Gravitons and Photon interaction

  1. Dec 16, 2008 #1
    howya - for those who hold to a theory of gravitons being the operative mechanism of gravity (as opposed to GR), i have a small question:

    since light is affected by gravity, particularly as it passes a very massive body and curves around it, and graviton theory would indicate that a near infinite number of gravitons must individually interact with each individual photon, is it true that the graviton theory posits that the path of a single photon would necessarily be a polygonal arc rather than a smooth curve?

    does this relate in some way to the idea that even a so-called smooth curve in spacetime, under GR, would also necessarily be a polygonal arc made up of planck length segments?
