The team decides to travel back in time to get the ZPM and leave without changing history (based on the fact that Ra and company were most likely unaware of the ZPM's purpose), but they are unable to travel back to present time so they record a video for the United States government to find. In the alternate timeline, the government find the tape and subsequently the Stargate in Antarctica and decide to establish the Stargate Program but not to restore the original timeline.
