If you start with the General Relativity factor = gR/c² and substitute g for half the centrifugal acceleration v²/R you arrive at the Special Relativity Lorentz transformation factor - gR/c² = v²/2R x R/c² = v²/2c² The Lorentz transformations original derivation is based on linear vector motions and the need for time dilation to reconcile the constancy of the speed of light c across different reference frames. As this v²/2c² factor provides a valid and correct adjustment to GPS satellite clock atomic half life rates whilst in orbit, one of these competing derivations is likely to be a representation of reality, but the other one must be a coincidental hoax. If back ground EM radiation or gravitational waves provide the medium relative to which light propagates its speed/wavelength energy mix then the observed constancy of c is explained. Lunar laser range tests are observational evidence of this. This paper therefore argues that the Lorentz derivation is likely to be the hoax and we no longer need special relativity's absolute time dilation.
