  It’s not like we actually know how time travel would work. Because, you know, it’s not currently a thing at all.

    I think that it’s fairly settled theory that if you perceived it it happened. If you went back to the past and caused it not to happen then it wouldn’t have happened and you wouldn’t have perceived it. Basically, you can’t change what already happened because whatever you did in the past had already happened when you perceived and therefore nothing that you did changed anything.

      Not at all. There is many ways to rationalize time, nothing is settled at all. The “settled theory” you talk about would create paradoxes, if time travel is ever made real. And paradoxes don’t work well with reality.

      There is actually a fairly common way to rationalize time that is the opposite of what you’re describing: Time is entirely a construct, there is no past, no future, only the present. Take away all of humanity’s memories and the last doesn’t exist at all.

      There’s also an understanding of time that says it only goes forward, making time travelling to the past impossible.

        If you don’t like something that happened to you today and go back to 2000 to change something that change that you made in 2000 had already occurred in 2000 when the thing that you didn’t like happened in 2025. What happened in 2025 happened after the change you made in 2000.

      Time travel is a settled theory?

      😁

      That’s not what theory means at all

      So if I leave my phone in 1929, nothing changes? That’s absurd.

        If you left your phone in 1929 then you had already done it in the past today. Nothing changed.

  Time is a one-way linear progression, you can’t go back in the first place. Any fictional story where time travel happens necessarily has its own rules, and all interpretations are equally valid

    I don’t think that space time works like that.

      that’s a bold assertion. prove it.
