One Time, Two Times, or No Time?

From the book Einstein vs. Bergson

  • Christian Wüthrich


Contemporary research programs in fundamental physics appear to suggest that there could be two (physical) times-or none at all. This essay articulates these possibilities in the context of quantum gravity, and in particular of cosmological models developed in an approach called “Loop Quantum Gravity”, and explains how they could nevertheless underwrite our manifestly temporal world. A proper interpretation of these models requires a negotiation of an atemporal and a temporal sense of the emergence of (space)time.
