What is the proposed role of a Klein bottle in explaining the matter‑antimatter asymmetry of the universe?
There is no general relativity, there is no space time, there's only the quantum threads, the embroidery, the threads out of which you embroidered this illusion of a continuous space time.
Professor Jana Levin, along with co-author Brian Green, published two papers just last month exploring what it would mean for our universe to be compactified on one of the most bizarre objects in the history of math, a Kleinbottle. This is a non-orientable surface with surprising physical properties, potentially explaining the origin of matter. Matter that composes you. Is this related to self-referentiality and unprovability? On this channel, I, Kirk Jimungle, interview researchers regarding their theories of reality with rigor and technical depth. Most approaches to CP violation, the matter over antimatter asymmetry, that is, the reason we exist rather than annihilate, put in that violation by hand as attuned parameters.
Jan 11's papers. don't. The geometry of the universe breaks the symmetry. Today we discuss what Girdle has to do with the universe, black holes as elementary particles, and even ER equals EPR, piggybacking off of the previous Juan Maldissena podcast on this channel as well. The question underneath everything is what if the deepest laws of physics are not laws at all, but geometry? Professor, is the universe a girdle sentence about itself?
So uh this is something I've definitely struggled with. I think the early universe, the creation of the universe, the idea of setting initial data for the universe, all of that sounds really self-referential. It sounds like the laws of physics are trying to say something about their own genesis. And that ingredient, the self-referential ingredient, is kind of a flag. That you might be getting into Godelian territory. I've never actually formalized this intuition, though I talk about it occasionally, and occasionally I'll talk to somebody plausible who can help me struggle through it. Uh it's always good to have a collaborator. But I haven't written it down yet in some sense. I haven't written down that Godelian expression.
But it does seem to hearken back to those original ideas about there not being a theory of everything.
Ah, okay. Well I I we gotta shut this interview off right now. That's 'cause that's the channel's
name. All right. You can add a question mark. Perfect, perfect. Now let's think about this
because a girdle sentence describes its own unprovability. So it's not merely a self-referential sentence. Right. Is there something do you mean to say more like that the universe may be a self-referential sentence or is there something girdelian about it?
Yeah, I think it's both. So let's just go back to Gödel for people who haven't thought about it for a while. Um, there was famously the liar's paradox, which which certainly Gödel would have been aware of, uh, in which the liar says this is a lie. So if it's a lie, it's true. If it's true, it's a lie, and you have this paradox that exists in language. And I think metaphysicists were sort of lightly not overly concerned about this. But what What Gdel did, which was to bring this to absolutely the next level, was to mathematize the idea. So he moves from this statement is untrue or a lie. He doesn't do that. He actually formulates this this statement is unprovable. And he mathematizes that concept. He says essentially that there is a true statement about a proof belonging within uh an axiomatic system.
That cannot be proven to be true, which is of course the claim of the statement. So the statement is true, but unprovable. And that is not inherently paradoxical or inconsistent. So Gdel says, look, I'm going to preserve my faith in the consistency of this axiomatic system. But I did just show that not all true statements, even in algebra. Can be proven to be true. And that's fantastic. Now, if you look back at the time when he was doing this and the great mathematician Hilbert had made a call to all mathematicians, not to prove all infinite true statements, which is impossible, but to at least render the fairly obvious assumption that all
