The execution of the UD cab be shown to be emulated (in Turing sense) by the arithmetical relation (even by the degree four diophantine polynomial). This contains all dovetailing done on almost all possible mathematical structure. This answer your question,It sounds like you are agreeing with me that yes, there is no reasonthat arithmetic would generate any sort of geometric or topologicalpresentation.

"Generating geometry" is a too vague expression.

`Keep in mind that if comp is true, the idea that there is more than`

`arithmetical truth, or even more than some tiny part of it, is`

`(absolutely) undecidable. So with comp a good ontology is just the`

`natural numbers. Then the relation with geometry is twofold: the usual`

`one, already known by the Greeks and the one related to computer`

`science, and its embedding in arithmetic.`

Or are you saying that because geometry can be reduced to arithmeticthen we don't need to ask why it exists? Not sure.

`Geometry is a too large term. I would not say that geometry is reduced`

`to arithmetic without adding more precisions.`

but the real genuine answer should explain why some geometries and topologies are stastically stable, and here the reason have to rely on the way the relative numbers can see themselves, that is the arithmetical points of view. In this case it can be shown that the S4Grz1 hypostase lead to typical topologies, that the Z1* and X1* logics leads to Hilbert space/von Neuman algebra, Temperley Lieb couplings, braids and hopefully quantum computers. No need to go that far. Just keep in mind that arithmetic emulates even just the quantum wave applied to the Milky way initial conditions. And with comp, the creature in there can be shown to participate in forums and asking similar question, and they are not zombies (given comp, mainly by step 8).The question though, is why is arithmetic emulating anything tobegin with?

`Because arithmetic (the natural numbers + addition and multiplication)`

`has been shown Turing complete. It is indeed not obvious. In fact you`

`can even limit yourself to polynomial (of degree four) diophantine`

`relation. But you can use any Turing complete system in place of`

`arithmetic if you prefer.`

`I will give a proof of arithmetic Turing universality on FOAR, I will`

`put it here in cc.`
