In a Newtonian Universe where gravitational and electric forces are instantly experienced, Energy is exchanged between 2 objects acting on each other in order to affect their motion. However in a relativistic universe, these forces travel at the speed of light and so given distance d between these same 2 objects, it take d/c seconds in order for the force to be experienced. Assuming I have this correct, what happens to the energy to be transferred over this time that the force is travelling before it's actually transferred to the other object. I don't think it could continue being held by the object for this time and then instantly jumping over afterwards but I can't think of a better solution and haven't had any luck researching. Anyone know? Thanks.
