We've all heard of the twin paradox, and the idea of an infinite but finite universe, on the "surface" of a hyper-sphere and what not..(adsbygoogle = window.adsbygoogle || []).push({});

Anyways, my question is, what does relativity predict about someone who would travel all the way around this sphere? Starting at earth and ending at earth without ever accelerating? (Unless the rotation around the hyper-sphere counts as acceleration)
