How emission theory was disproved by de sitter binary star experiment?

  1. Sep 15, 2011 #1
    Actually I was studying on 2nd postulate of special relativity. There I saw Ritz's emission hypotheses says for an object moving directly towards (or away from) the observer at v metres per second, this light would then be expected to still be travelling at (c + v) or (c − v) metres.

    Now lets imagine an orbiter (star) trows a photon from A, another from B, another from C and another from D. Also imagine that the velocity of the photon of A is (c + v) and of C is (c-v). If this happens we would get an weird picture of the orbiter because the the distance from the orbiter to the observer is sufficient enough then the faster photon (A) would reach to the observer faster than photon of C THOUGH PHOTON of C WAS RELEASED FIRST THEN D THEN A. (assuming the orbit is a->b->c->d->a) And this means we would often see the star at random places or at multiple position at a same time. but william de sitter didn't find any such thing...Am I right? If wrong then where I am wrong?

    You see I'm noob so a nooby friendly answer will help me more :)

    You need terrestrial experiments to address the extinction question, not astronomical ones.

    See the appropriate section in the paper referenced by the FAQ
