Let's think about this, the PAST is only given in terms of recordings
(information states encoded in physical events, which are in NOW). While
the PAST (events) is indeed gone, never to return, we project or infer a
FUTURE state/event from a comparison of PAST and NOW. Can we define this
"chance operator" such that we do not need to consider a single operator
for *all* observers, but one that is indentifiable with each observer.
The idea is that each observer was its own time, its own clocking of
the change it can observe, so the notion of NOW/PAST pairs as worlds
would identify the unique history of each observer. This is a radical
shift from thinking of observers as being embedded in a single
space-time to the notion of associating with each observer a space-time
of its own that can "overlap" with that of others.
This is different from the usual MWI, in that the worlds are not all
strictly orthogonal to each other, they can "cast shadows" on each
other! I think that there might be a correlation between the way these
"shadows" move as the angle varies and relativistic effects! I have no
idea how to phrase this mathematically! :-( BTW, that is the
dimensionality of the shadow of a 4-dimensional object?
