How does the three-dimensionality of movement arise?
I'm starting to think that instead of an actual plane the position of atoms is determined by some equation of every single particle betwen all of every single other.
But if that's the case and humanity figures out the exact equation that handles reality that means it will be horrible for models. How would you fucking extrapolate x,y,z from that clusterfuck?

Also this make me wonder how inertial forces work at the edge of the universe, if my fears are correct it would be like sliding on an extremely slippery surface.
