|Paper - Abstract|
- Because of the non-locality of quantum entanglement, realist approaches to completing quantum mechanics1 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 theory2 of gravity will also be a completion of quantum mechanics3 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 mechanics4.
- These models share two assumptions:
- That physics is relational and
- That time and causality are fundamental.
