Re: SR false?

After giving Mr. Thim's experiment a few thoughts, I have to say his
setup cannot have yielded the transverse Doppler effect. The reason is
not the Lorentz transform but the rotating device. It acts like a
conductor regardless if rotating or not.

However, if the movement is linear, we have a different story.

A --->
---> B
---> C

A sends out a photon to B which is traveling at speed = v
perpendicular. A few moments later, B sends out another photon to C.
A and C are stationary to each other.

B will observer a transverse Doppler effect from A by the amount

f_B = f_A / sqrt(1 - v^2 / v^2)

However, the speed v will slow down to v' and changes its direction
to absorb the momentum of the photon received from A.

When B sends out another photon, C will also observe a transverse
Doppler effect of

f_C = (f_B' + v' * p_B' / h) / sqrt(1 - v'^2 / c^2)

Where

** p_B' = Momentum vector of the 2nd photon in which it should be
almost 90 degrees with vector v'

Afterwards, B is going to slow further to v" and changes its course
slightly.
