According to Maxwell's theory, (1) the speed of light is independent of the speed of the emitter but (2) it does depend on the speed of the observer: ======================== The speed of light is locally measured c when propagated and transmitted, regardless of the speed of the transmitter, and the speed of light is locally measured c when the transmission is received by any receiver, regardless of the speed of the receiver. 1) What then is the position of the transmitter observed by the receiver at reception of light transmission? Whatever the position observed, a relative position observed, not an absolute position. 2) What then is the velocity of the transmitter observed by the receiver at reception of light transmission? Whatever the velocity observed, a relative velocity observed, not an absolute velocity. -------------- 3) The speed of light is c independent of the transmitter and receiver, it is precisely the same constant to both (300,000 kps to local 0), but neither of the questioned items (position, velocity), regarding observation, are independent....or absolute. Both of the questioned items (position, velocity), regarding observation, are either relative past (going away from the observer) or relative future (oncoming to the observer).
