If we are to correct the long-range action of the global inertial frame of Newtonian mechanics, shouldn't we make it the close action of the relative velocity of light?
Shinsuke Hamaji The thought experiment linked below shows that the postulates of Special Relativity cannot be maintained and the Lorentz transformation of coordinates has to be discarded:
Preprint Special Relativity thought experiment
Then the postulates of special relativity are replaced with the concept of a space rest frame.
Preprint Space Rest Frame (March 2022)
The conclusion is that distance is invariant between moving frames of reference but objects experience length contraction depending on their velocity v relative to the space rest frame K0.
Empirically the earth's gravity is working under Pressure, Temperature, and mass, not Newtonian of weight.
Example : Hot balloon air, cannot liftoff with Newtonian, but by earth's under pressure, temperature it does.
On the other hand, Speed of artificial light of electromagnetism (Flashlight ) in vacuum (depending the color) is constant, but not spectrum of sunlight that has massive of frequencies, wavelength, with visible /invisible character,
In addition, all the lights, visibility of matter is coming from sun, and this experiment wouldn't exist without natural sunlight.
