You guys are twisting my assertions, my claims are that Dufour & Prunier's replication on the Sagnac effect took the non-rotating framework of special relativity into account and proved empirically that the results were not consistent with it.

But hey thanks for strawmaning my argument by omitting D&P then knocking over Sagnac with the special relativity argument. Your random link to some bullshit about GPS doesn't change the results D&P obtained.
