-Every modal logician knows about necessity and possibility (for which terms/concepts 'ordinary' logic has no symbol), and speaks about possible worlds.
-But, as far as I know, nobody of them has anything written (in scientific books or journals) about the many worlds in the sense of the quantum/astrophysicists Everett Hughes or Brian de Witt, or the recent researchfindings of the multiverse.
-What could be the reason of this 'no reference'? Could this problem be based upon the distinction between the modal logical 'possibility' and the statistical 'probability' quantum and astrophysicists are using? Please your clear answer! Thanks, Marc
