An article at Nature Physics. One can only see it if one pays, but this is the abstract.
Was the Universe before the Big Bang of classical nature, described well by a smooth space–time? Or was it in a highly fluctuating quantum state? This is one of the most basic questions that we may ask once it is accepted that there was something before the Big Bang. Loop quantum gravity applied to isotropic models has shown that the quantum evolution of a wavefunction extends through the Big Bang. Although a general demonstration is still lacking, this may suggest that calculations, and possibly future indirect observations, may allow us to see the Universe as it was before the Big Bang. Here, we analyse an explicit model with a pre-Big Bang era, indicating limitations that would imply that it is practically impossible to answer some of our questions. Assumptions (or prejudice) will remain necessary for knowing the precise state of the Universe, which cannot be fully justified within science itself.
I suspect I wouldn't understand it, even if I read the whole thing, so that's about enough. But the interesting thought there is the prospect of modeling what happened before the Big Bang. Would be fun if we had some new time coordinates, just as A.D. and B.C., so how about B.B.B. for Before Big Bang, and A.B.B. for After Big Bang, of course. Big Bada Boom.

Yeah, it is a bit silly thinking about what happened before time. A paradox, because one uses imprecise words. There is an outside the universe, of course, but it wouldn't be measurable in the space and time that it is outside of. Wouldn't be "before" and it wouldn't be X lightyears in any direction.

I’m not sure where you are getting your info, but good topic. I needs to spend some time learning more or unasietdndrng more. Thanks for wonderful info I was looking for this information for my mission.
