Classical Newtonian gravitation is considered to be an attractive force, although the mechanism by which this is manifested remains unknown. Speculation includes graviton particles, space-time warping, etc. LeSagian gravitation is considered to be a pushing force, the net result of which appears to be attractive. It coincides with, but does not necessarily depend on, various aether theories where the universe is filled with moving ‘particles’ capable of exerting forces on whatever they contact. ‘Pushing’ gravity occurs when two objects ‘shadow’ each other by blocking the flow of these particles so as to create an area where the density of the particles is less than that ‘outside’ the shadow. The higher density outside the shadow impinges on a greater surface area than the lower density within the shadow, resulting in a net pushing force which appears to be an attraction between the two bodies toward one another (gravity). This paper examines how the results for ‘pushing’ gravity between the sun and a planet compare to those for ‘pulling’ gravity, as per Newton.
