Just got back from Hilton. Surprisingly Sean Carroll was there asked a question but I forget what it was. Lenny looks great - very Regal Shakespearean, but with the voice of Sid Caesar in The Show of Shows. He even had a slide of Woody Allen. Linde is also a good Russian comedian. Linde gave an impassioned impromptu answer at end to a question showing is real motivation for the landscape multiverse before in early 80's really identical to my own - more on that in another message. I have almost finished Peter Woit's book "Not Even Wrong." Peter writes well and is very convincing so it was propitious that I went to hear Lenny and Linde speak on how inflation and string theory reinforce each other in a way not totally disconnected from up-coming experiments like PLANCK NASA Probe. Lenny says that even a positive space curvature of 10^-3 would be trouble for multiverse-inflation. Lenny admits to the basic issues raised by Woit, but the situation is more complex. More on this to come. The situation is not as bad as Woit paints it, but not as good as Lenny wishes. When I spoke to Lenny personally he agreed that signal nonlocality using entanglement (a violation of orthodox QM - see papers by A. Valentini) would make the landscape directly observable, but it would spoil other parts of his theory connected with no-cloning. Lenny said he is not ready to move into that area of speculation - so I guess it's up to me (also Cramer's retrocausality experiment will be crucial). Someone mentioned Lee Smolin and Lenny said "who"? He pretended not to know of Smolin's work - a joke. ;-)

PS Krauss showed how dark energy proves Worst Possible World, i.e. life not sustainable. Some talk about string theory as religion.
