In WALL•E when Captain McCrea is fighting for control of the Axiom, he ends up forcing the ship to abruptly list when he's thrown off of Auto. This, of course, has the undesirable side effect of throwing everyone that was gathered on the Lido Deck out of their hoverchairs, and they all go sliding down the deck until they hit the walls of the ship.
My question is: Why are they all thrown from their hoverchairs when the ship lists?
It's not as if there's an actual up or down in space; down is a relative direction and usually happens beneath your feet.
Especially when there's use of artificial gravity. The only reason we know that the Axiom is listing at all is because we see her doing so while the camera is fixed outside; to everyone else, it should've gone unnoticed.
