Abstract

Important features of space and time are taken to be missing in quantum gravity, allegedly requiring an explanation of the emergence of spacetime from non-spatio-temporal theories. In this paper, we
argue that the explanatory gap between general relativity and non-spatio-temporal quantum gravity theories might significantly be reduced with two moves. First, we point out that spacetime is already
partially missing in the context of general relativity when understood
from a dynamical perspective. Second, we argue that most approaches
to quantum gravity already start with an in-built distinction between
structures to which the asymmetry between space and time can be
traced back.
