Alternate reality

Alternate Realities
Alternate Realities stem from Einstein's Theory of Relativity. In each reality, there are often the same people, places, and objects, but with notable differences.

Appearances
Within Stargate SG-1, there have been four notable different realities.


 * SG1: There But For the Grace of God
 * Daniel Jackson is transported to a different reality via what is later called the Quantum Mirror. Some of the differences that he finds there are:
 * Earth is currently under attack from the [[Goa'uld and is slowly being wiped out.
 * He is not a part of the Stargate Program, his alternate self having turned down Catherine Langford's offer to work on the Stargate.
 * Teal'c is also not a part of the Program, and has remained the First Prime of Apophis and is currently leading the assault on Earth.
 * George Hammond is not a General, but a Colonel.
 * Jack O'Neill is not a Colonel, but a General and the head of the SGC.
 * Samantha Carter has not joined the military and is a civilian working for the SGC.
 * Jack O'Neill and Samantha Carter are engaged to be married.
 * Catherine Langford is not retired, but is still working as part of the SGC.


 * SG1: Point of View
 * An alternate Samantha Carter and Charles Kawalsky come through the Quantum Mirror, fleeing Apophis's takeover of their Earth. Some of the differences in this reality were:
 * The Stargate Program is known as the SGA.
 * Charles Kawalsky is still alive and working for the SGA.
 * Samantha Carter did not join the military and works as a civilian for the SGA.
 * Daniel Jackson did not join the Stargate Program.
 * Samantha Carter and Jack O'Neill were been married for just over a year.
 * Teal'c is still the First Prime of Apophis and, apparently, is very loyal to his master.
 * The people of this reality never met the Asgard, only coming into contact with them when Dr. Carter goes through the Stargate to ask for their help in freeing Earth from Apophis.


 * SG1: 2010
 * Ten years into the future, the Goa'uld have been defeated and the Stargate Program is public. Thanks to the Aschen, Earth is safe and humans are being given an anti-aging vaccine.  But not all that glitters is gold.
 * Note: This reality was, at first, the reality SG-1 was heading for. But thanks to the SG-1 of the future, this did become an alternate reality.  Some of the differences are:
 * The Stargate Program is public.
 * The SGC is a museum.
 * Robert Kinsey is President of the United States.
 * Samantha Carter and Jack O'Neill are both retired from the U.S. Air Force.
 * Samantha Carter is married to the Ambassador to the Aschen, Joe Faxon.
 * SG-1 is dismantled, with O'Neill estranged from his former teammates due to their difference in opinion on the Aschen's intentions.


 * SG1: Moebius, Part 2
 * The Stargate was never discovered at Giza, due to it being taken away from Earth when Ra fled, thousands of years before.
 * Note: This reality was caused by SG-1's actions in the time of Ancient Egypt and their efforts to obtain a ZPM. Some of the differences are:
 * Daniel Jackson is a teacher of languages.
 * Samantha Carter is not a member of the Air Force, and holds little of the confidence she is very well-known to have.
 * Jack O'Neill is retired from the Air Force and lives on a fishing boat.
 * Teal'c is still First Prime of Apophis, but still has his many doubts as to whether or not his master is a god.
 * Charles Kawalsky is still alive, though he dies before he can escape Chulak with the rest of the team.
