Dynamical Implications of Adjustments to Proper Time Caused by Higher Dimensions: A Note
Dynamical Implications Higher Dimensions
2010/11/16
When the proper time of general relativity is adjusted to reflect the possible existence of higher dimensions, small dynamical effects appear in spacetime of the sort usually associated with the cosmo...

The Feynman Propagator for Quantum Gravity: Spin Foams, Proper Time, Orientation, Causality and Timeless-Ordering
Quantum Gravity Spin Foams Proper Time Orientation Causality Timeless-Ordering

We discuss the notion of causality in Quantum Gravity in the context of sum-over-histories approaches, in the absence therefore of any background time parameter. In the spin foam formulation of Quantu...
