ive heard a theory about that. dont know how well accepted it was, but someone had the idea that since they were reversed, the big bang sent matter outwords and antimatter inwards into some kind of black hole. another theory someone came up with is that matter went one way and anti the other. if this is true, the galaxies that are moving away fastest are antimatter gallaxies. point is, no one really knows.

the more man learns, the more he realises, he really does not know anything.
