From Columbia mathematician Peter Woit at his blog Not Even Wrong:
Back in 2003-4 I never would have believed that the subject would end up in the state it finds itself in now. With the LHC results removing the last remaining hope for observational evidence relevant to string theory unification, what we’ve been seeing the last few years has been a concerted campaign to avoid admitting failure by the destructive tactic of trying to change the usual conception of testable science. Two examples of this from last week were discussed here, and today there’s a third effort along the same lines, Quantum Multiverses, by Hartle. Unlike the others, this one includes material on the interpretation of quantum mechanics one may or may not agree with, but of no relevance to the fundamental problem of not having a predictive theory that can be tested.
I’m wasting far too much time discussing the obvious problems with articles like this, to no perceptible effect. Hartle like the others completely ignores the actual arguments against his position (he lists some references. describing them as “known to the author (but not necessarily read carefully by the author)”). … More.
Woit’s right, of course, but it is not clear what can be done about the problem of “the destructive tactic of trying to change the usual conception of testable science” if we cling to naturalism (nature is all there is). If we do, naturalism will kill science and post-modern post-scientists will divide up the spoil.
But at least today’s scientists chose that. It was not forced on them.
