Can Gravitation Have a Finite Range?
Abstract
No acceptable tensor gravitational theory with arbitrarily long but finite range exists. In linear approximation, the infiniterange limit is a scalartensor mixture implying an effective mattermatter coupling different from the strictly infiniterange prediction and contradicted by experiment. Compensation of the scalar requires the admixture of a ghost scalar coupling. In the massive version of the full Einstein theory, (a) there are necessarily six rather than the five tensor degrees of freedom, (b) the energy has no lower bound, (c) the infiniterange limit seems not to exist at all, and (d) lowestorder forces are the same as in the massive linearized theory.
