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-----

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

nah, the reason is: when you travel back in time, our galaxy, solar system and planet are in different absolute universal positions. so you end up alone in deep space and by the time the planet reaches your position the time you traveled back has passed, making it absolutely useless and life threatening.

This is a basic fact overlooked by almost every time travel sci-fi. We wouldn't just jump into a machine and poof be in the exact same location 1,000 years ago.

It would be more like trying to land a spaceship on a planet light years away, there would have to be calculations for position and gravity. All sorts of crap before you even solve the impossible problem of turning back the clock.

Also we'd first have to figure out how to travel faster than light to even hope to break the riddle of time travel.

As fun as it is to theorize time travel would be impossibly complex and probably devastating to try.

Imagine what an object would do with all those forces behind it suddenly slamming into a object moving much slower, it would be like a time bullet that would tear apart the planet and punch a hole in space. We would likely achieve a black hole and destroy all of earth before we could see what earth looked like 1,000 years ago.

The only theory I've seen that really holds any water is time travel going forward by using a ftl loop.
