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.

the same way you can't label single electrons.
Perform a double-slit experiment to keep track of a single
muon.

This isn't a double slit. There is no interference. Perhaps you don't
understand the simple word-picture I used to describe the apparatus.
Perhaps you are groping.

Can you clarify the path a muon can follow in that
double-slit experiment? If you can't clarify a muon path
why are so sure a muon has travelled a distance R in time
t'? Didn't you know that intermediate measurements alter
the experimental results.

To order hbar, sure. That isn't a whole lot compared to 60ns over 20m.
Want to check your math again? Or are you happy just clamping your
hands over your ears and hollering, "NANANANA! I can't HEAR you!!!"
