Now let me see if I got this straight. A rest frame interferometer necessarily undergoes some kind of change because of some kind of velocity and MEE simply misinterprets the lack of change and there are actually two different changes that somehow cancel out...
And the Sagnac effect, which is a very well defined and well understood effect of rotation of light, now has something more to do with its translation as well as rotation...
And all of the GPS calcs that claim they are due to gravity and velocity (squared) corrections are all simply just lucky to get the right answer for location on earth...
All with just simple declarative statements of fact that appear to contradict a large body of experimental evidence, all without a single calculation. Normally answers to simple questions that include measurements and calculations help people to better understand and predict action, not obfuscate.
I simply do not know how to respond to declarations of belief that are inconsistent with measurements and calculations. You can of course believe in anything that you want as long as you are not in charge of GPS programming...or satellite navigation or precision clocks. It is not clear what predictions of action you believe are improved by rejecting the very nice system of MEE that works so darn well.
Michelson and Morley and hundreds of later experiments show that the time delays of interferometer arms at rest do not depend the orientation or location of the interferometer. Period. Motion has nothing to do this this result and it is simply an observation of fact.
Now MEE is consistent with this result and that makes a nice story that helps make GPS part of the same story and it seems all very consistent. Accurate GPS calcs include both gravity and v2/c2 time dilation, so there is no mystery there...just look it up.
Now you want to throw MEE under the bus because you can't understand why a moving interferometer is different from a rest interferometer, or why light stops at a black hole, or why light is slowed and bent by gravity.
You can spend a lifetime in these kind of rabbit holes...
