After our chat, Gradoe sent me an email. The first part about the blog and his privacy aren’t important, but he suggested I mention the rest, so I’ll just do a cut and paste:
‘… you probably know how this whole spacetime emergence thing has gotten under my skin. These fine AdS/CFT folks using string theory to predict that spacetime emerges from quantum entanglement arising from correspondence of conformal field theory and anti-de Sitter space from General Relativity. It’s all so obvious! Then that darned Susskind comes along and says “We don’t LIVE in anti-de Sitter space, we live in something much closer to de Sitter space.” Next thing you know he’ll be spinning off nonsense about that foamy loop quantum gravity stuff.’
‘There are three ways to settle this:
- Study advanced mathematics and theoretical physics for the next eight years, and probably still not know.
- Google it and sort through the offal that spews from the Google Sluice Gate.
- Take a poll.’
‘Covid vaccination issues have been so efficiently settled by public opinion that 3 is certainly the best approach. So why not ask your fungate readers to vote: de Sitter, or anti-de Sitter? Which space do you live in? The gut feel of your 1000’s of readers will settle it.’
Great idea, Gradoe! Folks, please vote in the comments. The comment button is at the top of the screen.
Well – the only word I understood in all of that is “sitter” and I sit a lot so I’m going to throw in my lot with Susskind and go with de sitter.
I’m with Mary…I think.
