Moortel Moortel what you call "how short muons live on average" your masters used to call "muon lifetime at rest". But they don't even mention it anymore. Why? Because people now know that this "muon lifetime at rest" is one of the greatest frauds ever devised by Einstein criminal cult: http://groups.google.ca/group/sci.physics.relativity/browse_frm/thread/69ad1af61851c041? When the lifetime "at rest" is measured, by "at rest" Einstein criminal cult mean a crash undergone by the muon in which its speed changes from about 300000km/s to zero. That crash is so terrible that the muon "dies" quickly, much more quickly than muons that have not undergone the crash: http://web.mit.edu/c_hill/www/muons_paper.pdf "In this experiment, we measure two of the basic properties of the muon, namely, its mean lifetime and mass in its rest frame. We measure the decay curve of cosmic-ray muons that have come to rest in a plastic scintillator by looking for electrons produced in their decay." Pentcho Valev pvalev@yahoo.com
