Zoe (the emitter) travels towards Jasper (the receiver) and measures the speed of light to be c:

Let us imagine that, by using the same device, Zoe measures the wavelength of the light. Does the wavelength vary with Zoe's speed, or is it invariable? If Zoe were emitting sound waves, she would find that the wavelength does vary with her speed. Then how about the wavelength of light?

Physics wrongly teaches that the wavelength of light, just like the wavelength of sound, VARIES with the speed of the emitter:

Stephen Hawking, "A Brief History of Time", Chapter 3: "Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary." http://www.fisica.net/relatividade/s...ry_of_time.pdf

This variation of the wavelength of light contradicts the principle of relativity. If the wavelength varied, by measuring it, Zoe would know how fast she is moving, without any reference to outside objects. The wavelength of light is INVARIABLE.

Since the wavelength does not vary with Zoe's speed, Jasper measures the speed of light to be c'=c+v, not c:

Conclusion: The speed of light is VARIABLE; the wavelength of light is INVARIABLE.

The last statement, by replacing Einstein's 1905 false constant-speed-of-light axiom, will one day become the fundamental axiom of physics. Five important conclusions validly deducible from the axiom "The wavelength of light is invariable":

Premise 1: The wavelength of light is invariable.

Premise 2: The formula (frequency) = (speed of light)/(wavelength) is correct.

Conclusion 1: Any frequency shift entails (is caused by) a speed-of-light shift.

Conclusion 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.

Conclusion 3: Spacetime is an absurdity. Gravitational waves (ripples in spacetime) don't exist - LIGO conspirators fake them.

Conclusion 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 nonsense.

Conclusion 5: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is STATIC, not expanding.
