Even in my Metaverse String cosmology I can understand how from the beginning of the Metaverse how its machine can generate all Lobian numbers including arithmetic humans and aliens long before our universe exists and evolves conscious physical beings. What I do not understand is why those physical beings are needed.
```
```
They are not needed in the assumptions or axioms. They are "needed" because the löbian numbers cannot avoid them, and this should be understood through the whole UDA. Then the math confirms this in some way.
```

```
```
```
You say they are needed as much a a particular number is needed. But that I do not understand. Particular numbers I presume are included in all the Lobian numbers. so why are physical beings needed?
```
```
I assume the natural numbers, and elementary arithmetic. I do have the axioms:
```
0 ≠ s(x)
s(x) = s(y) -> x = y
x+0 = x
x+s(y) = s(x+y)
x*0=0
x*s(y)=(x*y)+x

```
In that theory I can prove the existence of the Löbian numbers, which basically will be the numbers coding the belief in classical logic + the axioms:
```
0 ≠ s(x)
s(x) = s(y) -> x = y
x+0 = x
x+s(y) = s(x+y)
x*0=0
x*s(y)=(x*y)+x
```
(F(0) & Ax(F(x) -> F(s(x))) -> AxF(x) for each F, arithmetical formula.
```
```
And those are the numbers that I will interview about their "persistent physical hallucinations".
```
```
I call those number Löbian because they are characterized by Löb's formula: []([]p -> p) -> []p, with "[]" denoting their arithmetical provability predicate.
```

```
```

It seems to me, especially in view of MWI,
```
```
```
Keep in mind that UDA forces us to abandon all physical assumptions, so we can't assume QM, nor time, space, energy, etc. Those are emergent pattern in the mind of the average Löbian numbers.
```

```
that the machine generates everything to begin with including the passage of time. But you seem to claim that physical beings are needed to generate all Lobian numbers.
```
```
There are no physical beings at all in the ontology (which contains only 0, s(0), ...). Physical beings are mental pattern in the mind of those numbers. It *is* a form of idealism, but it is objective idealism, as the physical reality will be a common and sharable pattern in the objective mind of all Löbian numbers.
```

```
```That I do not understand at all.
```
```
```
The TOE is elementary arithmetic (or Turing equivalent). The "observable" are recovered from sharable persistent hallucinations. It is an inside view by the machines/numbers.

They are needed like the number 1879600442671119229 is needed.

Once all löbian numbers exist, humans and aliens exists because they are Löbian numbers, among many.

In the realm of elementary arithmetic.

```
It contains infinitely many computations going through you actual states.
```
```
Apparently we share many of those computations. We have to explain why. We can succeed only in deriving the physical laws from that complex computations statistics.
```
That's the result:  a problem for the computationalist.

```
I illustrate how to solve the problem in a way which takes into account what machines (us) can really justify about us, and what is true about us, but that we cannot justify. This takes unavoidable intensional nuances which are helpful to avoid the elimination of consciousness and persons, and to provide an arithmetical interpretation of Plotinus and Plato.

We might argue that only humans can build huge telescopes and see the far away galaxies, but this would not imply that those galaxies needs humans to exist.

No, because the physical past is an indexical which eventually subsume the whole UD*, and thus some part of arithmetic.

Evolution, is, most plausibly a statistically exact account of our local history.

So far you have not dismissed my inference that comp needs humans to work.
```
```
Some alien can also bet that they have a brain, and that it is Turing emulable. In arithmetic there are infinities of numbers which, relatively to some universal number arrives at that same conclusion (and in this case we know that they are correct). Do you think we need humans for having the truth that 1+1=2? If you agree we don't, then we don't humans to have the larger set of löbian numbers and their dreams, from which physical realities emerges.
```

```
IMO if true, that in itself dismisses comp as contrary to established science.
```
```
We need humans only to explain comp to humans, but comp is basically the idea that machine/numbers can manifest consciousness in their relevant relative environment/computations.
