SUMMARY:Lecture / Discussion:HET Brown Bag Seminar | Comments on the gravitational path integral approach to cosmology
DESCRIPTION:In this talk\, I will discuss various aspects of the gravitational path integral (GPI) approach to cosmology. First\, I will revisit the Hartle-Hawking no-boundary proposal taking into account the norms of states computed using the GPI\, and explain how this dramatically alters the predictions of the proposal. I will then propose an alternative prescription\, which relates cosmological initial conditions to asymptotically AdS boundary conditions. Preliminary results show this approach predicts a long inflationary period ending in a metastable de Sitter universe (modulo some technical issues I will discuss). Finally\, if time allows\, I will comment on recent results that the Hilbert space of closed universes is one-dimensional\, and discuss the role of an ingredient common to all proposed resolutions of this issue: ensemble averaging.
