    I'm wondering if perhaps as the big bang forces all matter to fly outwards from the epicenter, if one day (albeit a long time away) the initial force of this explosion will dissipate and gravity will take over - causing all matter in the universe to stop flying from the epicenter of the big bang and begin a reverse journey back to the center, only to create another big bang.

    ... So basically a continuous expansion and collapsing of the universe forming a cycle of big bangs. The big bang is the death of one universe and the birth of another.

    I'm no science buff, just a little interested so don't go ripping my head off if I'm missing something already proved that counters this theory.

    Thanks,

    Rich.

    There is no epicenter.

    There are (very) speculative cyclic theories. See for instance Cycles of time by Roger Penrose or Endless Universe: Beyond the Big Bang by Steinhardt and Turok.

    Ye it 'could', but what 'will' happen we don't know.

    Do you mean the Big Bounce?

    Thanks for the replies all.

    Wow, I didn't know there actually was an existing theory so similar to my thoughts-from-bed theory xD

    Usually just laying in bed and thinking before drifting off to sleep. This "big bounce" is exactly what I mean O.o - Thanks for mentioning it!
