I'm having trouble grasping some of the text in my textbook. In addition to proposing that objects (and the earth) fall because they are attracted by a force, Newton apparently claimed "that there is a force of attraction between any two objects with mass." Einstein went on to suggest "that the force of attraction between two objects is due to the mass causing the space around it to curve." Well if I'm on the beach and drop a rock in the sand next to a seashell, I can see how this would work. But if the seashell is a mile down the shore and I drop the rock I don't understand how it would attract the second object towards itself or vise versa. After some distance, their forces would dissipate. Wouldn't they? Zitzewitz, Paul W., Todd George. Elliott, David G. Haase, Kathleen A. Harper, Michael R. Herzog, Jane Bray.
