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. Peter: Have you by any chance read this paper by Robert Wald “The Formulation of Quantum Field Theory in Curved Spacetime.” http://arxiv.org/abs/0907.0416 ? [2][3] Quantum field theory in curved spacetime predicts that event horizons emit radiation like a black body with a finite temperature. مخزن کتاب های فیزیک، پایگاه دانلود فیزیک - Quantum Fields in Curved Space - N. Then, there is the problem of quantization. Taking this into effect, then, requires, at the very least, a massive rewriting of quantum mechanics, as it could no longer treat space and time as fixed parameters. Since the gravitational field is determined by the curvature of spacetime, that would mean on small scales, space would not be continuous and smooth, but rather would be violently curved and fluctuating up and down. Excitations of the gravitation field give rise to the notion of length, are and volume ie.. '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. The researchers applied loop quantum gravity theory to the simplest model of Pullin emphasized that they used a very simple model in this study, consisting of only highly curved spacetime without representing the actual matter found inside real black holes. For light scalar fields, perturbation theory is plagued by infrared divergences which require resummation techniques. In loop quantum gravity, the four dimensions of spacetime are composed of networks of intersecting loops — ripples of the gravitational field.
