Live blogging: Sam Fletcher

A question from the audience: are we only asking about the connection between an “eigenstate” of a causal set and a classical spacetime.  Fletcher agrees that for present purposes, this is the question he’s interested in.  The concern is that perhaps the only workable way to approximate a spacetime is with a superposition of causal sets.  Fletcher agrees that this is an important problem but would like to focus on a more tractable one.
