In this episode, Heather and Liz talk time travel in entertainment (but not real science, so don’t tell us we don’t know science – because we already know that).
We are discussing time travel in TV and movies. Since we don’t have Dr. Neil Degrass Tyson on the show (but we would LOVE to), we won’t be talking the actual physics/science behind the potential for time travel, or even things like wormholes. We are sticking to what we can Google and what we can see in entertainment.
Time Travel Theories
- Fixed timeline – Single fixed history which is unchangeable. Whatever you go back and try to change will be what created it in the first place. Examples: 12 Monkeys and Donnie Darko.
- Dynamic timeline – Very small change in the past has a huge impact on the future (Butterfly effect or chaos theory). Example: Back to the Future. Paradox: Grandfather paradox – If you go back in time and kill your grandfather and thus you should never be born, but the fact that YOU went back in time means that you existed and the grandpa can’t be killed.
- Multi-verse – Every change you make creates a new timeline. Example: Doctor Who, The Flash
- Trapped in time – Time is paused and they will rejoin the timeline. Example: Jumanji, Austin Powers: The Spy Who Shagged Me; Planet of the Apes (1968).
Bootstrap Paradox: occurs when an object or piece of information sent back in time becomes trapped within an infinite cause-effect loop in which the item no longer has a discernible point of origin, and is said to be “uncaused” or “self-created”.
