WebUsing the classical vacuum solutions of Newtonian gravity that do not explicitly involve matter, dark matter, or the gravitational constant, subject to an averaging process, a form of gravity relevant to the flattening of galaxy rotation curves results. The latter resembles the solution found if the vacuum is simply assigned a gravitational field density, and a … WebConsider that gravity is a weak force, coulombs or charge strong, with distance equal: Force of gravity = mass1×mass2/d², Force of charge = …
