Has there been only ONE Big Bang?
« on: 13/11/2015 13:29:14 »
  The Big Bang Theory as is stands now is that the universe, and all that it contains started out as one critically dense speck of energy(in essence an atom???), that at some point became unstable and exploded. Thus throwing everything it consist of out from this speck and for hundreds of billions of years spread to create what we know now as our current universe. One of the greatest questions within cosmology is whether this universe will continue to expand through Expansion, The Big Freeze, or result in The Big Crunch due to gravity.
  Now, if this theory is correct and we ultimately originated as a super condensed speck of energy, and before there was anything else, then where was this super condensed speck of energy located? It is safe to say that, "Something can't be nowhere?", correct? In saying so much, for us to start as a speck of energy, that speck of energy would have to have a place to call home, a position in, for lack of a better word, reality. But wouldn't this just contradict the idea that EVERYTHING comes from the Big Bang....
  With that being said, what about the idea of the Big Crunch. Now, this would seemingly make more sense, seeing this could quite easily give understanding to the idea that EVERYTHING that has a beginning, has an end. And give physics a reason to explain how the universe's seeming acceleration despite the laws of physics, especially seeing the universe's expansion at some point in the past seemed to slow down before it began to accelerate. Because how could this happen without another great blast of energy accelerating it. It would mean something is actually stretching the universe. Some unknown energy. We have come to call the ideal of this energy, Dark Energy. But this still doesn't explain how this form of energy goes against these laws of physics.
  Now these laws are called laws because they supposedly can't be broken. Otherwise, they would be called theories and not laws. ALL energy has to come from somewhere. And more importantly, CONSIST SOMEWHERE. So, I would suspect that maybe the speck of super condensed energy that destabilized, exploded and became our universe probably rested on this fabric of Dark Energy.
  Now, there are also theories of our universe resting on such a thing, with the possibility of being other supposed universe's upon this plane as well. What they tend to call extra dimensions. This even makes a little more sense in the fact that it gives an explanation that detracts the finite beginning of our universe and being. For this theory to be viable though, and to somehow give validity to the idea of a Big Bang, the idea of an forever expansion would not be possible. Otherwise, the universe's expansion would mean this Dark Energy fabric would also either be finite, or at the very least, cause these multiverses to at some point collide into each other.
  That is unless this fabric forever expands itself. But this would also contradict the laws of physics. The finite nature of it. That is, unless this fabric really is as a fabric, and can stretch and retract. And if that is the case, and everything follows the same laws, then it could be probable to say it would make sense that universe's would follow this same pattern; expanding and then retracting. And possibly within a continuous pattern like those laws of physics.
  Leading me back to my original question. Has there been only ONE Big Bang??? Because if there is a possibility of a Big Crunch to reverse the Big Bang, and seeing that speck of super condensed energy that resulted in the Big Bang and lead to our universe had to be a speck of energy SOMEWHERE, wouldn't it be safe to say there IS a possibility this big bang could be a continuous pattern as well? A pattern, a process that happens over and over? A process that has a finite existence of death and rebirth. A finite speed in which it happens. And ultimately even a credence to why we couldn't exceed that speed. Credence to the belief of some believer in the idea of a multiverse, that if we exceed that speed that it could cause us to, in essence jump to or see these other dimensions because we would actually jettison out of our own universe who can only contain its contents by moving faster than its contents. And with the right equipment, to be able to jettison off onto this fabric of Dark Energy until we reach or pass through another universe?

What do you think is the possibility of this ideal having some kind of possibility????

Our current model, suggesting that a singular Big Bang is most likely, has been widely accepted. And the physics involved with producing any other theory is very limited. In fact, it may be quite impossible for us to ever know whether other such Big Bangs have happened or will possibly ever happen again. On that score, it is highly likely that this topic will evolve into speculative conjecture. In that event, it may be safe to say that this thread belongs in the New Theories section.

This is not a particularly new theory - Einstein considered a cyclic universe to be a possibility (presumably, after he had dispensed with his "Cosmological Constant").

More recent researchers have also taken a cyclic model seriously, including models related to string theory.

The recent discoveries of Dark Energy (the accelerating expansion of the universe, restoring something like Einstein's Cosmological Constant) make it unlikely that the matter in our universe will clump together again.

Other theories relating to the Multiverse suggest that there may have been other Big Bangs, elsewhere in the Multiverse.

I appreciate you guys input. And it's not really meant to be a new, or otherwise, theory. It's mainly a question in reach of understanding. Seeing that I fail to understand the idea of an universe expanding and spreading throughout an apparent void of nothingness, as in retrospect the universe should be all that it is. You spill a glass of oil and the main portion of that oil spreads outward until it's contents(And all that is within!) are stretched too thin. And although from a perspective of particles within that oil, where all there seems there is is oil, the surface on which it's spreading is still there as well. With that being said, it would theoretically make sense for the universe to be spreading upon some type of surface as well. Correct?

Hi Jaye, welcome.  I have not read all of your OP yet, but one thing jumps out of it right at the start, probably because I had trouble with that sort of thing, and still get involved in convoluted discussions about "nothing" and "nowhere". :)

You have almost answered your own question. "Something can't be nowhere?" Agreed; but it can be everywhere.  If the Universe is all there is, it is everywhere, and always has been; even when it was a minuscule speck.

I understand your logic and your agree, something can be everywhere. I have kids to prove it! But what question remains is for something to fill up space there must be space to fill. Otherwise you're left with another chicken-and-egg paradox. You can't have a chicken without an egg and you can't have an egg without a chicken. This is what makes me think there is something out there beyond the universe.

Welcome Jaye.
All very interesting and philosophical questions. Ones like 'how can space expand into nothing' will keep us amused for eons.
Bill mentioned previous discussion and I managed to find it, you might want to have a look
