Default DOPPLER REFUTES EINSTEIN, CONFIRMS NEWTON

A light source emits a series of pulses the distance between which is L (e.g. L=300000 km). A stationary observer measures the frequency of the pulses to be f, their speed to be c and the distance between them to be L:

f = c/L

Let the observer start moving with speed v relative to the source (v is small so that the relativistic corrections can be ignored). The moving observer measures the frequency of the pulses to be f'=f(1±v/c)=(c±v)/L, their speed to be c' and the distance between them to be L':

f' = c'/L'

The crucial questions a

c' = ? ; L' = ?

Newton's emission theory of light gives a straightforward answer:

Newton's answer: c' = c±v ; L' = L

Einstein's special relativity says that c'=c but Einsteinians are usually silent about L'. Still f' and c' determine L' unequivocally:

Einstein's answer: c' = c ; L' = Lc/(c+v) when the observer moves towards the source ; L' = Lc/(c-v) when the observer moves away from the source.

Clearly Einstein's answer is absurd. Special relativity predicts a miraculous length contraction (which has nothing to do with the length contraction of the Lorentz transforms) when the observer starts moving towards the source and an equally miraculous length elongation when the observer starts moving away from the source.

Conclusion: The speed of light is c'=c±v, not c'=c.

f = c/L

Let the source start moving with speed v relative to the observer (v is small so that the relativistic corrections can be ignored). The moving source measures the frequency of the pulses to be f1=f, their speed to be c1 and the distance between them to be L1:

f1 = c1/L1

The crucial questions a

c1 = ? ; L1 = ?

The observer measures the frequency of the pulses coming from the moving source to be f2=f(1±v/c)=(c±v)/L, their speed to be c2 and the distance between them to be L2:

f2 = c2/L2

The crucial questions a

c2 = ? ; L2 = ?

Newton's emission theory of light gives a straightforward answer:

Newton's answer: c1 = c ; L1 = L ; c2 = c±v ; L2 = L

Einstein's special relativity says that c1=c and c2=c but Einsteinians are usually silent about L1 and L2. Still f1, c1, f2 and c2 determine L1 and L2 unequivocally:

Einstein's answer: c1 = c ; L1 = L ; c2 = c ; L2 = Lc/(c+v) when the source moves towards the observer ; L2 = Lc/(c-v) when the source moves away from the observer.

The difference between L1 and L2 in Einstein's answer makes this answer absurd. Special relativity predicts a miraculous length contraction (seen in the frame of the observer but not in the frame of the moving source) when the source starts moving towards the observer, and an equally miraculous length elongation (again seen in the frame of the observer but not in the frame of the moving source) when the source starts moving away from the observer.

That the motion of the observer cannot change observed lengths is so obvious that only a highly deranged mind would claim the opposite (the Albert Einstein Institute, by asserting that "THE DISTANCES BETWEEN SUBSEQUENT PULSES ARE NOT AFFECTED", prove that they are not so deranged):

http://faculty.washington.edu/wilkes...erference..pdf
"Sound waves have speed c, and f and L are related by c=Lf. For an observer moving relative to medium with speed u, apparent propagation speed c' will be different: c'=c±u. Wavelength cannot change - it's a constant length in the medium, and same length in moving coordinate system (motion does not change lengths). Observed frequency has to change, to match apparent speed and fixed wavelength: f'=c'/L."

http://www.einstein-online.info/spotlights/doppler
Albert Einstein Institute: "The frequency of a wave-like signal - such as sound or light - depends on the movement of the sender and of the receiver. This is known as the Doppler effect. (...) In the above paragraphs, we have only considered moving sources. In fact, a closer look at cases where it is the receiver that is in motion will show that this kind of motion leads to a very similar kind of Doppler effect. Here is an animation of the receiver moving towards the source: (...) 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."

Accordingly, for all waves (light waves included), when the observer starts moving with speed v relative to the source (v is small so that the relativistic corrections can be ignored), the speed of the waves relative to the observer shifts from c to c'=c±v, in accordance with Newton's emission theory of light and in violation of Einstein's special relativity.
