Could an autotrophic civilisation develop, or will evolving life forms always eat each other? I can imagine our own civilisation becoming autotrophic eventually, if biological life gives way to a population of machines that need only sunlight. However, the history of that situation still involved a long period of organic life forms eating each other. So my question is about an organic evol... (more) |

A realistic road network Given a map showing terrain and settlement locations (cities, towns, villages) I'd like to design a road network that appears natural, rather than just being the most efficient. I'm interested in two aspects: how can I realistically model the development of roads over time? will a road network natu... (more) |

How long does terraforming take if you have to build the planet from asteroids? I'd like to set a story in our solar system with Earth and the inner planets becoming uninhabitable and a new planet being required. If human beings decided to build a world by making slight deviations to asteroids in the main asteroid belt, trojan asteroids, and Kuiper belt until they start to coale... (more) |

Maximum Earth population by wiping out biological life I want to create a world set on our Earth but with humans converted entirely to machines, so the population can be larger than would be possible with biological humans. In contrast to biologically shrinking humans, as the population increases they transfer their minds into machines that can sustain ... (more) |

Maximum Earth population given biological shrinking I want to create a world set on our Earth but with humans shrunk down as much as possible to allow a huge population. As the population increases they genetically modify their bodies to be as small as possible while retaining human intelligence. They do not replace their bodies and minds with machin... (more) |

Ethical solution to generation ship where new generation want to go home I can easily set a story in a dystopian environment not subject to ethics, but I would rather try to create a backdrop that is as ethical as possible given the requirements. I feel that writing about possible deviations from an ethical starting point will give more interesting insight into human inte... (more) |

How can I estimate how far into a cave network breathing is possible? I want two populations to coexist in a world with extensive tunnels carved into the rock. One population lives in the tunnels, coming out to trade and gather food. The other is aware of the tunnels but is wary of entering them. I want the tunnels to go far enough that after a certain point there is ... (more) |

City in a hollow tree As a tree grows new layers are added each year so that the trunk expands in radius. The living part of the tree is a relatively thin layer on the outside just beneath the bark, and the wood further inside is dead, just there for support. In trees that live long enough, some of the dead wood (heartwoo... (more) |

A: Does living without access to sunlight for extended periods have known physical or psychological effects on humans? Physical health Sunlight is popularly regarded as beneficial due to the production of vitamin D, but also popularly regarded as non essential since vitamin D can also be gained from diet or supplements. However, the process of producing vitamin D uses up specific raw materials. Those materials, if n... (more) |

Are infections necessary for human colonisation? If a human colony is set up on another planet or moon, or in an orbiting habitat, most of the infectious diseases from Earth would not be present in the small initial population. Careful screening could further reduce the number of infectious diseases introduced. Would the human immune system suffer ... (more) |

How extensive could a habitable twilight zone be on a tidally locked planet? If a planet always faces the same side to the sun, so that it has a permanent night side and a permanent day side, it will have a twilight zone in between the two sides. This will be a band around the planet which permanently has conditions similar to dusk/dawn. If the day side is too hot and the nig... (more) |

Ensuring consistency in a world I want to be able to apply tools or methodologies to help ensure consistency in my world. For example: Burning world Imagine a planet with a land mass around the equator on which a great fire rages East to West at a rate allowing for regrowth by the time it gets back to it's starting point, so that...
