The ones I'd be interested in are the ones about Tests of Lightspeed from Moving Sources Experiments Using Terrestrial Sources I will regard astronomical data as suggestive but inconclusive because our interpretation of astronomical events is so shaky. So the terrestrial experiments look interesting, but lack links to let me easily check the claims myself. I will at some point find a library that lets me copy the reports, and in the meantime I am curious about which of them people here have studied and approved.

If phase were to vary by distance rather than time, and the speeds were right, you could get a phase shift from the paths being a different length. After all, it's the paths being a different length that persuades you they arrive at a different time with other theories. Try it out. One particle is emitted that travels at 1.1c, another travels at 0.9c, after 1 second they meet up. The first has traveled farther than the second. If "wavelength" is measured in distance traveled, the first has traveled an extra 2/9 light-seconds. They will not be in phase. But when I draw the diagram it will look like they have different wavelengths because the wave pictures will be shrunk on one side and stretched on the other. > > All in all, I think Wilson would be better off to go with the Ritz > > emission theory.

As I have said before, people who believe in relativity have no ground to reject theories for not making sense. I'm interested in experimental refutations, though.

There have been tests with particles travelling a nearly-c emiting photons. .. those photons do not travel at v+c (otherwise we'd see some photons at nearly 2c and some at nearly 0.

The phase shift isn't observer dependant.

Of course that's how it would go. So, how did they measure the speed of the photons? |
