Again, not much files, but a little bit.

Um that's always gonna that's gonna give me a f a discrete, normally finite.

set of um uh of projectors.

Um and then

Um, you're not gonna have those kind of ways you're raising.

Uh I mean theoretically if you had a um

Well, I suppose either you could be looking in a spatially infinite system or you could, I don't know, start just clo clumping them smaller and smaller and smaller together.

Um whether that's actually gonna give you a decoherent branch is gonna depend on the dynamics.

You need to actually check the equations.

And

normally speaking, if you start looking at things on smaller and smaller scales, eventually you'll reach a point where quantum interference

Uh is going to become non negligible.

And then the branching language is gonna break down.

Uh as for things on a spatial infinite scale, I mean, ask your cosmology.

Uh my feeling is generally speaking

we know almost zero about real spatial infinities in physics and essentially every time we find ourselves using a spatial infinity it's a modeling idealization.

So I'm generally suspicious of spatial infinities in that sense.

And after all, the the De Sita horizon of the Oak Banding Universe is finitely far away.

Um and anything beyond that horizon is
