About this episode

Mario Livio discusses Galileo’s scientific legacy and its relevance to modern science and truth.

What can Galileo still teach us about science, truth, and discovery? In this conversation, Mario Livio discusses Galileo’s scientific legacy, the Hubble Space Telescope, science denial, exoplanets, cosmology, and the future of life in the universe. Drawing from his book Galileo: And the Science Deniers, Livio explores Galileo’s role in the development of the scientific method and examines how scientific understanding evolves through observation, experimentation, and self-correction. Mario Livio is an astrophysicist and author who worked for 24 years at the Space Telescope Science Institute, which operates the Hubble Space Telescope.
