Stargate: Continuum (2008) Timeline Explained – Every Event in Order

Ba'al used his time machine to travel back to 1939 to prevent the Stargate program from ever being created. He murdered the crew of the Achilles, the ship transporting the Stargate to the United States, believing that eliminating the Stargate would stop SG-1 from ever forming and ultimately prevent his own defeat. The captain survived long enough to destroy a bomb Ba'al had left, which prevented the ship's complete destruction.

Foreshadowing: Earlier in the film, Ba'al claims to be a clone and warns of a hidden backup plan that could threaten SG-1's plans.

In the alternate timeline created by Ba'al's changes, Mitchell never existed because his grandfather was the captain of the Achilles. Since Ba'al's attack killed most of the crew (including the original captain in this version), Mitchell's grandfather never had children, meaning Cameron was never born. This left SG-1 without one of their core members.

In the alternate timeline where the Stargate program never existed, Samantha Carter became an astronaut and died in a space shuttle accident. Without the Stargate program to focus her career on, she pursued space exploration through conventional means, which ultimately led to her death.

Ba'al's time machine was a supercomputer connected to satellites that monitored solar flares. The machine required specific solar flare activity to create the wormhole conditions necessary for time travel. SG-1 had to wait for the correct solar flare to attempt their own time travel, and when forced to act early, they dialed to 1929 instead of their intended 1939 target.

Qetesh, who was possessing Vala Mal Doran's body, became suspicious of Ba'al's unusually lenient behavior toward Earth and his extensive knowledge of the planet. Her suspicion led her to betray and kill Ba'al, after which she attempted to seize his time machine for herself to travel to the past and change history to her advantage.

In the alternate timeline, Teal'c was captured and forced to serve Ba'al as his First Prime. This was a significant betrayal as Teal'c had previously fought against the Goa'uld. Ba'al used Teal'c as a symbol of authority and control, demonstrating his dominance over former allies.

Mitchell was the only one to survive the journey to 1929 after Carter and Daniel were killed and Teal'c sacrificed himself. Mitchell infiltrated Ba'al's ship, the Achilles, when it arrived in 1929 and killed Ba'al and his forces as they came through the Stargate. This prevented the original timeline alteration, restoring history to its original state.

Ba'al's fail-safe plan was his time travel to 1939 to prevent the Stargate program from ever existing. By changing history, he hoped to eliminate the threat posed by SG-1 and ensure his own survival. However, his plan ultimately failed when Mitchell prevented the timeline alteration.

Foreshadowing: Ba'al explicitly states he is a clone with a secret fail-safe during the opening extraction ceremony.

In the alternate timeline, Vala Mal Doran was missing, presumably having vanished like Teal'c and others when Ba'al altered history. However, Qetesh, a Goa'uld Queen, was using Vala's body as a host, making Vala essentially a prisoner within her own body until Qetesh was destroyed.

The Antarctic Stargate was an ancient gate recovered from an outpost in Antarctica that contained a Zero Point Module, a powerful energy source. It was the key to accessing the ancient weapon that had previously saved Earth. When Qetesh destroyed it, SG-1 was forced to use the Russian-held Stargate from the Achilles to pursue her.

Teal'c sacrificed himself to destroy Qetesh and her forces during the battle at the 1929 Stargate. With Sam and Daniel already killed in the firefight and Mitchell needing to proceed through the gate, Teal'c stayed behind to detonate explosives that eliminated the enemy threat, allowing Mitchell to complete the mission.

In the alternate timeline where the Stargate program never existed, Daniel Jackson remained a scholarly archaeologist still trying to convince people that the pyramids were built by aliens. Without the Stargate program to validate his theories, he remained largely dismissed and unknown.

Jack O'Neill was killed in the alternate timeline by a clone of Ba'al. When the timeline shift began causing people and objects to vanish, Ba'al's clone took the opportunity to kill O'Neill, eliminating one of SG-1's greatest adversaries against the Goa'uld.
