The root of evil in physics is Einstein's constant-speed-of-light falsehood. Physicists know that. Some start telling the truth sometimes but then stop halfway. Modern physics is based on the falsehood and would collapse without it. In this regard, telling the truth is suicidal:

Joao Magueijo, Niayesh Afshordi: "The whole of physics is predicated on the constancy of the speed of light...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/article/8q87gk/light-spee

Doppler effect in light (moving observer):

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. Believing that c'=c is equivalent to believing that 2+2=5.

Einstein's Original Nonsense

Waves: Frequency and speed vary proportionally for a moving observer.

Particles: Frequency and speed vary proportionally for a moving observer.

Light in Einstein's relativity: Frequency varies but speed gloriously remains constant for a moving observer.

Einstein wrestled with his conscience "over a lengthy period of time, to the point of despair" before introducing the nonsense:

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/einstein/essay-einstein-

"The Doppler effect is common to all wave phenomena, including light, sound and water waves. When a wave source is moving towards an observer, the source appears to be catching up with the waves as it emits them. They therefore tend to bunch up in front of the source and arrive at the observer with a higher frequency." https://people.physics.anu.edu.au/~cms130/TEE/site/tee/learn
ing/doppler/doppler.html

Catching up means that the waves slow down relative to the moving wave source. Relative to a sufficiently fast moving source, the waves would be extremely slow. This is true for sound and water waves, but is it true for light? If not, why does the observer measure higher frequency when the light source is moving?

Answer: Because the speed of light varies with the speed of the source, as per Newton:

"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

VARIABLE wavelength of light https://youtu.be/3mJTRXCMU6o?t=77 is another root of evil in modern physics. It violates the principle of relativity. If the wavelength varied with the speed of the emitter, as in the above video, the emitter would measure the variations inside his spaceship and so would know his speed without looking outside.

The formula

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

tolerates two axioms:

Axiom 1: The speed of light is constant.

Axiom 2: The wavelength of light is constant (for a given emitter).

Axiom 1 killed physics.

Axiom 2 will resurrect it (if it's not too late). Corollaries:

Corollary 1: Any frequency shift entails (is caused by) a proportional speed-of-light shift.

Corollary 2: 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, as per Newton's theory.

Corollary 3: Spacetime and gravitational waves (ripples in spacetime) don't exist. LIGO's "discoveries" are fake.

Corollary 4: 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. Accordingly, there is no gravitational time dilation: Einstein's general relativity is absurd.

Corollary 5: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is not expanding.

There are two separate ideas to think about. First is the periodic motion of the electromagnetic radiation reflected or emitted into the environment. That depends on characteristics of the source such as material and temperature. The speed at which the EMr travels depends upon the medium. Secondly there is how the EMr is distributed in the environment, which can affect how/when it is intercepted. Point one concerns the EMr. the 'light itself' Point 2 concerns relation to the environment and observers, affecting the appearance of the light. 'Bunched up' waves intercepted will have the appearance of higher frequency. But the speed of the periodic EMr,'light ' is only effected by the nature of the environment. Not how it was distributed by the source nor what the observer does and sees.

Joao Magueijo's words below imply that, if the speed of light is variable (it is!), fundamental physics has been long dead - nowadays exists in a zombie state.

Dead physics means dying civilization. Are you killing the civilization, theoretical physicists?

"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." http://www.thegreatdebate.org.uk/VSLRevPrnt.html

"If there's one thing every schoolboy knows about Einstein and his theory of relativity, it is that the speed of light in vacuum is constant. No matter what the circumstances, light in vacuum travels at the same speed... The speed of light is the very keystone of physics, the seemingly sure foundation upon which every modern cosmological theory is built, the yardstick by which everything in the universe is measured. [...] The only aspect of the universe that didn't change was the speed of light. And ever since, the constancy of the speed of light has been woven into the very fabric of physics, into the way physics equations are written, even into the notation used. Nowadays, to "vary" the speed of light is not even a swear word: It is simply not present in the vocabulary of physics." https://www.amazon.com/Faster-Than-Speed-Light-Speculation/d

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

"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=mc², all basic predictions of special relativity. And all denied the possibility of establishing a well-defined border, common to all observers, capable of containing new quantum gravitational effects." Joao Magueijo, Faster Than the Speed of Light, p. 250 http://www.amazon.com/Faster-Than-Speed-Light-Speculation/dp
/0738205257

"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 here: http://pirsa.org/displayFlash.php?id=16060116

So Joao Magueijo discovered that special relativity is "the root of all the evil", broke the Lorentz invariance, adopted the Newtonian space-time, and teaches...general relativity:

hey to all,...

Quantum field theory in curved spacetime (QFTCS) is a viable approximation of the theory of quantum gravity when spacetime curvature is not significant on the Planck scale.

KV=tr (K ρV) − tr (K ρV0)=kc3ln(2)tevap)/16π2GM=SV=S (ρV│ρV0 )=S(ρV)- S(ρV0)=Tr (ρV(log (ρV)-log (ρV0)))=2πkRE/ℏc

The black holes entropic Information formula can calculate the entangled Hawking radiation down to the quantum system, describing black hole independently of the area law of the entropy of Bekenstein-Hawking. The black holes entropic information formula is equal to the universal bound originally found by Jacob Bekenstein. Which is equal by Casini’s work to the difference between the expectation value of the modular Hamiltonian in the excited state and the vacuum state, itself equal to the Von Neumann entropy. The ultraviolet divergences can be avoided by taking differences between quantities computed in an excited state and the same quantities computed in the vacuum state; this must be put in relation to Ryu and Takayanagi conjecture, a general formula for the fine-grained entropy of quantum systems coupled to gravity

The problem of attraction between mass taken the informations in the theory of loop s for example and in considering gravitons at slow energies to unify G c and h , the GR and the QM with the works of belenstein and hawking and even Vobson don t renormalize this QG ,m simply because the QG is newtonian between massive particles and that the lamda CDM model is the key to unify this QM. So yes the problem is philosophical consider the nature of the universe in its primordila, primary essence , and the main problem is to consider this GR like the primary essence and even in considering a BB which is hypothetical like if God had only created photons and after points or strings in this spacetime where we try to quantize the space.The hamiltonians in this reasoning shall not solve the infinite quantities.It is mainly how they quantize the spacetime the problem to eliminate these quantities infinite , they want to create finite quantities and that is why at slow energies they consider these gravitons like the quanta of gravitational waves.The main problem is philosophical about how we consider the volumes and geometries and topologies and the main origin of the universe with this spacetime. In fact what do the thinkers is to create their own solutions for these infinite quantities that we cannot renormalise, and they invent partitions and models in changing the properties of the spacetime . The problem is that is we take this GR without modifying it , they cannot solvge the problem and it is I repeat a philosophjical choice, that does not mean that it is true.

the degrees of freedom of even the fluctuations at this planck scale for the vacuum or others are not the problem, the philosophy of origin is the problem . The BHs and works of Hawking, the loop quantum gravity , the GR are referentials with speficic chosen laws and after they play different partitions to unify the GR and the QM for this QG. Now considering the informations and their lost or not , their mass or not are not the problem for this quantization of this QG, because if the QM is not due to this GR simply and that the QFT has a deeper logic, that implies that they trun in round in this philosophical prison. It is mainly how we interpret the philosophical origin of the nunivefrse, the spacetime and here in your case the informations. We arrive at a main problem of this GR considering the singularities and this quantum gravity,The problem is that the majority of thinkers try to modify postulates of this newtonian mechanics or this GR and in logic we cannot , that said the predictions philosophical can be harmonised with these deeper parameters to add at all scales, quantum and cosmological.

To be frank , I don t understand how is it possible that the majority of thinkers since the works of Einstein are blocked like this in this GR and SR like if it was the only one truth for the universe, like if god or the universe had created only photons and this spacetime of the GR and that with the mass energy equivalence of einstein , god plays at guitar with the fields, oscillations,...
