Ask Lemmy

The world has yet to notice me traveling one day into the future every 24 hours.

Going back a few hours and getting some more sleep sounds nice

Rewind the last 15 seconds of a meal to enjoy the last bite again.

Let's just say no one's noticed anything yet

"Alright, it says my microwave meal takes four minutes..."

Instead of rewinding the video, just rewind causality.

And when you skip ads you really skip ads.

Watch Primer, that's the whole point of the movie, how a couple of engineers who discover time travel try to profit from it while causing the least impact possible.

Also easily my favorite time travel movie by a long shot, and I'm a time travel movie fan.

Time travel to 12 hours ago so I can get more sleep

Future time travellers going back in time to the moment the first time machine was invented to figure out how that one worked because in the future theirs suck and are locked down to prevent abuse.

Anthropology while cloaked, as the Temporal Prime Directive requires

Going forward three days to when it's $2 beer night at the bar.

We are all travelling through time right now with very little impact.

Yes I know, I suck.

Cheap and easy food storage.

Make a dozen extra servings of whatever I'm cooking and just leave it in the pot on the stove. When I'm hungry in the future I'll come back and serve myself up another bowl. When I take the last serving, I leave a note saying when I came from so I know to prepare another batch by then.

Go back in time and prevent your time machine from working.

Nice tight little loop. Minimal interference, hopefully.

By doing it in the vastness of empty space.

Going forward at all seems less harmful than going back, but perhaps more dangerous.

I am seeing this comment right after I finished 'Life is Strange'...

Traveling a second back in time to scratch that itch before it even happens. Maybe going back in time to tell yourself not to order that taco bell. Skipping forward in time to skip a hot pocket cooking in the microwave. Traveling a couple of minutes into the future to skip a boring conversation with the officer that pulled you over.

Here's the real question, if it's possible to time travel isn't it just part of the timeline even if it doesn't seem like it. If you could traverse forward and backwards in time like a tape deck isn't it already laid out including all of the time traveling you'll ever do.

Go back in time and fill the lottery, but don't check the winning numbers before going back.

Going massive events that are either completely void of people or full of people.

Star exploding? No one around, nothing to change.

Parade for the astronauts coming back from the moon?

What's another guy standing around, just minding my own business.

If it were ever possible, I'd say, just as an observer. There are lots of things I'd love to experience for the first time again but I personally have little desire to change the past.

Travel forward in time to when the shower is warm.

Going forward.

To me the rules of time travel are that it is time travel only. Go forward or back more than a few seconds and you'll find yourself floating in the vacuum of space rapidly dying as the earth, the galaxy and the universe continues moving.

Depends on which model of time travel you subscribe to.

If you're working under "Back to the Future" logic, then the best way is to not use time travel at all. Butterfly effect and all that.

If you're working under "Avengers: Endgame" logic where you're actually in an alternate reality, then you could muck around a bit without destroying your own "present" though you would be meddling with the destiny of that parallel universe (assuming you subscribe to the Prime Directive, that would be a bad thing).
