It isn't. Einsteiniana's most pernicious hoax is undoubtedly the muon
hoax. It is based on measuring the lifetime of muons "at rest". When
cosmic-ray muons bump into an obstacle so that their speed instantly
changes from about 300000km/s to zero, their forced and quick
disintegration makes Einsteinians sing "Divine Einstein" and go into
convulsions. Why? Simply because in the era of Postscientism human
rationality is so devastated that, while the muon undergoes such a
terrible crash, Einsteinians safely declare that in fact this muon is
"at rest" and, being "at rest", disintegrates more quickly than
another muon which is not "at rest", in perfect accordance with Divine
Albert's Divine Theory:

http://websci.smith.edu/~pdecowsk/muons.html
"The purpose of this experiment is to measure life time of muons
decaying at rest. Muons, produced in the atmoshere bombarded by high
energy cosmic radiation, are passing through the system of two
detectors located one above the other one. A coincidence of signals
from these two detectors (signals occuring in both detectors within
100ns) marks a particle entering the muon telescope from above and
serves as a filter rejecting many noninteresting signals from
background radiation. Some particles, with appropriate energies, will
end their flight in the lower detector (proper amount of lead between
both detectors ensures that many of them will be muons). If a stopped
particle is muon, it will decay after some time producing electron.
The time interval between signals from the muon entering the lower
detector and the electron emerging after its decay is converted by a
time-to-amplitude converter into amplitude of signal fed to the CAMAC
analog-to-digital converter (ADC) controlled by the computer. The
spectrum of time intervals is displayed in the figure below. The
expected distribution should be exponential with the exponential time
constant being the average life time of muon. The full range of the
spectrum (about channel 2000) corresponds to the time interval of
about 25 microsecond. There are not many muons with such energies that
they will end their path exactly in the lower detector (usually they
will pass both detectors and will be stopped in somewhere in the
ground), so counting rate is rather low. To collect a reasonable
number of events, the experiment has to be run a number of days."
