Why is the velocity of light the same irrespective of the motion of the observer that issues the light ray?

Why isn't the velocity of light given by the speed of the observer plus the speed of the light (addition of velocities)? Why does the light ray slow down and compensate or speed up and...

Question on superfluid weight : Isn't there a logical contradiction in the following statements?

A superfluid cannot be retarded by a mechanical or otherwise force, -- it is absolutely resistance-less, --this is by its very definition as a superfluid. AND A superfluid is retarded by the...

Is light a supernatural phenomenon?

How else can we explain : Imprimis : That a light ray has different lengths for different observers. (cf. B.) ii. That the length of a light ray is indeterminate? - both gigantic, and nothing,...

Is the length of a light-ray indeterminate? Is it possible that the same ray can have different lengths in a "stationary" and a "moving frame" ?

Cf. "Einstein's light-clock." https://www.youtube.com/watch?v=Mpw68rvF4pc If we transfer the argument to the Einstein- train embankment thought experiment, in which two rays are emitted...

Is it possible that two rays of light are emitted simultaneously from each end of a rod, and yet meet off-centre? at M'

The reason I'm quite sure the described curiosity exists in Nature, is the following : Imprimis: we can synchronise clocks either end of the rod. Thereafter, we can introduce a timing off-set,...

Were the "fixed Earthers" right, back in the 1300s?

William of Ockham appears to have got it right back in the twelve to thirteen hundreds (c.1287-1347) --cf. above. The proof is the "null" result of the 1887 Michelson Morley experiment, as...

Is Einstein's argument to extend the Relativity of Motion to accelerated motion (General Relativity) justified?

Einstein tries to justify (below) that an accelerated reference frame (train carriage) may be considered "at rest" but in an equiv. gravitational field. However, the frame it is moving relative to...
