Default VARIABLE SPEED OF LIGHT OR VARIABLE WAVELENGTH?

http://physics.ucsd.edu/students/cou...ecture5-11.pdf
"Doppler Shift. As long as the velocity of the observer, v, is much smaller than the speed of light, c, (for the case of sound waves much smaller than the speed of sound) then the expression that we derived is a very good approximation. Taking into account v may be in the opposite direction: f'=f(1±v/c). At this point you might ask why the shift in direction from the discussion of the equivalence principle. Soon, as we shall see, we can put this together with the equivalence principle to derive the gravitational redshift of light! In 1960 Pound and Rebka and later, 1965, with an improved version Pound and Snider measured the gravitational redshift of light using the Harvard tower, h=22.6m. From the equivalence principle, at the instant the light is emitted from the transmitter, only a freely falling observer will measure the same value of f that was emitted by the transmitter. But the stationary receiver is not free falling. During the time it takes light to travel to the top of the tower, t=h/c, the receiver is traveling at a velocity, v=gt, away from a free falling receiver. Hence the measured frequency is: f'=f(1-v/c)=f(1-gh/c^2)."

There are only two sets of values for the measured speed of light (c') and the measured wavelength (L'):

(A) c' = c-v = c(1-gh/c^2) ; L' = L

(B) c' = c ; L' = L/(1-v/c) = L/(1-gh/c^2)

The equations (A) are fundamental in Newton's emission theory of light (many Einsteinians teach them implicitly). They obey a principle valid for all waves - the motion of the observer cannot change the wavelength but does change the measured speed of the waves.

The equations (B) are so absurd that even Einsteinians never mention them. Yet the absurd equations are crucial for the survival of Divine Albert's Divine Theory.

Default VARIABLE SPEED OF LIGHT OR VARIABLE WAVELENGTH?

Variable speed of light or variable wavelength? Variable speed of light of course:

http://a-levelphysicstutor.com/wav-doppler.php
"vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. (...) The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time."

http://www.expo-db.be/ExposPrecedent...%20Doppler.pdf
"La variation de la fréquence observée lorsqu'il y a mouvement relatif entre la source et l'observateur est appelée effet Doppler. (...) 6. Source immobile - Observateur en mouvement: La distance entre les crêtes, la longueur d'onde lambda ne change pas. Mais la vitesse des crêtes par rapport à l'observateur change !"

http://www.usna.edu/Users/physics/mu...plerEffect.pdf
Carl Mungan: "Consider the case where the observer moves toward the source. In this case, the observer is rushing head-long into the wavefronts... (....) In fact, the wave speed is simply increased by the observer speed, as we can see by jumping into the observer's frame of reference."

http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf
Roger Barlow, Professor of Particle Physics: "Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/(lambda) waves pass a fixed point. A moving point adds another vt/(lambda). So f'=(c+v)/(lambda)."

http://www.cmmp.ucl.ac.uk/~ahh/teach...24n/lect19.pdf
Tony Harker, University College London: "If the observer moves with a speed Vo away from the source (...), then in a time t the number of waves which reach the observer are those in a distance (c-Vo)t, so the number of waves observed is (c-Vo)t/lambda, giving an observed frequency f'=f((c-Vo)/c) when the observer is moving away from the source at a speed Vo."

http://www.einstein-online.info/spotlights/doppler
Albert Einstein Institute: "As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses [that is, the speed of light as measured by the receiver is (4/3)c]."

Default VARIABLE SPEED OF LIGHT OR VARIABLE WAVELENGTH?

Variable speed of light or variable wavelength? Variable speed of light of course, as predicted by Newton's emission theory of light:

http://www.youtube.com/watch?v=ixhczNygcWo
"Relativity 3 - gravity and light"

http://online.physics.uiuc.edu/cours...re13/L13r.html
University of Illinois at Urbana-Champaign: "Consider a falling object. ITS SPEED INCREASES AS IT IS FALLING. Hence, if we were to associate a frequency with that object the frequency should increase accordingly as it falls to earth. Because of the equivalence between gravitational and inertial mass, WE SHOULD OBSERVE THE SAME EFFECT FOR LIGHT. So lets shine a light beam from the top of a very tall building. If we can measure the frequency shift as the light beam descends the building, we should be able to discern how gravity affects a falling light beam. This was done by Pound and Rebka in 1960. They shone a light from the top of the Jefferson tower at Harvard and measured the frequency shift. The frequency shift was tiny but in agreement with the theoretical prediction."

http://www.damtp.cam.ac.uk/user/hsr1...notes12_02.pdf
Harvey Reall, University of Cambridge: "...light falls in the gravitational field in exactly the same way as a massive test particle."

http://sethi.lamar.edu/bahrim-cristi...t-lens_PPT.pdf
Dr. Cristian Bahrim: "If we accept the principle of equivalence, we must also accept that light falls in a gravitational field with the same acceleration as material bodies."

http://www.einstein-online.info/spot...t_white_dwarfs
Albert Einstein Institute: "One of the three classical tests for general relativity is the gravitational redshift of light or other forms of electromagnetic radiation. However, in contrast to the other two tests - the gravitational deflection of light and the relativistic perihelion shift -, you do not need general relativity to derive the correct prediction for the gravitational redshift. A combination of Newtonian gravity, a particle theory of light, and the weak equivalence principle (gravitating mass equals inertial mass) suffices."

http://arxiv.org/ftp/gr-qc/papers/0403/0403082.pdf
The Gravitational Red-Shift, R.F.Evans and J.Dunning-Davies, Department of Physics, University of Hull: "Attention is drawn to the fact that the well-known expression for the red-shift of spectral lines due to a gravitational field may be derived with no recourse to the theory of general relativity. This raises grave doubts over the inclusion of the measurement of this gravitational red-shift in the list of crucial tests of the theory of general relativity. (...) In truth, it would seem that the result for the red-shift of spectral lines due to the action of a gravitational field has nothing specifically to do with the theory of general relativity. It is a result which draws on more modern results due to such as Planck and Poincaré, but, apart from those, is deduced from notions of Newtonian mechanics alone."

Default VARIABLE SPEED OF LIGHT OR VARIABLE WAVELENGTH?

Time to remember Bryan Wallace:

https://groups.google.com/d/topic/sc...xH8/discussion
Bryan Wallace 1994: "On page 4 of the September 19, 1993 issue of the Sunday Newspaper PARADE MAGAZINE, Carl Sagan wrote: "It would be demoralizing to learn that our science is medieval." But by the standards of the next few centuries, at least some of our present science will be considered medieval, extraterrestrials or no extraterrestrials. At the very top of the pile of medieval theories will be Einstein's relativity theory that starts with the postulate that for some undefined abstract mystic reason, the speed of light is the same for all observers, no matter how fast they or an observed object travels!"

http://www.fileden.com/files/2008/8/...9-p361-367.pdf
RADAR TESTING OF THE RELATIVE VELOCITY OF LIGHT IN SPACE, Bryan G. Wallace, Spectroscopy Letters, 1969, pages 361-367, ABSTRACT: "Published interplanetary radar data presents evidence that the relative velocity of light in space is c+v and not c." INTRODUCTION: "There are three main theories about the relativity velocity of light in space. The Newtonian corpuscular theory is relativistic in the Galilean sense and postulates that the velocity is c+v relative to the observer. The ether theory postulates that the velocity is c relative to the ether. The Einstein theory postulates that the velocity is c relative to the observer. The Michelson-Morley experiment presents evidence against the ether theory and for the c+v theory. The c theory explains the results of this experiment by postulating ad hoc properties of space and time..."

http://www.ekkehard-friebe.de/wallace.htm
Bryan Wallace: "Because many of the dominant theories of our time do not follow the rules of science, they should more properly be labeled pseudoscience. The people who tend to believe more in theories than in the scientific method of testing theories, and who ignore the evidence against the theories they believe in, should be considered pseudoscientists and not true scientists. To the extent that the professed beliefs are based on the desire for status, wealth, or political reasons, these people are scientific prostitutes. (...) Einstein's special relativity theory with his second postulate that the speed of light in space is constant is the linchpin that holds the whole range of modern physics theories together. Shatter this postulate, and modern physics becomes an elaborate farce! (...) The speed of light is c+v. (...) I expect that the scientists of the future will consider the dominant abstract physics theories of our time in much the same light as we now consider the Medieval theories of how many angels can dance on the head of a pin or that the Earth stands still and the Universe moves around it." [Note: Bryan Wallace wrote "The Farce of Physics" on his deathbed hence some imperfections in the text!]
