The Large Hadron Collider, the world's largest particle accelerator, broke down last fall soon after it was activated. It will be months before the LHC is repaired and working again, ready to smash beams of protons together. But when it is, theoretical physicist Lisa Randall has a few things she'd like to know. In this hour of Science Friday, we'll talk with Randall on the possibility of hidden dimensions in our universe, and how the LHC could help us find them. We're broadcasting this week from the campus of Florida State University in Tallahassee, as part of the Origins '09 Symposium.
