I read an artical on Georges Lemaitre (1894-1966), a Belgian mathematician and Catholic priest who developed the theory of the Big Bang.

If the big bang only happend once this gives religious thinkers the ammunition to believe that God created the universe. But if the Big Bang happened over and over, expanding and collapsing then that means the universe has always been.

Question: Is there new information on wether there is sufficiant matter in the universe to reverse the expansion? Dark Matter? Black Holes? Of course this is like arguing over a snapshot in time over a process Eons in length but I'm still curious on what everyone thinks.

Thanks,
Kurt
