Thread: How can one reconcile the Big Bang Theory with Infinite Universe Theory?

1. How can one reconcile the Big Bang Theory with Infinite Universe Theory?

Hiya guys, I guess I should have paid more attention at school. My question is, in the Big Bang theory we are told that everything in creation was compressed into a confined space (the definition of finite as far as I'm concerned) and after the BB everything formed.

But, I've also been told that there is no center of the universe and no edge either. It is infinite.

How can both theories be reconcilled to each other?

Thanks, guys and gals.

Cheers, Dev

2. Either the universe is finite, in which case big bang makes sense, or the universe is infinite, in which case big bang is completely senseless. Big bang is based on the assumption that, since all the matter in the universe is confined to a finite space, all the gravity pulls inward. Given enough mass in a finite universe, gravity warps space-time back on itself so that the diameter equals the radius, and there is no edge. Every point in such a universe is the center.

In an infinite universe, every point is the center because in every direction, you have stuff out there, all the way to infinity.

However, due to the expansion of space, there is a finite visible universe. Light emitted from beyond the Hubble limit cannot reach us because new space is appearing between us and it faster than it is approaching us (the speed of light). In an infinite universe, every point has a different visible universe, and the visible universe from one point doesn't necessarily overlap with the visible universe from another point. In a big bang universe, all the visible universes are the same, but they have different centers.

4. i am clueless just like u lol

5. M theory suggests that the Universe we can perceive (3 dimensions and time) was created via the big bang when two membranes existing in 11 dimensions came into contact with each other. The infinite 11 dimensional universe is what our 3 dimensional universe is expanding into.

6. They can't be reconciled. One either assumes that the universe is finite or infinite. Infinite Universe Theory will replace the Big Bang Theory, since the explosion of the entire universe from nothing is impossible according to the First Law of Thermodynamics (Matter and motion of matter neither can be created nor destroyed). The First Law has never been falsified during millions of experiments.

7. Hi Glenn,

Welcome to Astronomy Forum.
This is an older thread from when this forum was under different ownership. So far as I am aware there is no one from the previous regime posting at the present time. All of the new activity on the forum occurs on threads starting from around August 2008 to the present.

Thanks so much. Glad to see that the forum is continuuing and that it is open to views other than the current Big Bang paradigm.

How was matter in the Universe created?

Why did the Universe take an infinite amount of time to appear?

Physical explanations for these questions seem to be as esoteric as they are scientific. Stephen Hawking says there was no time before the Universe, and it was created at the moment of inception of matter. Unfortunately there is no model or proven theory for showing us exactly what the first moments of the Universe looked like, or what happened, totally cutting us off from any definitive answers to how it all began or how matter was created at all. Since there is no way of seeing all the way back to time 0, we can only guess as to how the inception of matter actually happened as well as the causes of the Big Bang. I'm talking even before the "Big Bang" caused the widespread dispersal of matter across billions of light-years of Space.

This is where the Big Bang reconciles with the Infinite Universe...

The most conventional theory draws from quantum physics and say simply that nothingness itself is unstable and the entire Universe was created from a single insertion of unimaginably dense matter from another dimension. Tough for me to wrap my head around this one, and like all the other theories for the creation of the Universe before the Big Bang, it's all conjecture until we know more...

11. What's north of the north pole?

That's basically what you're asking. If time started with the big bang, as is currently believed, then it doesn't make any sense to ask what happened before that.
Maybe there's another dimension to time that we don't know about, that in a larger sense, allows all events to happen in a progression that has no beginning or end.

There's also the anthropogenic answer which basically says the universe is the way it is because it happens that this configuration of the universe is what is required for us to ask why the universe is this way. That is to say, if it were any different, we wouldn't be here to ask that question, so it must be like this for that question to even arise.

I find it extremely unlikely that we'll ever know for sure what exactly happened, since there's no way to look back when there's nothing to look back to (no time before the big bang).
What we could do is look into the future, and if we happened to see another universe come into existence, then we could theorize that that was how our universe came to be as well.
String theory, and more specifically, M Theory, has some theories as to how a universe can be started through the interaction of various strings and branes, each interaction triggering a new universe.

Here's an interesting article on the matter, at any rate:
