I just learnt how stellar abberation and the ether theory while studying Robert resnick's book. What I'm thinking is how the sky would look IF ether were to exist and be dragged along the earth as it revolved the sun. Since earth's local supply of ether is moving along with it i.e. rest w.r.t the earth shouldn't it behave like a giant layer of refractive glass over the earth? Since any light falling on it(the surface of ether layer surrounding earth) say from an angle 30° to the overhead would be propagated directly along the normal or very close to normal to maintain light's speed C wrt to earth's ether. Because if it didn't bend the light then due to earth's motion around sun (V=30 Km/s) we would see an additional speed being added ( I guess V cos 30° will be added to C and resultant will be sqrt(c²+V² cos ² 30°)) to the light ray which is would be inconsistent with the the original hypothesis itself. Is the analysis OK? Or more importantly is stellar abberation definite proof for dismissing the ether drag hypothesis? If ether drag did exist then would there be no stellar abberation?
