I'm not certain I was clear in what I described as being extant. When I say
"me wearing a red sweater today" I mean "some model of the universe
identical to the one that existed yesterday with the difference that today
my sweater is red".
I'm not talking about time at all. Time is just part of the overall
structure of the multiverse. I mean, the main appeal of Everett (to me) is
that it reduces a problem which is difficult to define to a structural
description of the universe.
So you can think of one consistent object as a mathematical structure that
models our entire multiverse with all of its possibilities, from the start
of the Big Bang according to the physical laws that govern it.
For an example of an inconsistent structure I'd have to bust out some set
theory, but there are plenty of "ideas" for things which sound nice but end
up being mathematically inconsistent. Being mathematically inconsistent
takes the cow example I used earlier from the "almost none" realm to the
"none" realm. We don't have access to enough information to know with
certainty that certain states are possible, though from the psychological
perspective, any set of events could be experienced, yes.
Maybe I should reformulate what I'm saying because I think I'm being
misunderstood.
