[about using wormholes to travel through time and space and to alter history]

[season one and two introduction]
John Crichton: My name is John Crichton, an astronaut. A radiation wave hit and I got shot through a wormhole. Now I'm lost in some distant part of the universe on a ship, a living ship, full of strange alien life forms. Help me. Listen, please. Is there anybody out there who can hear me? I'm being hunted by an insane military commander. Doing everything I can. I'm just looking for a way home.
General Ka D'Argo: I am a full-blooded Luxan, and ladies, I have so much cash in my pocket that I can assure you that the three of us will crawl out of here on our hands and knees come sunrise tomorrow morning...
General Ka D'Argo: I've been arrested for saying exactly the same thing on four different planets.
John Crichton: How do you say 'we're screwed' in your native tongue?
