If the effective global curvature is Even assuming the existence of a realistic concept similar to the cosmological constant, in alternative approaches to quantum field theory [5] one can expect it to be generated only in the presence of standard matter. In field theories of this kind, particles . The prediction of their existence falls out of the Dirac Equation, but Einstein's model accounts for the negative energy states differently than modern quantum field theory does: Once Upon a Spacetime · 3:58 PM. Wald, Quantum Field Theory in Curved Spacetime and Black Hole Thermodynamics, University of Chicago Press 1994; The back reaction effect in particle creation in curved spacetime, Commun.

Relativity tells us that spacetime is curved, and that curvature causes the force of gravity. For light scalar fields, perturbation theory is plagued by infrared divergences which require resummation techniques. Einstein's proposed unified-field equations (fundamental laws of physics) were generally derived from a variational principle expressed in terms of the Riemann curvature tensor for the presumed space-time manifold. The fancy new piece of machinery (by then an old hat for string theorists and a really old hat for relativists) was the spin connection which allows us to connect the flat-space formalism for spinors to curved spaces. The question of the space curvature is a major one, but measuring it at large cosmological scales may be extremely difficult if the actual Universe is much larger than the observable one. Its also in the lecture series he gave, “Quantum FIeld Theory in Curved Spacetime and Black Hole Thermodyanmics”. A recent study of gamma-ray bursts finds that spacetime is smoother on the quantum scale than expected.

For more information about the spin connection in the language of quantum field theory, Bertlemann's “Anomalies in Quantum Field Theory” seems very comprehensive. Perhaps suggesting a less dense area in space say nearer the center of a galaxy v/s the extreme perimeter light could travel faster or slower until it comes to the field we know and love here called Constants.
