David Morin: "The equivalence principle has a striking consequence concerning the behavior of clocks in a gravitational field. It implies that higher clocks run faster than lower clocks. If you put a watch on top of a tower, and then stand on the ground, you will see the watch on the tower tick faster than an identical watch on your wrist. When you take the watch down and compare it to the one on your wrist, it will show more time elapsed. (...) This GR time-dilation effect was first measured at Harvard by Pound and Rebka in 1960. They sent gamma rays up a 20m tower and measured the redshift (that is, the decrease in frequency) at the top."
Gravitational time dilation is a miraculous effect fabricated by Einstein in 1911. According to him, the effect occurs even in a HOMOGENEOUS gravitational field. This means that the two clocks, although at different heights, are in EXACTLY THE SAME immediate environment (experience EXACTLY THE SAME gravitational field) and yet one of them runs faster than the other. The effect has no cause.
"Effect without cause" is not a problem in Einstein's schizophrenic world and yet the cleverest Einsteinians feel uncomfortable from time to time:

Banesh Hoffmann: "In an accelerated sky laboratory, and therefore also in the corresponding earth laboratory, the frequence of arrival of light pulses is lower than the ticking rate of the upper clocks even though all the clocks go at the same rate. (...) As a result the experimenter at the ceiling of the sky laboratory will see with his own eyes that the floor clock is going at a slower rate than the ceiling clock - even though, as I have stressed, both are going at the same rate. (...) The gravitational red shift does not arise from changes in the intrinsic rates of clocks. It arises from what befalls light signals as they traverse space and time in the presence of gravitation."
Banesh Hoffmann is an exception; all other Einsteinians teach, like David Morin, that the gravitational red shift does arise from changes in the intrinsic rates of clocks.
