Whether or not quantum theory is, as Einstein claimed, incomplete, it is incompatible with local realism. Bell’s experiments have now been performed in multiple variations, and the predictions of quantum theory have been confirmed each time. We now have excellent evidence that local realism is empirically false, even if quantum theory is false or incomplete. This means that realism is false, or locality is false, or both are false. There is no happy choice here for Einstein, or for our normal intuitions.
