How much sunlight can I get into my O'Neill cylinder and how much light needs to be artificial? The cylinder is 32 km long in total, 8 km in diameter, with 3km long endcaps, resulting in a habital area with a length of 26 km (= and an area of cirka 754 km2). The main body of the cylinder is buried within a small asteroid with a diameter of roughly 26 km. The end caps are windows into space i... (more) |

Is it possible to have multiple different climates within one O'Neill cylinder? The illustrations of O'Neill cylinders I have come across with so far allow unrestricted view through the whole tube. Some are more playful with topography but still, there is a visible end. Are there reasons that forbid to close off parts of the tube, lets say, by a wall of mountain? I would like... (more) |

Could a new planets plane be at a different degree as the other planets in our solar system? I read this and wonder now, what if we would introduce a new planet to our solar system; would the force of gravitation demand a similar plane as that of the other planets? Mercuries 6.3° indicate that a tilt is possible to some degree, but there are obviously limits. Would the plane of a new plan... (more) |

Explain the rotation and positioning of O'Neill cylinders to me I have seen Isaac Arthurs video of O'Neill cylinders and read through many descriptions, but it still is not clear to me how exaclty the two counter-rotating cylinders are placed in regard to another and in regard to the sun. I sort of imagined the cylinders to connect on their short site, when I fi... (more) |

Which place in our solar system is the most fit for terraforming? Far in the future technology has evolved to the point that humanity is able to try and terraform something in our solar system. The moon is out, since it's too close to earth and therefore to risky, since we don't want any debris raining down on our home (assuming we use techniques like dropping com... (more) |

How big an area can we possibly make habitable on the moon? This question focuses on an artificial atmosphere on the moon and the achieved amount being the limiting factor for the size of habitats. I got a lot of beef for the suggestion to terraform the whole moon in the style of omg-the-amount-of-energy-needed-for-that, and apparently no ones believes we ca... (more) |

Would this setup of a terraformed moon hold up? [Edits added in italic] BACKGROUND A few thousand years from now the moon has become one of many habitable places in the solar system. Economy, constant growing knowledge and human will made drastic technological progress possible. Early on people sat up moon bases and mines and flourishing trade ... (more) |

What would the temperatures on a terraformed moon be like? In the far future the moon is terraformed and maintains earth-like conditions for people to walk around freely. Gravity is a 6th of earth's. We assume the atmosphere is "well-functioning for human beings" and kept so by permanent maintenance. What would the temperatures be like? Things to consider... (more) |

Imagine a well functioning atmosphere on the terraformed moon Just assume we are long into the future, all other parameters have been met and we have the technology, will and money to terraform our moon and keep it so. Atmosphere, as commonly agreed on, would over time disappear, but that's not an issue as there is a constant, well-functioning industry establis... (more) |
