That is also the catch-up ratio so the bunching is asymptotic to reducing the spacing by 0.1% at most. Think of your findings on the pulsars if you have trouble following the logic. That's only the VDoppler component. No, it is TDoppler. How many times do I have to correct you on that? George, I know TDoppler is the overall cause. When I said, "That's only the VDoppler component", I was implying that the VDoppler component was greater than the ADoppler component, which can be ignored. OK, in that case we agree. Please try to say TDoppler if that's what you mean, it just wastes a lot of time clearing this up each time. No it doesn't George. You are telling little fibs again. The photons keep moving at c+v for a lot longer than the 'ends of each photon'. It's all so simple really. Nicely put, the beginning, end and middle of each photon move at (c+v)/10000 while the mean speed of the photon is (c+v). No you've gotten it all wrong again George. I think you meant c+(v/10000)....but it doesn't even do that for very long. I meant (c+v)/10000 but c+(v/10000) is also possible, your theory is self-contradictory which means if I assume c+v I can use it to prove (c+v)/10000 or vice versa or maybe that black is white. The trouble with self-contradictory theories is that they produce results that violate their own postulates so the number you get depends on what route you take. See, George, you have been missing the point all along. What are you talking about? What I said was correct. The whole photon settles down to a fixed length that is shorter than when it was emitted by L'=Le(1-Ka), where a is the radial acceleration of the source at the point of emission. Henry, there is only _one_ equation for the speed in your theory and it applies to _all_ parts so K=1. No you've gotten it all wrong again George. No Henry, you just don't understand how physical laws can be used as tools so that one assumption, say c+v, leads to other conclusions like the Doppler equation by purely mathematical means. What a strange this to say! Not really, K=1 can be derived purely mathematically and you are ignoring that which produces your inconsistency. This is just the procedure I'm following in relation to star brightness curves and the BaTh. No, you are plucking a value of K out of thin air instead of deriving it using Fourier analysis (or some other equivalent approach, there's more than one way). You claimed elsewhere you knew how to use a Fourier transform (which I doubt but never mind) so just apply it to a pulse modulated carrier and see what you get if you apply your Doppler equation to the components. Reverse transform the frequency shifted elements to get the received waveform as usual. An individual photon has intrinsic properties that are not part of the group bunching process. Hiwever it is still subject to ADoppler, in a small way. It's all so simple if you open up your mind George. Of course I can believe in anything if I allow for fantasies but raw maths rules out your handwaving crap and this is a science group, not sci-fi. You like to model the maths to suit yourself. You don't "model the maths" Henry, you use maths to model the real world. My theory is perfectly mathematically sound. No, it is mathematically self-contradictory, I have explained why dozens of times. Do a Fourier transform and see for yourself. An EM FoR is ... a mathematical coordinate system with no physical existence being used to defines locations and time of EM phenomena. It ''''loosely''''' defines EM speed in that FoR No, I can describe the speed of light in my office using a coordinate system centred on the barycentre of the Bullet Cluster, but the cluster does not define the speed in any way whatsoever. OK 'defines' wasn't the best word. "Describes" or "labels" would be better but the key point is that the FoR has no physical existence. In an EM FoR, light speed will TEND TOWARDS c/n wrt the frame's 'EM centre'. c/n wrt the material which produces the refractive index n as measured using a frame of reference in which that material is at rest would probably be the clearest way to state that. The latter is another Wilsonian pseudo-geometric term that describes a kind of average influence exerted by all the 'substance' inside the frame (ie., matter and fields) on all light originating in or passing through it. I trust that is now settled. Just say 'matter' when you mean it and the problem goes away. For other angles the equation is N(lambda= D[sin(theta)/(c+u)-sin(phi)/(c+v)] Yes, I was assuming the first order result in my other replies too. In general the BaTh grating equation is: N * lambda_r = D * sin(phi) Why do you want to use lamba_r? Henry, do you understand what it means to put a variable on the left hand side of an equation? Perhaps I should have written it as: lambda_r = D * sin(phi) / N but I kept it similar to yours to help you follow. I am only "using" D and phi, both of which I can measure. lambda_r is the result. You don't know what its value is unless you know the reflected light speed exactly. ..but you know lambda_i because it's is absolute and universal. Wrong, measuring D, the grating spacing, and phi, the deflection angle, tells me lambda_r. I know nothing more than that. You certainly don't know lambda_i because that depends on the source, gravitational redshift, cosmogical redshift, speed equalisation, material conditions and magnetic fields in the source and so on. George, you obviously didn't follow my diagram. It describes BaTh not aether theory. Have another look... I didn't mention an aether. I'm fairly happy with your diagram. The criterion is TIME not distance. My 'lambda' is your Lambda_i. The time taken for ray 2 reach the grating after the previous wavecrest (front) from ray 1 has been reflected to the end of line 'x' is Lambda_i/(c+v). The time for ray 1's reflection to travel distance 'x' is Dsin(phi)/(c+u) ...these two times are equal. The time for ray 1 is the distance from ruling 1 to the point on the screen divided by the speed of ray 1. The time for ray 2 is the distance from ruling 2 to the same point on the screen divided by the speed of ray 2. You are assuming that the speed of the two rays is the same, i.e. u1 = u2. That may not be the case if the deflection angles differ as might be the case if the screen were very close to the grating, however, if we assume the rays are close to parallel then the speeds should be the same and rays arrive in phase if the difference in distance is an exact multiple of the reflected wavelength. That gives you the grating equation: lambda_r = D * sin(phi) / N get it now? I always did, I derived the above directly from your first attempt. The bottom line is that a manufacturer ould make a grating with an attached protractor and mark the scale with Angstroms instead of degrees and you could read off the reflected wavelength. He cannot mark it in nanoseconds for you to read a time and the reading in Angstroms is _not_ the incident wavelength since BaTh allows for a change of speed on reflection. You are the one who still isn't getting it even though you wrote the equation yourself. Exactly, the only evidence you have from any actual obervations is for VDopppler alone. That's what I have been pointing out all along. All the luminosity variations are known to have other mundane explanations and there is _no_ evidence for the existence of ADoppler whatsoever. No George, you aren't even trying to pass the test. ... Correct, that is basic logic. If you want to prove ADoppler exists you have to show that a result could _not_ be explained by an alternative. The luminosity curves you have suggested can be explained by intrinsic variability in Cepheids and by eclipses in contact binaries so you have no proof. ...and it is pure coincidence that the shape of just about all variable star curve just happens to match the BaTh prediction for simple orbiting stars? It doesn't, you admitted already there are harmonics you can't explain. However, that's an aside. The point is that it _could_ be coincidence and your task is to provide _proof_ that coincidence cannot explain it. Consider what would happen if we found an eclipsing binary where the velocity curves were at their maxima during the eclipse and were perfect sine waves. That would show the orbits were circular and the phase would indicate ADoppler. That's what you need. Bottom line is that you have offerred no scientific proof at all for the existence of ADoppler. Some of us physicists can put two and two together George.... ![]() Putting coincidences together is what laymen do Henry, you could never be a physicist. .... The movement BETWEEN photons continues for some time. Then each photon is moving at a mean different speed from the speed of its parts which is nonsense, and if you do a Fourier analysis you will find the modulation of any wave will move at (c+v)/K when BaTh starts from the assumption that it is (c+v). The result is self- contradictory and therefore self-falsifying. It isn't nonsense, George. It is nonsense Henry, do a Fourier analysis if you doubt me, you claimed you knew how to do that. It is merely the mechanism of 'bunching', which you illustrated yourself. The bunching is valid and produces ADopppler as well as VDoppler, but you will find it must apply at the same level to pulses and cycles of a sine wave if you use a Fourier analysis. That means K=1. I keep telling you George, the intrinsic properties of individual photons must be treated differently from those of the main 'bunching wave'. And I keep telling you that if you do a Fourier analysis as you claim you can, you will find that is impossible. .... Here you go again...applying some kind of classical wave theory to light particles. BaTh as you have described it is a classical wave theory. The group movenent of photons IS ballistic. Yes, and ballistics is classical. ...not 'classical wave'.... It is "classical" because it treats the universe as deterministic and being able to be exactly calculated using some combination of waves, particles and so on. Post-classical theory treats all events as being definable only in terms of probabilities and the classical laws emerge only through the statistics of large numbers of individual events. Whether it uses waves or ballistics is neither here nor there but your current formulation simply uses classical waves with a modified speed equation. Perhaps it would be clearer if you wrote down what you think is the BaTh equation for a propagating wave. What happens inside individual photons is also ballistic but to a much smaller and limited extent. Your "photons" are classical wavetrains, not point particles. My best model is the 'serated bullet' one, where the serations represent a 'standing wave' or a helical path carved in space by something that rotates as it moves. It doesn't model the BaTh equations, the best match I could get was the coil of wire moving along its axis. The back can catch and pass through the front and the speed of each part is independent of all other parts. That accurately reflects the BaTh maths though it is harder to visualise. Nope lambda_r = D * sin(phi) Incident light speed is prsent in 'lambda_r', George. lambda_r has units of length Henry, don't be an idiot. Lambda_r=lambda_i.(c+u/(c+v)), assuming light leaves the grating at c+u. lambda_r is what is measured by the grating. That may imply other things _IF_ you make _ASSUMPTIONS_ but lambda_r is the only quantity that is actually measured. see above. I didn't think I would have to teach YOU geometry George. We always agreed the geometry Henry. I didn't think I would have to teach you algebra Henry but it seems I do. Otherwise it is the same as the classical one. It measures reflected wavelength specifically but otherwise is the same as the classical equation. No it doesn't. Yes it does Henry, your previous guesses were wrong. It measures the time ... D * sin(phi) / N does not have units of time Henry. OK.... strictly speaking, it combines TIME and ABSOLUTE incoming wavelength with the observed diffraction angle to calculate relative source speed . No Henry, strictly speaking the angle depends _only_ on the reflected wavelength. It does _not_ measure the incident wavelength. You might try to infer that but you can only do so by making an _assumption_ about the change of speed on reflection. That's OK. There is still a carrier frequency and a signal frequency. Actually no, there is just a carrier and a 'local oscillator' but the key point is that the same mixing technique works as well for light as it does for audio and RF. Some people have recently claimed that this is true. This has been the basis of instruments for many years, you are way out of date again. My understanding is that only quite recently has light been mixed with very short microwaves to create observable beats. Laser combs have been in use for many years. I couldn't say how long but I heard of their use a long time ago. It still doesn't tell us much about photon 'frequency' because beating is really a 'wavelength based' phenomenon. You miss the point, beating is a linear effect based on addition of waves, the envelope exhibits the difference frequecy but if you analyse the composite with Fourier you only have the original frequencies. Heterodyning produces actual signal power at the sum and difference frequencies which requires _multiplication_ of the source waves. It is exactly the same technique used in radio receivers and means that light behaves exactly the same as radio. Anything I can do with a CW 1MHz transmitter can in theory also be done with a mono-mode laser beam given fast enough components Same as for RF of course, a stream of phase-related photons. Why not a periodic variation in photon density? Variations in flux also apply to both. How does one 'phase relate' photons anyway? By making all the electrons in an antenna move in the same direction at the same time, or by getting one photon to prompt the emission of another in phase in a laser. Doesn't each electron emit a stream of photons as it accelerates George? Since all the electrons move together under the influence of the signal applied to the antenna, they emit in phase. I don't agree. I say they each emit randomly but the RATE at which they emit is governed by the signal. No, the rate of arrival is just the intensity for light or the carrier power for RF. The carrier 'frequency' relates to varying photon density. No, it is intrinsic, a single photon still gets deflected by a grating by the same amount as the stream from which it was taken. Come on!..., you don't know what happens to photons in a radio wave. Exactly the same as light Henry. Well, I suppose their are plenty of individual 'RF wavelength' photons produced by thermal radiation and weak molecular bond transitions. ....but they don't make a radio wave. They do, thermal radiation can be detected as microwaves but it has a broadband spectrum because the photons are not phase related. Photons in the visible light region and higher can be detected individually, as you pointed out. Lots of similar photons all going in the same direction make a maser or laser beam. Question: What happens to individual photons inside a maser cavity? They bounce off the ends and have a small probability of escaping. As they pass some atoms, the promt the emission of additional photons in phase. .... Because individual photons are particle-like and what happens inside them doesn't influence the bunching process at all. Your model is classical waves, not point particles, but you don't even need that, just apply Fourier to the macroscopic sum of the photons which is a clasical wave travelling at c+v. If I were to assume that intrinsic photon oscillations interact, a fourier combination would produce either white light or complete destructive interference...I'm not sure which. It can produce either constructive or destructive interference. White light is broadband with a uniform spread of intrinsic frequency and uncorrelated phases. George, think of a pure sinusoidal RF signal. I say the observed wave effect is just a result of photon density variation...or 'bunching'. Visible light on the other hand is generally not like that at all... but consists of identical photons whose energies add together to form 'beam intensity'. Visible light and radio are known to be the same thing differing only in the frequency range. The fact that we can multiple laser combs with incident light or with microwave signals using the old heterodyne technique proves that. Since each photon carries the same energy, bunching gives changes of intensity. If what you say were true, a single photon wouldn't have any preferred deflection angle when hitting a grating but in fact in a low rate stream from a monochromatic source all the photons get deflected by the same amount even when the arrival rate is random. See the video or stills I cited. In my model, an EM beam of a particular wavelength can be produced in two quite different ways. It can be the result of either lots of identical photons or it can reflect the bunching pattern formed in groups of random photons all traveling in the same direction. Consider the electron radiation from an RF antenna again. Each electron experiences varying acceleration as it moves up and down the antenna...but all are linked in phase. The radiation from each electron must be entirely random but the overall flux density of radiation is still controlled by the signal. Facts: 1) the "flux density" is controlled by the voltage fed to the antenna, not the frequency. 2) Each photon has the same frequency as the frequency of the AC fed to the antenna. The individual photons don't have to be 'phase-linked' in any way. Then call it that, "matter" is an appropriate term. It isn't just 'matter'. What is matter anyway? Then call it the aether, whatever, "frame of reference" has an entirely different meaning. Not my EM FoR. "Frame of reference" is purely mathematical, you are talking about a combination of matter and an aether. Well I wont dwell on this ... Nor will I if you stop getting it wrong, it is only jargon, not physics. You're unusually stubborn today George. You arethe one continually causing confusion by insisting on being wrong Henry, why do you stubbornly persist in saying "frame of reference" when you know it means something completely different to what you are trying to describe? I have now provided a clearer definition. The accepted terms for what you are describing are matter and/or an aether. Frame of reference is the coordiante scheme used to describe the motion of the matter and the flow of the aether. Frame of reference is mathematical only, matter is what you mean. Not this one...it's physical... Still stubbornly insisting on being wrong Henry, why don't you grow up a bit. I have now provided a clearer definition. You don't need a dfinition, both concepts have existing terms to describe them. Stick with those accepted terms Henry, I'll continue to point out where you get them wrong for the benefit of lurkers who haven't seen this. Also the reflected angle will not be exactly the incident one. Wrong again, since incident and reflected speeds are the same, the angles are also the same. But the reflected and incident speeds are NOT the same.. See above, both are c. There is a subtle problem with reflection angles that we haven't considered at all. I will get onto this soon. No, no problem at all. The ratio of the angles depends on the ratio of the speeds and since the speeds are the same, the angles are the same. Have another think about it George. No need, we discussed this to death three years ago and you discovered I was right, the diagram is still there. We ignored a vital piece of information. George, if you shoot from a moving car at an object lying at 45 degrees, what is the direction of the bullet's CENTRAL AXIS when it hits? I don't care, the thing measured in Sagnac is the time of flight of the bullet. ... If the object is also moving at your speed but perpendicularly away from the road, how does that affect the angle at which the bullet will bounce of the object (assuming specularly). Do you mean vertically up from the Sagnac turntable? It would simply go over the top of the detector. I'm not sure I understand your question. Photons are not 'little round balls'. I think you will also find that the equation governing fringe shift turns out to be similar to the aether theory one. Nope, ballistic theory says there should be no fringe shift whatsoever as we proved with your diagram and my algebra: http://www.briar.demon.co.uk/Henri/sagnac.gif Remember that? You drew it and I just fixed a minor error. The original might still be on your site somewhere and the algebra is on Google. it's wrong. You drew it, it is correct and you agreed the algebra. Repeat the analysis if you wish, it's only maths so you will get the same result. It's a lot more complicated. You drew it and it correctly shows the full story as described by ballistic theory. You also checked and agreed the equations I worte relating to it which were in all honesty quite trivial. They say there should be no fringe shift which is exactly what we expect from ballistic theory, it predicts no shift. Essentially what happens is that one beam moves around the ring at c+v/root2 and the other at c-v/root2 (wrt the non-rotating frame)... The small difference in path length doesn't compensate for the difference in travel times.. Do the algebra Henry, we showed the compensation was exact including the "root2" factor. Yes, I'm aware of what we did before. Good, I can't be bothered digging it up again. George |
