There is ZERO experimental evidence that any of those 10^500 string theory worlds exist, and that is exactly why a lot of people are getting fed up with string theory. Some say that a theory that predicts 10^500 unobservable things is not a theory of everything but a theory of anything which is equivalent to a theory of nothing. > > Do you think we are just extraordinarily lucky that the one universe you > suppose to exist happened to had laws that were amenable to life? > No, I don't think luck entered into it.

The second law of thermodynamics would hold true in all 10^500 universes too although that may be closer to a law of logic than a law of physics. > > So you deny the existence of anything you cannot see? > I deny anything that contradicts experimental results. > >> >> The obvious explanation is that having a perfectly valid mathematical >> structure may be necessary for existence but it is not sufficient because >> physics is more fundamental than mathematics >> > > > > Why is a universe defined by these laws reified, while others are not? > Physics!

Krauss spends an entire long chapter explaining the various meanings of "nothing" and of "vacuum". And on the first page admits he will not be able to satisfy his critics who want him to explain how something can come from nothing that is so nothing that it doesn't even have the potential to be something, but Krauss shouldn't feel bad about that because even God can't make a rock so heavy he can't lift it. >> >> >> Do you really think Bruno has done any better at answering these >> problems, or any problems? >> >> > > > > Yes. > I beg to differ. > >>> > >>> >> >>> >>> It >>> [mathematics] >>> answers the mind-body problem, >> >> >> >> >> >> That is news to me!
