I have absolutely no idea how feasible all of this is, as my training was in languages and I didn't finish it, but hey.

If
a) the universe is expanding, then
b) all of the matter in the universe may be presumed to be moving away from a central point, and
c) gravity attracts all matter to all other matter, so
d) eventually the universe will stop expanding, and begin contracting, leading to all of the matter in the universe congregating in the centre, potentially forming a critical mass (or something) and therefore causing another Big Bang, therefore
e) this iteration of the universe may not be the first, and may in fact be the 54th.

I don't know whether this line of thinking is correct; can anybody help me out?

The big question is whether there is enough mass in the universe for it to stop expanding. If there is enough mass your idea (well, there has been people who thought it before you )may be possible. The currently known matter in the universe is not enough to stop the universe from expanding forever, but scientists are looking for dark matter which may be enough.
