Hi All, String theory is a big focus of my son's Ph.D. studies at the University of Arizona. To an extent, string theory IS testable. That's true both from a theoretical standpoint (where the theory ties together some basic facts of science that can't be explained by any other known theory) and also from a physical standpoint. I understand that a new collider being built by CERN may give some indications. I certainly don't have anything like Sky's knowledge of the subject but I have a hunch that the convergence of several lines of discovery and thinking point toward the likelihood of string theory (or something derived from our present notion of it) being true. -- Best wishes, Joe
