The only difference is that in QM the marbles don't really exist until you look at them.

Somehow they still manage to align themselves so if one person sees red the other sees blue.

Although it's even more accurate to say that if one person sees [colour] the other person sees [opposite colour].

The colours are random, but the relationship between them is fixed.

Very crudely (and rather misleadingly but never mind) this is why you can't communicate at FTL.

You need the other marble to know whether you had [colour] or [opposite colour]. And that info can't travel faster than the speed of light.

It's even more accurate to say there are no marbles anywhere - only interaction events between marble objects and people-looking-at-marble objects, and the API does not allow you to look inside either to see state.

(The state has to exist somewhere otherwise none of this would work. But Bell proves it's not inside the marbles. So it's "non-local" which is code for "we have no idea where it is".)

>we have no idea where it is.

It is probably encoded in the cosmic horizon a la Green's Theorem.

You're giving "probably" quite a workout there.

For it to be encoded at the cosmic horizon, it has to communicate with the cosmic horizon. It's hard to see it doing so, within the time frame of the experiments, without superluminal communication.

I said like greens theorem. so the boundary encodes the interior. No communication necessary.
