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 civilisati...
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...
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 lan...
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 m...
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 di...
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...
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 planet...
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 fou...
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),...
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 t...
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 ...
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 fir...
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 hav...
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 o...
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 aft...
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 considerin...
