Simulation and comp

Hi Bruno Marchal

Not all simulations that work in Platonia can work
down here in Contingia. For example, time in
principle can flow backward up there but it can not
flow backward down here.That's why
theories have to be tested. Simulation would
not always actually work.

This does not seem to bode well for comp.

As we are ?nside? the simulation, all attempts to measure the speed of the
simulation appear as a constant value.

Light ?xecutes? (what we call ?ovement?) at one instruction per cycle.

Any device we built to attempt to measure the speed of light is also inside the
simulation, so even though the ?utside? CPU clock could be changing speed, we
will always see it as the same constant value.

A ?ycle? is how long it takes all the information in the universe to update
itself relative to each other. That is all the speed of light really is. The
speed of information updating in the universe? (more here

I can make the leap from CPU clock frequency to the speed of light in a vacuum
if I view light as an experienced event or energy state which occurs local to
matter rather than literally traveling through space. With this view, the
correlation between distance and latency is an organizational one, governing
sequence and priority of processing rather than the presumed literal existence
of racing light bodies (photons).

This would be consistent with your model of Matrix-universe on a meta-universal
CPU in that light speed is simply the frequency at which the computer processes
raw bits. The change of light speed when propagating through matter or
gravitational fields etc wouldn? be especially consistent with this model?hy
would the ghost of a supernova slow down the cosmic computer in one area of
memory, etc?

The model that I have been developing suggests however that the CPU model would
not lead to realism or significance though, and could only generate unconscious
data manipulations. In order to have symbol grounding in genuine awareness, I
think that instead of a CPU cranking away rendering the entire cosmos over and
over as a bulwark against nothingness, I think that the cosmos must be rooted
in stasis. Silence. Solitude. This is not nothingness however, it is
everythingness. A universal inertial frame which loses nothing but rather
continuously expands within itself by taking no action at all.

The universe doesn? need to be racing to mechanically redraw the cosmos over
and over because what it has drawn already has no place to disappear to. It can
only seem to disappear through?

latency.

The universe as we know it then arises out of nested latencies. A
meta-diffraction of symmetrically juxtaposed latency-generating methodologies.
Size, scale, distance, mass, and density on the public side, richness, depth,
significance, and complexity on the private side. Through these complications,
the cosmic CPU is cast as a theoretical shadow, when the deeper reality is that
rather than zillions of cycles per second, the real mainframe is the slowest
possible computer. It can never complete even one cycle. How can it, when it
has all of these subroutines that need to complete their cycles first?
?

If the universe is a simulation (which it can't, by comp, but let us say), then
if the computer clock is changed, the internal creatures will not see any
difference. Indeed it is a way to understand that such a "time" does not need
to be actualized. Like in COMP and GR.

I'm not sure how that relates to what I was saying about the universe arising

What you are saying, like what my friend up there was saying about the CPU
clock being invisible to the Sims, I have no problem with. That's why I was
saying it's like a computer game. You can stop the game, debug the program,
start it back up where you left off, and if there was a Sim person actually
experiencing that, they would not experience any interruption. Fine.

The problem is the meanwhile you have this meta-universe which is doing the
computing, yes? What does it run on?

On the true number relations.

Indirectly on some false propositions too, as the meta-arithmetic, involving
false propositions/sentences belongs to arithmetic.

Right, so the number relations don't require any meta-computation. Why then do
their progeny require number-relations?

?

To see movies, or to chat on the net perhaps.

Your question is a bit like why do Saturn needs rings?

If it doesn't need to run on anything, then way not just have that be the
universe in the first place?

OK.

It is the arithmetical universe, or (I prefer) arithmetic truth. We cannot
really defined it.

You can call it God or Universe, but it is important to distinguish from the
physical reality, which is an internal emerging secondary structure, in the
comp setting.

I am ok with secondary structure, and I think the same thing only that it has
to be that structure is secondary to sense (the capacity to experience + the
capacity to partially experience) rather than arithmetic, because I can see why
it would serve sense to invent numbers to help keep track of things but I can't
see why keeping-track-ness would bother to create experience.

Why not? It makes sense when the keeping-track-ness is done self-referentially
by the keeper tracker, in some environment, at some level of description of
itself. The study of the brain suggests such self-represention, and computer
science can study fixed point of such self-representation, and they have, even
when super-simplified,  a rich, un-bound-able mathematical complexity.

Why are you sure they can't have experience? They might disagree with you. And
somehow, using the most classical logic of knowledge, they already disagree.
Why not listen to them?

Many people argue against comp, up to the point they believe that they don't
have to study a bit of computer science. But you would study computer science,
you might perhaps find more deep argument against comp, instead of begging the
question by confusing the person (existing somehow with comp, and rather well
described for the case of simple L?ian machine) with the crunching numbers
machine physically conceived.

You defend a reductionist conception on numbers that the existence of the
(meaning:  the person associated to such numbers know that relatively to its
most probable universal environment/computation/dream).
