[00:00:00]There is a question. So, there is a cosmological horizon. There are different kinds of cosmological horizons.

[00:00:06]And it is a a a very good question that but people don't really even know how to phrase it.

[00:00:13]That but could it be that you can describe the whole universe in terms of a quantum theory living on a boundary of some description.

[00:00:25]And I think the guess is yes. That that the guess.

[00:00:29]But we don't even know what we mean by the boundary. Yeah. Right. It's one of the problems here. So, the the reason that Maldacena was able to show this is this works for this very specific thing called ADS space is because there's a boundary you can identify in that particular geometry.

[00:00:51]Whereas our universe is de Sitter.

[00:00:54]Right. There isn't It's not obvious what you mean by a boundary. It's not really obvious what question It You know, as you said, it's hard to find the words. It is We don't really know what question we're asking. But that rough picture that there could be a a theory of quantum theory somehow, this network of qubits that gives rise to geometry, space, time is accepted broadly. Right. So, we but when you try to get into the detail of it, it's only been fully realized for a very specific model which is kind of a toy model. It's not our universe. So, it could be that our universe does not admit that description. Could be. Could be that
