It provides an analysis of the mechanisms by which spacetime can be recovered within the framework of loop quantum gravity.
Findings
Spacetime emerges from quantum geometric structures.
Mechanisms for spacetime recovery are identified.
Insights into the classical-quantum transition in gravity.
Abstract
Spacetime as we know and love it is lost in most approaches to quantum gravity. For many of these approaches, as inchoate and incomplete as they may be, one of the main challenges is to relate what they take to be the fundamental non-spatiotemporal structure of the world back to the classical spacetime of GR. The present essay investigates how spacetime is lost and how it may be regained in one major approach to quantum gravity, loop quantum gravity.
