Radio Physics is for everyone! You don't have to be a scientist or even an aficionado to be fascinated by the questions and answers that you'll hear on KDNK. Radio Physics is a collaboration with top high school physics students from Aspen to Rifle, the Aspen Center for Physics, and KDNK Community Radio in Carbondale. Students interview one of the more than 1,000 physicists who visit the Aspen Center for Physics every year.
On this episode of Radio Physics, Sasha Fielder sits down with renowned theoretical physicist Csaba Csáki to explore the frontiers of modern particle physics.From the high-energy collisions at the Large Hadron Collider to the silent mystery of the cosmos, this interview breaks down the complex "math of the universe" into a conversation for the curious mind. Listen to Radio Physics on KDNK.org every third Wednesday at 4:30pm.

Radio Physics | Krishna Rajagopal
This time on Radio Physics, intern Henry Billinghurst talks with theoretical physicist Krishna Rajagopal, exploring one of the most extreme states of matter in the universe: “hot quark soup,” or quark–gluon plasma and how scientists recreate this early-universe matter using powerful particle colliders to briefly produce tiny droplets of this ultra-hot, liquid-like plasma. They discuss the physics of the early universe, the behavior of matter under extreme conditions, and how modern experiments help us understand the origins of everything around us. Listen to Radio Physics on KDNK.org every third Wednesday at 4:30pm.

Radio Physics | Ryan Foley
In this episode of Radio Physics, hosts Jack Kravitz and Sasha Fielder sit down with physicist Ryan Foley. The episode dives into gravitational waves, the dramatic collisions of neutron stars and the black holes they can create and how neutron star mergers help scientists measure the expansion rate of the universe, offering new clues about the cosmos’s past and its ultimate fate. Listen to Radio Physics on KDNK.org every third Wednesday at 4:30pm.
