Roberts Roberts if the gravitational redshift factor 1+V/c^2 confirmed
experimentally by Pound and Rebka is consistent with Einstein's 1911
equation c'=c(1+V/c^2), is it also consistent with the equation c'=c
+v, where c' is the speed of light measured by an accelerated
observer, in the absence of a gravitational field, and v is the
relative speed of the light source and the accelerated observer? You
could remember the following discussion of ours:

Pentcho Valev asked on sci.physics.relativity: CAN THE SPEED OF LIGHT
EXCEED 300000 km/s IN A GRAVITATIONAL FIELD? Tom Roberts answered:
"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)." Tom Roberts tjroberts@lucent.com
