Default The Fatal Achilles Heel of Einstein's Relativity

As the observer starts moving away from the light source, his motion is obviously unable to change the wavelength of the light chasing him. This statement is a truism and yet it is fatal for Einstein's relativity. The frequency measured by the observer shifts from f to f'=(1-v/c)f, where v is the speed of the moving observer relative to the source, and the speed of the light relative to the observer shifts, accordingly, from c to c'=c-v, in violation of Einstein's relativity.

Actually any correct interpretation of the Doppler effect (moving observer) is based, explicitly or implicitly, on the trivial fact that the motion of the observer is unable to change the wavelength of the incoming light. That is, any correct interpretation of the Doppler effect refutes Einstein's relativity. Here are three examples of stating the trivial fact explicitly:

http://farside.ph.utexas.edu/teachin...ml/node41.html
"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. If f is the wave frequency (in hertz) seen by the stationary observer then the wave frequency seen by the moving observer is

f' = (1 - Uo/v)f

where v is the characteristic wave speed. [...] In fact, when applied to light propagation in a vacuum, the formula is only accurate up to first-order in Uo/c and Us/c (Rindler 1997). In other words, for light propagation the previous equation reduces to

f' = [1 - U/c + 0(U^2/c^2)]f

where U is the relative radial velocity of the source with respect to the observer." [end of quotation]

http://physics.ucsd.edu/students/cou...cs2c/Waves.pdf
"Doppler effect [...] Let u be speed of source or observer [...] Doppler Shift: Moving Observer. Shift in frequency only, WAVELENGTH DOES NOT CHANGE. Speed observed = v+u [...] Observed frequency shift f'=f(1±u/v)"

http://www.einstein-online.info/spotlights/doppler
Albert Einstein Institute: "Here is an animation of the receiver moving towards the source:

http://www.einstein-online.info/imag...ler_static.gif (stationary receiver)

http://www.einstein-online.info/imag...ector_blue.gif (moving receiver)

By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, THE DISTANCES BETWEEN SUBSEQUENT PULSES ARE NOT AFFECTED, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses." [end of quotation]

Default The Fatal Achilles Heel of Einstein's Relativity

When the observer starts moving relative to the light source, the wavelength (or distance between pulses) obviously remains unchanged, and the speed of the light relative to the observer obviously changes, in violation of Einstein's relativity:

"Doppler effect - when an observer moves towards a stationary source. ...the velocity of the wave relative to the observer is faster than that when it is still."

http://www.youtube.com/watch?v=SC0Q6-xt-Xs
"Doppler effect - when an observer moves away from a stationary source. ....the velocity of the wave relative to the observer is slower than that when it is still."

It takes an idiot to believe that the motion of the observer can change the wavelength:

http://lewebpedagogique.com/physique...8doppler_p.gif

http://astro.berkeley.edu/~mwhite/da...plershift.html
Professor Martin White, UC Berkeley: "...the sound waves have a fixed wavelength (distance between two crests or two troughs) only if you're not moving relative to the source of the sound. If you are moving away from the source (or equivalently it is receding from you) then each crest will take a little longer to reach you, and so you'll perceive a longer wavelength. Similarly if you're approaching the source, then you'll be meeting each crest a little earlier, and so you'll perceive a shorter wavelength. (...) The same principle applies for light as well as for sound. In detail the amount of shift depends a little differently on the speed, since we have to do the calculation in the context of special relativity. But in general it's just the same: if you're approaching a light source you see shorter wavelengths (a blue-shift), while if you're moving away you see longer wavelengths (a red-shift)."

http://www.pitt.edu/~jdnorton/teachi...ved/index.html
John Norton: "Every sound or light wave has a particular frequency and wavelength. In sound, they determine the pitch; in light they determine the color. Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (AND CORRESPONDINGLY FOR THE WAVELENGTH - THE DISTANCE BETWEEN CRESTS - TO HAVE DECREASED)."

Tom Roberts: "Wavelength is not an intrinsic property of light, so it cannot be discussed independent of how it is measured. But it is clear that in vacuum the light ray itself is unchanged as it propagates. Differently moving observers will measure different wavelengths for a given light ray, because their MEASURING INSTRUMENTS are oriented differently in spacetime, and such a measurement inherently PROJECTS the light ray onto the measuring instrument."
