    Teleportation. Unless truly instantaneous, you need to account for the fact that the earth moves 18 miles per second relative to the sun.

      And isn’t the solar system moving at like 500000 miles an hour around the milkyway too?

      Teleportation and timetravel both have this issue where you have to take a fuckload of moving parts we don’t even completely understand yet, into account.

        Time travel would have to imply teleportation as well. If teleportation is actually instant or ftl, it would also be at least some level of time travel as you would be able to move outside your causal envelope.

      Inertial systems are all equal in a certain relevant here sense, if there is no need for account for your movement relative to Sun, Galaxy, CMB, or anything else. Yes, in this sense, Sun also rotates around Earth.

      On top of that you need to account for the fact that the earth’s surface is moving at different speeds depending on latitude and elevation. Even if you can do the calculations to hit your mark, there is most likely to be some energy mismatch that needs to be accounted for.

      This doesn’t make sense. The earth moves at very different speeds depending on what you compare it to. The only thing that makes sense is for the teleportation to be relative to the teleporter. Maybe it would still require taking into account rotation, instead of linear momentum. idk, still seems complicated.

        But if it takes time, there’s a moment where you’re not there, and thus, the reference is lost.

        Instant teleporting no problems though. I would even be okay with nightcrawler/Minecraft nether-like teleport where you travel through another locked in dimension.
