Podcast: The Infinite Universe

Is the universe infinite? Or is it confined to a finite amount of space? Is it shaped like a donut, or does it stretch on forever as an infinite plane? A lot of people wonder about these questions, and a few people are actually trying to answer them. Like astrophysicist and cosmologist David Spergel of Princeton University. He and his colleagues are looking for clues about the shape of the universe, because they think it could help them determine if the universe is finite or...something else.

Listen to this week's podcast to hear Spergel talk about why even some cosmologists find "infinity" to be a tricky concept, and what they're doing right now to try and find the end of the universe.
