Sam Harris speaks with Martin Rees about the importance of science and scientific institutions. They discuss the provisionality of science, the paradox of authority, genius, civilizational risks, pandemic preparedness, artificial intelligence, nuclear weapons, the far future, the Fermi problem, the  prospect of a "Great Filter", the multiverse, string theory, exoplanets, large telescopes, improving scientific institutions, wealth inequality, atheism, the conflict between science and religion, moral realism, and other topics.

Shermer and Rees discuss: existential threats • overpopulation • biodiversity loss • climate change • AI and self-driving cars, robots, and unemployment • his bet with Steven Pinker • his disagreement with Richard Dawkins • how science works as a communal activity • scientific creativity • science communication • science education • why there aren’t more women and people of color in STEM fields • verification vs. falsification • Bayesian reasoning and scientific progress • Model Dependent Realism and the nature of reality Fermi’s Paradox • why he’s an atheist but wants to be buried in the Presbyterian church in which he was raised • mysterian mysteries. Martin Rees is Astronomer Royal, former President of the Royal Society, Fellow (and former Master) of Trinity College, Cambridge, and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge. He sits as a member of the UK House of Lords. He is the author of many bestselling popular science books, including: On the Future; Just Six Numbers; Before the Beginning; and Our Final Hour. His newest book is If Science is to Save Us.

Melvyn Bragg and guests discuss the abrupt transformation of stars after shining brightly for millions or billions of years, once they lack the fuel to counter the force of gravity. Those like our own star, the Sun, become red giants, expanding outwards and consuming nearby planets, only to collapse into dense white dwarves. The massive stars, up to fifty times the mass of the Sun, burst into supernovas, visible from Earth in daytime, and become incredibly dense neutron stars or black holes. In these moments of collapse, the intense heat and pressure can create all the known elements to form gases and dust which may eventually combine to form new stars, new planets and, as on Earth, new life.The image above is of the supernova remnant Cassiopeia A, approximately 10,000 light years away, from a once massive star that died in a supernova explosion that was first seen from Earth in 1690WithMartin Rees Astronomer Royal, Fellow of Trinity College, CambridgeCarolin Crawford Emeritus Member of the Institute of Astronomy and Emeritus Fellow of Emmanuel College, University of CambridgeAndMark Sullivan Professor of Astrophysics at the University of SouthamptonProducer: Simon Tillotson
