I'm new here but I've been a worldbuilder for the last decade or so. I'm pretty late to the 'mapping out your country' party and I've only been at it for about 8 months, but I'm starting to see som...
According to Natural nuclear explosions natural nuclear fission reactors could occur. Could it happen that a primitive alien civilization has its social, economical and technology evolution trigg...
I'm writing a story in which a civilization previously capable of (firmly technobabble-based) FTL travel has become stranded, orbiting an isolated star with no rocky planets. (There was a planet, b...
Inspired by this question, what would the pressure stabilize at over tens of thousands of years (at the moon's centre, surface, and any other interesting points) if you created a structurally stabl...
Is it possible for an artificial satellite (in this case, an unmanned communications platform) to maintain a stable orbit directly around the barycenter of a Binary Star system, as in well inside t...
I have a scenario where a spaceship has been badly damaged and now the normal vibrations of the power supply are becoming amplified through the damaged hull, and threatening to tear the ship apart....
Suppose a universe with similar physical laws to ours, with the major exception of gravity not existing as we know it, with an analogous force (hereafter called gravity for simplicity) acting as a ...
I have an idea that the seas of a world are red, not blue. However, the world should also be the birthplace of an intelligent alien species. Would it be scientifically possible to have a world with...
Okay, so how feasible is it- if even possible- to put the Earth under 'one roof'? So here is the premise. The world is heavily heavily over populated, so overpopulated in fact that almost all of t...
Let's say that suddenly NASA needs my characters, a party of scientists without prior experience, to go to space with a Space Shuttle-like spacecraft for a seven days mission. They only need to do...
A solar eclipse occurs when the moon passes between the Earth and the sun. The result is a giant shadow that sweeps across the Earth's surface. This world has the opposite phenomenon. Instead of a...
How would a mechanism look that allows a person to e.g. turn a crown-sized wheel (from a watch) by any amount (e.g. 180 degrees) resulting in a turntable (from train yards) turning the same amount ...
Could a ~150 mile (240 kilometers) crater form from a small object impact? So the object impacting the site of the crater is a human shape and not able to be destroyed. The location of the impact ...
I've been thinking of a planet where the day/night cycle is way off to where there 30-35 hour long night period, while there are only near 8-4 hours of daylight. The local biological environment is...
So I have a race of shapeshifters in my world, and in order to change shape or make adjustments to their body (grow wings, arms, tails etc.) They rearrange the atoms in their body, probably through...
Setup: A planet generally with an earthlike climate, although slightly wetter and warmer as a general rule, with a little more oxygen in the atmosphere, but habitable by unmodified humans. Still h...
I'm no engineer, but I was wondering how a steam-powered door would work. I want it to be difficult to open unless you know how (not a simple "twist the doorknob and open"). There is access to plen...
Recently, pictures taken by the New Horizons space probe were released depicting the unusually-shaped object Ultima Thule. Now, suppose there was an world the size of the Earth, but in the shape o...
How many rocket launches are needed to change the axial tilt of the Earth so much that it is noticeable with instruments available today? We can assume that we are talking about the heaviest rocke...
An alternate world is populated by mainly intelligent trees and other plants. These plants are almost exactly the same, biologically, as Earth's plants. The world's climate and geology are very sim...
I apologize if this question is not written up to standards, I am rather new to this site. I have been an avid fan of chucklefish's acclaimed sandbox title, Starbound, for a number of years now a...
Worldbuilding and biology have always been two huge passions of mine, especially when it comes to dragons. So well, at the moment I'm working on a little project in which I'm attempting to make dif...
before I get into my question I wanted to thank everyone for their input in my first thread about the general principles of river drawing. I have taken your comments under consideration and began r...
I've already considered that they may file their horns down, but keeping in mind that their horns gradually regrow, it is an inconvenient solution. This is what their horns typically look like: ...
With the Kuiper Belt being composed of well over 100 million objects - some grand, some insignificant - is it possible to hide an asteroid base from enemy sensors within its confines, combined with...
