You come back around on a sphere too, e.g. traveling by the equator.
- somab 7y agoIn that case you would be traveling a curved path so there would be acceleration even if your speed remained constant.
- badosu 7y agoIsnt a torus curved? What's the argument?
- somab 7y agoIf you use toroidal boundary conditions then you could remain in an inertial reference frame and return back to the same pont. See https://en.m.wikipedia.org/wiki/Periodic_boundary_conditions https://en.m.wikipedia.org/wiki/Periodic_boundary_conditions
