Default VULNERABLE SPECIAL RELATIVITY

http://rockpile.phys.virginia.edu/mod04/mod34.pdf
Paul Fendley: "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) (it goes up heading toward you, down away from you). There are relativistic corrections, but these are negligible here."

That is, if the frequency measured by the stationary observer is f=c/L (L is the wavelength), the frequency measured by an observer moving towards the wave source with speed v is:

f' = f(1+v/c) = (c+v)/L = c'/L

where, for all waves other than light waves, c'=c+v has a definite physical meaning: it is the speed of the waves relative to the moving observer. In Divine Albert's world c'=c+v cannot be the speed of the light waves relative to the moving observer because Divine Albert has said that, for any observer, c'=c is true and c'=c+v false. Yet many Einsteinans suspect that, since the above equations correctly describe the behaviour of all waves (light waves included), c'=c+v may have the same physical meaning in all cases (the case of light waves included).

Default VULNERABLE SPECIAL RELATIVITY

If light is "falling in a gravitational field just like a mechanical object would", then, in gravitation-free space, the speed of light varies with the speed of the observer, in violation of special relativity. See this video:

http://www.youtube.com/watch?v=FJ2SVPahBzg
"The light is perceived to be falling in a gravitational field just like a mechanical object would. (...) The change in speed of light with change in height is dc/dh=g/c."

Integrating dc/dh=g/c gives:

c' = c(1 + gh/c^2)

Equivalently, in gravitation-free space where a rocket of length h accelerates with acceleration g, a light signal emitted by the front end will be perceived by an observer at the back end to have a speed:

c' = c(1 + gh/c^2) = c + v

where v is the speed the observer has at the moment of reception of the light relative to the emitter at the moment of emission. Clearly, the speed of light varies with both the gravitational potential and the speed of the observer, just as predicted by Newton's emission theory of light.

Default VULNERABLE SPECIAL RELATIVITY

For all waves (light waves included), the moving observer and the stationary observer see the same wavelength:

http://farside.ph.utexas.edu/teachin...ml/node41.html
University of Texas: "Thus, the moving observer sees a wave possessing the same wavelength (...) but a different frequency (...) to that seen by the stationary observer. This phenomenon is known as the Doppler effect."

This means that the speed of the light waves relative to the observer varies with the speed of the observer, in violation of special relativity.

Einsteinians hate this conclusion and claim that, for all waves, the moving observer sees a wavelength different to that seen by the stationary observer, Divine Einstein, yes we all believe in relativity, relativity, relativity:

http://www.lp2i-poitiers.fr/doc/aps/...oppleffet.html
"The observer moves closer to the source. The wave received has a shorter wavelength (higher frequency) than that emitted by the source. The observer moves away from the source. The wave received has a longer wavelength (lower frequency) than that emitted by the source."
