You may like my silly theory (made with zero evidence) to bring back the Big Crunch Theory. Imagine that spacetime is a sphere, and the Big Bang happened at the "north pole" so to speak. All matter will eventually meet back together and recombine at the "south pole" after which a new Big Bang will happen. Absolutely zero evidence for my idea and it's probably impossible to prove anyway but it's fun to theorize.
