"Unending" is the season finale of the tenth season and series finale of the science fiction television series Stargate SG-1, and the show's two-hundred sixteenth episode overall. Written and directed by Robert C. Cooper, the episode originally premiered in the United Kingdom on Sky One on March 13, 2007, and in the United States on June 22, 2007 on the Sci Fi Channel. The episode attracted approximately 2.2 million viewers on its American broadcast, a ratings success for the Sci Fi Channel.
The episode begins with the mass suicide of the Asgard race, who try to preserve their legacy by giving all of their accumulated knowledge and technology to the SG-1 team and the crew of the Earth ship Odyssey. When the ship is attacked by Ori warships, Lieutenant-Colonel Samantha Carter creates a time dilation field that speeds up time within the ship, and it takes fifty years until a defense against the Ori weapons can be found.
The members of SG-1 and General Hank Landry (Beau Bridges) are travelling on the Earth ship Odyssey to the Asgard home world, Orilla, when the Asgard Thor beams aboard. He reveals that after millennia of genetic manipulation, a disease has brought his race very close to extinction, and SG-1 accepts his offer to upload the sum of all Asgard's knowledge into Odyssey as a way to preserve the Asgard legacy after their mass suicide. However, Orilla and Odyssey are soon attacked by Ori warships. Orilla erupts with huge explosions, and after Odyssey escapes to the next planet with a Stargate and beams the bulk of its crew down, the Ori fire a final energy beam upon the ship. Lieutenant-Colonel Samantha Carter (Amanda Tapping) activates a localized time dilation field that makes time look frozen outside the field to give SG-1 and Landry time to find a defense.
