What if humanity’s future isn’t on Earth—or even other planets—but in colossal artificial worlds built in space? In this episode, we explore the O’Neill Cylinder, a visionary space habitat that could house millions, serve as interstellar arks, and transform the cosmos into a network of orbital civilizations. Join us as we dive into the design, potential, and profound societal implications of these Islands in the Sky.
