Time and "Before" the Big Bang
I am just trying to get a feel for the general consensus on whether not not time was "created" in the Big Bang, meaning there really is no "before" the Big Bang.
As I understand it, in M Theory cosmology the (or, our) Big Bang would not be the beginning of time. For there to be brane dyamics there would have to be time, right?
What's the view on time existing before the Big Bang under Eternal Inflation?
Also, are there any other theories with interesting viewpoints out there beyond these two?
It's my understanding that regular inflationary theories don't even deal with the question at all, being outside its purview. Is that correct?
Are there any theories that do not include a time dimension? Hard to imagine one, since it would see nothing would happen w/o time? I guess perhaps we start getting into philosophy at this point, so maybe I should stop here so another one of my threads doesn't get shut down ;-)
