No. While Wheeler has argued for MWI, his PAP is different. In
MWI there is no collapse of the wave packet, but a splitting of the
universe into branches, when observation is made. PAP is based on the
idea (of Wigner e.g.) that the wave packet collapses when information
reaches a conscious level. Thus there must be intelligent observers for
the universe to exist - i.e., consciousness enables the universe in
which it participates to exist.
> And why can God not the the conscious observer?
God can be. & because of the Incarnation, God can be not only
_conscious_ but an observer in the sense ordinarily understood in QM.
