Ah so I think I sort of conflated RQM and MWI because I thought it was all about Everett’s other paper “relative state formulation of qm”.
I thought on top of an ad hoc rehabilitation of physical realism, the universal state also did something for the consistency. Something like all the density operators may be expressed as partial traces of the operator describing the their systems’ union, in order for everything to be consistent, and the ‘largest’ operator describes the state of the universe or something.
I’ll check out your sources next insomnia, thanks









I’ve been in similar situations in large or semi-large chat channels when you want to adhere to something and give the possibility to others to adhere similarly without flooding the channel with messages simply saying “me too”. So attaching an emoji reaction feels more adequate, that way anyone can just append their own and you can see groupal adhesion directly. Sometimes 💯 works, but it sometimes doesn’t.
EDIT: the more I think on it, the more an emoji saying “+1” feels like it should fill that need when 💯 doesn’t. Maybe someone should propose this to the Unicode consortium
