Let us be clear. For humans to be able to think, not only you need a
physical process, but you need a solar system, a planet, ... many
things, including much resources.
But, ...
... for the couple [thinking humans===== Earth, solar-system-physical
process-resource] you need only arithmetic.
A bit like in Everett the couple [physician's sad consciousness in
front of a collapsed wave===== a dead Schroedinger cat] you need only
the universal quantum wave.
Just that once we assume comp "enough consciously", if I can say, the
universal wave itself, if correct for observation, has to be retrieved
from a larger statistics, on all computations, going through our
local computational states.
Literally, the laws of physics are invariant from the choice of the
physical basic laws, as long as they are at least Turing universal
(synonym important for AUDA: Sigma_1 complete).
Literally: very elementary arithmetic is a good TOE:
x + 0 = x
x + s(y) = s(x + y)
x *0 = 0
x*s(y) = x*y + x
It is in *that* theory, that we have now to define the notion of
observers, believers, knowers, experiencers, experimentalists, and
formulate a part of the "measure problem". Mathematically, we can
test the first person limiting observation by the person "incarnated
by the genuine computation" in arithmetic.
Another TOE:
((K, x), y) = x
(((S, x), y), z) = ((x, z), (y, z))
It operates on the combinators, and the combinators are K or S, or (x,
y) with x and y combinators. So (K, K), (K, (K, S)), ((K, K) K), etc
are combinators.
What they do? They obeys the laws above.
Those defines Turing universal realities, and they will emulate/define
other universal realities, in the same relative proportions, which
will be the observers-universe, a coupled universal machine (it is
another way to view Löbianity (although technically it is a bit
weaker)).
Any universal machine contains in itself a sort of war between *all*
universal machines until they recognize themselves.
Obviously some universal machines get more famous than other,
apparently, like ... well arithmetic, combinators, but also, in
relation with the observable reality, quantum computers.
It makes comp testable, or at least the definition of observer,
believer, knower used in the derivation of physics, and here I provide
only the propositional physical theory (and even some choice as
different quantum logics appears in S4Grz1, Z1*, X1*, the logic of the
material hypostases, in Plotinus terms).
With comp, trying to singularize consciousness with a particular
universal machine (a physical reality), is like a move to select a
branch in a wave of realities, and can be seen as a form of cosmical
solipsism negating consciousness for vast span of arithmetical truth,
just because those realities are only indirectly accessible, by
looking below ours substitution level.
I have translated a part of the "philosophical" mind-body problem in
mathematics (and partially solve it).
I made a mistake as the mathematicians don't know about the mind body
problem, and the philosophers don't know the math (here: computer
science/mathematical logic).
The physicists, at least those who don't believe in the collapse are
closer to get the picture coherent with what can be like a physics
from the persons supported by the combinators reduction (or by the
numbers addition and multiplication), as it has to be the case if we
assume comp.
When I will have more time I will continue to explain the math needed
for this.
