Summary: This month on the Ask An Astronomer Podcast... Dan talks with Manolis and Joyce about what it means for space to be expanding and about the geometry and ultimate fate of the universe. I then ask professor Rachel Bean whether the universe is infinite and how much we can hope to learn about the universe's initial conditions. Today's podcast is written and produced by Dan Tamayo with help from Manolis, Joyce and Laura. You can ask us your own questions by visiting us at our website, curious.astro.cornell.edu.
