Warning: Speculative physics bullshit by a non-physicist
Nature just published a short commentary on a possible quantum theoretical foundation of space time. In short, it suggests that spacetime is not the reason why particles get entangled with each other (i.e. they got close enough to influence each other), but that it is the other way around: spacetime is the emergent result of the entanglement of particles. The case is not strong yet, but it would have huge implications for a grand unified theory, and possibly also for the relationship between the quantum world and computation.
