Default DOPPLER DISPROVES EINSTEIN

The speed of any waves (relative to the observer) varies with the speed of the observer - a fact which is fatal for Einstein's special relativity:

http://faculty.washington.edu/wilkes...erference..pdf
R. J. Wilkes, University of Washington: "Sound waves have speed c, and f and lambda are related by c=(lambda)f. 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'/lambda."

Wilkes discusses sound waves but many scientists use EXACTLY THE SAME argument to deduce the Doppler frequency shift for light waves:

http://physics.bu.edu/~redner/211-sp...9_doppler.html
Professor Sidney Redner: "The Doppler effect is the shift in frequency of a wave that occurs when the wave source, or the detector of the wave, is moving. Applications of the Doppler effect range from medical tests using ultrasound to radar detectors and astronomy (with electromagnetic waves). (...) We will focus on sound waves in describing the Doppler effect, but it works for other waves too. (...) 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'/(lambda)=(v+vO)/(lambda)."

http://www.hep.man.ac.uk/u/roger/PHY.../lecture18.pdf
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/lambda waves pass a fixed point. A moving point adds another vt/lambda. So f'=(c+v)/lambda. (...) Relativistic Doppler Effect (...) 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'=(1+v/c)(gamma)f..."

"In time t, ct/lambda waves pass a fixed point." That is, the speed of the light waves relative to the fixed point is c.

"A moving point adds another vt/lambda." That is, in time t, (c+v)t/lambda waves pass the moving point, and the speed of the waves relative to the moving point is c'=c+v, in violation of special relativity.

If v is smaller than (1/3)c, the relativistic corrections are negligible (for v=(1/3)c gamma is 1.05) and both c'=c+v and f'=c'/lambda are virtually exact formulas no matter whether the classical or the relativistic Doppler effect is considered.
