BRIAN GREENE INADVERTENTLY DISPROVES EINSTEIN'S RELATIVITY

In explaining the relativistic Doppler effect for light (moving observer), Brian Greene derives the formula

Fobs = γ(c-v)/λ

where Fobs is the frequency measured by the moving observer, γ is the Lorentz factor, c is the speed of the light relative to the stationary source, v is the speed at which the observer moves away from the source, λ is the wavelength:

It is easy to see that the speed of the light waves relative to the moving observer is

c' = λ(Fobs) = γ(c-v),

in violation of Einstein's relativity.

Roger Barlow, Professor of Particle Physics: "The Doppler effect - changes in frequencies when sources or observers are in motion - is familiar to anyone who has stood at the roadside and watched (and listened) to the cars go by. It applies to all types of wave, not just sound. (...) 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. (...) Relativistic Doppler Effect: These results depend on the absolute velocities of the source and observer, not just on the relative velocity of the two. That seems odd, but is allowable as sound waves are waves in a medium, and motion relative to the medium may legitimately matter. But for light (or EM radiation in general) there is no medium, and this must be wrong. This needs relativity. (...) If the source is regarded as fixed and the observer is moving, then the observer's clock runs slow. They will measure time intervals as being shorter than they are in the rest frame of the source, and so they will measure frequencies as being higher, again by a gamma factor: f'=γ(1+v/c)f..."

Here the observer moves TOWARDS the light source but the rest is as in Brian Greene's analysis. The frequency measured by the moving observer is

f' = γ(c+v)/λ

and the speed of the light waves relative to the moving observer is

c' = λf' = γ(c+v),

in violation of Einstein's theory of relativity.

The argument used by Brian Greene and Roger Barlow refutes Einstein's relativity because it does not involve the insane assumption that the motion of the observer somehow changes the wavelength of the incoming waves - only this assumption can save Einstein's theory. All sane scientists know that the motion of the observer cannot change the wavelength of the incoming waves. That is, in accordance with the formula

(frequency) = (speed of the waves relative to the observer)/(wavelength)

the measured shift in frequency can only be caused by a shift in the speed of the waves relative to the observer, which is fatal for Einstein's relativity of course. Examples of sanity:

"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://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://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."

http://a-levelphysicstutor.com/wav-doppler.php
"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://physics.bu.edu/~redner/211-sp...9_doppler.html
"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."

It takes insanity to believe that the motion of the observer does change the wavelength of the incoming waves. Examples of insanity:

"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."

http://www.pitt.edu/~jdnorton/teachi...ved/index.html
"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)."

http://astro.berkeley.edu/~mwhite/da...plershift.html
"...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)."

The assumption that the motion of the light source changes the wavelength of the emitted light (or the distance between subsequent light pulses):

http://www.einstein-online.info/imag...ource_blue.gif

is false but sounds reasonable, insofar as that is the case for all other waves (other than light waves). In contrast, the assumption that the motion of the observer/receiver changes the wavelength of the incoming light (or the distance between subsequent light pulses) is idiotic so no sane scientist would advance it:

The problem is that the idiotic assumption, as I have already said in the previous posting, is the only one that can save Einstein's relativity. Many Einsteinians reject it and so inadvertently disprove Einstein's relativity:

Albert Einstein Institute: "Here is an animation of the receiver moving towards the source:

http://www.einstein-online.info/imag...ector_blue.gif

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."

We have:

(frequency) = (speed of light relative to the receiver)/(distance between subsequent pulses)

Since

(distance between subsequent pulses)

is not affected, the increase in frequency means that there is an increase in

(speed of the light relative to the receiver)

in violation of Einstein's relativity. x
