If a time traveller posts a video from the future (of say some famous person giving an interview), it probably would appear to us as if its an AI generated video of the said person.

    Given that AI exist and time travel does not, that would be the logical conclusion, yes.

        Indeed. But sending a video back from the future would require backwards time travel and that one doesn’t exist.

            Doubtful. It’s not compatible with the current laws of physics and would break causality. Also some of those potential future time travellers should have shown up by now.

              Causality is just determinists starting with “time travel is impossible” and finding a fancy name for it.

              I don’t want to say they’re wrong, just that asserting casualty in a discussion about time travel being impossible is kinda like asserting Godwin’s Law in a discussion about whether or not Trump’s a nazi.

                No … it doesn’t. Slowing the passage of time is not the same as going backwards in time.

      Relativity would like a word with you.

      We don’t know if the conditions that allow for into the past time travel can form naturally. But math as far as we know it, does allow it.

      Traveling to the future at different speeds is well established on small scales. Astronauts in orbit arrive in the future having experienced an insignificant amount of time less then we do.
