Of course you can. You didn't read what I wrote. You time a muon in
flight the same way you could a car on the highway: you time its
crossings on successive, spaced gates. (Note you don't have to follow
the car all the way from the garage to do so.) You make a scintillator
paddle triplet, with each paddle separated by some appreciable
difference (say, 20m), and then the signals from each of the
scintillators to an o'scope or a TDC by an equal length cable. 20 m
would be about 60 ns if the speed were as high as c, trivial to
measure by either of the devices mentioned. The presence of the MIP
signal in all three paddles assures that you are seeing the passage of
the muon. You measure the distance, and you measure the time it takes
the muon to cover that distance. You have a direct measurement of the
velocity. It does not exceed c. *Measured*.

It might do you good to go into the laboratory to see for yourself,
rather than just jacking around with piddly little ideas.

That only proves those experiments are biased by
relativistic formulas.

Uh-huh. Congratulations, you've just fell face-first into Swamp Henri,
where one emerges from the muck with the belief that if simple
experiments show that one's ideas are hooey, then there is obviously
something wrong with the experiments and a cover-up to boot.

Time dilation is not an observable
by definition,

What on Earth gave you that ridiculous idea?

it is just an interpretation to explain an
observable. You can't label single muons to keep track
of them,

Why not? I produce them one at a time and I watch them leave little
energy deposits in plates of PVT I put in their path. It's not rocket
science.


You're predefining the path the muons must follow.
By putting plates of PVT along the path you assumed
those muons will follow, and by those muons leaving
little energy deposits in the plates. you are perturbing
the motion of those muons is such a way that the outcome
of the experiment will be biased. Why don't you put
those plates of PVT along an arbitrary curved path,
and test whether those muons could then travel a longer
distance in the same time?. It is clear that when muons
are not observed through intermediate detectors they
behave differently. Is that the kind of experiments you
perform to test SR with success?
