Where do producers get nutrients in an airborne ecology? So I'm designing a world where the air has its own ecosystem, separate from the one on the land, because sky whales are cool. However, I'm having trouble figuring out what the plants and other producers would use to, you know, produce. In the ocean, you have stuff like phytoplankton, which get nutri... (more) |

What makes a dragon's scale so tough? Many fantasy stories involve some variation of a dragon, and while there's a lot of variation in whether or not they fly, if they can breathe fire, how magical they are, etc., the strength of dragon scale is almost universal. Often, it is the hardiest material in the setting. My question is, by what ... (more) |

Planes in Saturn So I'm writing a story that takes place in Saturn's atmosphere, and I've run into a bit of a problem. You see, I wanted it to be possible to have some pretty badass scenes with sci-fi fighter jets taking place. (Yes, I know that real life fighter plane combat is a lot of hoping the targeting computer... (more) |

Would ablation be an effective way to redirect objects in space? So I'm writing a story set in the close(ish) future(say 2130), and space debris is starting to be a real problem. Stations in orbit are constantly having to maneuver out of the paths of orbital debris, at least a few satellites have been taken out, and it's just a big hassle all around. So (space or... (more) |

Gas Giant Station Design What would, roughly, a scientific research station look like on a gas giant? Use Saturn as a baseline. The station would float because of a "balloon" carrying nothing. Vacuum is the lifting "gas", as the atmosphere of most gas giants is already hydrogen/helium. The pressure at the average elevation ... (more) |

DIY Genehacking: What can I do with it? Assuming an average, fully developed adult man, what sort of changes could be made to his genome that would have a noticeable effect on his mind or body? To the best of our current scientific knowledge, that is. I know we don't know what a lot of genes are for. To be specific, I want to know if you... (more) |

Flying Bike: Steering Ok, so I'm making a setting where people have colonized various objects in the solar system and out of it. One thing I know I want to include to flesh it out a bit is a sport for low-gravity environments involving human-powered flight via lightweight machines similar to bikes. One of the things I'm h...

Metal foam for space constructs So I'm writing a setting featuring asteroid mining à la Deep Space Industries, where the material mined is used for construction in space rather than brought to Earth. To maximize efficiency, I'm thinking of the main material for construction being steel foam (foamed steel?), but I don't know how fe... (more) |

On feasibility of rotating space colonies Would a spoked, rotating torus work as a method of colonizing space? If so, how feasible would it be? As in, what would be the cost, where would we get the materials for it, how fast does it have to rotate to simulate earth gravity, etc. I'm actually thinking of a design somewhat like a wagon whe...

Effects of visiting other planets I'm wondering what adverse effects might be felt by someone from a planet with, say, 80% of Earth's gravity and a denser, but breathable, atmosphere with a higher concentration of oxygen visiting a planet with around 110% of Earth's gravity, and around the same atmospheric conditions as the Earth. T... (more) |

Could there be a planet bigger than Earth, but with less gravity? Is it possible to have a planet that is both bigger than Earth and weaker in terms of gravity? I've got an idea about it being less dense, but I don't know what to do about its magnetic field. I need to know this because I desperately want to write a short story involving human-powered flight with ar... (more) |

Air density for winged human flight? How dense would the atmosphere of a theoretical planet have it be, in relation to Earth's atmosphere, to fly with, say, a 10 to 15 foot wingspan? Math is acceptable and encouraged, and a set of artificial wings is assumed. I'm thinking an incredibly tough (fictional) plant fiber spread over a carbon ... (more) |

Vacuum instead of light gas? I know that with a vacuum, you'll be able to gain a whole lot more lift than with any gas. I'm just wondering how you'd do it. What would be needed to make a vacuum balloon as opposed to a hot-air balloon? (more) |

Wing suit plus gas vs parachute? Would it be practical to use a "squirrel suit" and sacs of buoyant gas for deceleration from a free fall as opposed to a parachute? Furthermore, once the sacs have been inflated, could the person in the suit gain altitude? In this world, flitting from platform to platform is a form of sport. (more) |

How could a large spherical plant heat air inside to fly? In another question, Are flying plants possible?, a point was raised that because of the square-cube law, a large, hollow, spherical plant could fly by having the air inside be a little bit hotter than the air outside. I'm wondering how a plant could heat the air inside of it up. Any ideas? (more) |
