Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.If this question can be reworded to fit the rules in the help center, please edit the question.

Honestly, I haven't a clue what your question is about. Would you please care to clarify what you mean? Thanks. – TildalWave Oct 16 '13 at 16:53
@TildalWave I interpret it in terms of curvature - i.e. "How is the universe curved?" I think that would be a duplicate of something, though. – HDE 226868 Sep 30 '14 at 1:33
@HDE226868 It would take about one minute off OP's time, and about 20+ minutes off each attempting to answer it whilst not being sure about its nature. I'd suggest that the former is the better option. ;) – TildalWave Oct 1 '14 at 14:34

I think it's useful to realize the meaning of "shape" is not the same as in "what is the shape of this object I'm holding." Because we are a part of the universe, "shape" is about how things work (eg, how light moves through the universe), rather than "is the universe a sphere, cube, hypersphere or some other 'shape'."

This question is probably too broad to be answered here. I suggest reading the WikiPedia article on the 'Shape of the Universe'.
