If a graviton existed wouldn't volume increase the effect of the gravity? For instance light we know(I think this is pretty solid) is a particle. We can see evidence of this by say a solar sail. We increase the surface area that light can hit and the energy of light hitting the sail can be used to accelerate. If gravity existed as a particle wouldn't it have more effect on stuff that has more volume? ie We know that if you drop a feather and a paper clip in a vacuum at the same time they will hit at the same time. If gravitons existed wouldn't the feather drop faster because there were more particles effecting the speed at which it would accelerate?
