The Earth's gravity is somewhat different to orbital motion...The mass of the Earth has warped space. A heavier mass can warp space more and have more gravity but the principle is the same. That Earthly mass is reaching into another dimension. Though we are quite happy to think we are locked within the motions of the sun the sun is locked into the motions of the Milky Way and that is travelling at the speed of the expanding universe. There are friction points within a star that touches the static dimension beneath that solar mass as its energy swirls and collides within it and everytime such a friction point is exposed an atom is born harnessing that friction point as the higgs field. You see all force is born that way and Jesus Christ, under the authority of his father, told us about it using sinful man as his model.
