Um so

Uh, insofar as um quantum gravity is just one more quantum theory.

I would expect the ideas to go across to it.

I mean, again, because we don't ultimately know what that theory is, that's speculative.

Um, but certainly as

I for the fragmentary bits of quantum gravity we have so far, I don't think the ever interpretation has any particular difficulties with them.

Yeah, I mean I think

I've talked to Sean about this.

I think this is a s I I I push back against that way of putting it, although

uh the sense of which I'm similar view.

I I I I'd say I'm committed to the physical existence of

that which is described by the quantum wave function.

Um but that's not l i it's gonna be easier to illustrate that if I think of an analogy.

So think about classical mechanics, yeah.

Uh I do classical mechanics in a configuration space framework, let's say.

So I've got um, you know, a single point in the configuration space represents all the states of the particles.

Uh and I can write down dynamical equations of how that point evolves.

Um I can also put a a measure over the um ve the phase space of the classical system.
