It may be the case that there really is a hidden variable, but it would need to communicate it's value nonlocally, which I'd argue is stranger than the universe just being somewhat random.
- Grieverheart 13y agoBell's theorem is based on the assumption of free will, see eg http://en.wikipedia.org/wiki/Superdeterminism http://en.wikipedia.org/wiki/Superdeterminism
- dllthomas 13y agoEeeeh, not quite "free will", but "choices that are not structured relative to the thing being measured", which is a much weaker assumption (though still an assumption).
- cwzwarich 13y agoThe Copenhagen interpretation is arguably the most popular interpretation of quantum mechanics and is nonlocal.
- ngoldbaum 13y agoTrue, but there are no hidden variables in the copenhagen interpretation.
