FWIW I do suspect holography has something to do with the cosmological constant problem. I think one clue comes from an old paper by Cohen, Kaplan, Nelson (https://arxiv.org/abs/hep-th/9803132). You might find it interesting. The idea is that effective field theory put in a box breaks down when you put in enough energy to form a black hole as large as the box. Which gives a link between the box size (IR scale) and the maximum, cutoff energy (UV scale). Apply this to the size of the universe and you get a connection to the cosmological constant…

Interesting, thanks

Exactly. No need for assumptions about dynamics or locality. It really makes it very sharp.

Susskind had some ideas for the holography of FRW. Strominger is usually the one associated with dS/CFT. But this kind of research is more of the form “What would holography for dS look like if it existed?” as opposed to for AdS (and variants thereof) where we have several precise examples, where the dual field theory is known.

It has to answer why the cosmological constant is so small, and why it is stable against quantum corrections. It should be able to work everything out for de Sitter before talking about FRW. But it is difficult to connect to ideas linking entanglement in a dual field theory to cosmology, since holography is much less developed for positive cosmological constant.

I can’t be the only one who finds it taxing to read AI generated articles. It is as though the soulless nature of the text requires me to put in part of my soul to extract its meaning.

The Kochen-Specker theorem just might be even stranger…

No, the protocol needs to stand on its own merit. Bitcoin proves that you do not need to dox yourself to build the most trusted protocol in existence.

I found this essay about it superinteresting: https://disinfo.zone/loureiro_chaos.html

Why should I be more worried about algorithmic breakthroughs for quantum computers than for classical computers?
