The first time Bill Nye the Science Guy was our guest host was when Neil deGrasse Tyson was working on the COSMOS series for FOX. We now present the YouTube video version of that full podcast episode, with guest host Bill Nye, co-host Eugene Mirman and guest Astro Mike Massimino having a world of fun answering your questions, sans Neil. Bill explains how electromagnetism works, who Michael Faraday was, what NASA’s MAVEN mission will be searching for when it reaches Mars, and why you might not want to wear magnets on your wrists to improve your health. You’ll get updates on the state of 3-D printing, liquid metal batteries, carbon nanotubes and super conductivity. Find out how NASA shields astronauts from radiation, what would happen to a fish (real or Swedish) in a giant water bubble floating in space, and how spacecraft move through the void without anything to “push against.” Join the gang as they speculate on warp drives, light speed travel and teleportation. Plus, the Science Guy puts on his engineering hat to discuss the biggest challenge faced by mankind today: climate change. This video was shot during the recording of our episode, “with Bill Nye and Astro Mike.” If you'd like to listen to the podcast version, click here: http://www.startalkradio.net/show/cosmic-queries-with-bill-nye-and-astro-mike/ Support us on Patreon: https://www.patreon.com/startalkradio Subscribe to StarTalk: https://www.youtube.com/user/startalkradio?sub_confirmation=1 Follow StarTalk: Twitter: http://twitter.com/startalkradio Facebook: https://www.facebook.com/StarTalk Instagram: https://www.instagram.com/startalkradio/ About StarTalk: Science meets pop culture on StarTalk!
