By dovetailing. I say "somehow", to say literally "in some fashion
those who knows what the UD is can work by themselves as exercise,
because I am lazy right now and it will make the post too much longer,
also".

Absolutely. And it does it, all by himself in the realm of numbers +
addition + multiplication.

We agree on this. See my post to Kelly. From outside, the links are
given by universal (or not) programs. From inside, it is linked to the
most probable histories + interference between the undistinguishable
one. QM without collapse confirms this, admittedly startling, view.

By accepting Church thesis, we accept Gödel's Miracle. We can define,
inside, the universal-outside. WE cannot compute the correct inside
mean, but it has to be partially computable for a physical worlds to
exists. So we can bet on reasonable approximations. The "real" comp
physics will be unusable in practice, but will explain in theory (and
thus prevent its elimination) the presence of subject.

No I really use "relation" in the usual math sense. For exemple a
binary relation on N can be seen as a subset of NXN. It is just an
association, a set of couples or triples, etc.

You are far to quick here. But there is something like that.

That is what I hope for.

The advantage of the present approach is that it presupposes only the
"yes doctor and Church thesis", all the rest emerges from, well not
OUR (the human) prejudices/dreams, but OUR (the universal machine)
prejudices/dreams.

No problem,
