Close... The local dynamics of GR are given by the local compositions
of LS projections into W. I am considering GR to be a model of the
"glocal" structure of extremal geodesics, but as I see it, we move from
the assumption of a single Riemannian manifold X to a supermanifold W
that has as submanifolds almost disjoint X_i. Each has a slightly
different inner product, maybe? This is an attempt to model how each
observer perceives itself to be in the center of a finite universe that
has a Robertson-Walker like metric.

Yes! The computational aspect is the way that the dynamics of the
physical (material) aspects act as the "hardware" whose tendency toward
local equilibrium generates the solution of the Lagrangian of the
"next" state, the "software" is the information content. I say
poetically: "Guided by the future, powered by the past, I become"

Yes, almost, the map to finite subset of W is a model of the "unity of
consciousness" of the LS. The quantum entanglements of the subsets
(quantum particles) of a given LS acts to unify the mapping. The
positions that are being mapped are the centers of mass of other LSs
that are being projected into W themselves. I wish I could draw a
picture of this here! The problem is that the image I have is not
reducible to 2 dimensions! :-(
The notions of positions is a relative notion in my thinking. It is
perhaps good to think of a graph were the centers-of-mass of other LSs
are the nodes and the edges are the relative overlaps in W. In this way
we define the space aspects of the observation in terms of extensions
and the time aspects in terms of durations, given the particular
internal behavior of the LS propagator.
Thus, if the LS is in a bound state, it has not time associated and all
extensions are null, e.g. LSs that are at internal equilibrium have no
space or time associated. The consequences of this when considering how
other LSs, in interaction with such, is interesting! It looks like the
situation where a worm hole, connecting separated space-time regions in
the classical GR picture, is pinched closed.

The key notion is how the "connections" are defined! LS have no a
priori connections between them, this allows connections, which define
the forces between LS, to be dependent on the local histories of the
LSs, e.g. the information content of the LS's quantum history constrains
the mapping. The fiber thus look more like a tree, N to 1 map, than a
string, 1 to 1 map.

Yes to all! :-) Also, we can reason that an empty LS maps to the whole
W, as the null or empty set. A singleton LS, e.g. an LS having a single
quantum particle maps to all singleton points of W.

Umm... I still have trouble with this wording, but I can see how you
use it, I think. I see "cognitive space-time sheets" and "material
space-time sheets" as Stone-Birkhoff duals of each other, as Pratt
defines the latter. I see the ideas implicit in the concept of a
"space-time" as applicable to both information and matter, each has
extentional and durational attributes. The identification between the
two is modeled by the "informorphism": material event A causes material
event B if and only if the information content of B implies the
information content of A, thus A -> B iff A* <= B*; "<-" is material
causation and "<=" is logical entailment or implication.
Other key differences are in the way the "physics" of the two work.
Material "bodies" are incompressible and rotatable, information "minds"
are compressible and irrotatable. Bart Kosko explains the latter
properties in his book Fuzzy Engineering...

This idea, to me, speaks to a generalization of Pratt's notions. The
transition or quantum jump from event A to event B is a process of
selecting the particular points of W that are dual to the information
content of the LS. Umm, I have been trying to work out an idea where the
points on the surface bounding an LS encode a n-ary bit of information,
but this is still very crude. I am using the ideas of Wheeler about the
information content of a Black-Hole's event horizon.

I agree with this. I believe that the notion of a homunculus existing
inside our head with a mini-humunculus inside of its head, etc. is
generated by this p-adic hierarchy of LS selves! :-)

Yes! I think of these in terms of Pratt's BODY and MIND, as defined in
ratmech.ps... An LS is a CHU space.

Umm, I am skeptical of the notion of the literal transmigration of
souls, since it assumes that the awareness of self is continuous a
priori and the idea that the self is a "rigid object" that "move in
space-time". This contradicts the basic notion of quantum jumps. I am
claiming that the notion of rigid bodies is at best an illusion!
The unity of "flow of consciousness" is given by the unitary evolution
of entanglements of the material particles that make up a mortal body.
When a body dies, the entanglements decohere and so does the unity of
consciousness that is associated. This idea looks very bleak, I know!
But I found another mechanism that models most paranormal phenomena as
well as the notion of transmigration. We need to consider that quantum
entanglements "connect" subsets of LSs that can have very different
space-times associated, thus we can are resonances in the information
content. Carl Jung's discussion of "synchronisities" is relevant!

What is "cm"? Have you read about the resonances of a fractal surface?
I have a book that discusses this. It is possible that the boundary of
an LS is a fractal in most cases! The notion of tree fibers points to

How is the metric generalize to our tree-like fibers? The "leaves" of
the tree-fibers are LSs and the truck roots into a non-zero region of W,
I think... The subtleties involved is that we can invert the picture so
that the leaves are points in W and the root is an LS... The difference
in these views is the difference between the subjective and the
objective. Umm, I am confused! :-) Maybe we say that the tree is a
fibration of LS_i x X^3_j -> W_ij ? I need to think about how to put my
picture into words better...

Umm, this seems to follow the "classical" notions. We need the
generalizations were there is not absolute space-time! The illusion of
classical emerges as a weighted averaging over many such space-times in

Yes. The dynamics involve the changes of the X^3s which I see as finite
partitions of W. The topology changes abruptly!

Yes, but I say that this occurs for each LS... The overlap of fibers in
W creates the appearance of a single space-time with a Robertson-Walker
metric, e.g. with a Hubble expansion related to the local "age" of

Could we deal with this? What if we allowed for multiple states and
think of eigenstates as not strictly orthogonal for all fibers. Remember
that the ordinary mathematics of QFT assumes binary complete knowledge
and it is obvious that such is an idealization...

I think I understand! :-)

Umm, is this saying that during the transition from classical
space-time to another, the universe is quantum mechanical? This allows
space-times with different global topologies to be connected? This
notion is very different from Hitoshi's idea, but perhaps the difference
is due to the different ways that time is treated.
I still see these as complementary! You see space-times as a priori
surfaces, subsets of the totality U that are connected by quantum jumps
"in time", Hitoshi, as I understand, sees space-times as the "clocked"
poset of observations of LS, which are a priori quantum mechanical
systems existing tenselessly as subsets of the totality U.
Thus you are proposing space-times as a priori and Hitoshi proposes
quantum local systems as a priori, this is a chicken-egg
complementarity! We need to see that this is just a matter of
