Dagomir Kaszlikowski wrote an interesting piece published in Scientific American's online 'Guest Blog' on the topic of how macro-reality is a result of the underlying quantum mechanical, non-local reality. He relates his description to the EPA paper of Einstein and others from several decades ago. That paper has been much read in recent years in regard to its forward looking content.

One might guess that non-locality in the quantum world also means non-relativity. Space and time or space-time could perhaps be a sort of local feature of an entangled macro-quantum universe of solid states.

The quantum world seems to have non--locality in it in relation to the conventional world or universe with solid objects in it. That non-locality provides an appearance of letting particles travel faster-than light or faster than any of the macro-particles that seem to exist in the local 'reality.

Obviously one must wonder if space or time are somewhat separable features of the quantum world as it emerges into the locality of large clumps of space-time. I believe that Kaszlikowski offers a statistical entanglement and exclusion principle as a reason why non-quantum features emerge from the quantum universe. Perhaps local features are emergent characteristics something like standing temporal waves of objects in reality.

That does give one pause to wonder how the entire space-time Universe emerges from quantum non-locality letting it provide an area for objects to appear. One might think that the quantum world has everything possible within it all of the time and yet only such things that are downloaded into reality because of quantum entanglement become local reality.

Local non-quantum reality is apparently something that is just observed by intelligent beings generally as more than statistically entangling units of mass-energy. The reason for those quantum entanglements is something difficult to know. As gravity and black holes appear as space-time aspects of the macro-local reality the relation of each to quantum non-local objective clump of things-in-themselves is interesting in numerous points.

One might wonder what effect non-local quantum reality in-itself experiences in relation to local clumps of statistically entangled of apparent mass-energy? To what extent are all quantum waves unbound and non-local? Can non-locality in quantum mechanics form any meaningful structures as unbounded non-local 'objects' for-themselves?

The definition of a Universe or Metaverse isn't perhaps a referent to an infinite object, which it probably is. As human elements within that Universe or set of all sets it is challenging to be a subset that defines the infinite metaset. Well, Most everyone knows what the Universe is I would think. The physical delimitations of it change all the time as do metaphysical speculations about it.

If the Universe is a locality as a phenomenal download from an underlying pervasive non-locality the the terms referring to the material local universe are somewhat contingent and useful mostly within that locality of a Universe.

I cannot imagine how all of those quantum waves in non-locality with all possible worlldlines existing in space-timeless non-relativistic potential cohere in any meaningful sense in anything at all-even a 'Universe' of quantum non-locality.
