Symposium: General Relativity in Its Second Century
Friday, 4 November 2016
13:30 - 15:30
Augusta F (7th Floor)
Chair: Sarita Rosenstock, UC Irvine
General relativity recently celebrated 100 years as a cornerstone of modern physics, but significant prospects for development exist: cosmological observations drive proposals for dark energy and matter, and spacetime inflation; theoretical investigations raise questions about unification with quantum mechanics, especially at spacetime singularities; and these developments keep relevant philosophical questions about physical geometry. The session investigates the most significant philosophical issues raised by these challenges: how they suggest a new understanding of geometry; underdetermination in cosmological extensions of general relativity; whether the semi-classical approach to cosmology is undermined by black hole radiation; and the 'pre-history' of the big bang in quantum gravity.
