  1. when we move to quantum field theory, a more advanced version of quantum mechanics that describes the electromagnetic field and other fields of nature. A field is a highly entangled system. Different parts of it are mutually correlated

    If you build two such detectors, one that accelerates and one that decelerates at the same rate, then the particles seen by one detector will be correlated with the particles seen by the other. The first detector might pick up a string of stray particles at random intervals. Minutes or years later, the second detector will pick up another string of stray particles at the same intervals—a spooky recurrence of events. “If you just look at them individually, then they’re randomly clicking, but if you get a click in one, then you know that there’s going to be a click in the other one if you look at a particular time,” Ralph said.

    At the designated future time, your descendants measure the field with the paired detector. The two outcomes, together, will reconstitute the original information. “The state is disembodied for the time between the two measurements » , but is encoded somehow in these correlations in the vacuum

    Only when these indeterminate causal relations between events are pruned away—so that nature realizes only some of the possibilities available to it—do space and time become meaningful. Quantum correlations come first, space-time later
