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.

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.

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.

From O’Neill cylinders to spiral habitats, discover how humanity might build colossal, interconnected cities high above Earth.

From abiogenesis to AI, we rank the top Great Filter candidates and test them against the data to see which best explains the Fermi Paradox. Is the universe empty, or just dangerous? We explore ten filters—cosmic, biological, and civilizational—that could silence civilizations before they spread.

We often contemplate superintelligent entities, and advances in AI and human mind augmentation may soon bring them about. But how big could they get? What would they think about? And might you, or I, one day become one ourselves?

What happens after intelligence explodes beyond human comprehension? We explore a world shaped by superintelligence, where humanity may ascend, adapt — or disappear.

Before we build cities among the stars, we’ll need factories on the Moon. Discover how lunar industry could kickstart a space-based economy and reshape the future of humanity.

The silence of the stars might be hiding more than an absence of life — it might conceal ancient machines, monuments, and traps from civilizations long vanished. Today, we explore these eerie cosmic echoes and the risks of unearthing them.
