This question has two parts: Could biological processes create an organism than can see in wavelengths outside the human-visible spectrum? ("Outside" meaning some significant amount outside. Ther...
I need an advice about creating an independent city (a city state) in the middle of a desert (the stony kind of wasteland). I will scratch what I have in my mind so far and I would be glad to hear ...
Let's say there's an OCEAN planet smaller than Earth but larger than the Moon. The Sun lights on the ocean planet reflecting the water textures onto Earth. Would it be possible to see watery refle...
What would a human colony on the moon look like? I already asked a prelusive question here about the safest place to start a moon colony but I needed further informations. After some answers, I re...
When the skies release a column of fire, the land around becomes a barren place... Can such phenomenon be explained with some rare, but "closely possible" circumstances? I don't think about ...
I'm working on a universe which implies that humanity settled on the Moon. Knowing that we want to keep contact with the Earth (means we don't want to settle on the hidden face) and we want to avo...
In this hypothetical world, evolution occurs as it should. (Not to run afoul of any genetic diversity requirements of evolution; some simple viruses have aided in the genetic shifting process). But...
There is a cold planet (maybe a moon of a gas giant) far out in a solar system. It has a solid core and the surface is a thick layer of ice. Because of nuclear fission in the planet's core it is w...
How would human culture and civilisation develop if placed onto a planet permanently psychoactive, e.g. because of low (but inevitable) amount of LSD-like substance in either water or air? To simpl...
I am wondering how possible (and also, how it might work) something like nanobots would be. The technology level definitely would be higher than it is currently, to the point of pocket universe tec...
Suppose that Khufu, pharaoh of Egypt and builder of the Great Pyramid of Giza, was introduced to the idea of an amusement park. More specifically, suppose that he was visited by a time traveler a...
So, I understand that human skin color is based on the distance from the equator, but would it be possible to evolve skin to be a non-natural color such as green, pink, blue, purple, ect? Perhaps i...
By some combination of changes in both the environment, and human biology, humans evolved on Earth in a way that basically makes them 100% unable to alter their minds using traditional methods: A...
A rare opportunity to send a colony ship off-Earth arose. The target is a somewhat Earth-like planet, with the exception that it was apparently conceived by George Lucas, as it only has one climat...
Are there any valuable deposits (gold ore, iron ore, silver, copper, gemstones) which are likely to be found in or around excavation sites for building materials like limestone, sandstone, slate or...
Here's the set up. In my slightly-futuristic mildly-sci-fi novel, I have a need for an aerial transport vehicle (I have been informed what I need is closer to a VTOl than a hovercraft). These craft...
This is in my world of balloons and zeppelins, war and peace, day and night. Sleeping may be the least important thing but it is still important. On this world, the day and night cycle is 8.89 of t...
The basis of almost every food chain in existence relies on plants in one form or another, but let's the sun couldn't provide the earth with enough energy for plants to exist. What can possibly rep...
In my world, daytime lasts for 9 years. I am trying to make this as realistic as possible. How would life live on this planet? How would they sleep etc.? My own theories are that they would mig...
If we had Full-Body Immersion MMORPGs, how would morale-boosting and morale-lowering skills work for players? By that, I mean, how would the game forcibly make players more or less confident, even ...
In my world, Earth populated the Moon. Even if people are concealed in stations they got to go out from time to time (to explore or repair things that robot can't). My question is: Is it possible...
In this world you have access to computers powerful enough to decipher messages as long as the method used to encrypt it has at least one theoretical weakness (those computers cannot defeat an impr...
In a world where there are strict controls on "computational and instruction following machines" (all calculation machinery are basically none reprogrammable and limited to specific narrow tasks - ...
This question is intended as a follow up to this one: Naturally occurring wheels - do the 'mech' vs. 'tank' comparison apply to organics? I agree with the arguments against wheels evolving in plac...
The planet in question is this one. Approximately three quarters the size and half the gravity of Earth, an atmosphere 25% as dense as the Terran one which mainly consists of Nitrogen with small pe...
