I have some questions about black holes?

Black hole theory violates several known laws, one of them being the law of gravity. Newton published his shell theorem showing that gravity in a solid sphere decreases to zero at the center. That is because all the mass is pulling away from the center, so the net effect is zero. So gravity can't build up the way the theory says it can. Another part of the theory is that electrons and protons can be squeezed together to make neutrons. No such thing has ever been observed. It is entirely made up. Third, a nucleus can only exist with certain combinations of protons and neutrons called islands of stability, and as the nuclei get larger the islands of stability get farther apart. If a collection is off by even one particle it flies apart instantly. So neutronium is impossible.

In Einstein's theory the gravitational field, manifest in the curvature of spacetime, is coupled to its sources by the field equations, the sources being described by an appropriate energy-momentum tensor, and so the Principle of Superposition does not apply. This means that one cannot simply pile up masses in any given spacetime because the field equations must be solved for each and every configuration of matter proposed.

For the final nail in the theory, it depends heavily on the gravitational constant being constant, which it is not. It varies in the third decimal.
