Quantum Fields in Curved Space (Cambridge Monographs on Mathematical Physics). Gravitons are virtual excitations of the curvature of space-time, treated as a quantum mechanical field. Usually the semiclassical expansion is formulated using the background field method of quantum field theory (QFT) in Lagrangian framework [3–6]. Strings in curved background is a well-studied problem [1, 2]. An interesting approach to the black hole information paradox is contained in a recent preprint: "Black holes Conserve Information in Curved-Space Quantum Field Theory", by Christoph Adami and Greg L. ItAbstractThese notes are an expanded version of lectures given at the Croatian School on Black Holes atTrpanj, June 21-25, 2010. I can't do the math, but I suspect that gravity waves from distant events are unlikely to penetrate spacetime that is locally curved by strong gravitational fields. Outer space is teaming with fields and particles. There is an entire field of study dedicated to the development of quantum field theories in general relativistic -- including time dependent -- backgrounds, called Quantum Field Theory in Curved Spacetime. Even a “perfect” vacuum would still hold vacuum energy, the Higgs field, and spacetime curvature. Gravitation: the medium of exchange is the metric of space-time itself. [2][3] Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature.
