WebGravity does work whenever an object moves in the direction of the gravitational force. The work done by gravity depends only on the total displacement in the direction of the gravitational force. The work done by gravity corresponds to potential energy being converted into kinetic energy or vice versa. Webgravity is the attraction of anything with mass to anything else with mass. the space/time relativity theory is how gravity and time interact, which isn't necessary to 'use' gravity in the engineering/newtonian models. as for how gravity works.. their working on that, it's being studied by numerous quantum physics labs and it is in no way easy ...
