F.Donoghue, 'General Relativity As An Effective Field Theory: The Leading Quantum Corrections' Phys. And what about the Unruh effect ??? That was based on semiclassical gravity approach??? Well, the issue is that professor Wisdom's 'breaststroke' is not particularly effective to overcome earth's gravity, as it relies on the local curvature of spacetime. Or indeed the Quantum Field, Higgs Field, New Luminiferous Ether, or whatever else we may end up calling it. Later Einstein postulated that the gravitational field was not a property of matter at all, but the result of space-time curving in response to matter. This curvature is very small, and its effects are hardly noticable in everyday life and over small distances. 'Sketchy', in my own sense that some approximations have to be made in the classical solutions of the field equations in the background of a curved space-time and bring these over to the context of a quantum field theory. Davies, 'Quantum Fields In Curved Space' (Cambridge Univ. [2][3] Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. Semiclassical gravity, is the same name used for "quantum field theory in curved-spacetime" ???
