Talk:3077: de Sitter
the titletext still needs an explanation, but i'm not sure i get the connection to conformal field theory; i suspect it has to do with the explosive rate at which hyperolic space seems to "expand" when travelled through, as a pun on the club expanding at a similar rate? - Vaedez (talk) 07:01, 17 April 2025 (UTC) 162.158.90.137 07:21, 17 April 2025 (UTC) I think it's alluding to AdS/CFT correspondence, which I think is a string theory thing.
In hyperbolic space, parallel lines DON'T meet when extended, and in elliptic space they DO. Also, the rotation thing looks strange. In any of the basic geometries you have 360 degrees in a circle. The sum of angles in triangle will be different (smaller than 180 in hyperbolic space, larger in elliptic space). 172.68.213.151 07:58, 17 April 2025 (UTC)
- Agreed. I went and changed it. Though technically, the stuff about parallel lines is still wrong. Parallel lines don't meet by definition, and spherical geometry doesn't have them. Maybe someone can add a better explanation? DanielLC (talk) 09:19, 17 April 2025 (UTC)

Fun Fact: the german version of Anti-de Sitter space in wikipedia refers to a [Randall–Sundrum model|https://en.wikipedia.org/wiki/Randall%E2%80%93Sundrum_model]
"...less than 180° in a full rotation"
Shouldn't this be either "...less than 360° in a full rotation" (or perhaps "...the angles of a triangle add up to less than 180°").
