Doppler effect in light (stationary emitter, moving observer):
Two obvious facts in this particular scenario:
(A) The speed and the frequency of the light pulses vary proportionally for the observer.
(B) The wavelength (distance between light pulses) remains constant.
(A) and (B), valid in ANY scenario (moving emitter, moving observer, presence or absence of gravity), will become basic principles in future, Einstein-free physics.
If the speed of light is assumed constant (Einstein's physics), the formula
(frequency) = (speed of light)/(wavelength)
has absurd corollaries, e.g. "Any frequency shift entails (is caused by) an inversely proportional wavelength shift". In contrast, the formula has revolutionary corollaries if THE WAVELENGTH OF LIGHT IS ASSUMED CONSTANT (future, Einstein-free physics):
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.
