Are spacetime and the gravitational quantum field (still hypothetical) separate entities? Would the gravitational field be more fundamental, one of the various entities from which spacetime as a whole is composed? Gravitons, which are believed to transmit the force of gravity, would surely be excitations of the gravitational field - however, gravity arises from the curvature of spacetime. If separate, would the curvature of spacetime simultaneously excite the gravitational field, or vice versa? Fields are defined by variables across different points in space and time, so, if the two were the same system, would the gravitational field not define itself (paradoxical)? Are there any theoretical answers to these questions; if not, would the answers be vital in unifying QFT and GR?
