We know that the universe is expanding at an accelerating rate. In big bounce (or oscillatory) models of the universe, why does the expansion of the universe end? And what drives the following, contracting phase?
Is it possible that dark energy could inverse its action at some point in the future, and effectively start pulling the universe together instead of stretching it apart? Or is some entirely different, "contracting" force involved?
