Main Question or Discussion Point
I've been reading about stellar aberration and was particularly drawn to the experiment where two telescopes are tracking a star but one is filled with water to slow the speed of light down. The results of the experiment show both telescopes to be tilted to exactly the same angle which contradicts logic. This is explained somewhat in wiki as a byproduct of length contraction. I don't understand how length contraction can fix this. Can someone help out? Thanks.
