I thought the speed of light was constant independent of the motions of the observer and light source. So I don't understand how the doppler (blue-red) shift can be observed on incomming or receding astronomical light sources?
Speed also varies depending on the medium it travels through, so what is meant when they say the speed of light is constant?
