The Multiverse is defined as the set of consistent histories described
by the Schroedinger equation. I make the identification that a quantum
state is an observer moment, and the set of consistent quantum
histories is the set of observer histories. As such all observer
moments are in the Multiverse.
But I appreciate this is not a widely held interpretation...
