lmao

godspeed

this is surreal

you have a universe that is infinite from "inside", but "from the outside", there's an outer boundary.

and you say

specifying the state of the universe on the boundary of a manifold is sufficient to completely specify the state inside

this would be similar to me viewing a Mandelbrot set and being able to tell its infinitely deep?

I feel I don't have enough background information to understand this article.

...space-time in the interior of the [anti-de Sitter] universe is a projection that emerges from entangled quantum particles living on its outer boundary

A projection? How would this differ if the quantum particles on the outside were not entangled?

holographic “emergence” of space-time works like a quantum error-correcting code.

holographic in what way? and how is this similar to error correcting code?

quantum error correction explains how space-time achieves its “intrinsic robustness,”

what is an example of this robustness in space-time?

...error-correcting codes can recover the information from slightly more than half of your physical qubits, even if the rest are corrupted. This fact that hinted quantum error correction might be related to the way anti-de Sitter space-time arises from quantum entanglement.

how does the effectiveness of error correcting codes, being able to recover information despite 50% corruption, explain space-time?

if anyone could point me in the right direction, I'd really appreciate it. I find this interesting and important but am not smart enough to comprehend it.
