Whoa up there! At no point do I admit an absolute objective world in
this paper. If you peruse my postings on this list, you will find I
believe the opposite. I consider the Multiverse to be an objective
object, however it is not in my opinion a "world" in the usual sense
of the word.

Secondly, the collapse happens not "magically to all observers", but
rather just to that subset of observers sharing the history including
that "collapse".
