Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang. However, it’s plausible that what we see from inside our Universe is simply the result of being inside a black hole that formed from some parent Universe. If the black holes that form in our cosmos give birth to baby Universes, perhaps we arose from the formation of a black hole ourselves.
I find it unlikely that the laws of physics apply within a singularity, the place in which there exists more matter than is possible to exist in a single point. Plus, information/matter is effectively shredded and turned into particles by the black hole. There is no way for scientists to empirically prove what actually happens after entering the event horizon, so holding out for evidence is folly. Perhaps you could be more theoretical with your theoretical physics.
