I think gravity is the solution to this problem. The time machine just has to be able to lock on to the earths gravitational force from across time
Can you detect rotational velocity using gravity?
Earth rotates at about 460m/s around it's own axis.
and I'm sure scientists have access to a more precise number than that.
we dont have to detect what we can calculate
We have a machine that can track planets through time and space and you only want it to work on Earth?!?
Why would it only work on earth? How do you think we took close up pictures of pluto?
It would only work on earth because we've only given the time/space machine information about the rotation of the earth.
But my question is more about science theory than fiction. Does observing gravity give any information about how fast that mass is rotating?
"It would only work on earth because we’ve only given the time/space machine information about the rotation of the earth."
So you're the one that only wants it to work on earth then.
And no. "Observing" Gravity does not give any information of how fast an object is spinning around it's own axis.
So you're the one that only wants it to work on earth then.
No. Are you suggesting we supply this machine with the rotational velocity of all planets in the known universe? Or some other solution?
How could we jump to a planet on the other side of the galaxy?
