To need air is human. Our lungs thank us for each breath we take. But air is more than a transporter of O2. It shapes our weather, keeps birds aloft and moves spores from here to there. A cubic foot of air is anything but “empty” (hot dog grease particles, anyone?).

The same goes for space (minus the hot dog grease). It’s a happening place. Discover why interstellar space is more than a whole lot o’ nothing; and what happens when the Voyager spacecraft leaves our solar system. Plus, catch a skydiver in action!

Guests:

   Mako Igarashi – Skydiving instructor, Skydive Hollister, Hollister, CA

   Rhett Allain – Physicist at Southeastern Louisiana University, blogger for Wired.com

   William Bryant Logan – Author of Air: The Restless Shaper of the World

   Robert Wagoner – Emeritus professor of physics, Stanford University

   Alex Filippenko – Astronomer, University of California, Berkeley

   Ed Stone – Physicist at CalTech, former Director of the Jet Propulsion Laboratory, project scientist for the Voyager mission
