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 8 hours ago

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'.
