"" Well this could only be true if the Big Bang did existed. But if everything started from one point, than wouldn't everything evolve into the same thing? Cause from one point in space, if it were to expand, then everything on the two ends of the point, would be symmetrical and so everything would end up being the same thing because it started from the same point. Understandable?? ""
Well, that's where quantum physics comes in, because as soon as particles get created, they all behave in chaotic ways.
During the first few hundred million years after the big bang, it is believed that the universe was an intense flurry of superheated particles. Many of these particles would follow quantum rules, which would mean the universe would form with a random distribution and when many particles randomly got dumped near each other they began creating gravity.
