Please join the Committee on Social Theory on Tuesday, October 13th in welcoming Professor David Hunter(Interim Chair, MCLLC and Cottrill-Rolfes Chair of Catholic Studies) in a lunchtime discussion of his essay, "Sacred Space, Virginal Consecration, and Symbolic Power: A Liturgical Innovation and its Implications in Late Ancient Christianity," with Professors Leon Price and Jacqueline Couti as respondents.

In this colloquium, I would like to review a recently developed new interpretation of gravitational spacetime in terms of quantum entanglement. The AdS/CFT correspondence in string theory provides a simple holographic computation of entanglement entropy. This generalizes the well-known "Entropy=Area relation" of Bekenstein-Hawking and strongly suggests that a gravitational spacetime consists of infinitely many bits of quantum entanglement. Indeed, an explicit realization of this idea is provided by so called tensor networks, which is a geometrical way to describe a given wave function in quantum many-body systems. I would like to explain these recent developments.
