Abstract: We study one loop quantum gravitational corrections to the long range force induced by the exchange of a massless scalar between two massive scalars. The various diagrams contributing to the flat space $S$ matrix are evaluated in a general covariant gauge, and we show that dependence on the gauge parameters cancels at a point considerably before forming the full $S$ matrix, which is unobservable in cosmology. It is possible to interpret our computation as a solution to the effective field equations---which could be done even in cosmology---but taking account of quantum gravitational corrections from the source and from the observer.
