So how would you describe them? AG* *I await your reply. How do you know particles have internal clocks? What form do they take? AG* * Muons are particles and are produced by high energy cosmic rays hitting atoms of air very high up in our atmosphere. The half-life of a muon is only 1.5*10^-6 seconds, that's so short that almost none of them should reach the ground, and yet a significant number of them do. That's because that half-life figure was determined in a lab that was not moving relative to the muon being measured, but the average muon made by cosmic rays is moving at about 99.4% the speed of light, and if you use the formula 1 / √(1 - (v²/c²) for time dilation you find those muons have a half life that is 9.14 times longer than the half-life of muons measured in a lab.* *John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* 8g -- You received this message because you are subscribed to the Google Groups "Everything List" group.
