| The Pound-Rebka experiment fraud:
| http://en.wikipedia.org/wiki/Pound%E2%80%93Rebka_experiment
| "The Pound-Rebka experiment is a well known experiment to test Albert
| Einstein's theory of general relativity. It was proposed by Robert
| Pound and his graduate student Glen A. Rebka Jr. in 1959, and was the
| last of the classical tests of general relativity to be verified (in
| the same year). It is a gravitational redshift experiment, which
| measures the redshift of light moving in a gravitational field, or,
| equivalently, a test of the general relativity prediction that clocks
| should run at different rates at different places in a gravitational
| field. It is considered to be the experiment that ushered in an era of
| precision tests of general relativity. (...) When the photon travels
| through a gravitational field, its frequency and therefore its energy
| will change due to the gravitational redshift."
| David Morin (p. 4): "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."
| QUESTION: If, in a gravitational field, the speed of light varies
| exactly as the speed of cannonballs does, in accordance with Newton's
| emission theory of light, would Pound and Rebka have measured the same
| "frequency shift of gh/c^2"? It is easy to show that the answer is an
| unambiguous yes (Einsteinians occasionally admit that). How then can
| the Pound-Rebka experiment be "the experiment that ushered in an era
| of precision tests of general relativity"?

The tests are precise, the results are relativity fails them.

Test of GR.

Synchronize two vacuum enclosed identical horizontal light clocks
side-by-side and leave to run for 6 months in two identical chest
freezers (for environmental control). Note any relative drift.

Place one horizontal light clock at the top of the Burj Khalifa
and leave the other at the base. Leave to run for 6 months.
Bring the clocks together again, note any relative drift.

If the clocks DO read the same count (with drift allowed) then NIST
got it wrong, there was no time dilation due to altitude difference.

If the clocks do NOT read the same count (with drift allowed) due to
time dilation then NIST got it wrong, the speed of light cannot be a
universal constant.

Either way, NIST are useless yankee wankers and WRONG.
