    I don’t even know what this conversation is about anymore.

    It’s about how a theoretical time/space machine would navigate obeying current physics knowledge.

    You wanna go inside a gas giant now?

    I’d like the option. I’d certainly like to land on planets with liquid cores.

    How about this. When you develop timetravel through space in all dimensions to “jump” anywhere at any time. Let us know.

    Nah. Let’s design the solution now so it’s ready to be used when needed.

      When developing. You solve one problem a time. So you don’t spend time trying to calculate rotation from gravity.

      The beauty of a time machine on earth. Is that we can imagine most of it, and add the time travel part with our imagination to make it “plausible”

      You want to add instant teleportation to any point in space at any time, while knowing everything about every planet and star including their location. Instantly.

      I have a magical spell that already does everything you want. It’s called “goannoyium-someoneelsium-fuckwad”.

      I already solved your little problem

        Teleportation is not being added by me. It’s the topic of this entire thread. Even calculating the rotation of just the earth at other points in time is not trivial because Earth has an unobservable liquid core.

        No. You didn’t.

            Did we? The inner core maybe, but there’s definitely some liquid somewhere, cos of volcanoes.

            It’s not something that is currently predictable though. We don’t have decent models for the magnetic field.

                The inner core is solid. The outer core is 2000km of liquid.

                But the main point is that both of these layers could vary their spin, making long term predictions about the rotation of the crust inaccurate.

          I did. The spell puts anyone anywhere at anytime. And it works by whatever exact imaginative solution that doesn’t exist you want. Pretty cool huh.
