Science & Futurism with Isaac Arthur
Science & Futurism with Isaac Arthur explores humanity’s long-term future through space exploration, advanced technology, and big-picture science. Hosted by National Space Society President Isaac Arthur, each episode uses real science and careful speculation to examine space colonization, megastructures, artificial intelligence, post-scarcity economies, and the physics shaping civilization beyond Earth.
