They say that energy cannot be created or destroyed, only converted from one form to another, we are wasting our time studying the big bang I would say?? In addition to that "every action has an equal and opposite reaction" and we are worried that some day the big bang will reverse and become the "Big crunch" well according to our theories the big bang shouldnt have even happened... and even if it did,  the "big crunch" should have equally happened at the same time...??
