Default Gravitational Time Dilation Does Not Exist

Ideologues in the Einstein cult teach that the gravitational redshift, as measured in the Pound-Rebka experiment, gloriously proves Einstein's gravitational time dilation:

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. This was a notable feat indeed, considering that they were able to measure a frequency shift of gh/c^2 (which is only a few parts in 10^15) to within 1% accuracy." http://www.personal.kent.edu/~fwilli...Relativity.pdf

Question: "What is the greatest Physics experiment that has ever been done and why is it so good?" Jim Al-Khalili: "For me it was an experiment carried out by two Americans in the early 1950s and regarded as one of the classic tests of Einstein's General Theory of Relativity. Their names were Robert Pound and Glen Rebka and they proved that gravity really slows time down." https://www.harriswestminstersixthfo...al-khalili-obe

Yet there are cracks in Einstein's ideology:

Albert Einstein Institute: "...you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..." http://www.einstein-online.info/spot...te_dwarfs.html

Banesh Hoffmann (p. 139): "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." http://www.amazon.com/Relativity-Its.../dp/0486406768

The gravitational redshift, as measured in the Pound-Rebka experiment, proves that the speed of light falling in gravity varies as per Newton. This implies that gravitational time dilation, the miracle Einstein fabricated in 1911, does not exist:

R. V. Pound and J. L. Snider, Effect of Gravity on Gamma Radiation: "It is not our purpose here to enter into the many-sided discussion of the relationship between the effect under study and general relativity or energy conservation. It is to be noted that no strictly relativistic concepts are involved and the description of the effect as an "apparent weight" of photons is suggestive. The velocity difference predicted is identical to that which a material object would acquire in free fall for a time equal to the time of flight." http://virgo.lal.in2p3.fr/NPAC/relat...iers/pound.pdf

"To see why a deflection of light would be expected, consider Figure 2-17, which shows a beam of light entering an accelerating compartment. Successive positions of the compartment are shown at equal time intervals. Because the compartment is accelerating, the distance it moves in each time interval increases with time. The path of the beam of light, as observed from inside the compartment, issue therefore a parabola. But according to the equivalence principle, there is no way to distinguish between an accelerating compartment and one with uniform velocity in a uniform gravitational field. We conclude, therefore, that A BEAM OF LIGHT WILL ACCELERATE IN A GRAVITATIONAL FIELD AS DO OBJECTS WITH REST MASS. For example, near the surface of Earth light will fall with acceleration 9.8 m/s^2." http://web.pdx.edu/~pmoeck/books/Tipler_Llewellyn.pdf

"Contrary to intuition, the speed of light (properly defined) DECREASES as the black hole is approached." http://www.physlink.com/Education/AskExperts/ae13.cfm

This prediction of Einstein's general relativity is actually a fudge factor reconciling the nonexistent gravitational time dilation fabricated by Einstein in 1911 and the gravitational redshift predicted by Newton's theory. Gravitational time dilation and gravitational redshift are only compatible if the speed of light falling in gravity absurdly DECREASES (the acceleration of falling photons is NEGATIVE, -2g near Earth's surface):

Relativity 3 - gravity and light https://www.youtube.com/watch?v=FJ2SVPahBzg

"...you will find in section 3 of that paper Einstein's derivation of the variable speed of light in a gravitational potential, eqn (3). The result is: c'=c0(1+φ/c^2) where φ is the gravitational potential relative to the point where the speed of light c0 is measured. Simply put: Light appears to travel slower in stronger gravitational fields (near bigger mass).. [...] You can find a more sophisticated derivation later by Einstein (1955) from the full theory of general relativity in the weak field approximation. [...] Namely the 1955 approximation shows a variation in km/sec twice as much as first predicted in 1911." http://www.speed-light.info/speed_of_light_variable.htm

"Thus, as φ becomes increasingly negative (i.e., as the magnitude of the potential increases), the radial "speed of light" c_r defined in terms of the Schwarzschild parameters t and r is reduced to less than the nominal value of c." https://www.mathpages.com/rr/s6-01/6-01.htm

Einsteinians measure the gravitational redshift (in improved versions of the Pound-Rebka experiment) and then inform the gullible world that they have measured gravitational time dilation, the miracle fabricated by Einstein in 1911:

"A new paper co-authored by U.S. Energy Secretary Steven Chu measures the gravitational redshift, illustrated by the gravity-induced slowing of a clock and sometimes referred to as gravitational time dilation (though users of that term often conflate two separate phenomena), a measurement that jibes with Einstein and that is 10,000 times more precise than its predecessor." http://blogs.scientificamerican.com/...ted-precision/

"Einstein's relativity theory states a clock must tick faster at the top of a mountain than at its foot, due to the effects of gravity. "Our performance means that we can measure the gravitational shift when you raise the clock just two centimetres (0.78 inches) on the Earth's surface," said study co-author Jun Ye." http://www.theguardian.com/science/2...-billion-years

The Pound-Rebka experiment unequivocally proved Newton’s variable speed of light, which means that it disproved the gravitational time dilation.
