Given a closed Riemannian manifold, a point P on it and a nonzero vector V in its tangent space, can you extend a geodesic in that direction of V indefinitely? I count looping back onto itself as "indefinitely".(adsbygoogle = window.adsbygoogle || []).push({});

The theorem I have in my book only guarantees that this is possible locally near P.
