Oh! Why didn't you say so? ?! The central thing about Ritz's theory is that if the source is traveling in direction V at speed v, when a ray of light is emitted, then from then on until some nonconservative action happens to that ray, if it would otherwise be traveling at speed c in direction D it instead travels at cD + vV. While I thought the way you did it was more complicated, I thought you were saying that if the source is traveling in direction V at speed v when a ray of light is emitted in direction D, that the speed of that ray of light will be cD + vV from then on until something happens to it. It's the constant speed independent of direction that causes the trouble. But your double-star work does not particularly depend on what happens when light changes direction, right? I think it would carry over to Ritz's approach.

It's hard to find anything to work with. Mmm.. of course, the answer is simple, that ballistic theory (with each ray having a constant speed around the ring) gives no phase shift because the rays arrive at the same time. If speed somehow varies over the duration by the right ammounts, then you can get different arrival times, and a phase shift. >> They leave the emitter in phase and arrive at the detector in phase >> and it takes the same time for them to do so. >> >> The only way for them NOT to arrive in phase is if something happened >> to the rays in transit > > It would have to happen differently to the waves that have the different > absolute speeds and different directions.

Ritz (as you have described it) makes no sense when you think about it, and is refuted experimentally.
