Nope, not visiting that
(thelemmy.club)
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
This is a science community. We use the Dawkins definition of meme.
That all depends on what time travel theory ends up being correct. There's the one where it's all the same timeline, and there's the one where you spawn a new universe by traveling back and making changes.
So, a person traveling back might not be impacting the future they left.
It would be a real bitch to try and coordinate a party with multiple time travelers with the forking system. Each one might end up as the only traveler in their new universe. Unless they carpooled, I guess.
