Steven: Wrong question. “nows” aren’t slices of “Block Universe” such that there could coherently be “only a single now”. Nows are mathematical relationships in configuration space, which as a large set of mathematical relationships connected by internal inferential flow couldn’t be other than how it is.
Shane: I would say that Special Relativity imposed locality and thus destroyed the Newtonian “Static Crystal Configuration Space” view of quantum mechanics and that Barbour is trying to restore it with a relational quantum mechanics.
