oh like its solution is to stay in one hemisphere and just go in a circle following the day-night cycle i guess. but I don't see its reasoning as that rigorous that crossing must need this westward speed but probably i'm being dumb
I guess one has to check that if you are spinning around at 23.5-epsilon angle and then do the dash down the 23.5-epsilon angle in one day from the other side you cannot beat your speed of staying in one hemisphere. you could dash straight down in 12-hour timeframe and it'll need like 343 m/s or 1233 km/h which is much too high. and diagonally probably doesn't help too much? But I think it means at some tilt angle it's worth doing this? does GPT5-pro know this angle?
