VARIABLE wavelength of light

contradicts the principle of relativity: By measuring the varying wavelength, inside his spaceship, the emitter would know his speed without looking outside. The wavelength of light is INVARIABLE.

INVARIABLE wavelength entails VARIABLE speed of light 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

Invariable speed of light, variable wavelength: Einstein's false paradigm that killed physics (made it insane).

Variable (as per Newton) speed of light, invariable wavelength: The new paradigm that could resurrect physics (if it's not too late).

I have developed the idea in a series of tweets he https://twitter.com/pentcho_valev
