A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

The reason why we never meet time travelers is because our civilization ends before the technology can come to fruition. (self.showerthoughts)

Sort of similar to the Great Filter theory, but applied to time travel technology.

I believe the only viable timeline is the one where time travel is never invented because if you create the machine to go back to prevent something happening then there is no need to create the time machine.

Which yes is an actual paradox

That's why the reason for inventing the time machine is "just in case"

Unless the time machines end up being restricted in travel only to the times after they're built. Which would resolve the paradox

Ex: The movie Primer. A good time-travel idea in a bad movie.

A great movie.

Basically everytime you go back it will make changes to the future in such way you don't exist thus the time machine by its very nature can never be discovered. Everyone that does immediately erases their future self from existence.

I've never been motivated to create a time machine, but you've suddenly made it extremely appealing...
