What's the shape of our universe?

“Dr. Dave Goldberg — Is the universe flat or spherical or saddle-shaped, and what do any of these things really mean? Do we live in a Pac-Man universe, or an infinite one? In this week's "Ask a Physicist" we'll find out.”

Recently io9 posted an interesting and mind boggling question: “If you keep going around the universe will you end up where you started?”

A very interesting read. Link to the article.
