In this episode, Matt opens with forgotten space hero John Bevis’ birthday and a cosmic musing on relativistic dust, black holes, and the unimaginable energies hidden in tiny things. Then astrophysicist and author Ethan Siegel joins the show to discuss his new book, The Grand Cosmic Story, a sweeping journey from the birth of the cosmos to the emergence of life and intelligence. Together they explore the importance of critical thinking, evidence, and scientific honesty in an age when misinformation moves faster than light itself.
