Gravity has always shackled industry, but orbit frees us to build in ways Earth never allowed. This episode explores the rise of orbital foundries and the industries they unlock. Support us on Patreon: https://www.patreon.com/IsaacArthur Support us on Subscribestar:...
Semiconductors built in orbit are already outperforming Earth-made chips. Space Forge and United Semiconductors just proved zero-gravity manufacturing could change computing forever. Join this channel to get access to perks:...
3I/ATLAS is only the third interstellar object we’ve ever seen — but could it really be an alien artifact, or just another comet with unusual traits? Watch my exclusive video The Economics of Immortality:...
Could life thrive in seas of methane instead of water? We explore Titan-like worlds and the alien ecosystems they might harbor. Watch my exclusive video The Economics of Immortality: https://nebula.tv/videos/isaacarthur-the-economics-of-immortality Get Nebula using my...
Space isn’t just for lonely colonies—it’s for communities. Join us as we imagine constellations of space habitats bound by tethers, trade, and trust, building not just homes in the stars but entire civilizations. Watch my exclusive video The Economics of Immortality:...
NASA’s Perseverance rover may have found the best hint yet of Martian life — strange minerals in Jezero Crater that could be microbial fingerprints… or just clever geology. Visit our Website: http://www.isaacarthur.net Join Nebula: https://go.nebula.tv/isaacarthur...
Feudalism once ruled Earth—could it rule the cosmos too? We dive into the strange but plausible world of space nobles, orbital dukes, and knights of the vacuum clad in power armor or piloting mecha. Watch my exclusive video The Economics of Immortality:...
You’ve made it to a new world—but how do you make a living when Earth is light-years away? We chart how colonies bootstrap markets, money, and meaning—from scrip and rationing to trade networks and post-scarcity systems. Watch my exclusive video The Economics of...
Space hates glass: every extra window is a liability when even a grain of dust at 0.1c has the energy of TNT. Let’s bust the skylight myth and see why real starships will be armored, not panoramic. Join this channel to get access to perks:...
What if the end of everything came not from cosmic fate, but from us? This episode examines the physics, probability, and peril of experiments that could, in theory, unravel the universe. Watch my exclusive video The Economics of Immortality:...
