Everett's MWI is based on QM which does assume a background time and the state of the

David says it better than I could have, but just to add that when I
say "I" that is just a sort of short-hand for the 1-p perspective.
There is no separate experiencer. In UDA, it's simply the notes in a
'diary', some verifiable record of that branch of the computational
histories. There isn't really a 'jumping' of anything, there are just
these different computational branches. And in saying there's one
consciousness that experiences every possible state, that doesn't
imply experiencing them simultaneously. That theoretical objective
vantage point, seeing all histories, is the privilege of God perhaps,
or no-one. (Don't jump on me about the God bit, there's obviously no
God in an arithmetical ontology). Also, just to note that this is no
more incoherent than Everett. Many Worlds implies the same view of the
