Obviously Variable (Newtonian) Speed of Light

Doppler effect - when an observer moves toward a stationary source https://www.youtube.com/watch?v=bg7O4rtlwEE

"Now let's see what this does to the frequency of the light. We know that even without special relativity, observers moving at different velocities measure different frequencies. (This is the reason the pitch of an ambulance changes as it passes you it doesn't change if you're on the ambulance). This is called the Doppler shift, and for small relative velocity v it is easy to show that the frequency shifts from f to f(1+v/c)... There are relativistic corrections, but these are negligible here." http://galileo.phys.virginia.edu/~pf7a/modd35.pdf

The frequency shifts from f to f' = f(1+v/c) = (c+v)/d, where d is the distance between the pulses and f is the frequency measured by the stationary observer. Accordingly, the speed of the pulses as measured by the moving observer is

c'= df' = c + v

in violation of Einstein's relativity:

"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." http://physics.bu.edu/~redner/211-sp...9_doppler.html

"Vo is the velocity of an observer moving towards the source. This velocity is 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 not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time." http://a-levelphysicstutor.com/wav-doppler.php

Einsteinians clearly see that the frequency and the speed of the light pulses vary proportionally for the moving observer, but believe that only the frequency varies - the speed of the pulses gloriously remains constant. Such a behaviour was explained long time ago:

Ignatius of Loyola: "We should always be prepared so as never to err to believe that what I see as white is black, if the hierarchical Church defines it thus."
