How big was the universe just before the Big Bang occurred?

Answer 1

Undefined.

Answer 2

While no person here can give you a definitive response to this question that is totally correct beyond a shadow of a doubt, let me suggest to you that it was vast beyond your total comprehension, and that the Big Bang concept is not necessarily the creator of "everything" in the Universe. Over time there may have been multiple Big Bangs. Nothing suggests that there was only one event. That is the conclusion that everyone just naturally jumps to after years of indoctrination with the myth of creation within 7 Days. Since the current discussions place the Earth's age at some 5 Billion Years, is there anyone that has evidence of nothing being older than 5 Billion Years? No. In fact some things may indeed be older than 10, 15, or 20 Billion Years.

Isn't it interesting that some respondents are willing to parrot back words or phrases that someone else suggested as possible therory with no other information? To me, that suggests that some people are willing to take the path of least resistance.

Answer 3

Most of the people who have answered this question already, are correct. The beginning was infinitely small. To explain this, it would be helpful to view it like this. At 1 second, it would have been smaller than it was at 2 seconds. At 1/2 second, smaller than it was at 1. This can go on forever as we know. 1.00x10^-Infinity seconds. This explanation here is the most practical answer as of now but it is not for sure, as nothing is. The closer we near the big bang, the more warped "time space" would be, thus bringing us several issues, such as: Events taking place in no existence of a "time space" relationship. Any topic of this nature is still theoretical and NOTHING is fact.

I assume that this question means to say; "How big was the Universe right at the beginning or shortly after the "Big Bang". As of now, existence is not accepted before the Bang.

Answer 4

Theoretically, the Big Bang was the creation of the Universe, so to ask the question how big the universe was before it was created makes no sence.

Answer 5

The scientists don't know because they are still looking for the clues of the existence of the Big Bang which is still just a theory. For all we know, there is no Big Bang. The universe is forever which means that there is not limit. I doubt if anyone could " step out of universe " and enter into another different kind of space. We could let our imagination run. But we human being are just a almost unseen drop in the universe. Even our planet Earth is almost unseen if we could look from outside; what that outside is.

Answer 6

Nobody knows anything about the time of the Big Bang or before. We know a lot about times just a faction of a second after.

Answer 7

assuming the universe is infinitely big, it therefore has an infinite mass, which means at that point, it had an infinite gravity, which means it was infinitely small, infinitely dense, and gave off an infinite amount of energy

assuming the universe is not infinitely big, it was still cramped in a very small space, and you are asking about a point in time before time even existed, so i would say it was infinitely small at one point in time

Answer 8

Why are there so many doofuses out ther that think that anything was detectable BEFORE the "Big Bang".

The "Big Bang" is the beginning of everything we know about our reality, dearie. So please get into your head that anything BEFORE is unknowable.

You can speculate all you want to, but it's speculation in the absence of any evidence at all.

Answer 9

It was a singularity. An infinitely small point.

0 cubic metres.
0 inches x 0 inches x 0 inches.

Answer 10

nothingness...

for time and space was not yet formed.
