Im doing a project this yr on the title in the subject and i have been struggling to find imformation on this problem when using a PERIODIC universe. It would be very useful for me in anyone can post any links to websites/acrobat reader docs regarding this.(adsbygoogle = window.adsbygoogle || []).push({});

I have found one where the unverse was modelled as a cylinder and the twin paradox used on it where twin A stays at home so travels straight up the cylinder and twin B travels around the cylinder and eventually crosses twin A's path. so anymore examples like this would be great

Topics to be considered are:

*How can special relativity be formulated in a universe in which a spatial dimension is periodic (ie cylinder)

*twin paradox: What do the clocks of these two inertial observers show at each pass?

*Two general inertial oberservers:

*One inertial observer and light rays:

Thanx in advance
