eternal recurence

[darkblight]

odd it was described in school as everything becoming compacted together then blowing up

over time wouldnt this central point of force pull matter back

There is no central point. The big bang happened/is happening everywhere at the same time as every point in the universe is expanding away from every other point in the universe.

Don't think of the big bang as if it were like a bomb exploding. The closest analogy I can come up with is asking you to pinpoint the centre of the surface of an expanding balloon or sphere. No point on that surface can claim to be the centre anymore than any other point. The same is true for the universe except with the addition of a third dimension.
