Daniel and Kelly's Extraordinary Universe

Daniel Whiteson is a particle physicist at CERN who works on the ATLAS experiment at the Large Hadron Collider. His co-host Kelly Weinersmith is a biologist and bestselling author. Together they have this infectious energy about science that makes even the most abstract topics feel approachable. The show started as "Daniel and Jorge Explain the Universe" and has since evolved, but the spirit remains the same: two smart people who genuinely cannot stop geeking out about how the universe works. The quantum physics episodes here are particularly good because Daniel actually works with particles for a living. When he explains quantum field theory or discusses why the universe minimizes action, he's drawing on daily research experience, not just reading a textbook summary. Episodes cover everything from cosmic rays corrupting computers to the fundamental forces of nature. They drop twice a week and run about an hour, which means there's a massive back catalog of nearly 800 episodes to explore. With a 4.7-star average from over 2,300 ratings, the show is one of the most popular physics podcasts on any platform. The tone is fun and conversational but never dumbed down. They do listener Q&A episodes regularly, and Daniel's answers to audience questions about quantum mechanics are often the clearest explanations you'll hear anywhere. iHeartPodcasts distributes the show, so it's available on every major platform.
