Well, I also believe that there was a big bang. But my big bang is slightly different from yours. I know what caused my big bang. I believe God spoke, and BANG! it happened...
That the universe was expanding at the time all the light reaching us now was emitted is fact.
Also the velocity of objects measured by it's red shift shows gives us a model made up of a huge number of timeframes, I'm not sure what the universe is doing now vis-a-vis expanding or contracting since we are receiving light emitted at least 8 billion years ago , for all we know it got eaten and is being eaten by Tiamat and has been and is being converted into humongous a dragon turd.
My own guess is that gravity will eventually pull it all back together, since the initial impulse caused a linear velocity and gravitation exerts a quadratic opposing force, and both are functions of time.
Btw you need to get an understanding of M-Theory since that seems about to revolutionize how we view the basic structure of the universe.
Athough you "bible is science" guys haven't given up on trying to surpress science, the genie is out of the bottle and isn't going back in.
One of the biggest problems in Cosmology is what you "creationists" call the 2nd Law of Thermodynamics. the problem is stated like this "when incoming and outgoing states are infinitely separated in time, they behave as free noninteracting states"
and has to do with an event horizon which a forever expanding universe would have to have, and the existence of an event horizon makes it impossible for the S-matrix to happen.
That ,btw, is another indication of a cyclical universe IMHO
