To me all these references to Bohmian mechanics, hidden variables and faster than light communication makes hides more than it reveals. These connections always arise because of some invariant our universe preserves, eg charge is conserved, or spin is conserved, or whatever. The universe happens to let us create particles - an electron say, from pure energy. But the conservation of charge means you can't just create an electron, there has to be a positron too otherwise charge isn't conserved. They would instantly annihilate each other if they hung around together, so in order for us to see them they must be moving away from each other (with equal but opposite momentum, because that's conserved too). Until we measure it, we don't know what the charge of either of particles is. Quantum superposition means that until we measure it, the charge of both particles is effectively in a 3rd state: unknown (as opposed to positive or negative). Putting this in terms of hidden variables, there is a variable that is in one of three states: "particle-A: Unknown charge, particle-B: Unknown charge", "A: positive, B: negative", "A: negative, B: positive". It doesn't look to me like this this variable exists everywhere. It only describes the state of these two particles which by definition occupy a tiny positions in space-time. And no it isn't unobservable either: you can observe the variable by just measuring one of the particles. It does raise all sorts of interesting questions about how the universe operates. How does it preserve these invariants across space and why are they preserved? Does this quantum superposition look anything like it's being described here? I've seen other descriptions that make it arise quite naturally from the math of 2-norm probabilities and thus not require multi-verses or some mysterious "collapse" (which look to me to be about a useful as explaining what s going on as "Bohmian mechanics"). So these hidden variables are a hand wavy way of describing how conversation laws interact QM superposition. It's not really that complex - is it? Was there any need to introduce "hidden variables" at all? It seems to me a lot of the difficulty people have in describing QM is not in QM itself, but from the knots people get themselves into in their personal struggle to understand it. They write their knots down, we gumbies read it and say "bugger me that looks hard".
