George Church & Avi Loeb | Origins & Futures: Life, the Cosmos, and Beyond

What sparks the emergence of life in the cosmos, and where might curiosity lead us in the future? In this premiere episode of Curiosity ⇔ Entangled, Avi Loeb, astrophysicist and Baird Professor of Science at Harvard University, joins George Church, pioneering geneticist and professor at Harvard Medical School, for a fascinating dialogue on the origins of life and the possibilities for humanity’s future. Their conversation spans from the Big Bang to panspermia, synthetic biology, and the existential risks and opportunities that define our place in the universe. With curiosity as their guide, these two visionary thinkers explore profound questions about science, survival, and what lies ahead. Curiosity Explored: 1. How the chemistry of life could have started in regions enriched with heavy elements shortly after the first stars formed. 2. Whether life on Earth could have originated on Mars, delivered here through meteorite impacts billions of years ago. 3. The possibility of mirror life being suppressed by terrestrial life and why we might not recognize alien life among us. 4. The hypothesis that extraterrestrial “gardeners” seeded Earth with self-replicating probes to create life as we know it. 5. Humanity’s future, from augmented brains and the fight against aging to escaping Earth’s eventual demise through space exploration.
