I believe Bell's theorem specifically rules out local hidden variable theories, not all hidden variable theories.

- a1369209993 4y agoTechnically, even then it only rules out efficient local hidden variable theories. A theory where every particle carries a local hidden variable containing the entire state of the universe can (obviously?) emulate any other theory, quantum or otherwise (with a bit of finangling for things like quantum field wierdness).
- SideQuark 4y agoYes, you're correct. However, nonlocal hidden theories bring other issues that don't seem plausible. That's why the best current quantum field theories do make radiation a purely random event. None use nonlocal hidden variables.
