Martin Bojowald (Penn State) Thursday, November 14, 2013 at 3:30 pm Tilley Hall Room 5 The standard model of cosmology suggests that the universe started with a phase of very high density, described by general relativity as a singularity. Quantum gravity attempts to resolve the singularity by a more fundamental, microscopic theory of space-time. If its equations always remain valid, they could tell us what happened at or even before the big...
