O'Neill

O'Neill refers to the O'Neill cylinder, a theoretical space habitat proposed by physicist Gerard K. O'Neill. It is envisioned as a massive, rotating space station that creates artificial gravity through centrifugal force. Designed to support human life, it would have its own Earth-like environment, including atmosphere and ecosystems, allowing for sustainable living in space. The concept aims to enable large-scale human settlement beyond Earth, addressing overpopulation and resource limitations. While still theoretical, the O'Neill cylinder represents a visionary approach to future space colonization, emphasizing practicality and self-sufficiency in extraterrestrial habitats.
