WebThe Newtonian theory of gravity is based on an assumed force acting between all pairs of bodies—i.e., an action at a distance. When a mass moves, the force acting on other masses had been considered to adjust instantaneously to the new location of the displaced mass. That, however, is inconsistent with special relativity, which is based on the axiom that all … WebWhen gravitational instability is present in the ocean or atmosphere, nonhydrostatic movements tend to restore stability through narrow columns of convection, rising plumes …
