Ok I believe in the “Big Bang”. I also believe in the “Multiverse” theory. I believe black holes form between universes. Yes Wormholes. Therefore I believe that a very large Universe had so much stuff in it that it went through a “Big Crunch” that created the biggest BlackHole/ singularity that could possibly exist. Then likely tearing through the mesh into a tiny universe that got very big very quickly. I kind of imagine it all like a small aquarium that you continuously blow bubbles into. When you run out of space bubbles pop. But are replaced.
