This was experimentally confirmed in the laboratory by the Pound-Rebka experiment in 1959 (they used the Mossbauer effect to measure the change in frequency in gamma rays as they travelled from the ground to the top of Jefferson Labs at Havard University) .
Now, suppose the Pound-Rebka experiment is performed at the surface of the Sun, Earth and other oblate spheroidal planets on the equator.
This shows that (i) the matter 'gravitational' geodesic is a quantum wave refraction effect, with the trajectory determined by a Fermat least proper-time principle, and (ii) that quantum systems undergo a local time dilation effect--which is used later herein in connection with the Pound-Rebka experiment
. A full derivation of (6) requires the generalised Dirac equation.
