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... -- *PS: A number of people ask me about the attachment to my email, which is of type "application/pgp-signature".
