Not well, according to Peter Woit at Not Even Wrong (June 27, 2011):
The opening talk was by David Gross, who tried to address the question “Where do we stand?” for string theory. He claimed the field is “extremely healthy”, “vibrant and exciting”, “making enormous progress in a variety of areas’”, with “stupendous progress” in N=4 planar SYM. At the same time, he acknowledged that it was “very sobering” that string theory was 43 years old.
In the past, Strings XXXX conferences often featured a call for progress towards making predictions that could be tested at the LHC. With LHC data now coming in, Gross acknowledged that this had been a failure: there are no string theory LHC predictions. He put a positive spin on this by noting that the lack of any BSM signal at the LHC so far is not a worry for string theory, since string theory can’t be tested at the LHC. As for the lack of any supersymmetry signal so far, he says that “I personally am not yet worried”, while acknowledging that some people are becoming pessimistic. While no SUSY is not a worry for string theory, he feels that “it would be awfully nice for string theory if SUSY appeared”.
Instead, we’re hearing stuff like “The most important product of knowledge is ignorance,” which no one ever says if they’ve just discovered something useful.
Woit also thinks the multiverse is taking a beating. Not in popular culture. Thoughts?
