   If 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

   In that case you would be traveling a curved path so there would be acceleration even if your speed remained constant.

   I think the question you are asking is what if the universe is toroidal. What if you traveled so far you came back around.
