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? - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 07:01, 17 April 2025 (UTC) | 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? - [[User:Vaedez|Vaedez]] ([[User talk:Vaedez|talk]]) 07:01, 17 April 2025 (UTC) | ||

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).
