What Dr. Daniel Gezari (CalTech) did is to put an end to heliocentrism for good.
https://arxiv.org/vc/arxiv/papers/0912/0912.3934v1.pdfDr. Daniel Gezari emitted a pulse of photons from a point on earth, bounced those photons off a reflector on the moon, and then recorded the photons’ arrival time at that same point on earth.
One needs both the orbital and rotational Sagnac to calculate the correct timing, there is no way around that.
The lunar laser ranging experiment is an astronomical version of the Sagnac experiment.
However, G. Sagnac used the fringe-shift method to measure indirectly light travel time;
while Dr. Daniel Gezari uses clocks to measure directly light travel time in both directions.
Shooting light to the moon has to do with the behavior of light like GPS.
The arrival time of light to a receptor is influenced by the motion of
the receptor relative to the earth: this is the basic discovery of G. Sagnac.
This fact has to be incorporated into the lunar laser ranging calculations.
Here is a basic reference which confirms this fact:
Ring-laser tests of fundamental physics and geophysics, G.E. Steadman, 1997, pg 15
"Motion of the Earth-Moon system in orbit around the Sun would average out in a two-way measurement, and only appear as a small (∼3 m/s) second-order residual."
Because of the two-way averaging, the orbital Sagnac effect registered is smaller than usual, however it is not 1/365 of the rotational Sagnac effect, in fact even in the diluted form permitted by the two-way averaging calculation, it represents a significant percentage of the rotational Sagnac effect.
THE SMALL (~3M/S) SECOND ORDER RESIDUAL IS THE ORBITAL SAGNAC.
For instance, the Earth’s full 30 km/s orbital velocity along the line-of-sight would produce a second-order residual velocity of only ~3 m/s, so we cannot preclude the possibility that some part of the 8.4 m /s difference between co and c measured here is a real second-order residual due to motion of the Earth-Moon system relative to an absolute frame.
THE 8.4 M/S DIFFERENCE IS THE ROTATIONAL SAGNAC.
Dr. Daniel Gezari:
For instance, the Earth’s full 30 km/s orbital velocity along the line-of-sight would produce a second-order residual velocity of only ~3 m/s, so we cannot preclude the possibility that some part of the 8.4 m /s difference
3/8.4 = 0.357
1/365 = 0.00274
0.357/0.00274 = 130.3
Moreover, Dr. Gezari found something as extraordinary: the speed of light is a variable.
Abstract: The speed of laser light pulses launched from Earth and returned by a retro-reflector on the Moon was calculated from precision round-trip time-of-flight measurements and modeled distances. The measured speed of light (c) in the moving observers rest frame was found to exceed the canonical value c = 299,792,458 m/s by 200±10 m/s, just the speed of the observatory along the line-of-sight due to the rotation of the Earth during the measurements. This result is a first-order violation of local Lorentz invariance; the speed of light seems to depend on the motion of the observer after all, as in classical wave theory, which implies that a preferred reference frame exists for the propagation of light. However, the present experiment cannot identify the physical system to which such a preferred frame might be tied.
