Here are questions that give a cosmologist \u2013 and maybe even you \u2013 insomnia: What happened after the Big Bang? What is dark matter? Will dark energy tear the universe apart?\nLet us help you catch those zzzzs. We\u2019re going to provide answers to the biggest cosmic puzzlers of our time. Somewhat. Each question is the focus of new experiments that are either underway or in the queue.\nHear the latest results in the search for gravitational waves that would be evidence for cosmic inflation, as well as the hunt for dark matter and dark energy. And because these questions are bigger than big, we\u2019ve enlisted cosmologist Sean Carroll as our guide to what these experiments might reveal and what it all means.\nGuests:\n \n\u2022\xa0\xa0Sean Carroll \u2013 Cosmologist, California Institute of Technology\n\u2022\xa0\xa0Jamie Bock \u2013 Experimental cosmologist at the California Institute of Technology and NASA\u2019s Jet Propulsion Laboratory and a member of the BICEP team\n\u2022\xa0\xa0Brendan Crill \u2013 Cosmologist at NASA\u2019s Jet Propulsion Laboratory and member of the Planck collaboration\n\u2022\xa0\xa0Jeff Filippini \u2013 Post-doctoral Fellow, California Institute of Technology, assistant professor of physics at the University of Illinois and member of the Spider team\n\u2022\xa0\xa0Neil Gehrels \u2013 Astrophysicist at NASA\u2019s Goddard Space Flight Center, project scientist for WFIRST\nLearn more about your ad choices.
