Werner Hofmann's Dream to See Einstein Wrong Fulfilled

Werner Hofmann: "My dream is to demonstrate that Einstein was wrong" 10:35: "My dream discovery is to really demonstrate that the speed of light varies with energy..." https://www.youtube.com/watch?v=Qur6CEuki00

My comment on YouTube:

That the speed of light is variable, not constant, becomes obvious as one carefully analyses the Doppler effect. When the initially stationary observer starts moving towards the light source with speed v, the frequency he measures shifts from f=c/λ to f'=(c+v)/λ. This means that either the speed of the light relative to the observer shifts from c to c'=c+v, or the motion of the observer somehow changes the wavelength of the incoming light - from λ to λ'=λc/(c+v). The latter scenario is absurd - the motion of the observer is obviously unable to change the wavelength of the incoming light. Conclusion: The speed of light is different to differently moving observers (varies with the speed of the observer), in violation of Einstein's relativity:

Quote: "Thus, the moving observer sees a wave possessing the same wavelength [...] but a different frequency [...] to that seen by the stationary observer."

Quote: "Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/λ waves pass a fixed point. A moving point adds another vt/λ. So f'=(c+v)/λ."

Quote: "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 waves you detect is higher, and is given by: f'=v'/λ=(v+vO)/λ."
