Thus, you don't need humans or consciousness in any form to collapse the wf. Feynman discusses this and it's quite conclusive IMO. * > > (2)If it's created by a splitting of the world, then you still have the > same questions with "splitting" in places of "collapse" except that the SE > does provide the evolution.

But if the object is macro, won't the interference terms be vanishingly small, so small that the unthinkable conclusion does not occur in the lifetime of the universe? IOW, FAPP there is no superposition and thus no enigmatic superposition.* > > Brent > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
