At this point I am interested only to find out
if the lightspeed was really found experimentally
constant, using cosmic sources of radiation,
and of course to learn where this information
was published and accessible for the public.

Yes. Used in MMX experiments, and yielded
a constant.

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.

....
That is why I was referring to an experiment
using ONLY one-way propagation of signals
/ light.

Impossible and meaningless in *this* Universe. The
Moon-as-shutter experiment could show aniostropy, if any were
present.

....
For example, I can imagine easily an alternative
interpretation to time-dilation found for the case
of muons.:-)

Good. Now review all the data of muons
measured at different altitudes, and with
systems that use multiple detectors at different
levels, and all yield velocity less than c.

The problem with "special case solutions" is
that they fail when you get away form the
special case... and relativity goes a lot further
before it fails.

I am not thinking of a special case solution.
I think that the behaviour of muons could be
explained by considering the increase in the
number of internal states of the muon as a
system of components rather than time
dilation.

This is a special case solution. No such "internal states" are
present, except when relative speed is present. How do they know
how fast they are going?

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?

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