Does anyone else question general relativity?

    My understanding of the proof goes like this

    x -star
    | --- light ray
    | O -sun
    o -earth

    The light ray is seen to bend a tiny bit when it reaches earth.
    My question is this. If we forgot about relativity and assumed the light had a tiny but finite mass (like 10^-100 kg), wouldn't the light bend by just about the same ammount? I tried to test it but I don't know if the gravity d equation can even be approximated.

    There are other experimental tests, like the precession of the orbit of mercury which support GR.

    Doing the light deflection the Newtonian way - which is similar to your proposal - gives half the observed value.

    Do some reading in the Wiki articles.
