Mar 18, 1999 · Authors: J.Butterfield, C.J.Isham Download PDF Abstract: We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' quantum theory and general relativity, as a 4-dimensional manifold equipped with a. and time’: although ‘quantum’ might suggest ‘discrete’, the ‘quantum na-ture of space and time’ need not mean abandoning a manifold conception of space and time at the most fundamental level. And consequently: the clash mentioned above—between the disparate bases of the ingredient theo-ries, quantum theory and general relativity.

A method has been recently proposed for defining an arbitrary number of differential calculi over a given noncommutative associative algebra. As an example a version of quantized space–time is considered here. It is found that there is a natural differential calculus over this version of quantized space–time using which the only possible torsion-free, metric-compatible, linear connection. de Sitter space gives a local, osculating and therefore prototypical representation of a curved space–time. The de Sitter geodesics allow a description as uniform straight-line motion with respec.

The stability of a quantum superposition of two different stationary mass distributions is examined, where the perturbing effect of each distribution on the space-time structure is taken into account, in accordance with the principles of general relativity. It is argued that the definition of the time-translation operator for the superposed space-times involves an inherent ill-definedness. In [1], a new approach was suggested for finding quantum structures that might, in particular, be used in potential approaches to quantum gravity that involve non-manifold models for space and/or.

Recent developments in quantum theory have focused attention on fundamental questions, in particular on whether it might be necessary to modify quantum mechanics to reconcile quantum gravity and general relativity.

Aug 07, 1989 · The emergence of classical properties in quantum gravity can be treated analogously to the theory of Brownian motion. The local scale factor √h of a three geometry, which plays the role of an intrinsic time variable in the Wheeler-DeWitt equation corresponds to the coordinate of a Brownian particle, while the conformal part of the three geometry corresponds to the heat reservoir. 978-1-107-40458-8 - Quantum Structure of Space and Time: Proceedings of the Nuffield Workshop, Imperial College London 3 21 August 1981 Edited by M.

The motivation comes from a desire to address certain deep issues that arise when contemplating quantum theories of space and time. Our basic contention is that constructing a theory of physics is equivalent to finding a representation in a topos of a certain.
