Davies has published over 100 research papers in the fields of black holes, cosmology, and quantum field theory in curved spacetime. 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. Einstein reportedly got the inspiration for this imaginative leap in It is now known that Newton's universal gravitation does not fully describe the effects of gravity when the gravitational field is very strong, or when objects move at very high speed in the field. Gravitation: the medium of exchange is the metric of space-time itself. Einstein later worked out how the force of gravity is not quite a force, but rather an artifact of the natural movement of objects through curved four-dimensional spacetime. 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. This is where Einstein's general theory of relativity rules. Gravitons are virtual excitations of the curvature of space-time, treated as a quantum mechanical field. Quantum Einstein Gravity (QEG) is the generic name for any quantum field theory of gravity that (regardless of its bare action) takes the spacetime metric as the dynamical field variable and whose symmetry is given by diffeomorphism invariance. This has been extended further by taking into account polynomials of the scalar curvature \(R\) (so-called \(f(R)\)-truncations) (Codello et. His monograph on Quantum Fields in Curved Space, remains a seminal text in the field of quantum gravity. Al., 2009), and the square of the Weyl curvature tensor (Benedetti et.
