Velocity of Light
Light source (macrosource) is a set of elementary sources which have different velocities in relation to inertial frame of the macrosource. Elementary light which is emitted by an elementary source has a strictly fixed speed c in relation to that elementary source in the moment of emission. Hereby follows that the macrosource is emitting lights that have different speeds in relation to its own inertial frame. Elementary light detector can only detect the light that in relation to it has speed c. Just that kind of light is detectable in the inertial frame of the elementary detector. The constancy of speed of light is only related to the detectable light and it is exclusivly the consequence of the strict detectors selectivity. Change of relative velocity between the light source and the detector can`t effect the detectors selectivity therefore the light speed that we detect in the inertial detectors frame is always the same. But every time another light is detectable depending on that relative velocity.
