Main Question or Discussion Point
Is gravity driving the exapansion of the universe? If so, would it be safe to assume that the universe is in fact in free fall towards a (hypothetical) larger "body" of mass? Trying to come to terms with what's actually driving the expansion is hard, but when I think about it, gravitational acceleration would be a possible answer to my un-educated mind. I can easilly come to terms with Einstein's universe, where the big bang starts off violent, but then slows down and eventually collapses in on it's self. But to comprehend that the universe is actually accelerating is hard for me to come to terms with unless I think of it in this way.
