String theory put to the test

I’ve just spotted an interesting piece of physics news. String theory, an esoteric and hitherto untestable attempt to unify the four fundamental forces in physics, may soon become a real scientific theory (in the Popperian sense of being open to falsification). American physicists have used the basic mathematical assumptions in string theory to make some predictions about W boson scattering. This is significant because when the Large Hadron Collider at CERN starts up in the Autumn scientists will be able to test those predictions. We will at last have a better idea of whether or not the current favourite contender as a theory of everything actually works.
