How would a Universal Coordinate system work? We have a variety of ways of describing our location here on Earth. We can refer to a nearby landmark (eg "by the City Hall"), we can describe our location relative to an area (eg "in the South of the island") and we can describe our location with Longitude and Latitude. It is the later of these me... (more) |

How to make vehicular combat viable in a Post Apocalyptic world? I want to create a Mad-Max-esque post apocalyptic setting. Unfortunately after a bit of looking into this, there is one massive issue with the idea of lots of maniacs tearing across the barren landscape of a post WW3 world in their armoured cars and trucks: Fuel. The fuel of all of these cars and ... (more) |

What would the weather be like after the world is shaded by an immense object? I have a situation in my imaginary setting, and I am specifically interested in how this situation would affect the weather. The situation is as follows: Positioned above a large landmass of my world is an immense flat disc, at least two thousand miles in diameter. It is thin and has compara... (more) |

How would the weather act if you blocked sunlight? Consider a large flat disc, at least two thousand miles in diameter. It is thin and has comparatively little weight or mass, but it is also opaque and does not let any light through. This flat disc is positioned roughly 40-50 miles away from the surface of our planet, and the disc is consistently h... (more) |

How close to the Sun would you have to be to hear it? Taken from this fascinating answer: The Sun is immensely loud. The surface generates thousands to tens of thousands of watts of sound power for every square meter. That's something like 10x to 100x the power flux through the speakers at a rock concert, or out the front of a police siren. Ex... (more) |

How long until two planets become one? Two Earth-like planets collide at a (relatively slow) speed of about 1,000 kph. For all questions regarding the size and composition of these planets, just think about Earth - and these two planets are moving towards each other at the same speed. 1) First, they would begin to rip each other apart d...

Life on Smooth World Welcome to Smooth World. Most of this planet (at least two thirds, but preferably more) has only tiny differences in elevation, 30-40cm at most. No hills, no mountains, no valleys. Even plains found on Earth usually have a fair amount of difference in elevation, but not Smooth World. From a far enou... (more) |

How big can a carbon nanotube structure get? I am making a "structure" out of carbon nanotubes in deep space. This structure can be any shape or design, I just want it big. Big in just one direction is cheating (so no long thin structures), this has to be big in all three dimensions. Approximately how big can I make this structure before its... (more) |

Hiding a Gas Giant I have a habitable Earth-like moon that orbits a gas giant. This moon is inhabited by a pre-medieval civilisation that has spread out across just one continent. The inhabitants of this civilisation are unaware that the moon they are on is orbiting a gas giant. I am guessing this is possible becaus... (more) |

Are there any real world examples of where a desert and a swamp meet each other? I am building a world with many deserts and swamps. So a simple question: Are there any real world examples of where a desert and a swamp meet each other? Deserts and swamps are vastly different types of terrain (one containing hardly any water and the other containing lots of water), so I would as... (more) |

Fireproof Plants Is it possible to have plants that wouldn't burn? Having the plant getting damaged by fire is fine, but I want the plant not to burn at all. It does not need to survive, it just must not catch fire (for roughly an hour). This is going to be a plant from another world, but I would like to know if th... (more) |

Building a Base on the surface of a planet like Venus I know living on Venus would be virtually impossible for us now. But I'm trying to picture what life would be like on the surface of such a world, and how advanced in technology a species would have to be in order to achieve it. Whatever species is on Venus obviously didn't originate there, so this ... (more) |

Conditions needed for a Fractured Moon After seeing the film Oblivion I began wondering about what would happen if the Moon was fractured in such a way that large chunks of the Moon were ripped apart. Would the chunks of Moon stay in orbit around the Earth, or would they drift off into space? The film shows that the majority of them flo... (more) |

Precious Materials in a Galactic Empire Picture the future, where man kind has spread out across the galaxy. What would be the most precious and sought after materials? Today it is metals like gold and platinum that are most sought after. Would this still be true in the future? Am I right in thinking gold would be more abundant in space ... (more) |

Travelling through space around Worlds inside Nebulas I am building a habitable, Earth like planet, but instead of it being in a solar system, it is inside a Nebula. The actual composition of the Nebula is uncertain at this point, but I am considering something like the Orion Nebula. Imagine if there was a vast cloud of gases, similar in composition t... (more) |

What would skies look like on Worlds inside Nebulae? I am building a habitable Earth like planet, but instead of it being in a solar system it is inside a Nebula. The actual composition of the Nebula is uncertain at this point. I am thinking the planet still needs one or more stars (that are also in a nebula) to provide it with light and energy. I a...

The opposite to Worldbuilding: World Destruction I am looking at different ways to destroy a planet. I am assuming the planet is of a similar size and composition to the Earth just to keep things simple. I am starting at boiling the atmosphere to the point where it turns Earth into a dead barren rock with no vegetation, no oceans and no air left. ... (more) |
