I don't believe Science can provide any information regarding the state of the universe prior to the big bang. The String Hypothesis (string theory is a misnomer because there is insufficient data to call it anything more than a hypothesis) states that there may be other universes that existed prior to the big bang, but I do not believe it provides even speculation regarding the states of those universes, or the state of our universe prior to the big bang.<br /><br />I don't believe current theory says there was "nothing" prior to the big bang, but rather that there was a massively dense singularity. I don't believe there is any specualtion regarding for how much time that singularity existed. Indeed, it is unclear and probably unlikely that time existed prior to the big bang. <br /><br />Finally, the size of the singularity is also completely unknown. All we know is that everything in the visible universe came from a singularity that was smaller than the planc constant. But the singularity itself could have been of unlimited size. For example, the singularity could have been light years across, rather than smaller than the planc length. If it was then the universe is now trillions of light years across, rather than the 80 or so billion light years across that is part of the universe that we see. (I know that we can only see about 13 billion light years away, but those galaxies which were 13 billion light years away when they sent the light we now see have continued to recede from us due to inflation such that they are believed to now be about 80 billion light years away).<br /><br />What is really mind blowing, is that as I understand it, there is nothing to prevent the singularity from being of infinite size and density such that at the moment before the big bang the universe is infinite size and after the big bang the universe has remained infinitely sized while continuing to expand. How something that is infinitely sized can expand is beyond my comprehension
