VARIABLE SPEED OF LIGHT IN GRAVITY

A light source at the bottom of a tower of height h emits light upwards. As the light reaches a stationary receiver at the top of a tower, its speed relative to that receiver is:

A) c' = c(1-gh/c^2) (Newton's emission theory)

B) c' = c(1-2gh/c^2) (Einstein's general relativity)

C) c' = c (Richard Epp, Stephen Hawking, Brian Cox)

The following analysis clearly shows that A is correct while B and C are false predictions:

"In 1960 Pound and Rebka and later, 1965, with an improved version Pound and Snider measured the gravitational redshift of light using the Harvard tower, h=22.6m. From the equivalence principle, at the instant the light is emitted from the transmitter, only a freely falling observer will measure the same value of f that was emitted by the transmitter. But the stationary receiver is not free falling. During the time it takes light to travel to the top of the tower, t=h/c, the receiver is traveling at a velocity, v=gt, away from a free falling receiver. Hence the measured frequency is: f'=f(1-v/c)=f(1-gh/c^2)."

The frequency measured at the bottom of the tower is f=c/L, where L is the wavelength. The frequency measured by the stationary receiver at the top of the tower is:

f' = f(1-gh/c^2) = (c/L)(1-gh/c^2) = c'/L

where c'=c(1-gh/c^2) is the speed of the light relative to that receiver. From the equivalence principle, c'=c(1-gh/c^2)=c-v is also the speed of light relative to an observer/receiver moving, in gravitation-free space, away from the light source with speed v. Clearly both general and special relativity are false.
