"The speaker Joao Magueijo, is a Reader in Theoretical Physics at Imperial College, London and author of Faster Than the Speed of Light: The Story of a Scientific Speculation. He opened by explaining how Einstein's theory of relativity is the foundation of every other theory in modern physics and that the assumption that the speed of light is constant is the foundation of that theory. Thus a constant speed of light is embedded in all of modern physics and to propose a varying speed of light (VSL) is worse than swearing!It is like proposing a language without vowels."

"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 waysto change the speed of light without wrecking the whole thing too much."

The situation is unique. A whole branch of science is going to disappear just because the underlying axiom is false. And the falsehood is obvious:

Stationary light source; moving receiver:

(Website: )

The speed of the light pulses relative to the source is

c = df

where d is the distance between the pulses and f is the frequency measured by the source. The speed of the pulses relative to the receiver is

c'= df' > c

where f' > f is the frequency measured by the receiver.

Any relevant experiment (e.g. Michelson-Morley, Pound-Rebka, Doppler), if correctly performed and interpreted, proves VARIABLE speed of light as per Newton's theory:

John Norton: "The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

Wikipedia: "Emission theory, also called emitter theory or ballistic theoryof 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)."

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 inertialmass) suffices. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..."

R. V. Pound and J. L. Snider, Effect of Gravity on Gamma Radiation: "It is not our purpose here to enter into the many-sided discussion of the relationship between the effect under study and general relativity or energy conservation. It is to be noted that no strictly relativistic concepts are involved and the description of the effect as an "apparent weight" of photons issuggestive. The velocity difference predicted is identical to that which amaterial object would acquire in free fall for a time equal to the time offlight."

University of Illinois at Urbana-Champaign: "Consider a falling object. ITSSPEED 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. Consider a light beam that is travelling away from a gravitational field. Its frequency should shift to lower values.This is known as the gravitational red shift of light."

"Doppler effect - when an observer moves towards a stationary source. ...the velocity of the wave relative to the observer is faster than that when itis still."

"Let's say you, the observer, now move toward the source with velocity Vo. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: V'=V+Vo. The frequency of the wavesyou detect is higher, and is given by: f'=V'/λ=(V+Vo)/λ."

"Vo is the velocity of an observer moving towards the source. This velocityis 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 notalter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time."

Einstein "borrowed" his false constant-speed-of-light postulate from the ether theory:

Albert Einstein: "...I introduced the principle of the constancy of the velocity of light, which I borrowed from H. A. Lorentz's theory of the stationary luminiferous ether..."

Banesh Hoffmann, Relativity and Its Roots, p.92: "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. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether theone aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous."

Banesh Hoffmann clearly explains that, "without recourse to contracting lengths, local time, or Lorentz transformations", the Michelson-Morley experiment confirms Newton's variable speed of light (c'=c+v) and disproves the constant (independent of the speed of the emitter) speed of light (c'=c) posited by the ether theory and fatally "borrowed" by Einstein.

Einstein's false constant-speed-of-light postulate is essentially equivalent to Big Brother's 2+2=5. Arithmetic automatically becomes insane after 2+2=5 is introduced: no rational activity is possible. Exactly the same happened to fundamental physics in 1905:

"...Dr. Magueijo said. "We need to drop a postulate, perhaps the constancy of the speed of light."

In this case, somewhat paradoxically, dropping the falsehood and restoring 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 [Niayesh Afshordi and Joao Magueijo] had to find ways to change the speed of light without wrecking the whole thing too much."

Awful dilemma, isn't it? Afshordi and Magueijo are honest enough but still they beat about the bush a bit, so in this tweet

I tried to describe the dilemma as clearly as possible. The tweet received a like from... Niayesh Afshordi!
