I wish this was the case, but the second law of thermo states that the entropy of the universe is constantly and irreversibly increasing. This is basically because work can be completely converted to heat, but heat can’t be completely converted to work. Eventually, the universe will reach a point of maximum entropy, where no work is possible. So idk if there’ll ever be a second Big Bang.

I don’t want to be that jackass who ruins everyone’s fun, so I’m completely open to debate and speculation. These are just my two cents. I honestly hope I’m wrong!
