Presenting the exclusive, YouTube video version of our full podcast episode, “Cosmic Queries Potpourri,” complete with a few glitches that got edited out of the podcast! We've got another eclectic mix of questions submitted by our fans on social media, selected by co-host Chuck Nice, and answered by Neil deGrasse Tyson. You’ll learn why the Great Attractor isn’t such a big deal anymore and how we’re searching for gravity waves using LIGO. Neil explains pressure differentials and “the bends” and what wouldn’t happen to you if you traveled between space ships without a space suit. Plus dark matter, fusion reactors, nuclear bombs, spectroscopes, black holes, spacetime, information theory and so much more. This video was shot during the recording of our episode, “Cosmic Queries: Potpourri.” If you'd like to listen to the podcast version, click here: http://www.startalkradio.net/show/cosmic-queries-potpourri/ 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!
