Logic and reason (the known laws of physics) say that if mass/energy is radiated out of a black hole, the energy/mass cannot simply 'disappear', but must GO SOMEWHERE.
FRiend, even the massive black hole at the center of the Milky Way is but a tiny and insignificant dust mote in the context of the Universe.
In order to create another universe, your black hole would have to magically produce more energy than exists... in the universe.
It simply does not compute; except maybe in the hollywoodesque Matrix of commie disinformation, which, in the old days, consisted of Big Foot, UFOs, little green men - and anything else that would shatter the mind of the Individual public.... and the Free Republic along with it.
