Katherine Freese

Katherine Freese, theoretical physicist and cosmologist who studies dark matter and dark stars, joins to explore the dark universe. She explains paleo detectors that use ancient rocks, why xenon sits in underground labs, and how JWST findings relate to dark energy. Topics include WIMPs, axions, primordial black holes, dark stars, modified gravity, and detection strategies.

Dr. Katherine Freese, a theoretical astrophysicist from the University of Texas at Austin, explores the controversial concept of 'dark stars,' which may have existed in the early universe. These massive stars, powered by self-annihilating dark matter, could outshine current stars. Dr. Cosmin Ilie discusses how the James Webb Space Telescope has captured potential evidence through observations of 'red dots' and critical helium absorption features. The conversation dives into how these dark stars could seed supermassive black holes and challenge existing theories of star formation.

Theoretical physicist Katherine Freese discusses dark matter, dark stars, and the potential link to JWST’s discoveries. They touch on the mysteries of dark matter particles, neutrino discovery, and the role of dark matter in shaping the universe. Also explored are dark stars fueled by dark matter and the idea of black holes creating dark matter themselves.
