Hurkyl's thread on why it is useful to study curved spaces as well as some discussions with a friend have led me to pose this question:
There is a current theory that the universe could be torus shaped because the intrinsic curvature of a torus would be zero, much like that of a flat space. Currently there are observational studies underway to try and determine if there are signature repetitions in the sky that would indicate light has made a curcuit around the universe. Such an idea is possible in theory, but I'm interested in debate on the subject of the implications if the universe turns out to be a torus shaped object, or if there are possibilities for other objects with zero intrinsic curvatures that could be a possible shape of the universe.
On a side note, I posted this topic in this forum because it is a cosmology issue, and even though it is theoretical, it is not so much of the same breed as M-theory or LQG for example.
