Hello. I'm a layperson curious about physics. I've read that Quantum Gravity could eliminate the predicted singularity inside a black hole based on General Relativity. If that's true, what would happen from the frame of reference at the center of a black hole? Would that cause a tremendous amount of energy to be released as the star collapses? (Which, of course, would be contained within the event horizon.) I've read that a supernova can shine as bright as 10 billions stars. If there was an explosion at the center of a black hole, instead of a singularity, roughly how bright would it be? I'm also curious about degenerate matter. Could quark degeneracy (a quark star) or hypothesized preon degeneracy stop an imploding star within the event horizon?
