  • Quotes (21)

    • Teal'c: It is powered by ionization. Jack: In the atmosphere, right. Which is caused by... yut! (holds up finger) I know this one. Magnets! Teal'c: The geomagnetic storm. Jack: Close.

    • Hammond: So the loop can be broken? Daniel: (walks over to the computer screen) Err... there's a section of text on the altar that deals specifically with the geomagnetic storms that power the device. Apparently, they recur every fifty or so years, which is why incidentally... Jack: Yes, sir! The loop can be broken!

    • Daniel: If we really have had this conversation before, then I probably pointed it out to you that there's no way I can translate this entire text in less than a day. Jack: I'm one step ahead of you... I put the whole thing on tape last time. So you don't have to start from scratch. (Jack plays the tape; nothing but static. He rams it onto the side of the table, but to no avail) Daniel: If what you say is true, then when the loop started again... your recording wouldn't have happened yet. Jack: Yeah... right. Teal'c: Did I not say your plan would be unsuccessful? Jack: Careful! Be careful!

    • Sam: I'm gonna go run a few simulations. (Sam walks away) Jack: (to himself) You run. Simulate. Let me know how it turns out. Keep me posted. Keep me apprised.

    • (after the first loop, sitting in the commissary)
      Jack: Weren't we just somewhere else?
      Daniel: Where?
      Jack: Some planet.
      Daniel: When?
      Jack: Just now.
      Daniel: No.
      Jack: Ya sure?
      Daniel: Yeah...

    Notes (8)

    • Jack O'Neill and Teal'c are shown juggling in this episode. According to several websites, Richard Dean Anderson worked as a juggler at one time.

    • Bill Nikolai (the technician O'Neill rides his bike past) also acts as Richard Dean Anderson's stunt double for the series.

    • In real life Christopher Judge plays golf and wants to join some ProAm tournaments.

    • The Fruit Loops on the spoon were actually glued there to make it look the same every day and in every shot.

    • This episode was featured in the Viewers' Favorites Stargate marathon aired by SciFi Channel during Labor Day weekend in 2005.

    Trivia (6)

    • Carter states at the end of the episode that there is no way to know how much time passed. Actually, this isn't true, they can know the time. Very few planets were in the timeloop with them. They can go anywhere they were before the day the timeloop started. If there passed more than one day, that planet wasn't in the timeloop, so the time passed regularly there, and they can calculate the real time on Earth. Even more simple to ask their own teams, who were out somewhere else during the events (and couldn't come home).

    • When Jack is trying to convince Malikai to stop the device in the final loop, reflected in the sunglasses of Jack and Sam are the stage lights used. This light is not from the sun as the direction they are facing puts the sun behind them and no other lights are seen intentionally put there.

    • Although Jack's fruit loops are glued to the spoon for the breakfast scene (as mentioned in Notes), the people walking around in the background change every time events reoccur.

    • Trivia: P4X-639 was once a colony of the Ancients. They thrived there for thousands of years until they were struck with some sort of cataclysm or disease to which end they built a time machine to avoid their destruction. Instead of sending a team of scientists to the key moment of their history, the device caused a short term continuous loop. They experienced the same day, dozens perhaps thousands of times trying to get the machine to work but in the end they gave up, shut it down and let the end come.

    • Trivia: A total of 21 different time loops are seen during the episode.

    Allusions (2)

    • Jack: D'oh Jack and Teal'c are with Hammond in his office when there is an off world activation alarm. Jack says "D'oh" as they leave the office. "D'oh" is the catchphrase of Homer Simpson, from the animated series The Simpsons. Homer usually says this when he injures himself, of after he does something stupid.

    • Jack: Why? So you can be king of Groundhog Day?
      Groundhog Day was a movie starring Bill Murray. In the movie Bill Murray's character got stuck in a time loop similar to what SG-1 was experiencing.
