Light moves at a constant relative to what? The point of relativity is that light has the same speed c relative to any inertial reference frame. Thus even if another inertial reference frame moves with 0.8c relative to you, a person in that reference frame will still measure light speed as c relative to his reference frame.
lets see. person a is moving away from person b at .8 speed of light, and light headed in the opposite direction is moving away from him at speed of light so the light is moving away from person a (who has not changed his speed at all) at 1.8 times the speed of light? no. its the perception that is the key. it would appear to person b that the light is moving away from him at light speed, but the light would still be moving away from person a at the same speed. he never altered his movement. light never sped up. the light is moving the same speed for both of them. just they perceive it differently.

the more man learns, the more he realises, he really does not know anything.
