Visible crew/equipment: When Scully asks Mulder, "Are you losing it?" the boom mic is at the top of the screen. (00:23:20)
Continuity mistake: When Mulder and Scully first see the artifact rubbing in Skinner's office, the rubbing is quite faint and lightly done. A couple of times during the episode, the rubbing becomes darker and heavier drawn.
Continuity mistake: At The End, when Scully is trying to wipe sand and water from the moving tide away from a section of spacecraft, she stands up and the camera pans out; she is suddenly 3 feet away from the ship and several more away from the tide line.
Factual error: This episode begins with Scully doing a voice-over about the incredible nature of our universe. The scene is very impressive visually, and would have been from the aspect of her oral presentation had it not been for a major error in the script. She says (more than once) that the universe is made up of matter and gas. This should have been "matter and energy". Gas is a form of matter.
