Question

If the big bang theory is correct, with all the space of an infinite universe, then the odds of another big bang happening is almost guaranteed. Could someone prove/disprove this?

Answer 1

If the universe is infinite, it has always been infinite. At the Big Bang, it was infinitely dense. Since then it has just been getting less dense as space has expanded. In the infinite case, you wouldn't have enough curvature for spacetime to form the hypersphere.
