Here are questions that give a cosmologist – and maybe even you – insomnia: What happened after the Big Bang? What is dark matter? Will dark energy tear the universe apart?
Let us help you catch those zzzzs. We’re 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.
Hear 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’ve enlisted cosmologist Sean Carroll as our guide to what these experiments might reveal and what it all means.
Guests:
•   Sean Carroll – Cosmologist, California Institute of Technology
•   Jamie Bock – Experimental cosmologist at the California Institute of Technology and NASA’s Jet Propulsion Laboratory and a member of the BICEP team
•   Brendan Crill – Cosmologist at NASA’s Jet Propulsion Laboratory and member of the Planck collaboration
•   Jeff Filippini – Post-doctoral Fellow, California Institute of Technology, assistant professor of physics at the University of Illinois and member of the Spider team
