SUMMARY
The discussion centers on the apparent conflict between the Sagnac effect and Special Relativity Theory (SRT), particularly in the context of Sagnac ring laser gyros and fiber-optic gyros. Participants assert that the Sagnac effect does not violate SRT, as it is a prediction of the theory, and emphasize the necessity of Sagnac corrections in systems like the Global Positioning System (GPS) due to non-inertial frames. The conversation also references Ruyong Wang's experiments, which demonstrate that the travel-time difference of counter-propagating light beams in moving fibers is consistent with SRT when analyzed from an inertial frame.
