Assuming that some future civilization of hyper-advanced humans, or aliens for that matter, had the technology to reshape the solar system so that there were several habitable planets the rough siz...
Bryan Konietzko (you know, one of the guys being Avatar The Last Airbender and The Legend of Korra), is working on a new project called Threadworlds, which takes place in a solar system that has 5 ...
My fantasy world consists of a flat plane, with the sun affixed to a point directly over the main continent. This sun powers down to create night conditions, and then powers up again in the morning...
BACKGROUND So I was working on a map, when I suddenly realized that despite the many helpful tutorials on this site I have very little idea what I'm doing. I thought it might be a good idea to put...
In my world, there is a chain of offshore volcanoes which are the result of a smaller plate hitting a larger one. There are two to three active volcanoes. My question is: two of these volcanoes a...
This question assumes that there is complex, intelligent life on some other world other than the kind found on Earth. Carl Sagan allowed that silicon and germanium might replace carbon, and ammon...
As the title says. I need to have at least 3-5 habitable Earth-gravity worlds (preferably with atmosphere, nitrogen oxygen) as many smaller, lifeless moons as possible, and a planetary ring. (i.e. ...
What biochemical reactions might be employed by plants to harvest heat energy when light energy is scarce or even missing? What is the temperature range over which this biochemical reaction can wor...
(Please see diagrams) This is a question regarding an area of a Rocheworld scenario that I haven't found anything on. It is suggested that the OUT side of a planet that is tidally locked with an...
Even disregarding the blatantly supernatural examples of demons and the like, some humanoid races in fantasy are depicted as having horns, or at least something similar to that, like bony protrusio...
My winged people just have feathers on their wings, and maybe small feathers on their back between their wings (from shoulder blades to mid back). Their bodies look generally human. Here is a lin...
This probably sounds fairly ridiculous- I know, but in short I've been developing a sort of future earth. It's not extraordinarily accurate, but I've been trying to at least keep the obvious in che...
In the science fiction setting I'm working on, I had a thought on how to reduce the detection ranges in space. On a previous question, I suggested the idea of capital ships and other support ships ...
Let's say I'm a secretive organization who's recently come into possession of two individuals of the genus, Giraffatitan (a sauropod similar to the more famous Brachiosaurus for those unfamiliar wi...
I am working on a fictional story, but I want to have a few accurate scientifically accurate (or as close as possible) situations. Question one is: if a person falling at full terminal velocity, o...
Dragons are often thought to have impenetrable scales. If dragons were to shed them it would obviously make them far more vulnerable for a period of time. This on the other hand would make them eas...
What would cause a short fantasy race, like dwarves, hobbits and/or goblins, to maintain their smaller size outside of the environment that produced it? I know that the exact height of these races ...
Inspired by this question: Sexual reproduction without biological sex And, to a lesser extent, this question: Would a society of simultaneous hermaphrodites have gender roles? I'm not particularl...
In a Rocheworld scenario where two planets are tidally locked and share an atmosphere, but where both the planets are so small that their gravity is very little (as low as one of the dwarf planets ...
(Warning: do not try this at home-system) Preamble Hello humans, we need advice. Let's say we have just successfully defeated and killed a Horror From Beyond Reason who happened to be multiple t...
Obviously, you can't just send a bunch of out-of-work Kentucky coal miners up there to give it a go. You need some sort of specialized equipment. What I want to know is: what equipment will it be? ...
This question is pretty straightforward. I would like to build an earth-like world in which humans don't have access to iron, or at least can't mine any prior to full scale industrialization. They ...
Let's say we have a micro-gravity environment where people are staying afloat in the air because they have wings or some other means of resisting the low gravity, but then for some reason they find...
You know what they say, the best offense is a good defense, and with the Energized Particle Shield 9000 (patent pending) you will have the ultimate defense possible! The EPS units can be scaled up ...
The Rankine cycle describes the ideal thermodynamic cycle for a heat engine to produce the best performance and convert heat into mechanical work while it undergoes phase change. Is it possible for...
