If the distance traveled can be broken down into orthogonal vectors and it's the sum of those vectors, then when light makes a complete circuit back to the source it must travel at some speed out and at some speed in, along both orthogonal vectors. They have to cancel between the light in both directions. Along the vector that's perpendicular to their original motion they both go out and then in. Along the vector that's orthogonal to their motion they first go out in opposite directions, then they reverse in opposite directions, then they come back in opposite directions. Each motion of one is repeated by the other, though in a different order. But if the whole apparatus rotates then they don't quite cancel out. One will travel a small amount extra in its original direction and the others a small amount less. A tiny amount in the orthogonal direction, the sine of a small angle. Since we're talking about relativistic motion, we don't get the difference in speed over the whole path but the difference in speed over the small difference in pathlength. I think this will be negligible until the apparatus rotates at relativistic speed. > > So > > the speeds average out between the two of them, leaving you with a > > very similar interference pattern compared to the classical case. > > You would most likely get some phase shift, and possible a changing > interference pattern if the speeds of the photons changed at each > mirror.

I have hypothesised that nothing happens at the mirror except a reflection at the angle of incidence and the velocity at c in the light's own frame. Experimental evidence might show another difference, and that difference would be a confirmation of EmT, right? > It does seem extremely ad-hoc though. Of course. Isn't this how Einstein did it? First he lookerd at the experiments he needed to satisfy -- MM etc -- and he decided lightspeed should be the same always and the same in all frames, and then he worked out what else had to happen to allow that, and then he came up with some sort of semi-plausible explanation how it could happen. It isn't something that anybody would come up with from first principles, if they had been raised thinking euclidean. > >> > Both of them will spend 1/4 of their distance > >> > traveling at c+v and 1/4 at c-v etc. > > > >> Not really, as you are reflecting at (something near) 90 deg at > >> each mirror, not 180.

But when I try to think about which angle applies when v is relativistic I get confused. There might be something here that would break it either way. I don't have it thought out yet, I have one solution that has to be wrong and a second solution that might be right and I don't yet know which is which. > >> > So the diffraction pattern should > >> > be almost the same as the classical and SR case. > >> > >> I think we're getting a bit unrealistic there with how mirrors work > >:) > > > > You're a relativist and you're noodging about unrealistic > > asssumptions? > > Yeup.

Nothing unrealistic about the laws of physics being the same everywhere, or the speed of light being a constant c in the light's own frame of reference. > > Hey, if Einstein can do it, I can do it.

Thanks http://books.google.com/books?id=7xrL7h10XkQC&pg=PA7&lpg=PA6&ots=co-r6uws_f&dq=%22emission+theories%22 This is Pauli's explanation. The relevant part is on page 7 which would take special software for me to copy and paste. "Finally, according to Ritz the velocity of the reflected ray is equal to that of a parallel ray, emitted from the original light source." Pauli dismisses emission theories because of DeSitter's work on double stars. On page 8 he says that if lightspeed is not constant then circular orbits of double stars would appear eccentric. Since DeSitter did not see double stars with eccentric orbits, emission theories are disproved. And thus, the work of Androcles and Wilson starts to look important. If DeSitter is wrong then the decisive negative evidence against emission theories disappears. DeSitter saw no double stars with eccentric orbits, therefore emission theory is wrong. Something funny about that decisive evidence.... There might be other decisive evidence against Ritz's emission theory, that nobody has bothered to look for because they considered it already disproved. We won't know about that until we look.

A team of scientists working under the direction of researchers from the University of Sussex have recently discovered that Einstein did not say "inertial". Here is their well-researched evidence which took 13.5 milliseconds to carry out at great expense. http://www.androcles01.pwp.blueyonder.co.uk/inertial.JPG Everything travels at speed zero in its own frame, it is always at the origin. Otherwise it would leave its frame behind. Clearly neither of you idiots have a clue what a frame of reference is. You should both learn the basics. >> The +v is all just according to an observer, and different observers >> see different values for v >> >> So its not something a photon can 'know', because it is solely >> observer dependant. > > All the light has to do is move at c in its own frame and the observers > can all observe.

It is estimated that the extinction distance in ambient air is about 3 cms (don't ask me who determined that) but normally the air would be at rest with the mirror in this type of experiment.
