Leon Lederman and Dick Teresi asked, "If the universe is the answer, what is the question?"*
Non-Realists such as Anton Zeilinger imply that there are no questions at a foundational level. "Zeilinger says that some of the alternative non realist possibilities are truly weird. For example, it may make no sense to imagine what would happen if we had made a different measurement from the one we chose to make. 'We do this all the time in daily life,' says Zeilinger -- for example, imagining what would have happened if you had tried to cross the road when a truck was coming. If the world around us behaved in the same way as a quantum system, then it would be meaningless even to imagine that alternative situation, because there would be no way of defining what you mean by the road, the truck, or even you."
Zeilinger assumes -- as do all Bell's theorem adherents -- that the definition of objects precedes the measurement of correlations between objects. It should be no surprise, therefore, that the assumption of quantum entanglement generates a measurement result based merely on the definition of itself. The proof of the theorem is a nonconstructive tautology.
What Bell loyalists neglect is that there *is* no way of objectively " ... defining what you mean by the road, the truck, or even you." And there doesn't need to be. The realism of continuous functions does not depend on discrete definitions -- in every experiment purporting to show quantum entanglement and violation of Bell/CHSH inequalities, the experimenter and the apparatus are independently defined as real and local.
In *no* physical naturally occurring continuous phenomenon is this the case. The orbital path of a planet in reverse obeys the same physical laws as in forward, so it does "make sense to imagine that alternative situation." Zeilinger tacitly assumes that an observer wandering into a quantum system has a definition of itself that affects the definition of other particles in the system -- thereby the classical observer creates the quantum reality.
Were that true, the classical and the quantum space would have a definite boundary. Exploring the boundary would require the classical observer to be a quantum object, so the act of measurement would actually change the definition of the observer. This doesn't happen, of course, so one has to assume nonlocality along with entanglement. Because nonlocality violates relativity, one has to assume linear superposition to make nonlocality work.
Things in relation, however, don't depend on entanglement, nonlocality or superposition *at any scale.* Things in relation are scale invariant and coordinate free.
It should have been the simplest thing -- and would have been, were topology as advanced in 1964 as it is today -- to understand that Bell's choice of measure space (the real line) where neighboring relations are linear, is the wrong fit for nature, whose measurement functions are demonstrably complete, continuous and nonlinear.
Joy's simply connected measurement framework fits the observation of strong quantum correlations without assuming a rigged space that applies only to quantum measurement. It's the space in which we live, the space in which we experiment, a space which we are not compelled to imagine exists only in a mystical quantum entangled world.
The question is: Can the simulation of a continuous function be a continuous function? It is, and so the universe is the answer. The metaphysical realism of what exists in relation cannot be other than manifestly local.
