I recently read that there is apparently a repulsive force that acts over very long distances that is causing the expansion of the universe to accelerate. I was just wondering if there is any data that disprove the possibility that the big bang was not a singular event and that rather than being driven away by a repulsive force, the matter at the edge of the observable universe might not be getting drawn towards matter that is still farther away that had its origins in a preceding big bang. Is there some reason that we know this is not possible?
