Cosmological Inflation and the Nature of Time
D. S. Salopek
Recent advances in observational cosmology are changing the way we view the nature of time. In general relativity, the freedom in choosing a time hypersurface has hampered the impl…
The Role of Time in Physical Cosmology

The Nature of Cosmic Time
D. S. Salopek
Hamilton-Jacobi theory provides a natural starting point for a covariant description of the gravitational field. Using a spatial gradient expansion, one may solve for the phase of…
