MUON DECAY IN DIVINE ALBERT'S WORLD

http://www.scribd.com/doc/193655703/...and-Relativity
Sean Carroll: "Muons decay very quickly, in about 2 microseconds. They can be used, in some sense, as a clock. Traveling through interstellar space in the form of cosmic rays are protons that smash into atoms in Earth's upper atmosphere. They create pions and other elementary particles, and those quickly decay into muons. The upper atmosphere where the muons are created is about 15-20 km above the Earth, and the muons should decay after traveling about 1 km, yet they're able to reach the ground on Earth. Why do muons reach us before decaying? The answer is that their clocks - their lifetimes - are not ticking in the same way as ours. Because muons are moving so fast with respect to us here on Earth, they "feel" less elapsed time. To them, it takes less than 2 microseconds to go from the Earth's upper atmosphere to the Earth itself."

"The idea of this experiment is, in effect, to compare the mean time from the creation event to the decay event (i.e. the mean life) of muons at rest with the mean time for muons in motion. Suppose that a given muon at rest lasts for a time tb. Equation 5 predicts that its life in a reference frame with respect to which it is moving with velocity v, is (gamma)tb, i.e. greater than its rest life by the Lorentz factor gamma. This is the effect called relativistic time dilation. (...) In this experiment you will observe the radioactive decay of muons and measure their decay curve (distribution in lifetime) after they have come to rest in a large block of plastic scintillator, and determine their mean life. From your previous measurement of the mean velocity of cosmic-ray muons at sea level and the known variation with altitude of their flux, you can infer a lower limit on the mean life of the muons in motion. A comparison of the inferred lower limit with the measured mean life at rest provides a vivid demonstration of relativistic time dilation."

Note that when Einsteinians refer to muons "at rest" which "decay very quickly", they mean that those muons "come to rest in a large block of plastic scintillator". That is, any time a muon crashes into the block and its speed instantly changes from about 300000km/s to zero, Einsteinians sing "Divine Einstein", tumble to the floor, start tearing their clothes and go into convulsions. Why? Simply because rationality in today's science is so devastated that, when the terrible crash quickly disintegrates the muon, Einsteinians can safely say "Lo, a quickly disintegrating muon at rest!" (nobody cares to contradict them) and infer that non-crashing (moving) muons live longer than crashing ("at rest") muons thanks to time dilation, the glorious consequence of Einstein's 1905 constant-speed-of-light postulate.

In a world different from Divine Albert's world, the short lifetime of muons "at rest" would be compared to the short lifetime of a driver whose car has come to a sudden stop into a wall:

"In order to measure the decay constant for a muon at rest (or the corresponding mean-life) one must stop and detect a muon, wait for and detect its decay products, and measure the time interval between capture and decay."

Experiment 1: The lifetime of muons at rest (...) Some of these muons are stopped within the plastic of the detector and the electronics are designed to measure the time between their arrival and their subsequent decay."

"Les muons qui arrivent au niveau du détecteur sont des particules ultra-relativistes dont la vitesse est proche de c et l'énergie comprise entre 7.5 MeV et 7.5 GeV La détection s'effectue grâce à deux scintillateurs et un bloc de verre au plomb. Les deux scintillateurs mesurent le passage d'une particule cosmique. Le verre au plomb arrête un certain nombre de particules, qui se désintègrent : on mesure alors leur temps de désintégration."
