I haven't been following very closely, but I'd find that quite surprising.<br /><br />What little I'd heard seemed more like, "given some kind of pre-existing backdrop with something like the known laws of physics (possibly unifying relativity and quantum mechanics), big bangs are likely to spark off as natural occurrences, so you don't have to worry about 'where did the seemingly specific/odd initial conditions of our universe come from?'" Which didn't surprise me much, as I'd heard scientists advance that sort of theory before. And Hawking's picture may only require gravity to start big bangs.<br /><br />That, of course, doesn't answer people who go on to ask, "where did the background with the known laws of physics come from?" But as you note, that question is stupid.Dannoreply@blogger.com
