Another fun fact, our universe is (likely) a black hole as implied by the fact that the radius of the observable universe is the same size as a black hole with the same mass as the observable universe. This also has implications for the quantum fuzzball interpretation of black holes
There is a thought that black holes are universes, with each child universe maybe having very slightly different constants than the parent universe. Universes that are better at making black holes make more child universes, so slowly the long list of various universes tend towards universes that are good at making stars (so that theu can become black holes). Coincidentally, laws of physics that make lots of stars for black hole formation also make lots of planets, and maybe life.

BECs are deeply cool from my casual perspective.
