Nothing is wrong with your derivation. Your conclusion that it
implies circularity is what's wrong.

I showed how to derive the formula with trivial mathematical
circularity. Does that make me as great as Einstein ...or greater...?


Well, Henri, as I explained to you in great detail, there is nothing
circular about it. You started with the presumption that c is
constant, independent of the reference frame, and used that derive the
correct rule for the addition of velocities. That is precisely the
right way to do it. Circularity would entail concluding what you
started with, and that is not what you're doing. If you will read my
response quoted above once more, you will perhaps understand that a
little better.

Henri, another way of saying it is this:
If one is speaking of how SR says things 'should be', then one must (at
least for the sake of the discussion in progress) accept the postulates of
SR and the derived conclusions.

If one is doing so, then the BaTh statement c'=c+v would be expressed (in
SR) as c' = composition(c,v) and the results will always be c.

Nothing terribly unexpected about this. But it does invalidate attempts to
say that SR requires photons leaving a moving source to know the velocity
of the target so that they arrive there at c.

....but it doesn't invalidate the concept of a single absiolute aether frame.

The other important point PD made might be reworded as "if we were to
compute the 'relative velocity' using any other rule than the composition
rule, the results would not agree with expermental data".

how would you know? OWLS has never been measured...nor can it be...

For example, two particles approach each other at v1 and v2,
if v_effective=v1+v2 were correct, rather than
v_effective=composition(v1,v2)
then dozens of years of expermental data from particle accelerators around
the world would have given much different results from those that have been
seen.

I don't think so. They are concerned with energy and the circularity of SR
would probably multiply and dive\die by the same factor somewhere..

The composition formula gives the correct results for all experiments
anyone has been able to run(as far as I know).

While this does NOT prove SR is correct, it clearly proves that we can NOT
use v_effective = v1+v2 under any circumstances where either v1 or v2 are a
significant fraction of c and get the correct (as verified by experiment)
predictions.

Bob, nobody has measured OWLS and is never likely to.

Correction: That should be 'from a moving source'.

It might be just possible to compare OWLS from two differently moving
sources...but not in the lab.

A straw man.
Also, not true.


In any case, I was not talking about the speed of light but the speed of
particles moving near the speed of light ('v1 and v2 are a significant
fraction of the speed of c').

Build your own particle accelerator, using the predictions of BaTh and see
if you can get particles to move faster than c as is implied by v_effective
=(v1+v2) rather than v_effective = composition(v1,v2).

If we lived in a universe where BaTh worked, v1+v2 would work. It MUST so
that c+v will work unless you say that c+v ONLY applies to massless
particles and THEN you must explain how the massive particles 'know' they
must go slower than c when they are surrounded by photons moving faster
than c as they would be if c'=c+v worked.

You must play by the rules of the game.
Everything must be consistent with c'=c+v. You must deal with all the
implications, you can not pick and choose which you want to deal with.

Bob, the only so called evidence AGAINST the BaTh was De Sitter's work.

Incorrect. There is a LOT more evidence against BaTh.

In 1953, however, Parry Moon and Domina Spencer analyzed a number of visual
binaries to see whether the phenomenon predicted by Bergmann would even be
visible in the first place.7 They assumed the Ritz hypothesis8, but their
computations showed that Bergmann's predicted multiple images for binaries
would not, in fact, be observed. (They do not elaborate on de Sitter's
prediction of spurious eccentricities, and they do not mention whether they
reexamined his data or not.) Hence, they concluded that visual binaries
proved absolutely nothing about the constancy of the velocity of light.

[emphasis mine]In the same article, Moon and Spencer performed a similar
analysis of spectroscopic binaries and of Cepheid variables.9 They
concluded that the Ritz hypothesis would produce spurious spectral lines,
but no such phenomenon was observed.[end emphasis]
.....
is Fox's criticism-that the observations of de Sitter and Bergmann did not
take the Ewald and Oseen extinction effect into account-still valid?
Definitely not, for by 1964 direct evidence for the validity of Einstein's
postulate on the velocity of light was provided by a number of
experimenters: D. Sadeh; T.A. Filippas and J.G. Fox; and T. Alvager et
al.14 All of these experimenters measured the velocity of gamma rays which
had been emitted by decaying subatomic particles moving at nearly the speed
of light. In every case, the velocity of the gamma rays equaled that of the
normal velocity of light in free space. In no case did the velocity of the
gamma rays behave as proposed by Ritz.

In addition to the above Earth-based experiments, in 1977 K. Brecher used
radiation from pulsars (rotating neutron stars which emit radiation in a
periodic manner) to show that the speed of light was independent of the
motion of the source.15 Neither Brecher's experiment nor the ones mentioned
in the preceding paragraph were subject to Fox's criticism. Hence,
observations of both terrestrial and extra-terrestrial phenomena have shown
once and for all that Ritz's hypothesis is invalid. .... [unquote]
