That is a great site Thatoneguy. Thanks.

Pertinent from it:

"Where in the universe did the Big Bang happen?

The Big Bang did not happen inside our universe, at least that's what our best understanding of physics seems to be telling us the last 70 years! I have tried to answer this particular cosmology question several ways in this Q/A archive. For some related answers you might want to have a look at my archive of questions about the Big Bang and the related expanding universe questions.

The fact of the matter is that we do not really understand how the universe came about. We cannot revisit that time so obviously any scientific descriptions we form have to be based on how the rest of the universe operates and our detailed understanding of the constitution of matter and the laws governing its interaction. The hardest features of the universe for us to intuitively understand are the relativistic theories which seem to govern how matter, energy and space-time operate under extreme conditions of temperature, density and energy.

The issues of where the Big Bang occurred and how it happened seems to be locked up in these unfamiliar and very subtle features of the physical world. It is impossible for a non-mathematician, using the best crafted english essays, to completely understand what it has taken decades of mathematical/logical abstraction and intense experimental analysis to create. Sorry!

The best, non-mathematical description that any cosmologist can create for describing the Big Bang is that it occurred in every cubic centimeter of space in the universe with no unique starting point. In fact, it was an event which our mathematics indicate, actually brought space and time into existence. It did not occur IN space at a particular location, because it created space ( and time itself) as it went along. There may have existed some state 'prior' to the Big Bang, but it is a state not described by its location in time or space. This state preceded the existence of time and space.

I know this sounds like science fiction, but in this case, the science came first, and the science fiction authors merely ran with this remarkable conception of 'the beginning' crafted by genuine physicists and astronomers, to create their new genre of stories."

1997 Dr. Sten Odenwald

-- The author states that the new quantum sciences tend to reject the "big Bang" theory for universal creation and also the theory that the universe is in decay. To prove that the universe is in decay, scientists would have to prove that protons decay, which they have not yet been able to do.

Found this in a website, doesn't explain much but read it toward the bottom where it says something about the big bang theory.

From several years of learning physics, I've of course also been trying to hypothesize the actual cause of the Universe coming into existence. I think that actually universes could be born at any given time at any given place. The thing is that such events are highly improbable and thus we have no knowledge of them. So what is then this cause. Suppose you have a matter-antimatter pair formation. All fine up to here, Heisenbergs uncertainty relationships predict that you can have extremely heavy pair formations on extremely short timescales, and so as to say "borrow" energy. Ok Up to this point, this is all very "normal". But now, these particles could just recombine to vacuum OR...... they could decay to other, lighter particles. Now, normally the decay routes for matter and antimatter should be the same but for some odd reason they are not, disturbing the normal recombination to vacuum. Now, what causes this breaking of what we call "symmetry". Good question, but even something as slight as another universe could have induced a slight anisotropy in space causing the decay routes to become unidentical. Currently this symmetry breaking can still be observed as there are several routes by which anti-matter can convert to "normal" matter, also explaining where all the antimatter went.

This is my version of "What happened", and I invite everyone to try and shoot holes into it and/or to educate me.

The Big Bang came from a singularity erupting. Think of a blackhole that reversed itself, spilling out all of its contents. The technicality of the matter is, was it an atom that erupted (the idea explored by an episode of Star Trek Voyager called the Omega Directive), or was it a singularity that erupted. There are quite a few problems with the Big Bang Theory, but a large portion of it is correct, just like evolution. Evolution happens to everything all the time, but it is a slow process. If evolution did not occur, you would look like everyone else in your species. The Big Bang is the reaction from an extremely dense object that basically boiled over. Think of a balloon that keeps become filled with air until it bursts, sending out a shockwave of sound and air. Well, the Big Bang sent out Radiation (energy) and either spilled out matter or formed matter from the shockwave. It is the one point in time where matter and energy were considered "created."

As far as the Big Bang being our explanation for something bigger that occured, you are also right. M-Theory is like a mix of holographic theory and superstring theory. It states that the universe is actually part of a larger whole (a greater universe). We cannot see outside of the universe, however (yet). Think of us as being part of a seed that is growing, but has not yet pierced its shell.

Other problems with the Big Bang are the idea that dimensions themselves, as well as time, were created by the Big Bang. Obviously the idea is a bit flawed. Certain particules that are suppose to be present have never been discovered. This causes M-Theory to seem more correct. Also, another theory has recently been presented to better explain the Big Bang. We are discovering the the Big Bang may not be a one time thing. Oh well, it doesn't really matter.

Ugh no...the Big Bang did not come from a Singularity.

Not the way you describe it anyways, please do not link "Black holes" to white holes, white holes do not exist, there are no such things.

Anyways...the idea of the Universe forming from a singularity is preposturous, as before the Big Bang there were no dimensions of space.

Therefore a universe could not have been created in any "place"...any time is debatable, but it could be assumed that there is no "time" either before the big bang.

So before the big bang there is literally nothing.

(Think of being born, your mother dying in child-birth, and you being raised by trees...finally at the age of 40 being alone with just trees and rocks and dirt, you ask yourself..."Where the hell did I come from?")

The best theory, but also the most confusing I've heard of, is the "Braine" theory...named after the man who came up with it.

I think it is in some way tied to string theory.

But he basically says that two "braines" a fabric of space if you will...collided and the energies of the collision (opposite equal reactions) would send them apart in the opposite directions, the universe being formed in between the two braines.

Last I read it was being wondered whether it would be oscillating or not.

Frankly, I don't believe the universe is "expanding".

Because the universe is not created in any point in space, it IS space, we can't comprehend with the mind what's beyond space//time. So technically we aren't "expanding", but rather the volume as we know it is increasing.

Does this mean an expansion?

Not necissarily.

If our speed is proportional to time, then the radius of the universe is not a distance but a time...15 billion years.

The volume coicides with the velocity x time, not a physical distance.

We are no larger now than we were before, though we can say that in the first trillionth of a second I think it was, the universe was the size of a Grape fruit of now...

However, this isn't a "physical" way of looking at it but a conceptual way.

A way to look at it to remove the idea of "expansion and space".

Because you can't expand into nothingness, a vaccum is not nothing, it has dimensions and time...

Get it?

We won't be any further from the point we're at now...but objects will be farther from us. In the future.

Like-wise they won't be any further from their current location, but we'll be farther from them.

Because of TIME.

It is this "physical" necessity of space, that makes us think we are expanding distantly.

But we are really just expanding Temporally...the distance is all apart of the math that governs our universe.

In fact what would be an equation to determine the distance between 2 objects based on time.

Either way, all I'm saying is remove yourselves from the idea of space and distances, and start thinking on the scale of time and speeds.

Speed being a constant expression of energy used in a certain amount of time.

So technically, nothing is moving...it is all energy used in a given amount of time.

I want to hear some comments on this before I write more about it...the theory is bubbling in my mind but I'll just go in circles without outside inputs, questions, and debates on what has been brought up already.
