Theory: time is immutable, and the universe exists as a single timeline that repeats itself through a high-dimensional recursive or map-reduce. By “time travel,” you are essentially moving yourself across loops and jumping to a different iteration of this universe.
Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, and toxicity are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !askusa@discuss.online
Reminder: The terms of service apply here too.

I have a unified theory that includes bits of everything.
- it's possible to communicate in the same timeline between the future and past by using gravity (think something like Interstellar)
- By using gravity as an nondestructive line of communication, it's possible to change events in your current existence without a causal shift or split.
- by sending actual matter into a timeline either ahead or behind where it's supposed to exist it causes a causal shift or split in the timeline. this means you will never be able to see the future and can only contaminate the past enough to damage your present causing an inverted negative effect to your going back in time anyway.
- nexus events can only exist when it has a high gravitational marker attached to it. eg: a star will always go supernova, when doesn't matter as much as the fact that it's unstoppable because the gravitational function it applies on a universal scale across all timelines, known and unknown. think of it like flashing a flashlight into a room filled with mirrors. each mirror is the physical plane of existence for the timeline (the beam of light). the beam will hit the first plane and then bounce off all the others in the order in which the photons scatter. if you could slow down and witness the photons, they wouldn't all hit at the same time nor at the same strength.
- It's only possible to communicate across time using gravity and only if someone has picked up the "receiver" in the past. meaning if we're not listening for the call "now", we will never receive the call from "tomorrow". I think this type of communication is completely within the reach of our technology today and quite possibly is being used today without world knowledge.
Either 1 or 3. I tend to lean towards 3
Stories involving 2 are often the most fun, as well as 4 if they aren't lazy with the timeline corrections
1 feels the simplest and I would prefer it. With 3, unless the technology is limited to a few people, it's going to get messy
Whichever is closest to science and physics.
It'd be a horrifying thought if the time travel theory you believed in was different to what you got, UGH just the thought gives me existential dread.
This also reminds me of:

Time travel will never have any effect on anything.
