Alright so it seems the general consensus is that the big crunch theory is made possible by the effects of gravity slowing down the expansion of the universe and eventually reversing it. Unless I'm much mistaken this would require the entire mass of the universe to be evenly distrubuted at least on average over the entire area of the expanding sphere, because the vector of the combined gravitational forces would all have to point towards the center of the universe. Is this possible with the way matter has obviously clumped together (yes also by gravity) to form galaxies and what not?

There is not enough matter--and that includes dark matter--for the universe to be pulled back together. In fact, the universe is accelerating in it's expansion.
The Oscillating Universe Theory was done away with years ago in science.
Even if it were true, which is impossible, the Second Law would still apply and the universe we live in would now be in a state of heat death...and that clearly isn't the case.

Well you sort of answered your own question, arrr. The mass of the universe would have to be evenly distributed *on average*. However we don't know yet if this is the case or not. In fact, we don't know yet whether there is enough mass in the universe for a big crunch to happen. Its still one the unsolved questions of physics.

Scientists have now confirmed the universe is actually speeding up, so a Big Crunch is not possible. they feel everything will eventually speed away from each other and the universe will just die out.

Everything starts with a Big Bang, right? And the universe starts expanding. Eventually, when it's expanded as far as it can, there's a big crunch, right? And everything starts contracting.

I'm no cosmologist but I enjoy reading up on the latest theories. I believe that the nature of dark energy which is as of yet unproven/unknown may have a role to play in this. It may be better for you to ask this on in the science section of yahoo.
