The Big Bang Theory states there is no single point at which the universe was created. Since at the beginning of space and time there were heavily oscillating waves. The waves then began to expand after the Big Bang. That is why the theory states that since these waves expanded, the oscillation expands, therefore one heavily oscillatiing spatial point, now becomes expanding waves of space. Hense, the universe was created everywhere. At every point on that wave.

The problem is, if you were to circle the point of the oscillation, that is a specific point. As the waves grow, they outgrow the original boundary of the oscillation. But wouldn't that original point of heavy oscillation be some sort of relative point?
