what was the univers volume 1second before the big bang?

Answer 1

We cannot say.

At the moment we only have information from when the big bang happened to like 1 billionth of a second.

We do not know what was before the Big Bang as the universe is time and space and everything. Anything before there has a negative time which is impossible..

Answer 2

I'll just parrot all who came before me: We don't know. Since time began with the big bang that created our universe, nothing could existed before then.

They have, however, kindly left me with one theory that neatly explains what MIGHT have been the universes' volume (not our universe, of course, a previous universe) 1 second before the Big Bang that created our universe.

You ever heard of the Oscillating Universe Theory?

You know, Expanding/Contracting = Bang/Crunch = Oscillating Universe Theory.

In essence, it says the universe (this one we're living in now) is kinda like a rubber band. Forever (not our forever, but all the forevers that came along before our universe and all that will come along after our universe, too) it expands after a singularity does it's Big Bang number until it reaches a certain point and then all the matter in the universe starts to rush back into the "center" again, like a rubber band snapping back. Eventually another singularity is formed and then, another Big Bang and a new universe.

And on and on and on.

Forever.

Therefore, if one believed this cosmological theory, then the volume of the last universe 1 second before the big bang that created our universe was pretty d*mn dense indeed.

As the late, great Carl Sagen said so eloquently, we are all made of star stuff.

Answer 3

We cannot say for sure.

We have to remember that the Big Bang Theory is still only a theory... though it is the most logical theory which seems to fit the most data.

Beyond that, other factors about the universe need to be calculated using the equation, density = mass/volume. Therefore, mass/density = volume. Because the Big Bang theory assumes that matter can be neither created nor destroyed, and that all mass and energy in the universe was present at the time of the Big Bang, it can be assumed that , for all intent and purpose, mass is infinite. It can also be assumed that because all of this mass is compressed into the smallest possible volume, that density is also infinite. Therefore, volume = infinity/infinity, which for all intent and purpose = 1.

The question is 1 what ? One cubic meter, one cubic centimeter, one cubic femtometer ?

We, at the present time, really have no way of answering this question... or of really even knowing if these terrestrial measurements are even valid at such masses , given the effect of mass on gravity, volume, density, and as is eveident in the way you asked this question... even time.

Good question... many a theory can be espoused... many a calculation can be advanced... yet none can guarantee you the kind of answer you are looking for.

Congratulations on formulating such a question. Not many people think about such abstract concepts in such concrete terms. I am truly impressed.

I believe I can say this for sure: 1 second beofre the Big Bang, the universe was still contracting 1 sec. prior to the Big Bang event which gave rise to our present, expanding universe.

Answer 4

One second before the Big Bang the volume of the Universe was 0. The Universe did not exist.

Answer 5

It is meaningless to ask about time before the Big Bang, since space and time were created in the aftermath. Since time did not exist, the unit "one second" has no definition.

But prior to the Big Bang the volume of the Universe was zero, since spacetime was nonexistent.

Answer 6

It depends.
Currently is it theorized that there was a pre-bang universe.
The relevant theories are referred to as, loop quantum gravity and string theory.
Both indicate a pre-bang universe, but at this time, neither can say what was or could have been before the Big bang.

Answer 7

That's impossible to answer. We can't measure events which took place before the Big Bang.

Answer 8

This universe is volume itself, it cannot be measured. Before the big bang was gravity, there was time and there is God.

Answer 9

Great question.

You won't like the answer, though.

Time and space were created in the big bang. That means that time didn't exist "before" the big bang. In other words, there was no "before the big bang."

Answer 10

I have heard it was infinite mass then collapsed under it's own weight turned supernova or similar with the pressure of the collapse and BANG or BIG BANG.
