[Question] [ I've been creating a science fantasy conworld, but I'm honestly not interested as much in pre-industrial stuff. But I don't want to ignore the pre-industrial history, so I'm looking for a way for the Industrial Revolution to happen as soon as possible. While most fantasy settings are medieval, this one i...
[Question] [ There is a system of one star and something like an asteroid belt around it. But the distance between asteroids is much less than usual, with some perhaps within nine kilometers of each other, and sometimes even less (there can be closer proximity, to several meters, and collisions are very frequent). Al...
[Question] [ In the world I have been working on my planet has a gelatinous mass of cells coexisting but not a technical single creature. It bridges the gap between single celled and complex and it grows in size as it consumes organic matter (any organic matter). It divides in two like a bacteria when it reaches a la...
[Question] [ This planet is a rogue planet without any star or without being volcanically active. Antimatter continually collides with the planet, and annihilates with hydrogen in the upper atmosphere. This provides heat and light for the planet. Alternatively, the planet could be made out of antimatter, with regular...
[Question] [ **Low energy, fantastic range** From HDE in [another topic](https://worldbuilding.stackexchange.com/questions/63251/seeing-using-gravitational-waves), I learned gravitational waves have an intensity which is inverse proportional to distance, not square distance, like in electromagnetic fields.. $$h\sim\f...
[Question] [ I am raising dragons for my world. So far they had 4 limbs (2 legs that are also used as wings and 2 legs used for walking and grabbing things). But I started wanting to embrace the fantasy even more and now I've decided that they will have 6 limbs, 4 used for walking and 2 used for flying. But a problem...
[Question] [ There are numerous other question on this site about "If oxygen production stopped...?" but all of them appear to still have humans around. This question is different. In my scenario, we may assume that every single living thing on earth has been exterminated instantly. There is absolutely nothing left a...
[Question] [ On a distant world, the atmosphere is different than ours - there is no oxygen but a high level of C02 like on Mars or the early Earth. This planet is otherwise similar to Earth but slightly warmer. The planet orbits a Red Giant as a sun. The soil is rocky, and high in Silicon. If I want plants (photosyn...
[Question] [ I understand how complicated constructed languages can be. I do not want that though. The language would need no grammar or syntax. But I would like to create places/people names and maybe the odd noun for the language. But here's the kicker... I want to be able to generate these languages and quickly, o...
[Question] [ **Body:** Boron-based lifeforms that use ammonia as a solvent and respires methane & hydrogen, with an atmosphere of mostly methane, hydrogen, nitrogen and in smaller percentages, acetylene & other elements. The temperature of the lifeforms' planet is -10 Celsius, with the pressure being 25 atmospheres. ...
[Question] [ So, mechanical computers are a thing, as are pneumatic and hydraulic actuators. Combining those ideas, it's not that hard to design simple purely-pneumatic/hydraulic robots--provide them with a source of compressed fluid, and they just go (and that includes performing middling-complex mechanical calculat...
[Question] [ 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 isopropyl alcohol on a relatively warm planet with very thin CO2 atmosphere and less than half earth's gravit...
[Question] [ A spin-gravity space station, a ring-shaped structure that creates a faux gravity on the inside of the ring via inertia, has been depicted as no bigger than a house and as massive as a solar system. However, I expect there's some real-world limitations on size. With the understanding that any given ring...
[Question] [ If your ship just got trapped inside the event horizon of an super massive black hole, could the ship "accelerate" back out with an alcubierre drive? [Answer] Possibly, though you’d be escaping by moving the exit, potentially with hideously unintended side effects. Basically below the event horizon of...
[Question] [ I've read super-earths might become archipelago planets. Picture shallow seas, under a thick atmosphere that alternates between muggy and clammy. Because a bigger share of the surface would be continental shelf, there would be more room for kelp forests and other habitats propicious to photosynthesizers,...
[Question] [ Hundreds of years ago during the black plague, an individual named Howard Phillips Lovecraft started what would lead to the doom of humanity. Although a mediocre writer himself, his works of literature would inspire authors for generations. His most famous work, "The Call of Cthulu", was the first entry ...
[Question] [ I'm picturing a world without oceans. I'm not after Arrakis; I want a quite lush surface. I'd like no surface water at all, but I'm concerned that makes evolution impossible. (I imagined using chemotrophs to get around it.) I want a "sea level" pressure of 2-6x Earth. If there's surface water, it'd be "a...

[Question] [ I'm working on a story set in an Earth-like world but with rings (say, proportionately similar to Saturn's). I'm trying to get a solid handle on how these rings would affect the sky. For the purposes of this post, let's focus on *navigation*. For a little more info, let's assume a location in the Norther...
[Question] [ I'm basically looking for advice on how to balance the magic system I'm designing for my novel. Basically, the way it works is this: There are six known Realms beyond this one where almost magic users draw their abilities from. Such a magician is called a Realmtapper. Each Realm is tapped into a bit dif...
[Question] [ One of the worlds I'm creating has a planet-wide communal sentient Biosphere (similar to *Avatar*). They have evolved the ability to bio-engineer whatever they need, and they have decided to send a probe into space for exploration. I've "borrowed" Larry Niven's Stage Tree concept, using Ethanol and Pinen...
[Question] [ What advantages would extreme longevity need to provide for it to develop in a human subspecies/humanoid species without outside tampering? I ask because elves and the like in fantasy are often depicted as living far longer than humans do, and are healthier for longer into old age, and assuming that's no...
[Question] [ In what I hope to be the first episode of a series, I'm going to highlight each piece of Tolkien architecture and see whether or not it's practical enough to use in real life, starting with the simplest: Orthanc, the centerpiece of Isengard.

[Question] [ I've become interested in different kinds of dinosaurs lately, and have also been on a creature design kick. Let's talk about [Troodons](https://en.m.wikipedia.org/wiki/Troodontidae). Troodons were a type of theropod dinosaur with unusually large brains and excellent senses. Some people have thought that...
[Question] [ Aliens build their city on Earth in such a way that it covers the entire planet but leaves the surface of the planet (including human cities) intact. This is possible since they built their alien city on a huge platform which is supported by pillars rammed into the Earth's crust. So with exception of th...
[Question] [ My first post, I am sure I will have many more! I am so excited to have found this community! I have a game called Rise: The Vieneo Province and a very old issue that I was hoping to get help with. According to our [wiki](http://rise.unistellar.com/Vieneo) for our fictitious planet, the surface pressure ...
[Question] [ How would a medieval doctor identify a poison that was administered through a cut? Is it strictly by symptoms? If the implement is produced, would that help in identifying the poison? The story is fantasy, but I've tried to stick closely with historical and medical facts from medieval times--14th to 15t...
[Question] [ I am writing a story that takes place in a big desert. I've figured that I could make my desert as extensive as possible by building a Pangea-like supercontinent, since I've learned here that, given the distance, eventually the clouds from the surrounding seas will exhaust their water. However, I want to...
[Question] [ There seem to be honest scientific exploration in the field of the alcubierre warp drive if you believe some articles on the net. So to be a little bit scientific accurate in a story using it, I wonder about the following: The warp drive deflates space in front and inflates it to the back of the ship, th...
[Question] [ I am often fascinated by one of Earth's most magnificent beings, the mantis shrimp (also known as 1-2-3-death). These beautiful animals have sixteen kinds of colour receptive cones - compare to our measly three! **They can also see polarized light in ways that we cannot.** Which got me thinking... What i...
[Question] [ I have a binary system in which my world orbits one of the stars, not the pair, in the habitable zone.

[Question] [ I'm currently building a world for a medieval based D&D campaign (i know super original) and I'm trying to make my cities as realistic as i can. Right now I'm planning on making a city in the middle of a large empire with roughly 100.000 people living there. But now comes the question of how big would th...
[Question] [ It's become a popular speculative evolution trope for the likeliest candidate of the mythological "wyvern" to be a Cenozoic family--if not **super**family--of scansoriopterygid dinosaur. Now the first thing you'd be wondering is, "scanso-WHAT?" and I won't blame you. The name is not as memorable or catch...
[Question] [ The year is 2100. While climate change has wrought serious damage to the biosphere, humanity has at last managed to become carbon neutral, and has even developed technology that can be used to reduce the level of carbon in the atmosphere. This has the effect of allowing humanity to set the thermostat, as...
[Question] [ In a world where every human mind has been uploaded, and no organic humans remain, can we still produce offspring? In a worldbuilding project I'm dabbling with, there are many people uploading their minds to a virtual world. I ran upon a roadblock, though. Could the people in the virtual world, who don't...
[Question] [ Could a species with an incredibly advanced electroreceptive organ (such as that of a shark) be able to use it above water? The gas-mix in which the sense works must be breathable to humans, and it would be good if it was the same mix as in the earth's atmosphere. [Answer] TL;DR: no. --- Electrorecep...
