I am building a setting that is essentially steampunk,being exact it would be pneumatic punk. What electronics and electronic equivalent exists, are primitive and extremely expensive. Thus the majo...
We are using a Morris-Throne Wormhole Metric. Let's presume the throat of this wormhole (in internal hyperspace) is short, let's say 1km. Now, as you are travelling through the entrance wormhole,...
I was just bitten by a radioactive stopwatch, gaining the voluntary ability to experience time at twice the usual rate. While doing so, for every second of real time, two seconds occur within my bo...
A little snippet from my story idea, for some context- "The Earth Government Collapses, caused by the cutoff of resources from the Colonies. Large-Scale war soon erupts, with Nuclear Weapons being...
(or some other Lesser Canyon) I'm playing with story ideas for a videogame that takes place in the post-post-apocalyptic US. Everything is overrun with monsters and ocean horrors and whatnot, you'...
From my prior research I understand that there are several ways to remove or destroy proximal (subcutaneous) fat cells: Liposuction (primarily removal) Cryolipolysis (primarily destruction by f...
I wonder if it is possible to install artificial equipment that would exhaust oxygen into air in otherwise CO2 atmosphere so that locally people could breath in open air without any kind of tent or...
So given an Earth in our near future, year 2100 or so, where some of our tech has improved to the point where we have robots and the usual sci-fi devices for interfacing with computers. A colony i...
Oh yes, it's Artifact Time! with Best Dad and Ozen the Immovable! If you watched Hairy Plotter and the Gas Chamber of Secrets, you probably remember the scene where the Horcrux of Adolf Hitler is ...
Many animals have the ability to see polarized light (or rather, are sensitive to the direction of polarization), most notably birds and bees but also a wide range of other animals including cephal...
Assuming the axial tilt of the Earth was increased to roughly 30°, and the orbital eccentricity roughly doubled(0.03 as opposed to 0.016) so that the average temperature stayed the same, but the s...
I have a number of alien species from different planets with gravity between 0.5g and 1.75g and I wanted to have groups of each of the species to exist together in a space habitat. As pointed out t...
In an alien world, due to changes in the ecosystem animals that were once mostly arboreal started having to spend more time in open plains, adapting to fill a new niche of grasslands/bush eaters an...
I'm writing a short story where a group of explorers found a mysterious cave in a remote jungle , Inside the cave they find strange paintings of spirals resembling portals , after exiting the myste...
I have an idea for a land based mobile organism that moves and uses photosynthesis for its primary means of energy generation. Can a motile organism conceivably get enough energy from photosyntheti...
Let's say you have a planet about the size of Earth. It has three moons, each roughly the mass of one-third of the Earth's moon. Would this cause tides of different magnitude than those on Earth? A...
This is a submission for the Anatomically Correct Series Giant seahorses are often portrayed in fiction as being ridden by merfolk or other underwater people. I'm wondering if such a creature ...
There is a video from "What If" that tells about (precisely) "What if Earth was a moon of Jupiter":What if the Earth Was a Moon of Jupiter And, in a short story I am writing in an alternate realit...
The shell variant of a Dyson sphere consists of an artificially-made shell of material about 1 AU in radius encircling a star. The sphere captures most of the star's energy and stores it for future...
So, Georgie, the paladin who's still unsure about going down the path of lawful stupid, decided not to kill the dragon. Now, this means they can finally use The Orb of Dragonkind for something afte...
I did a lot of research and asking questions about dragons' breathing ability: if there was a dragon that spits pyrophoric liquids like a spitting cobra A tiny fire-breather can any animals (exam...
Skippable Introduction I asked a similar question 2 years ago and never got a real answer. I was told the question was too broad or "it can be whatever you want" "magic can do anything" so I thoug...
When writing a futuristic story I always try to minimise the impact of computerization. Its rather uncomfortable writig a story when technology is advanced enough that humans arent in a position to...
you know a jaw or mouth where the jaw full of teeth fully rotate like a drill or gear to shred their food or prey, usually show often in worm type of monster (my question is not necessary to be wor...
Death, most if not all of us fear it. However, it may be possible to postpone death for a while, and hopefully entirely. One major way of postponing death for awhile is through the biological route...
This is the world's tallest tree--the coast redwood. It can grow as high up as 115.5 meters. Any taller, and the transportation of water in its vascular tissues would not climb all the way. Bu...
Is it possible, given a strong enough magnet, to rip out iron based molecules out of the blood stream/body of a person/animal? Would such an event be the thing that kills someone or are there other...
So, when it comes to humanoid races, this has been a problem for me for quite some time. Sure, mammals (werewolves, gnolls, minotaurs, centaurs) are a no-brainer. I even decided to give tengu somet...
If we could replace DNA, RNA and the ribosomes in our cells by their mirror image versions, then everything would work in the same way, except that the chirality of all molecules would have been in...
Double or binary planets are a really cool science fiction idea. A second Earth hanging ominously in the sky. Co-orbital or trojan planets are also interesting in that you have them on more or less...
In the large pillar forests of planet x, a group of vertebrates, in order to hunt down the fast climbing creatures that inhabit their habitat, rather than developing speed as well, went on another ...
I came to SE WB while I was researching about space radiators for my sci-fi. I don't remember where exactly I found an answer to my question (Maybe? Idr) but I stunned with this site. You all looks...
I have settings with orbital colonies around the earth. First off my idea is, if it is not profitable we would not fund it en masse. Therefore I came up with the idea that in the future we discover...
Would it be possible for aliens that originated and evolved in a planetary system beyond the ring singularity of a rotating black hole to send individuals out into a normal universe to colonise it?...
I have this creatures which were hiding underground for millennia. They are, from the beginning of their history, exclusively nocturnal. They emerged back on surface after moon disappeared (irrel...
I want to know what kind of toilet design for mermaid is, considering they live surrounded by water and they poop through the anus (or whatever the organs name is) that located in the front rather ...
With the emergence of cyanobacteria on earth 3.5 billion years ago, the shift from a reducing to an oxidizing atmosphere began. "The atmospheric O$_\textrm{2}$ levels (in PAL; i.e., normalized to ...
Given that you can travel back in time and have a baby there, or alternatively, send your baby back in time, would it be possible that this baby one day becomes your own mother (gives birth to you)...
My friend and I are working on this world called Roia. It shares many terrestrial properties with the real life earth: composition, axial tilt, distance from the star, presence of water, etc. You c...
In this universe, Earth had a couple orbital rings during the construction of the colony ships that were sent to Alpha Centauri. Humanity has achieved fusion power and efficient space flight (1g ac...
I have been toying the idea of fusing our white blood cells which search and destroy malicious foreign bodies with artificial intelligence to fight various disease causing pathogens, my worry is th...
I'm not sure if this site or Astronomy would be better, but I figured I would try here instead. I am attempting to create a [semi]plausible star system in Alpha Centauri for a series. The system w...
Okay so i have this world that is inhabited by an alien race that outwardly is basically undistinguishable from an ordinary earth-human. Due to the specifics of this planet they live on they can br...
Under normal circumstances, monolithic diamond is pretty terrible at resisting impact, due to it being weak in certain planes, also known as cleavage planes. To solve this, why don't we just make ...
You are Alien McGee. For some reason ( don't ask why ) you need to hide an artifact in our solar system for roughly 20,000 years before coming back and taking it. Said artifact is a magical vase ...
Say humans found a way to exponentially increase the capability of plants to grow. Is it possible for it to cause an environment that can cause oxygen toxicity in humans?
Gargoyles are bipedal, slow-moving animals that lurk on rooftops and eat pigeons. The rumors of gargoyles being magical construct are false; in truth they're just animals that have adapted to urban...
I have a mental image of a humanoid species with hands possessing three fingers and two thumbs, on opposite sides of the hand: *note: it could be animalistic or reptilian, it doesn't need to be ...
Are there any areas of space where an antimatter object, the size of a small house could survive without coming into contact with any or extremely minimal amounts of matter? I had assumed in all a...
I think that robots in the future will have to have a system similar to adipose tissue that would have similar functions of those of people and animals. I believe that if an android is supposed to ...
