The formula
(frequency) = (speed of light)/(wavelength)
can be combined with two axioms:
Axiom 1: The speed of light is invariable (Einstein 1905).
Axiom 2: The wavelength of light is invariable.
Axiom 1 killed physics.
Axiom 2 will resurrect it (if it's not too late). Important corollaries:
Corollary 1: Any frequency shift 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 fakes.
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.
Corollary 5: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is not expanding.
