There must be a “speed of gravity” based upon the speed of the impacting particles which causes the effect we see as gravity. Since there must be a “speed of gravity”, there must be a delay in its effect, caused by the distance between the body causing the effect and the body being affected. In addition, since there must be a measureable distance between a body that is the source of the effect and the body that receives the effect, there must be a limiting distance for that effect.
