The error is in Valev's gross misunderstanding of relativity, not in
relativity itself. And it is almost certainly not his only error.

Einstein learned something important between 1905 (SR) and 1915 (GR),
and the rest of the physics community has also learned it. Valev REFUSES
to learn it: SR is an APPROXIMATION to GR, and that postulate holds only
in SR; in GR the constancy of the vacuum speed of light is limited to
local measurements. shrug

OK Roberts Roberts I agree Einstein criminal cult has learned
something but then let us analyse this something:

Sure, depending on the physical conditions of the measurement. It can
also be less than "300000 km/s" (by which I assume you really mean the
standard value for c). And this can happen even for an accelerated
observer in a region without any significant gravitation (e.g. in
Minkowski spacetime).

Albert Einstein and Pentcho Valev agree with you Roberts Roberts and
additionally claim that the speed of light varies with the
gravitational potential in accordance with the equation c'=c(1+V/c^2).
For the accelerated observer in Minkowski spacetime, the application
of the equivalence principle converts c'=c(1+V/c^2) into c'=c+v, where
v is the relative speed of the light source and the observer.

Roberts Roberts, do you accept the elaboration on your excellent
analysis made by Albert Einstein and Pentcho Valev? If you do not
accept the equations c'=c(1+V/c^2) and c'=c+v offered by Albert
Einstein and Pentcho Valev, please Roberts Roberts give the correct
equations that describe how the speed of light varies with the
gravitational potential, and also how the speed of light varies with
the relative speed of the light source and the accelerated observer in
Minkowski spacetime.
