Gravity, Geometry, and Equivalence
Abstract
We show that the energymomentum fourvector of a planet, p = mu, is conserved during geodesic motion. Therefore, there is no exchange of energymomentum with the gravitational field. We discuss the meaning of a gravitational field which is free of energy, momentum, and stress.
