  Because of the non-locality of quantum entanglement, realist approaches to
completing quantum mechanics have implications for our conception of space.
Quantum gravity also is expected to predict phenomena in which the locality of
classical spacetime is modified or disordered. It is then possible that the
right quantum theory of gravity will also be a completion of quantum mechanics
in which the foundational puzzles in both are addressed together. I review here
the results of a program, developed with Roberto Mangabeira Unger, Marina
Cortes and other collaborators, which aims to do just that. The results so far
include energetic causal set models, time asymmetric extensions of general
relativity and relational hidden variables theories, including real ensemble
approaches to quantum mechanics. These models share two assumptions: that
physics is relational and that time and causality are fundamental.
