The Terminator follows Kyle Reese, a soldier from a post-apocalyptic future where machines rule, who is sent back to 1984 to protect Sarah Connor, the future mother of John Connor, the leader of the human resistance. A Terminator, an advanced killing machine, is also sent back to kill Sarah before John is born. The film explores paradoxes, causality loops, and the idea of a fixed versus changeable timeline, as Reese’s actions shape the very future he was sent to protect.

Time Travel Concepts
Kyle Reese is sent back in time by John Connor, only to become John’s father in the past, creating a closed loop where John’s existence depends on events that were already set in motion by his future self.
Skynet is built using technology from the Terminator that was sent back in time, meaning the AI’s creation has no clear point of origin—it exists because of itself.
Despite efforts to change events, everything unfolds exactly as history recorded it: John Connor is born, and Skynet is developed, suggesting the future is inevitable.
Sarah Connor’s survival and knowledge of the future suggest that she could alter history, even though events in the first film appear to follow a deterministic path.
Kyle Reese’s journey and John Connor’s birth reinforce the idea that history cannot be changed because Kyle was always meant to be John’s father.
John Connor exists in the future because of events that happen in the past, but those events only happen because of John’s actions in the future, creating a sequence where cause and effect are inverted.
