What would be the least impactful way of using time travel? (lemmy.world)

Started as a shower thought (literally in the shower), but decided to make it more open-ended.

My answer to this would be "watch future seasons of anime that I am waiting on".

I don't see how that could cause a huge ripple through time.

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).

Or the Bill & Ted's time travel where any changes you make were supposed to be there in the first place so you didn't really change anything.

Good catch. I forgot about the "closed, timelike curve" model
