If the machine has the ability to jump in time and space (needed to land in the same spot) then it would be a real waste to use it only on earth.
So we would need a mathematical model of the entire universe that is accurate to the metre over all time. This N body is much harder than the 3 body problem.
Or we use gravity and other methods to track relative stationary position.
So, what other methods can be used to determine rotation?
So all travels to new planets require 2 jumps. One to get near and measure the rotation, and one to actually land. I’d prefer something more efficient.
Also there is the assumption that the surface rotational velocity is constant over time. This is only true for solid planets without gas or liquid centers. Insides can spin at different speeds than the surface.
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”.

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.

I already solved your little problem
We know the rotational speed, but this time machine wouldn’t.
And is there a reason you couldn’t program that data into the machine?
Doesn’t that sound like something you’d need? Along with a mathematical model of how earth orbits the sun?

Jesus fucking Christ. We can still calculate the rotation of a body like we normally do.
You observe it. Wait 1 seconds. Observe it again. And the delta in position is your rotational speed per second.
That is the method. The only one

I don’t even know what this conversation is about anymore. You wanna go inside a gas giant now?
How about this. When you develop timetravel through space in all dimensions to “jump” anywhere at any time. Let us know.
It’s about how a theoretical time/space machine would navigate obeying current physics knowledge.
I’d like the option. I’d certainly like to land on planets with liquid cores.
Nah. Let’s design the solution now so it’s ready to be used when needed.

No. You didn’t.
