Default Variable Speed of Light: the Next Great Revolution in Science

Paul Davies 2003: "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 revolution is no longer around the corner - it is he

"So we have broken fundamentally this Lorentz invariance which equates space and time..." 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 53:29 he http://pirsa.org/displayFlash.php?id=16060116

The problem is that the truth - variable speed of light, as per Newton - will completely destroy fundamental physics. Things will have to restart from scratch:

"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." https://motherboard.vice.com/en_us/a...t-speed-slowed

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

https://twitter.com/pentcho_valev/st...89439147859970

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

The truth:

Default Variable Speed of Light: the Next Great Revolution in Science

Newton's variable speed of light

https://pbs.twimg.com/media/DzyndPsXgAEWeW2.png

is correct, but there is a more fundamental axiom from which future physics can start. Consider the standard interpretation of Doppler effect in light (moving emitter):

Stephen Hawking, "A Brief History of Time", Chapter 3: "Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary." http://www.fisica.net/relatividade/s...ry_of_time.pdf

The conclusion that the wavelength decreases in front of the moving source is based on the analogy with e.g. water waves, but this analogy is incorrect. For water waves, the wavelength decreases in front of the moving source because the speed of the waves relative to the source decreases (and can even become zero). The moving source is CHASING the emitted crest - that is the reason why, when the next crest is emitted, the distance between the two crests is smaller than when the source is stationary. As chasing becomes faster and faster, the distance between crests approaches zero.

In the case of light waves there is no chasing. No matter how fast the source is moving, the speed of the emitted crest relative to the source remains invariable (does not decrease, as in the case of water waves). For that reason, when the next crest is emitted, the distance between the two crests is INVARIABLE - the same as when the source is stationary.

In future physics, Einstein's false axiom

"Speed of light is invariable"

will be replaced with the correct axiom

"Wavelength of light is invariable".

So the formula

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

will mean that ANY frequency shift entails (is caused by) a speed-of-light shift.

Three valid (truthfulness of the premises guarantees truthfulness of the conclusion) arguments:

Premise 1: The wavelength of light is invariable.

Premise 2: The formula (frequency) = (speed of light)/(wavelength) is correct.

Conclusion 1: If the emitter and the observer (receiver) travel towards each other with relative speed v, the speed of light as measured by the observer is c' = c+v (Newton's variable speed of light is a consequence of the new axiom).

Conclusion 2: Light falls in a gravitational field with the same acceleration as ordinary falling bodies - near Earth's surface the accelerations of falling photons is g = 9.8 m/s^2. Gravitational time dilation does not exist - Einstein's general relativity is absurd.

Conclusion 3: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is STATIC, not expanding.

The new axiom

"Wavelength of light is invariable",

designed to replace Einstein's false axiom

"Speed of light is invariable",

is more than justified as one considers light falling in a gravitational field. The quotations below clearly show that the frequency and the speed of falling light vary proportionally, as predicted by Newton's theory. This means that, in accordance with the formula (frequency)=(speed of light)/(wavelength), the wavelength is INVARIABLE:

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. [...] The gravitational redshift was first measured on earth in 1960-65 by Pound, Rebka, and Snider at Harvard University..." http://www.einstein-online.info/spot...te_dwarfs.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. 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." https://courses.physics.illinois.edu...re13/L13r.html

"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
