Would it be possible to have an organism to be based on alcohol, rather than water? Complexity does not matter, but a complex organism would be favourable. their environment would be in oceans of i...
Imagine a Mark Wattney-like scenario, only on Titan and involving a decent-sized base being isolated instead of a single person. There is not, and never has been, the possibility of growing potatoe...
I want to know whether there is a way to make coins that are "swimmable" in the fashion of Scrooge McDuck. My inquiry is based off this Family Guy meme from Pinterest The coins don't necessari...
Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process & ejected backwards along its p...
Magnetic white dwarfs (MWD) comprise almost 2 % of all white dwarfs and they are characterized by having a strong magnetic field, whose strength varies between 1 T and 100 kT. Compared to the Earth...
So the Plasma Cannon proved to be a bust, now to the next weapon, what which is commonly associated with 'Exterminatus', the Atmospheric Incineration Torpedo. This bomb is far more powerful than a...
Suppose I want to have a moon with more gravity than ours how large of a moon can I have and what effects would there be.
Someone in the comment section of my previous question pointed out the energetic problem of ectotherms with human intelligence (the brain needs a lot of energy). I still want to keep my lizardfolk...
Summary at bottom. I have a character from a homemade alien species. The species has silver/white hair and blue/violet eyes. I know these are traits of a melanin deficiency, but I imagined her hav...
One thing I like about Attack on Titan are those lovely Omni-Directional Maneuver (ODM) gears! They're the perfect combination of a jetpack and a grappling hook. I love how the thrusters are placed...
First, a clarification: Dwarfism is the umbrella term for 200+ medical conditions that result in short stature. Since this is Worldbuilding, my question refers to human beings with genetic dwarfis...
So I've been thinking about the idea of a series that takes place on a small fleet of generation ships, traveling at around 10% of lightspeed to Proxima Centauri, which should take around half a ce...
I want a character to be able to spit/spray from the mouth many different liquids created within the body. Liquids would include a strong acid, flammable liquid, strong poison/nerve agent, a stick...
Following on from this question. Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process &...
Would anyone be able to check some math/ let me know if I'm thinking of this the correct way? I had an idea of the moon appearing basically stationary in the sky, but in fact it orbits just faster ...
A habitat/space harbor ring encircles an ice giant crossing both poles (polar orbit) and rotating to create artificial gravity. Can the ring also precess in synchronization with the planet's year,...
For space-based warfare, would an orbiting satellite which was equipped with a railgun cannon be effective against a ground-based fort, or even an aeroplane, or another type of air transport? This...
I'm getting into mapmaking, which I enjoy, but some of the specifics of realism still elude me. I know generally how plate tectonics work, but I was hoping to get some help on a specific example. I...
I'm working on creating a planet that is tidally locked to a red dwarf, which is in turn orbiting a main sequence star which is much further away. My idea is that the tidally locked side of the pla...
A runner has superpowered legs, allowing him to run extremely fast (as in, each of his legs can "push" the ground very fast.) However, he has two different options for how he should run. Should he ...
As the title: What organs or modifications would be needed to have creature that can eat/digest hair without problem? (Preferably digested normal/quick enough, and they only eat hair.) This inclu...
I know that red dwarf stars are dimmer than ours. But I also know that red dwarf stars emit a lot of infrared light, so creatures on a world orbiting it would have eyes that see infrared light. I...
The main source of free energy that allowed life on Earth to develop was our sun. It bombards the planet's surface with photons of high energy, which provide activation energy for reactions necessa...
Rivers of lava are a staple of fantasy. But in the real world, lava flows are usually very short-lived phenomenons caused by volcanic eruptions. Is there some plausible way on an otherwise earth-l...
In my fantasy setting, cyclopses are large (about the size of a rhinocerus), carnivorous humanoids. They have a single blunt horn on their forehead, which is their primary tool for taking down prey...
