So, does this mean that observation, at a minimum, involves some
connection, or as you say "a merging" between the pair? I am trying to
think of a situation were we have a pair of observers, such as you and
I, and that each of us, when considered as an LS, is separate in one
sense and "merged" in another. More below... :-)

Yes, but this is type of situation that is modeled in Peter's papers
and "Information Flow"! If we look carefully at the chain of exchange
between the message as I composed it in my mind to the message as it
registered in your mind we do see what appears to be a series of
physical connections. This could be used as support the tentative axiom
that a unique configuration X of classical particles connects a given
pair of LSs A and B. X would define a space-time manifold, correct?
But, if we go on to ask about the possible relationships between the X
connecting A and B and Y connecting C and D, we find something strange.
There is no unique diffeomorphism that can transform X into Y and vise
versa; if there is, that would be a counterexample to your claim that
there is no parallel transport connection between the LSs fibering some
Riemannian manifold. Umm, I am not sure that of the mathematical details
of the definition of a connection. I will have to study this more

Well, considering the way that the UP is defined in LS theory, I think
that I understand your thought here. :-) Is it correct that the UP
disappears in the limit of the bound state, e.g. the LS's infinite time?

Yes, but here I am looking for the subtle differences between the
information involved in the LS's scattering state and the bound state.
In the limit defined by the bound state, the LS is strictly bisimilar to
the total universe by what I understand of the definition given below.

Yes, but like I said above, the complement of an LS when it is in a
scattering state would be different from the complement of the LS in the
bound state. The difference disappears as the exponential decay of the
scattering state evolves, correct?
The "self-dual" nature of the equivalence of any LS to its complement,
is, I believe, the key property that makes any LS strictly bisimilar to
the total universe when and only when it is in the bound state.
So, my question remains after this correction :-) : How do we quantify
the information content of an LS in a scattering state?

So, does this help us in our work? :-)

Yes, but it seems that the part of the total universe that any LS has
"access" to depends on the extent to which it is bisimilar to the total
universe. When an LS is in a scattering state, far from the equilibrium
of the bound state, would there be a variable that would quantify the
information content that is the function of this "distance" from the

Yes, but I am thinking that the "control" that the LS would have over
those "tools" that are outside would depend on its ability to encode and
manipulate the informational representations of such tools. This is part
of my thinking of how an LS is conscious of an external "world". This
relates to the notion that our minds are aware of only finite aspects of
the total universe.
What we might look at for clues as to what determines the particular
set of observables that this entails is the notion of a morphic
resonance or bisimulation between the structure of the brain and the
structure of the world that it observes. Gerald Edelman's notion of
"re-entrant maps" is of particular interest to me in this regards. See:

That makes sense to me. :-)

Yes, but this holds only in the situation of the bound state of the
total universe, does it not?
