Howdy. I'm not a physics expert, but I am checking for solutions to this problem. For an individual standing on the surface of a sphere (assume a perfectly spherical earth), gravity of all atoms "pull" as per their fixed relation to that individual and their distance. While the only perceivable force is "down", there is a pull nearly sideways and and all angles downward. The question is, will this force (negated for its even-on-all-sides pull) continue at a gradient from weak to strong until it reaches its maximum gradient at straight down, or will it have "spikes" of stronger pull at definite angles downward?
