I'm designing a world similar to Earth (liquid water, temperate climate, there is an atmosphere, oxygen and complex life everywhere). The only big difference is that there is a giant (not glowing!...
I'd like to have an advanced civilization that lives in a ring around their sun, but a ring planet just can't work. In this case, they are among densely agglomerated asteroids (with life support, ...
I've posted a previous question similar to this in the way that it is of my WIP web-comic. The planet my friend and I have designed is strange as she wanted to create either a permanently dark plan...
I'm working on a setting for an RPG, and I'm trying to build my planet so it's unique and interesting, but also semi-plausible. My question is, could you have a planet in stable orbit around a mag...
I am making a sci-fi web-comic set on an alien world and I thought up an idea for an eye that works much like an eye from a mammal, but instead of moving the whole eye, only the pupil moves. This i...
In a non-magical world where homo sapiens has evolved into several races or breeds (like dogs) or even species as in Q10102 and Q12190, that can interbreed for the most part, how can one model the ...
I trust Brandon Sanderson to have done his research - in his book "The Rithmatist" he writes about coiled spring batteries that power a passenger train. I do wonder what could be achieved with a sp...
In a setting I've been working with, I sought a method of sublight travel that wasn't crazy engines or magic. I've already got FTL using a different method than the Alcubierre drive, so it wouldn't...
Magneto is way over-powered, even for a mutant. With the given relation between electricity and magnetism, what could be possible? here is already study work on biomagnetism, we know the nervous s...
Buildings are often build on the ground into the sky. Would it be conceivable if instead, we build down into the ground instead? We wouldn't have to worry about wind then. I think we could go farth...
Are there models, problems, and or engines for building life-sustaining worlds? I believe that my approach is backwards. I have written a lot on my world and have been slowly working at making th...
Back home, the phylum Cnidaria (jellyfish, coral, anemone) and the class Amphibia are two of the most ancient groups of animals on the planet. But let's say that, on an alternate Earth, many milli...
Many questions on Worldbuilding have posited different reproductive strategies that often result in the virtual enslavement of females (when there are females involved). On Earth, normal human biol...
This question has no background information here. I just want to know if there are any evolutionary advantages for a species to have 4 ears?(The kind a mammal has).
For this question lets take a trip to Slyo Dacas: Slyo Dacas (sil-yo-dak-iss) is a world roughly the same size of Earth with a decent magnetic field and no moons. The world is a bit drier than...
So having read a couple of other questions on here, and postulating over this for a while, here's my question. Is it possible to have two magnetars in a distant binary orbit, with an earthlike pla...
Set in year 2615 A.D. humans have colonized nearby star systems, we can travel between different star systems using artificial wormholes. A spaceship leaving Solar system for Alpha Centauri have to...
Let's make the following assumptions: Artificial Superintelligence (ASI) is inevitable, much like Y2K was. People assumed that this ASI would have the power to prevent any other ASI from being cr...
I'm currently writing a military science fiction story set in a post cyberpunk world I've been building. The story focuses on a tank crew, but it also prominently features an enormous airship that ...
I am working on an alien species with mammal-like features and characterized by radial symmetry, in opposition to bilateral. They have four lower limbs arranged in a square-like disposition, with t...
Here is another planet question for you planet enthusiasts. I have this planet... It's called Barahecio. The Mars-sized sphere's average temperatures hover near the freezing point of water. Of n...
It's well established that the human body does not do well in zero gravity. Symptoms such as fluid loss, muscle atrophy, bone mass loss are well known. Less well known problems extend to such mun...
Okay, I will make a little premise/context to give the question a decent background. I know that the scenario could look rather "handwavy", but take it as the framework on which the answer should b...
Mycolaria is my working name for an alien planet featuring a much more visible role for fungi of all kinds, large and small. There are also animals and plants on this world. This is the second in a...
Imagine a planet whose surface is perfectly spherical, without any kind of obstacles anywhere. In such a world, it would be a competitive advantage for any lifeform to evolve wheels, as transport a...
