Re:Dark Matter; whatever.. (Score 1)

I am not a physicist (so please bear with me) but as I see this science always depends on throwing bones (If I am not rude) and trying to find which one hit the target (the target that is thought of). One theory I did not read till now is the following. The basic assumption for the Big Bang is that all matter from the bang that we see was only one matter entity before the bang. In essence we always talked about one bang when we talk about this expanding universe. So it always explained why the expansion is happening but it could not explain why the expansion is accelerating. Now think of parallel bangs in the universe at same or different times. Then the matter from one bang will eventually cross paths with the matter of a different bang or for that matter come nearer to each other so that a new gravitational force builds up between the particles. Ultimately there will be different dense matter entities after the matters from different bangs combine. Now I want to extend the theory further that these dense matter entities will again start banging resulting in repeated explosions and coalescences. The coalesced entities are smaller than the parent entities whose explosions supplied the matter for these entities. At some point in time these particles will reach a position where there is no scope of further coalescence of particles from different explosions and the universe balances itself. What happens after that should be further thought of?
