i posted this in another thread, i want to see what you guys think about it. suppose for the sake of my theory that the big bang is correct and did occur. anyway, there's various theories about the end of the universe, and one is called the big crunch or something like that, i can't remember. that theory explains that since gravity attracts everything to everything else regardless of distance (which is true, it just has a neglible effect at extreme distances), eventually given enough time everything in the universe will be gravitationally pulled together. this is where my theory comes in. we know that the big bang was caused in some way by a singularity, the entire universe was compressed into one point. Well, given the above information, i think the universe would eventually compress down into a single point once again over a long time span. At some point, i think this new singularity would then once again 'exlode' and a new universe would be born. in that case, the universe might not be 14 billion years old, it could be any number you can think of. maybe hundreds of trillions, maybe 1 with 50 zero's after it. i think this theory actually makes pretty good sense, especially because when you think about it, "history repeats itself". Look at pretty much any trend in the universe and you'll see that things tend to go in cycles. perhaps our current universe is just one iteration of an endless cycle.
