It’s all relative so how can there be?
Up is relatively based upon your point of view. If you were to be looking forward then up would be above your view. Or, if you were to be in the South then North would be defined as up. Now, if you were to be in the North but facing towards the South then going down there would be going up because it’s going upwards from your point of view.
You’re right. There’s no real argument. Up is defined relatively based on the subject.
Yeah, your right! Tell me why thoughts like this come into my head at 3 am and freak me out lol
