String theory split
A few people mentioned an article in the San Francisco Chronicle describing the current support and skepticism around string theory in the physics community to me. It’s worth a read. I would have liked to see some comments about aspects of theory—signs of the Higgs particle or supersymmetric structure—that should become testable at CERN‘s Large Hadron Collider in 2007. It’s worth noting that, since some of its opponents are quoted in the article, we would already be exploring this energy regime at the Superconducting Super-Collider, if it had been ready by its revised completion date of 2003. (You didn’t think this was a new argument, did you?)
