> Sean Carroll is Stenger-lite. I read some of his stuff and he is slightly more sensible.-An other entry from Carroll with this paragraph:
"In this case, unlike the previous one, time could end (or begin), because time was only a useful approximation to begin with, valid in a certain regime. -This kind of scenario is exactly what quantum cosmologists like James Hartle, Stephen Hawking, Alex Vilenkin, Andrei Linde and others have in mind when they are talking about the "creation of the universe from nothing." In this kind of picture, there is literally a moment in the history of the universe prior to which there weren't any other moments. There is a boundary of time (presumably at the Big Bang), prior to which there was ... nothing. No stuff, not even a quantum wave function; there was no prior thing, because there is no sensible notion of "prior." This is also interesting, and important, and worth writing a book about, and it's another one of the possibilities Lawrence discusses."-http://blogs.discovermagazine.com/cosmicvariance/2012/04/28/a-universe-from-nothing/-Vilenkin just produced a paper noted here with this view. There was a beginning of tome and universe from nothing.
