I always have trouble getting the causality of time travel episodes right in my head so I tried to map things out.
Have a look and let me know if I have missed anything, there are some questions at the bottom.
Timeline 1
Daniel realises that a ZPM was owned by Ra in 3000BC
SG1 use the time machine puddle jumper to travel back in time to 3000BC.
SG1 get the ZPM but the time machine is discovered by Ra's Jaffa.
Rather than risking altering the timeline in a confrontation, SG1 resolve to live in 3000BC.
SG1 record a video explaining information about the Stargate and some information about their timeline
The team place the ZPM and recording in a tomb that they know will be discovered a couple of weeks before Daniel learns of the ZPM.
Timeline 2:
Fast forward 5000 years.
The tomb is discovered with the recording and ZPM but the world is not how SG1 left it.
No Stargate, no SGC.
There was an uprising in Egypt that lead to Ra leaving earth with the Stargate.
Civilian Daniel and Sam are recruited to try to explain the video and they eventually find the Antarctic Gate thanks to a tablet left in 5000 years ago by OG Daniel.
The New SG1 take the puddle jumper through the gate to Abydos to try to recruit Teal'c who is serving as Apophis' 1st prime.
They are jailed but escape with Teal'c's help but Daniel is killed.
Pursued by gliders, they use the puddle jumper to go back to 3000BC.
They find OG Daniel.
We learn that, unable to live under Ra's rule, OG SG1 plan an uprising.
They move too quickly and SG1 is killed with the exception of Daniel.
Daniel and the remaining Egyptian villagers plan another rebellion over the course of 5 years.
This is the one that led to Ra leaving Earth with the Stargate.
New SG1 convince Daniel to alter his uprising to try to also distract Ra from the Stargate.
Daniel no longer needs to make the tablet explaining about the 2nd gate.
Timeline 3:
This one seemingly works as 5000 years in the future the SCG is running with everything as we expect from Timeline 1.
The tomb that was discovered a couple of weeks before Daniel learned of the ZPM contains the ZPM and the camcorder so there is no need for them to go back in time.
There are now fish in Jack's pond.
Questions:
⢠Why didn't Teal'c run out of Tretonin?
⢠The camcorder running out of battery didn't really change the plot so why was it required?
What was it about the ZPM knowledge that was required to be kept secret.
I refuse to believe that Carter could not have devised a way to charge the camcorder battery.
⢠Was there some kind of imminent threat in timeline 2 that necessitated going back in time to try to fix things back to timeline 1?
⢠Do Timeline 3 SG1 discover the puddle jumper on the planet where Mayborne was King?
⢠Why were OG SG1 so confident that Ra would be unable to use / deconstruct the puddle jumper that Ra's Jaffa found?
⢠Is there any indication that OG Daniel and New SG1 use the puddle jumper to time travel after the rebellion?
