Unlike a photon a muon has a nonzero rest mass, therefore a muon can NEVER travel at the speed of light and it is possible to slow them down, and if an experimenter is worth a damn he's going to make sure that relative to his lab equipment it has come to a rest, or at least is moving very slowly, before he measures it's half-life. * *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* flk -- You received this message because you are subscribed to the Google Groups "Everything List" group.
