In a recent archive post ([1]) Shan Gao has argued that quantum theory is incompatible with relativity. He calls this a new proof beyond Bell’s theorem, arguing elsewhere ([2]) that it closes the superdeterminism loophole in Bell’s theorem. Such strong claims must be backed up by irrefutable arguments. My aim in this post to the workshop “Beyond Bell’s theorem” is to refute Gao’s “proof” and to show how quantum theory is compatible with relativity theory and so why Gao’s “proof” does not take us beyond Bell’s theorem.
