# Current string-theory version of Big Bang

I always wondered what the description of Big Bang would be like in string theory.

How is it different from QFT version of Big Bang?

Thanks.

There isn't a QFT version of the Big Bang. QFT takes us back to the electroweak symmetry breaking, which was about 10$^{-12}$ seconds after the big bang. What happened before then isn't known, though hopefully the LHC will tell us soon. Incidentally http://en.wikipedia.org/wiki/Timeline_of_the_Big_Bang is an interesting related article.
