Gee, this stuff is fun! Now, if I only knew what I was talking about... Regards, Will
