In this episode, John and Chris continue their exploration of the heavens, turning to Copernicus, Kepler, and the profound transformation of our understanding of the cosmos. What begins as a seemingly simple question—why doesn't it feel like the Earth is moving?—opens into a deeper inquiry about observation, explanation, and the nature of scientific truth. Without new instruments or discoveries, Copernicus proposes a radical shift: not new data, but a new perspective. By placing the Earth in motion, he transforms what once appeared as irregularities into intelligible patterns. Subscribe for new episodes each week.
