Time travel seems to be one of those concepts that never gets old – no matter how far along we get or how much information we gather about the universe, time travel seems to remain an untouchable, mysterious theory that might just about be possible. One movie franchise that grapples with time travel is the Terminator. Directed by James Cameron, the Terminator franchise attempted to unravel the complexity of time travel, introducing us to characters like the T-800 and Sarah Connor and making us question our beliefs about science and its abilities. So, how does Terminator time travel work? Let’s get into the science behind the theory.
Quick Recap of Terminator Universe
Let’s refresh your memory if it’s been a minute since you binged all the Terminator movies. The Terminator series puts humans against Skynet’s AI machines. After the destructive Judgment Day of Skynet, John Connor takes the lead for the humans, leading a resistance. They go up against time-traveling Terminators targeting Sarah Connor, young John Connor, and Dani Ramos.
The Terminator, which debuted in 1984, was followed by Judgment Day, Rise of the Machines, Terminator Salvation, Terminator Genisys, and Dark Fate.
The series’ cast of characters include Kyle Reese, Grace, the T-800 and T-1000 Terminators, played by Arnold Schwarzenegger, Robert Patrick, and Marcus Wright, played by Sam Worthington.
How Does Terminator Time Travel Work?
One of the most significant facets of the Terminator series revolves around the concept of time travel, where both sides aim to change the past to influence the future. The key device here is the Time Displacement Equipment, or TDE. This allows characters to hop between locations. However, there’s a catch—only beings with living tissue, aka humans, can use the TDE.
The Science of Time Travel
As much as time travel intrigues you, it’s also intrigued scientists and lovers of fiction for a long time. Einstein played a pretty big role in the theory of time travel with his theory of general relativity. He suggested that time is flexible and swayed by factors including object speed and gravity.
This theory leads to time dilation, the concept that time moves differently based on the speed of said object. While this concept has been scientifically verified, it doesn’t support traveling into the past, like they can in Terminator. Another time travel theory involves wormholes, spacetime shortcuts that technically could allow traveling both in the past and the future. However, current research suggests that wormholes aren’t stable enough for practical time travel.
Theoretical Physics in The Terminator
What we’re learning here is that time travel isn’t straightforward. However, the Terminator movies build up a bit of hype around it. The TDE, while fictional, does foster curiosity about how time travel might be achieved. While the movies might not reveal how the TDE works, they do hint at the physical theories behind it.
One idea is the closed timelike curves or CTCs. These pathways loop back, meaning we could go back in time. However, while this might make you want to find your nearest friendly neighborhood scientist, CTCs are still just speculatory ideas, and science has yet to solve all the puzzles surrounding them.
The Multiverse Theory
Naturally, time travel comes with complications, like the Grandfather paradox. Taking an example from the Terminator universe, John Connor sends Kyle Reese back in time to take care of his mom, Sarah Connor. However, the twist here is that Kyle becomes John’s dad because of this. Without Kyle’s journey back through time, John wouldn’t exist, creating a paradox.
The Terminator also tackles the Multiverse Theory, which suggests that several universes exist parallel to one another. This means that when characters go back in time, they aren’t erasing history; they’re creating a new timeline that runs parallel to the original.
While this theory is still a vague “what if,” it does offer a cool solution to the complexity of Terminator’s timeline tangles; with the potential for multiple timelines, the series can experiment with different subplots, some of which we see in various spin-offs of the first movie. While the science might not be completely accurate in the Terminator universe, one can still dream.
Daniel fell in love with movies at the ripe old age of four, thanks to a towering chest of drawers filled with VHS tapes. Which, let’s face it, was the original Netflix binge-watch. Ever since then, this lifelong movie buff has been on a relentless quest for cinematic greatness, particularly obsessed with sci-fi, drama, and action flicks. With heroes like Nolan, Villeneuve, and Fincher guiding the way, and a special soft spot for franchises where aliens, androids, and unstoppable cyborgs duke it out (think Terminator, Predator, Alien, and Blade Runner), Daniel continues to live life one epic movie marathon at a time.
