They are going in nearly opposite directions and are roughly a million miles apart from each other. Once you get a real idea of how empty space is (all of the not-to-scale diagrams you get in high school are no help here) it's harder to see how they could be related than not related.

True random distributions just work that way. If something that's supposed to happen once in a hundred years is spaced out at roughly 100-year intervals, that's not random.
