George and I went right into > this last year. I don't care about what "you and George" went through last year. This nonsense about "displaced beams" can only be uttered by someone who doesn't know how an interferometer works. I wrote the following September 20. 2005 (which is before "last year"), it is still valid: You seem to be completely ignorant of how an interference pattern is formed, and why fringes shifts. Please take the time to read the following properly, I am using time to write it. To get an interference pattern with fringes, the beams must be diverging and overlapping. Consider this simple figure: 1 2 * * Two correlated (in phase) point sources emitting monochromatic, coherent light. (Laser and a beam splitter) --|--|--|---- screen A B C The point B is equidistant to source 1 and 2. We get a bright fringe through B. The fringe will be a straight line. The distance from the point A to point 2 is half a wavelength longer than the distance to point 1. We get a dark fringe through A. This fringe will be a bit curved. Likewise for point C, a dark fringe. Note that the reason why there are fringes at all is that the beams are diverging, so the distance from the source to the screen is different on different parts of the screen. The angle of the beams when they unite has obviously nothing whatsoever with the matter to do. The only thing that matters is the difference in the light path lengths to the two sources measured in wavelengths. The only way to make the fringes move, is to change the distance to one of the sources. If we move source 1 a bit upwards, the fringes will move to the left, and vice versa. So when fringes move, the difference between the two path lengths measured in wavelengths changes. Now let this "interferometer" rotate. Observed in the interferometer frame, the light paths will be slightly curved, so the angle with which the light hits the screen is slightly altered. But the fringes will not move, because the slightly curved light paths from point 1 to B and point 2 to B will still be equally long. The angle at which the beams hit the screen is utterly irrelevant. And please don't say something like "the beam will no longer hit point B, because it is deflected." That is irrelevant. The beams are diverging and overlapping, and what happens in point B depend only on the lengths of the paths of the light that hit point B, obviously. The same applies for the four mirror set up. It is stupid to say something like "the two contra going beams will no longer combine at the same point on the mirror." Some light will always hit at "the midpoint" of the combining mirror, and what happens in that point is only determined by the phase difference of the two light paths that actually hit that point. If the fringes shifts, it means that the phase difference changes, which only can mean that the length difference of the light paths have changed. The ballistic theory predicts no length difference of the light paths (measured in wavelengths) and thus no fringe shifts when the Sagnac ring rotates. But the fringes do shift when the Sagnac ring rotates. Sagnac falsifies the ballistic theory. No other conclusion is possible. > However, as I have pointed out, this is not the right BaTh analysis.

Two rays that leave the source at the same point but at 90 apart will be parallel but displaced sideways on arrival. This is not enough to cause a fringe shift because of the wavefront geometry. See, you have learnt something... >The same applies for the four mirror set up. >It is stupid to say something like "the two >contra going beams will no longer combine >at the same point on the mirror."

NO IT DOES NOT. MY THEORY EXPLAINS WHY. >But the fringes do shift when the Sagnac ring rotates. > >Sagnac falsifies the ballistic theory. > >No other conclusion is possible. Paul, the standard Sagnac argument against BaTh does not take into account all the relevant factors. I have explained previously what happens. When the apparatus rotates, the photon axes become misaligned with their velocity vectors...IN OPPOSITE SENSES. When they arrive at each mirror, the 'front end' hits the mirror at a different point from the 'back end'. Assuming pahots are many wavelengths long, this results in a small but significant path length difference as well as a reflection angle that is not the same as the incident angle.

It is MY discovery and you should feel very priviledges for being one of the first to read about it. >> However, as I have pointed out, this is not the right BaTh analysis.

The SR sagnac analysis requires that an absolute frame exists and that the rays move at c+/-v wrt the source at hte point of emission. SR proves its own postulate wrong.!!!!

Henry, for how much longer are you going to keep trying to use personal insults to cover up your lack of understanding of basic aspects of physics, such as how to express yourself in unambiguous terms? You still don't know what "frame" means or even that you need a transform to convert coordinates from one frame to another, you still don't know what "wrt" or "with respect to" means and you don't know how to define a frame. Ten years Henry, you were posting in s.p.r back in 1997 and you haven't even learnt the technical language in all that time.

Sorry for coming in on this discussion rather late. The last I bothered checking your views on Sagnac (some time last year), you had NO quantitative expression for the fringe displacement versus rotational velocity that was anywhere close to the experimental values. Among MANY issues that you had not resolved, was the simple question of whether light elastically "bounced" off mirrors at the same speed as the speed of the incident light, or alternatively, was re-radiated at c regardless of the speed of the incident rays. As I recall, the VB model that you developed assumed elastic bouncing, but elsewhere you seemed to adopt the viewpoint that light was emitted from mirrors, gratings, etc. at c relative to the mirrors, gratings, etc. Or was it vice-versa? You've never been clear on this. Regardless, what is your equation predicting the fringe displacement, and how do you justify your equation in terms of BaTh?
