... Confirmed by Pound & Rebka at Harvard around 1960. A light beam with “wave length” 1.0 in the basement had a “wavelength” of 1.000000000000002455 at the building roof. Therefore, a clock in a gravitational field will be measured to run slower than that same clock away from the gravitational field. ...
