Many worlds is not the issue for Hossenfelder. She is concerned about the
non-locality of conventional quantum mechanics. With Einstein, she wants to
rule out "Spooky action at a distance." Since many worlds cannot give a
local account of Bell-type correlations, either, that theory is of little
interest to Sabine: she insists on a local theory, and MWI is not local.

It seems that her strategy has been to find a flaw in Bell's proof that no
local hidden variable theory is possible. Since any theorem is only as good
as its premises, she sees a loophole in Bell's assumption of statistical
independence -- the hidden variables are required to be independent of the
remote detector settings. However, simply finding a flaw in Bell's theorem
does not prove that quantum physics is local. What is ultimately required
is a local account of the correlations that violate Bell's inequality. No
one has ever given such a local model.


nobody in their right mind would propose an idea as ridiculous as
