@divbyzero@mathstodon.xyz "Every Riemannian manifold that is topologically a sphere has infinitely many closed geodesics" If I think of the C(0) version where you have geodesics over a cube for example, then you probably get a general closed curve whenever the initial gradient is rational. For a cuboid you'd scale the set of gradients accordingly. So that seems to fit with the more general case. The word ergodic probably features in there somewhere too.
