Gravity, graviton and force

  1. Jun 25, 2004 #1
    Gravity is seen as an effect of spacetime curvature in GR. Why is it that QM sees gravity as a force like the other three fundamentals: Strong, weak and EM.
    If this is so, why bother envisaging on the graviton, when gravity is due to spacetime curvature and not force via virtual particles.

    Quantum physicists sincerely believe that the world is fundamantally quantum. Thus they can't accept the complicated classical physics of GR, though successful, as anything but a limiting case of some deeper quantum reality. Thus they adopt the mirror image of Einstein's belief that quantum mechanics, though successful, was incomplete and only a limiting case of some deeper classical reality. Go figure.
