...facts, but in the meantime it can be regarded as demonstrated by astronomical and physical observations, that the velocity of light does not depend on the velocity of the light-source from which it is emitted11. Thus the first way proved to be untenable, for reasons lying...

...beam sent in the direction of the Earth's motion and a beam sent at right angles to it. This shows that the velocity of light does not depend on the velocity of the apparatus used to measure it. The absence of the expected 'aether drift' was explained in 1905 by Albert...

...remained the same: no "ether wind" could be detected. The paradoxical implication of this discovery was that the velocity of light does not depend on the velocity of its source. But in that case some truly fantastic things become possible. coordinate and velocity trans-...

...associated to the ether which is by definition the medium where light propagates. Consequently, the fact that the velocity of light does not depend on the velocity of the source is a natural consequence of the existence of this medium as it is the case with sound waves....
