2) there is no gravitational time dilation.
The Pound-Rebka experiment confirms a fragment (not other fragments) of Einstein's inconsistent theory of relativity if:
1) photons do not accelerate in a gravitational field.
2) there is gravitational time dilation:
Chapter 14: "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."
I would like to thank Pentcho Valev for the amount of reading he does. He reads in many languages and is a great presence on the General Science Journal.
