"Was Einstein wrong? The idea of a variable speed of light, championed by an angry young scientist, could one day topple Einstein's theory of relativity. Einstein's famous equation E=mc^2 is the only scientific formula known to just about everyone. The "
c" here stands for the speed of light. It is one of the most fundamental of the basic constants of physics. Or is it? In recent years a few maverick scientists have claimed that the speed of light might not be constant at all. Shock, horror! Does this
mean the next Great Revolution in Science is just around the corner?" http://www.prospectmagazine.co.uk/magazine/waseinsteinwrong/
It IS around the corner. Consider Doppler effect (stationary light source, moving observer):

(frequency) = (speed of light)/(wavelength)
tolerates two axioms:
Axiom 1: The speed of light is constant.
Axiom 2: The wavelength of light is constant (for a given emitter).
Axiom 1 killed physics.
Axiom 2 will resurrect it (if it's not too late). Corollaries:
Corollary 1: Any frequency shift entails (is caused by) a proportional speed-of-light shift.
Corollary 2: If the emitter and the observer (receiver) travel towards each other with relative speed v, the speed of light as measured by the observer is c' = c+v, as per Newton's theory.
Corollary 3: Spacetime and gravitational waves (ripples in spacetime) don't exist. LIGO's "discoveries" are fake.
Corollary 4: Light falls in a gravitational field with the same acceleration as ordinary falling bodies - near Earth's surface the accelerations of falling photons is g = 9.8 m/s^2. Accordingly, there is no gravitational time dilation: Einstein's general
relativity is absurd.
Corollary 5: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is not expanding.
