Thank you.

I have Google searched for "Anderson's kappa" but not readily found. What specifically is it?

Very good points, thanks all of you for your comments. I know it took time out of your days to respond back to me, and I appreciate it. (I have learned along the way.) Thanks again. Live long and prosper.

I realize that assuming a radio wave travels at the speed of light in all directions to initiate synchronization of the clocks is a flaw in logic, since we are trying to prove light speed from A to B is the same as from B to A. That is why in my original post I was trying to avoid that flaw by...

OK. If my "experiment" were performed on the International Space Station (ISS), which is a "falling reference frame", that would satisfy as a "local inertial frame". The gravity field is "eliminated". But we could still test for the 1-Way speed of light in all directions, as the wheel is...

OK. Good points. If I understand you correctly, my "experiment" is a "local, weak gravitational" case, which approximates an "inertial frame". My coordinates to 1st approximation are Minkowski. Let the center of the wheel be point C, then with respect to O, the reset signals sent are two...

Yes. And this is why Einstein defined time as: the time it takes for light to travel from A to B is the same as it takes light to travel from B to A (in Special Relativity). So, in General Relativity, is the speed of light defined differently, and is it not constant for all observers.

Thank you all for your comments! Very much appreciated. I do hope that my reply here will be seen by all of you (Dale, Ibix, PeroK, Peter Donis, Saggitarius A-Star, pervect). 1. Desynchronization can occur between A and B because of the perpendicular components of O's reset signal. This...

Does the speed of light change in a gravitational field depending on whether the direction of travel is parallel to the field, or perpendicular to the field? And is it the same in both directions at each orientation? This question could be answered experimentally to some degree of accuracy...
