yeah i know, the moon is getting pushed outwards, therefore needing longer for one circle arround earth which causes friction between then which makes earth spin slower

if a modern human now would go to live on a different planet they would maintain their current sleep schedule

if humans were to live on a different planet for millions of years our biology would probably set itsself to the day night cycle of that planet

altho i once heard something about humans having a 25h inner clock but dont pin me down on that
