Our proposed reconciliation of general relativity and quantum field theory is based on a modification of their graphical instantiations, i.e., Regge calculus and lattice gauge theory, respectively. Accordingly, the fundamental structure is a graphical amalgam of space, time, and sources (in parlance of quantum field theory) called a \"spacetimesource element.\" These are fundamental elements of space, time, and sources, not source elements in space and time. The transition amplitude for a spacetimesource element is computed using a path integral with discrete graphical action. The action for a spacetimesource element is constructed from a difference matrix K and source vector J on the graph, as in lattice gauge theory. K is constructed from graphical field gradients so that it contains a non-trivial null space and J is then restricted to the row space of K, so that it is divergence-free and represents a conserved exchange of energy-momentum. This construct of K and J represents an adynamical global constraint between sources, the spacetime metric, and the energy-momentum content of the element, rather than a dynamical law for time-evolved entities. We use this approach via modified Regge calculus to correct proper distance in the Einstein-deSitter cosmology model yielding a fit of the Union2 Compilation supernova data that matches LambdaCDM without having to invoke accelerating expansion or dark energy. A similar modification to lattice gauge theory results in an adynamical account of quantum interference.", "revisions": [ { "version": "v12", "updated": "2014-07-26T19:52:57.000Z", "journal": null, "doi": null }, { "version": "v13", "updated": "2014-08-30T20:04:34.000Z" } ], "analyses": { "subjects": [ "03.65.Ud", "03.65.Ta", "03.65.Ca" ], "keywords": [ "quantum gravity", "graphical approach", "spacetimesource element", "quantum field theory", "adynamical" ], "note": { "typesetting": "TeX", "pages": 47, "language": "en", "license": "arXiv", "status": "editable", "inspire": 829943, "adsabs": "2009arXiv0908.4348S" } } }
