    Not necessarily. Curved or warped does not imply spherical. In a cylindrical
    universe you can follow a geodesic forever without ever coming back.

    On a spheroidal earth, if you proceed on a rhumb line with constant speed, you
    will arrive at a pole after a finite time. You won't be able to stop your vessel
    at this very moment, because of your inertia . This raises the puzzling
    question: Where will you be a second after you will have passed through the
    pole? Neither Dutton nor Bowditch has the answer.
