It's called Bell's theorem and it can even be tested at home[4]. There are no local hidden variables in quantum mechanics.[1][2][3]

- lulantivaxxers 5y agoThanks for this, hidden variable theories are very seductive but Bell's Theorem is definitive.
- naasking 5y agoIt's definitive that you have to give up locality (Bohmian mechanics), counterfactual definiteness (Copenhagen and others), or statistical independence (Superdeterminism). It's not definitive at all about local hidden variables.

- naasking 5y agoBell's theorem assumes statistical independence in its proof that local hidden variables can't reproduce QM. Superdeterminism violates statistical independence, therefore Bell's theorem does not rule out a superdeterministic local hidden variables theory, like this one: https://arxiv.org/abs/2010.01327v5 https://arxiv.org/abs/2010.01327v5
- guerrilla 5y agoOh, thank you. I've been meaning to check her blog on this.
