Go to the end of the movie, when Zenon is trying to figure out the code to enter to stop the virus from eating away at the computers. When she enters the right one, the computers stop for a few seconds, and they show the Space Station from outside; the station stops rotating, thus the artificial gravity stops, and they should float. But in the next scene, they show everyone still standing, as if there was gravity. If the rotation that brings gravity is shut down, how can they still be standing as if there WAS gravity? Whoops!
