This has to do with the concept of neighborhood of a point, that

Hausdorfness property. Your "almost-disjointness" is "pictorially" the

same as my notion! The problem I have is with the idea that "spaces"

exist a priori to observation. We do not have a good concept of a

statistical operator for space and time! Schommers offers such! But I

have a problem with some interpretation notions he uses...

I think of a space-time as a construct, as a subjective perception. It

is no less "real" It is just not assumed to have properties independent

of the particular subjective state. Thus, if there exist an infinity of

observations, there would also co-exist an infinity of space-time

framings. This is, to me the essence of the subject-object dichotomy.

*

Ah, but it is assuming that there is a subjective independent cosmic

time! This is the problem! We can use the RW metric with the

understanding that each observer, having their own time, has its own

perseption of a Hubble expansion.

*

Yes. If the LS is in a bound state, it is a closed system in a single

state, incapable of interacting with other LSs. It's internal propagator

generates no clocking action and thus only maps to a single point of W.

In a scattering state, thus has a multiplicity of states that can map to

different points which are considered as the outsides of other LSs. So

in a sense the LS theory identifies the exteriors of LSs with points in

some type of manifold that under very general conditions models a

classical world, but this is only half of the picture! :-)

There is more involved but I need to have Hitoshi's input and he is

very busy now.

Yes, the LSs can be composed of LSs themselves. I originally asked

Hitoshi if ultra-metrics could be used to think about the hierarchical

relationships of the components of LSs... I see the tree like aspect of

the fiber as defining the ordering of the LS. The history is encoded in

the connections of the branches, in the phylogeny of the LS...

(http://phylogeny.arizona.edu/tree/home.pages/whatisphylogeny.html) This

internal structure defines, for me, the means by which the subjective

view is projected. It constitutes the subject or "self" as a whole.

Subsets of it are separate "selfs"...

Is it necessary to consider "cognitive" behaviors as space-times? The

Chu space concept seems more fundamental as it gets to the relationships

of the primitives that make up space-times themselves, e.g. the groups

that define the Lorentz and Poincare transformations can easily be

defined in Chu space terms. It is not necessary to consider the

actuality of space-times prior to the act of observation.

I think that we should seriously consider that the act of observing is

the act of generation a space-time framing, e.g. when we observe

something, we automatically are aware of such only in the context of a

given poset of extensions and durations. These "extensions" and

"durations" are Local System-specific in the sense that the LS's

propagator determines them.

I wish I has a better grasp of the mathematics that Hitoshi uses. I can

only point to his papers. I have been under a lot stress lately and am

not thinking very clearly at all. :-(

I do not think is it possible as a Local System (LS) is purely quantum

mechanical internally, all space-time associations are done "from the

outside" point of view. This makes the subject quantum mechanical and

the object classical in the context of the subject-object dichotomy of

consciousness.

This is the one aspect of your work that troubles me. :-( I do not

understand how you deal with the information content of a "cognitive

space-time sheet", I can think of such only as having the group

theoretical properties of space-time sheets, but the idea that they are

a priori objects "I can't eat." Umm, this causes an impasse between us

that I do not like at all! :-( I hope to be able to send the Schommers

paper to you soon, (my finances are very bad!) Perhaps we can just look

at his ideas and forge ahead.

We do need to be able to falsify this idea. I think that your notions

are more falsifiable than mine, this does bother me! How can I test the

notion that each observer has its own space-time and that the common

world is merely the overlap? This is my fundamental notion... I see the

"interference patterns" in the famous two-slit experiment as evidence

Umm, I think that there is much more to this! One aspect that we have

failed to discuss is the computational issue. Perhaps Karl Svozil's

paper will help: http://tph.tuwien.ac.at/~svozil/publ/maryland.ps .

I still have serious problems, I do not think I understand your concepts

of "cognitive space-time sheets". For instance, what mechanism defines

the finite time duration? LSs have a propagator that defines its clock.

I agree. That is what I meant. But, the space-time sheet is still, for

me, something that is an aspect of the framing of an observation. Umm,

are you familiar with the discussion between Newton and Leibnitz

concerning the nature of space and time? Newton considered them to be

quantities separate from the objects and did not consider any role at

all to the subjective. Leibnitz proposed that space and time to be

merely the extensional and durational relations between objects and thus

have no meaning independent of observations. I am trying to extend

Leibnitz' notion to deal with the strange world that QM shows us.

"in-itself" or is it merely a way of communicating about the world?

something that I really would like to talk about!

Ok, I can accept that. I agree, but that I have a hard time

understanding is how this "duration" is given. How is it measured? It

seems to me to be something purely subjective and this is why I would

like to explore the possibility that the subjective sense involves a

single instance given a Universe that allows for all possible such

durations.

*

The difficulty that I see in the usual discussion of "stream of

consciousness" is that a mistake is made by not realizing that the

subjective aspect can not be objectified, or as you say modeled. The

studies of how an illusion of continuity is observed in a movie is a

good indication. All we need to do is have a model that *allows* for the

possibility of an illusion of continuity as given from a subjective

point of view. The classical model of the world does *not* allow for a

subjective point of view at all!

"Self" is a subsystem separate from what? I do not think of

consciousness as an object at all; I see it as an active relation

between an LS (a poset of quantum jumps or, in Hitoshi's terms, the

propagation of a unitary operator of a discrete quantum system) and at

least one other LS. I think that the very notion of a self is impossible

if there is not distinguishability between self and not-self. I think

that it is imperative that we discard the Newtonian notions involved in

The Calculus when trying to deal with this question since they contain

implicitly the vary notions that I am questioning!

The postulation of a configuration space seems to presuppose an

ordering and a basis for observations prior to the act of the particular

observation itself. This is very similar to the Minkowskian notion that

there exists a single space-time manifold that just "exists". The

serious problem that I have with this notion is that it presupposes that

their exists a Cauchy hypersurface of positions and momenta with

definite a priori status. This is completely contradicted by the

Heisenberg's Uncertainty relation. The interpretation of this aspect of

QM is the most troublesome for physicists! What I see is that the very

notion of a configuration space has serious problems! If we are going to

insist on using them then we much at least make their status

statistical, so we talk about statistical distributions of properties

given such and such conditions. This idea seems to be the best aspect of

the Multiple World interpretation of QM.

My problem is that I see an unanswered question being swept under the

proverbial rug: What makes the world run? We can't just postulate that a

God or Singularity "started" the world! Why do we experience time in the

first place? Why has everything not already happened?

points out that GRT field equations problematic and outlines a way out.

His theory is incomplete in this sense, again as I see it. I do not

suppose that a fixed space-time is necessary for LS theory, it gives us

a way to model an alternative.

I would like to discuss the basic notion that observations are the way

that the Universe realizes the existence of consciousness and that

partial orderings of observations can, allowing for the group theoretic

properties, generate space-time framings (subjective views) that can

overlap (have configurations that are similar) such that the appearance

of a single finite universe results.

Can we put the details of p-adics aside and just talk about

space-time's ontological status? Is it necessary and sufficient to

assume that a single unique space-time exists? If so, how?
