Default Variable Speed of Light: Just around the Corner

Paul Davies: "Was Einstein wrong? The idea of a variable speed of light, championed by an angry young scientist, could one day topple Einstein's theory of relativity. Einstein's famous equation E=mc^2 is the only scientific formula known to just about everyone. The "c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics.. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this mean the next Great Revolution in Science is just around the corner?" http://www.prospectmagazine.co.uk/ma...einsteinwrong/

The "maverick scientists":

Joao Magueijo, Niayesh Afshordi, Stephon Alexander: "So we have broken fundamentally this Lorentz invariance which equates space and time [...] It's the other postulate of relativity, that of constancy of c, that has to give way..." https://youtu.be/kbHBBtsrU1g?t=1431

"You want to go back to a notion of space-time that preceded the 20th century, and it wants to ignore the essential lessons about space-time that the 20th century has taught us." Joao Magueijo: "Yes, that's right. So it's nouveau-Newtonian." At 53:31 he http://pirsa.org/displayFlash.php?id=16060116

Obviously variable (Newtonian) speed of light:

https://www.youtube.com/watch?v=bg7O4rtlwEE

The speed of the light pulses as measured by the stationary observer is

c = df

where d is the distance between the pulses and f is the frequency measured by the stationary observer. The speed of the pulses as measured by the moving observer is

c'= df' c

where f' f is the frequency measured by the moving observer.

If judged by their speed alone, photons are Newtonian particles. The speed of light VARIES, both in the presence and in the absence of gravity, just as does the speed of ordinary projectiles (e.g. bullets):

"Emission theory, also called Emitter theory or ballistic theory of light, was a competing theory for the special theory of relativity, explaining the results of the Michelson–Morley experiment of 1887. [...] The name most often associated with emission theory is Isaac Newton. In his corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v)." https://en.wikipedia.org/wiki/Emission_theory

"To see why a deflection of light would be expected, consider Figure 2-17, which shows a beam of light entering an accelerating compartment. Successive positions of the compartment are shown at equal time intervals. Because the compartment is accelerating, the distance it moves in each time interval increases with time. The path of the beam of light, as observed from inside the compartment, is therefore a parabola. But according to the equivalence principle, there is no way to distinguish between an accelerating compartment and one with uniform velocity in a uniform gravitational field. We conclude, therefore, that A BEAM OF LIGHT WILL ACCELERATE IN A GRAVITATIONAL FIELD AS DO OBJECTS WITH REST MASS. For example, near the surface of Earth light will fall with acceleration 9.8 m/s^2." http://web.pdx.edu/~pmoeck/books/Tipler_Llewellyn.pdf

Banesh Hoffmann, Einstein's collaborator, admits that, originally ("without recourse to contracting lengths, local time, or Lorentz transformations"), the Michelson-Morley experiment directly proved Newton's variable speed of light and disproved the constant speed of light:

"Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether." Banesh Hoffmann, Relativity and Its Roots, p.92 https://www.amazon.com/Relativity-It.../dp/0486406768

John Stachel: "But this seems to be nonsense. How can it happen that the speed of light relative to an observer cannot be increased or decreased if that observer moves towards or away from a light beam? Einstein states that he wrestled with this problem over a lengthy period of time, to the point of despair." http://www.aip.org/history/exhibits/...relativity.htm

"Seems to be nonsense" is a red herring. Einstein's 1905 constant-speed-of-light axiom is OBVIOUS NONSENSE, but an all-powerful ideology forces scientists to believe the opposite of what they see. Einsteinians clearly see that the frequency and the speed of the light pulses vary proportionally for the moving observer in Doppler

https://youtube.com/watch?v=bg7O4rtlwEE

but believe that only the frequency varies - the speed of the pulses gloriously remains constant. Such a behaviour was explained long time ago:

Ignatius of Loyola: "We should always be prepared so as never to err to believe that what I see as white is black, if the hierarchical Church defines it thus."

The formula

(frequency) = (speed of light) / (wavelength)

says that the speed of light is constant as per Einstein

if and only if

ANY frequency shift entails (is caused by) an inversely proportional wavelength shift.

The consequent, "any frequency shift entails (is caused by) an inversely proportional wavelength shift", is obviously false, even absurd:

Doppler effect - when an observer moves toward a stationary source https://www.youtube.com/watch?v=bg7O4rtlwEE

"Thus, the moving observer sees a wave possessing the same wavelength [...] but a different frequency [...] to that seen by the stationary observer." http://farside.ph.utexas.edu/teachin...ml/node41.html

Accordingly, the antecedent, "the speed of light is constant as per Einstein", is false as well.

Fundamental physics was killed in 1905. The killer ("the root of all the evil") was special relativity, or, more precisely, Einstein's 1905 false constant-speed-of-light postulate:

"Lee [Smolin] and I discussed these paradoxes at great length for many months, starting in January 2001. We would meet in cafés in South Kensington or Holland Park to mull over the problem. THE ROOT OF ALL THE EVIL WAS CLEARLY SPECIAL RELATIVITY. All these paradoxes resulted from well known effects such as length contraction, time dilation, or E=mc^2, all basic predictions of special relativity." Joao Magueijo, Faster Than the Speed of Light, p. 250 http://www.amazon.com/Faster-Than-Sp.../dp/0738205257

"[George] Ellis is up against one of the most successful theories in physics: special relativity. It revealed that there's no such thing as objective simultaneity. [...] Rescuing an objective "now" is a daunting task." https://www.newscientist.com/article...wards-in-time/

"...Dr. Magueijo said. "We need to drop a postulate, perhaps the constancy of the speed of light." http://www.nytimes.com/2002/12/31/sc...-relative.html

Joao Magueijo, Niayesh Afshordi, Stephon Alexander: "So we have broken fundamentally this Lorentz invariance which equates space and time [...] It is the other postulate of relativity, that of constancy of c, that has to give way..." https://youtu.be/kbHBBtsrU1g?t=1431

As the above quotations show, physicists do try to tell the truth sometimes but there is a problem. The farce called "fundamental physics" is entirely predicated on Einstein's constant-speed-of-light falsehood and will collapse without it. In this regard, telling the truth is suicidal:

"The whole of physics is predicated on the constancy of the speed of light," Joao Magueijo, a cosmologist at Imperial College London and pioneer of the theory of variable light speed, told Motherboard. "So we had to find ways to change the speed of light without wrecking the whole thing too much." https://motherboard.vice.com/en_us/a...t-speed-slowed
