There are two massive objects in the space of E[sub]0a[/sub] and E[sub]0b[/sub] energy (mass); and r[sub]a[/sub] and r[sub]b[/sub] radius; at a mutual distance of l[sub]0[/sub]; that will start to move toward each other due to the effects of gravity (or toward their joint[br]barycentre).[br][br]The total gravitational potential of bodies is “shared” together so the symmetry of motion is preserved[br](the Momentum Conservation Principle), within 4D Euclidean spacetime.
