For one thing the V in V/c^2 is potential MG/r not acceleration MG/r^2. (Units, units) For another the clock was not moved. The radiation of 1 curie of the stuff rose in a helium filled tunnel to the top. It is puerile to carry out whole number calculations to ridiculous extremes when differentials would do it easier. The energy is 14.4Kev with a hz frequency 3.482e18. The rate of time never changes; that is relativity's false claim. Clocks in a gravity well encounter a deprived environment and thus run slower there. Nobody compared any frequency. It's not possible. The detector was moved on a voice coil and the Doppler effect recentered the frequency to the resonance at the top filter. John Polasek
