Entirely speculative, but I'm wondering what other's thoughts are on this? Admittedly, I initially became interested in this after reading an origins story on Galactus , but eventually moved on to real world theories (I love theoretical physics, just wish I could do the equations -- me and my stupid right sided thinking lol )
Two of the theories I've seen state that the big bang was either the end result of entropy in the previous universe or, we're what came out the other side of a black hole.
We'll probably never entirely know. Good thing I care more about research than end results!
This is a variation of the question asked of Augustine - "What was God doing before he created the universe?" Any answer is going to be less than satisfying, since before there were dimensions there is no easily understood frame of reference. The file cabinet scene in "Men in Black" is as good a theory as many.
You're right that there are some ideas along that line. One is that the universe goes through regular cycles of expansion and contraction, Big Bang/Big Crunch/Big Bang again/etc.
Another thought involves fluctuating branes that might have merged at some point in such a way as to start a Big Bang, the result of which we see as the universe.
big bang was either the end result of entropy in the previous universe
Interesting to ponder ....so in other words the entire previous universe possibly collapsed onto itself and became super dense of compacted matter and energy which caused it to explode out (Big Bang) to form the universe again ???

That's the theory but it has me wondering: if the universe is in a constant state of blue shift, how can it collapse in on itself? Even if there was a big enough incident of red shift centralized to a certain area of the universe to cause the big bang we'd still see the distant left-overs from the previous one out there.
Unless it was some kind of bizarro universe where everything began spread out and moved closer together over billions of years.

I'm not so sure we'd necessarily see distant left-overs from a previous universe. Part of the reason is that if the entire universe collapses in on itself there'd be nothing left. No space. No light. No time. Essentially nothing would remain, except what ever exists in a so-called point of infinite density. Admittedly, I have a problem with what constitutes something being truly infinite though.
Regardless, if the universe reverted itself back to say the Planck Level (or even something even smaller), perhaps a certain set of modulations could merge that could cause a new universe to form if the conditions are just right. That could most likely be a hit or miss event. Probably more misses than hits, but all it would take is one hit to make it all happen again. In other words, the universe just vanishes completely at the Planck Level (or whatever) until certain conditions at that level come together just right that would result in another Big Bang with another new universe. But there are still all kinds of other possibilities as well.
Well if we throw in dark matter and dark energy, it might work as a big bounce. Otherwise, I doubt it's workable.

LOL!
