> Scientists often don’t talk about the first two options; this article omits them, because it’s hard to think about (and violates an assumption scientists make — that you can study bits of reality in isolation).

As far as I know, the first option (hidden variable theory) has been soundly disproven by experiment.

Not when everything is held together by a non-local glue - which I assume is what your parent comment meant with the parenthesis.

IIRC based on my reading of this a while back: the non-local glue is some sort of mega-deterministic theory where everything about the universe is encoded in some function meaning non-local stuff happens because in the end everything is in the universe.

There is some state function that takes the universe… which was my understanding of the theory and ultimately very unsatisfying.

You only need the topology to carry quantum numbers, as I understand it. Anyons are experimentally confirmed to carry non-local quantum state (ie, a single quantum value shared across the constituent electrons).

Bohm worked before recent innovations, eg,

I was thinking about Bohm's theory which is the usual example of "hidden-variables" theory. Where the (not so) "hidden" part are the actual particles and their evolution is guided by the (non-local) wave function (defined in a 3N-dimensional configuration space).

(stouset mentioned hidden variables but zmgsabst didn't - I'm not sure if that's what the latter was referring to.)
