Applying the principle of tautological relationship of gravity and the speed of light (g=cd), solved and explained, by conventional physics misinterpreted nature of Pound-Rebka experiment. Also presented is an accurate universal formula for calculating the spectral shift between the measured points of any altitude difference, equivalent to the special and general relativistic. Eventually, demonstrated is the link between gravitational, transversal and radial dilatations as a result of speed. Implicitly, presented is the evidence of the infinitely variable nature of universal scalar, the speed of light.
