All worlds are habitable.
Sol . I've been puzzled by how one can dwell in all the satelites, planetoids, and planets in just our own solar system. Without resorting to Newtonian Physics bending/breaking "hand-waves". My basic assumption is that technology will slow down as cultural development becomes the core concern of people in Earth, given that such a huge population in such a small planet should learn to get along and live with one another peacefully. One of the other premises is that Life support tech and radiation shielding was perfected. Anyway, Gravity was my main concern. Even with gene-therapy and advances in drugs low gravity can ravage much of how the body works over time. I was able to solve gravity problem in a High G habitable worlds like Venus, Uranus and Neptune but low gravity is a major problem for me. I find it easier to develop Satelites and Planetoids into 1G by causing it to rotate much faster, turning these habitations inside out. Solving the problem with Low G worlds like...
