So as our universe is stretching outwards eventually its going to cause a rubber band effect and spring back(a theory) Wouldn't that cause a big bang or would it be moving back so slowly that it wouldn't cause one? Because a rubberband you streatch it it streatches fast at first but than it causes you to streatch it slowly but than it snaps back with more speed and makes a pop/bang sound aka:maybe the big bang. So it makes you think when it springs back it would be fast and cause a second big bang. Right?
