OK. Now by your knowledge, which of those
experiments does not use 2-way propagation
or reflections of light ? (Reflections falsify the
speed of light measurements!)

This is not correct. *Any* determination of
speed *requires* two-way measurement. Note
that any "standard distance" confers "two-way"
to any measurement.

Than should I conclude that there is no
real, direct experimental, evidence validating
the c=const. postulate?

If by your question you meant "one way", correct. You should
also note that SR's second postulate is not required, since
Maxwell requires a constant speed of light as a result (not a
postulate), and Maxwell is covered in the first of special
relativity's postulates.

Do not forget, I am just interested in
the subject of speed-constancy here and not
the speed value itself! Note that, should the
light have "any" speed with respect to the
observer, this would not have any impact on
the measured frequency ! As such, the
speed of light is not an issue for me right now.

OK.

( On the other hand I doubt that " any
determination of speed requires 2-way
measurement" as you state above.

It is fact.

I sense a, kind of, "circus vicious" here.
But let's forget about it ,as it is not the point
here!)
I am aiming to understand how c=const
can happen.

Learn Maxwell. You will a "how", but not a "why".

But then, I want to make sure that I am
dealing with an experimental fact and not
just a postulate meant to build a theory!

Postulate not required, as previously stated.

The fact that this theory gives good results
here and there does not impress me any
more.

I am sorry.

-(-1)=1 You know what I mean! (2 mistakes
can cancel each other giving a correct result!)

All theories we have are wrong. They just happen to give useful
results oever a certain domain. The domain for special
relatiivty is fairly broad. Two mistakes cannot cancel
themselves out over the whole domain.

....
This increase of the mean lifetime is
supposed to follow the increase in energy,
so that the ratio of "disintegration" states
to the number of "relatively stable states"
is dropping .

The muon "sees" no difference in its energy
levels. How does it know how much energy
others see it having?

You think so?
O/\/\/\/\/\/\O <--------F
Then, if you push the system of 2 bodies,
would they "know" how much energy they
should get?

Do you know *anything* about muons, and how they are formed?
They are formed in a single "impulse", there is no "acceleration
history".

Note that muons do not "live longer" if high
speed protons are shot past them... except
to the protons of course.

My bottom line is : The muon behaviour
probably will be explained by quantum
mechanics without any SRT involved!

So you don't know any quantum mechanics either. *That* muons
have a "halflife" is described by quantum mechanics. That is
halflife is some proportion of some other unstable system's
halflife is covered by quantum mechanics. That the halflife is
so many microseconds in a rest frame... quantum mechanics can't
go there. Relativity, being classical, does.
