  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.

      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?

        Is this a time machine or a star-trek space ship? This thing keeps changing
