Ring Worlds, Spin Gravity, and the Limits of Megastructures
Episode 33
Monday, 26 January, 2026
Planets are a historical accident. Ring worlds are what you build once you understand physics well enough to stop settling for spheres.In this episode of Entropy Rising, we break down rotating space habitats from the near term to the absurdly large. We start with practical designs like Stanford tori and early ring stations, then scale up through Bishop rings and Banks orbitals, all the way to full Niven style ring worlds that rival planetary orbits.We dig into how spin gravity actually works, why small habitats make people sick, where material limits appear, and which designs collapse under their own physics. We talk atmosphere retention, day night cycles, weather, oceans, radiation shielding, and why most sci fi depictions quietly ignore stability problems that would tear these structures apart.This is not a hype episode. Some ring worlds are plausible. Some are only possible with exotic materials or active stabilization. Some probably never work at all. The interesting part is understanding where each design breaks and why.If you want to know which megastructures are realistic, which ones are fantasy, and why cylinders may beat rings in the long run, this episode is for you.Support the showWebsite: https://www.entropy-rising.com/
