*

*> [MP] Communication at microscopic, CP_2 time level reduces to
*

*> informational time development. Selves generate no p-adic entanglement
*

*> during time evolution U lasting for infinite time (nothing to do with
*

*> psychological time). Only final state is unentangled and only p-adically.
*

*> This allows information flows between selves and formation

*

*> One can calculate information currents etc.. and assign
*

*> information gains of various types to various selves.
*

*> This is fundamental but not very practical level.
*

Could you give us an explicit calculation of an information current?

*> At the level of classical spacetime surface the communication
*

*> can be seen as a formation of geometric cognitive representations.
*

*> Cognitive spacetime sheets interact with physical ones and
*

*> their behaviour reflects the behaviour of material spacetime
*

*> sheets. Wormholes mediate classical gauge fields
*

*> between spacetime sheets.
*

I find this way of modeling the mind-body problem to be very

complicated! Penrose's one graviton hypothesis explains the same thing

in a simpler way, for example... But, you are applying p-adic TGD to

everything...

*> At the macroscopic level of selves communication can be simply

*> seen as sensory experiencing. Good working hypothesis is
*

*> that various sensory experiences are determined by location
*

*> in zero modes characterizing classical world and that
*

*> various macroscopic quantum phases quantum correlating
*

*> with qualia are determined by the location more or less
*

*> uniquely.
*

Ok...

[[MP]

*> In Hitoshi's theory it never changes. In TGD entire universe is subject
*

*> to evolution. God is not something Godgiven, it envolves more and more
*

*> Godlike.
*

So, where, ontologically, do the configuration spinors exist? Is God

"within" or "outside" the Universe?

*

*> [MP] It is so economical to speak just one quantum computation
*

*> decomposing into sub quantum computations (selves).
*

*> But you philosophical preassumption about single unchanging universe
*

*> does not allow this.
*

The single unchanging Universe allows decomposition into parts that are

not equal to each other, thus can change relative to each other. It

looks like you do not understand the basic concepts of what Hitoshi and

I am proposing. :-(

*

*> [MP] We are working with quantum computer.
*

I am thinking of a "distributes network" of many quantum computers, no

one! Each LS is a node or "terminal", the way that LS can be decomposed

makes them representable as whole networks themselves.

*> In quantum computation the entire quantum computation becomes
*

*> purely physical process, something analogous done by the reading
*

*> head of the Turing machine.
*

*> Quantum computation described by U last infinite
*

*> time: it does not make sense to speak about halting in finite
*

*> time(;-). To speak seriously, quantum computation halts by its very
*

*> nature. There is no line in program code telling when to halt. U is just
*

*> part of quantum jump which occurs including the halting.
*

Ok, I can agree with this. I just think that there is a lot of detail

that needs to be looked at!

*> My basic objection against computational
*

*> approach is that you try to apply it to basic physics.
*

*> I regard classical computation as something emerging at very
*

*> high level when selves begin to model the world and
*

*> build simulations of physics. At this level it makes sense
*

*> to speak about halting probabilities.
*

No, I am saying that "basic physics" is computation! I think that it

would help if we could focus our discussion on this question!

*

*> [MP] Fact is that GCI implies basic predictions of GRT and entire
*

*> structure of gravitational theory including even basic dynamical
*

*> principle. Without GCI one must start from scratch.
*

*> Conscious beings certainly give names to things but this is
*

*> different activity having nothing to do with Riemann geometry.
*

I do not share your pessimism! Have you ever looked at Lee Smolin's

ideas?

Ok...

*> [MP] I do not require you to agree with my view about reality!

*

I agree that this is a good thing! :-)

*> For instance, the notion of self solved not less than six
*

*

*>
*

*> a) How the notion of psychological time and its arrow emerge
*

*> from the theory: earlier approach was almost correct but
*

*> localization in zero modes and drift of cognitive spacetime
*

*> sheets were still missing from this picture.
*

*>
*

*> b) How one can understand memories about previous conscious
*

*> experience as *genuine* memories rather than only simulated
*

*> re-epxeriences.
*

*>
*

*> c) How can one understand the passive aspects of conscious experience
*

*> (sensory experience,etx..) if single quantum jump seemingly
*

*> involving selection determines the contents of conscious experience?
*

*>
*

*> d) How can one achieve objectivity of sensory expeirences, if
*

*> each quantum jump replaces universe with a new one: the progress
*

*> resulted from the observation that weaker concept of objectivity
*

*> defined as quantum statistical concept is probably enough.
*

*>
*

*> e) How can one understand binding: the earlier model
*

*> for binding was actually for sensory experience*r*s,
*

*> not experiences! Summation hypothesis for sensory experiences
*

*> leads to the hierarchy of selves.
*

*>
*

*> f) Is there any hope of understanding how universe can understand
*

*> itself and construct a theory about itself. Hierarchy of selves
*

*> and infinitely long subjective memories gives good hopes of this.
*

This is great! I just hope that you are not repeating something like

what Tipler did with "Physics of Immortality"!

Onward,

Stephen
