The Infinite Density of the Black Hole

I need a new idea for how humans live after age 15. And that's what's happening in general relativity. We think something else is going on, and we need a new theory to describe it. That infinite density also violates fundamental principles of quantum mechanics. It tells us we have an incredible amount of energy concentrated in a single point without any sort of quantum fuzz. But if we could look inside a black hole, we would get enormous clue about how space actually works,. What gravity really is, and how to unify general relativity and quantum mechanics.
