Science & Futurism with Isaac Arthur

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.

    The Physics of FTL Travel

    Can humanity ever travel faster than light, or does every shortcut through spacetime break causality itself? We explore warp drives, wormholes, tachyons, and why the universe pushes back.
