Science & Futurism With Isaac Arthur

Magnetic monopoles are hypothetical particles with a single magnetic charge — north without south. Predicted by grand unified theories, they may be incredibly massive and could bind together into “magmatter,” an ultra-dense material stronger than anything known in nature.Get Nebula using my link for 50% off an annual subscription: https://go.nebula.tv/isaacarthurWatch my exclusive video Settling Saturn's Rings: https://nebula.tv/videos/isaacarthur-settling-saturns-rings-exploring-the-origins-resources-and-future-habitats-of-a-halo-worldCheck out the Nokia 3310 CT Scan: https://nebula.tv/videos/realengineering-the-anatomy-of-the-nokia-3310?ref=isaacarthur

The most expensive part of space travel isn’t the fuel—it’s the cargo. Additive manufacturing isn’t a sci-fi magic trick; it’s the key to building shipyards and telescopes at scales rockets were never meant to handle. We aren't just launching ships anymore; we're moving the factory to the void.Get Nebula using my link for 50% off an annual subscription: https://go.nebula.tv/isaacarthurWatch my exclusive video Settling Saturn's Rings: https://nebula.tv/videos/isaacarthur-settling-saturns-rings-exploring-the-origins-resources-and-future-habitats-of-a-halo-worldCheck out Practical Engineering: https://nebula.tv/videos/realengineering-the-anatomy-of-the-nokia-3310/?ref=isaacarthur

Why does the galaxy seem silent? Maybe aliens aren’t rare—maybe humans are.

Is science nearing its limits? We explore whether humanity could ever run out of discoveries—or if the universe guarantees endless questions, deeper mysteries, and new frontiers forever.
