You state: "One of the first assertions in his argument is that the gravitational mass of a proton is equal to zero. However, since light is bent by gravitational fields, this cannot be true. I haven't yet dug through his math but I'm betting basing an argument on false assertions leads to false revelations.:)" This is clearly wrong. What he said was that a photon at rest has zero mass. At rest, a photon has no energy, it cannot have any mass. (By special relativity E=MC^2). The reason light is bent by gravitational fields is simply because it is NOT AT REST, therefore has energy (in the form of kinetic energy) and therefore must have mass.
