I'm currently outlining my science fiction novel which deals with humanity reaching Type 3 civilization status. My goal is to place an emphasis on hard science fiction while featuring fantastic tec...
I don't like the direction where mankind is going. We spend more resources to build tools which allow us to watch cat videos than on curing cancer. One day I decided to say enough, and leave this ...
In one of the most empty regions of space between the galactic superclusters there is a giant space bubble, with a radius of about 1,000,000 light years. Most of this bubble is one molecule thick ...
The jackalope is a mythical animal of North American folklore described as a jackrabbit with an antelopes horns. It's a popular mythological creature in hill folk culture and it made me ask a quest...
I want to write a novel situated in a "reversed planet": there are two stars orbiting each other, and there is a little spot exactly in the middle of the two that is suitable for life. A normal pla...
[Edit: I'm not looking for 100% realism. I'm looking for an explanation as realistic as possible, possible with just few exceptions to physics.] [Edit 2: In my imagination these worlds are differe...
Your large spaceship is damaged beyond repair. You manage to get it close enough to a planet so that you can release emergency shuttle craft. You have very little control over the ship and won't be...
Panotti so called from the Greek words πᾶν and οὖς for "all ears", were a mythical race of people, described as possessing large ears that covered their entire bodies. In the Natural Hi...
Another question based off of this one here. Let's say on a cube styled Earth-like planet, there was a similar race to humans. If the differences in the planets were minimal (besides, you know, the...
I'm trying to write a story where the main characters discover the wreckage of a spaceship in the fields that border their town to the west. To the east, there's the end of a large mountain range. ...
I am making a reincarnation novel with all of the protagonist's memories intact from the previous life. So what is the time when the protagonist can actually communicate through speaking?
When the old mining town was founded, nobody did think of this ever growing into much more than a coal-mining town. The deposits of iron-ore, aside from the already developed peat bog to the nor...
I'm trying to work on a chapter in my lore but I'm stumped on how agricultural developments could work in tropical settings, and real world examples so far mostly include temperate places, I.e. Bri...
In the year 2071 the Dysnomia incident happened. The Dysnomia (a mining ship) suffered a catastrophic failure and violently exploded sending its payload, an aged comet, hurtling towards earth. The ...
On the planet Blob there is an unusual phenomenon. It is known to emanate from the planet's core but 2018-level scientists have no understanding of it. The phenomenon Gravity isn't constant. It v...
You have an underwater civilisation, be they merpeople, octopus people, partially evolved humans or not. One thing that is always considered as a necessity in the development of any society is mini...
I've done a fair bit of research to come up with this scenario. I hope it's not "too broad" to ask for a reality check. Have I overlooked anything? Does it all sound plausible? My world takes plac...
Objective: Replace the human digestion apparatus (stomach, guts etc) From my basic understanding the human body needs food, because it needs ATP (energy unit, some kind of sugar(?)) or you could s...
In post-apocalypse fiction, diabetics, if they are ever even mentioned, are typically portrayed as utterly, irrevocably screwed. In fact there was a pretty cynical example in Dies The Fire (a book ...
Wild boars are well known for their large, bulky body, their aggressivity and their tusks. They are animals from which a predator would gladly stay away if some easier prey is available. And, las...
The succubi are popularly represented as women with horns and bat-like wings. They feed on the vital energy in myths, but could a humanoid creature resembling a woman evolve and feed only on human ...
One major problem with living underground is you lose all of that wonderful energy provided by the sun. This energy is useful for many things including growing plants for food. A window is effectiv...
Looking to how I can make Nagas and Mermaids able to exist and evolve in my story, I came across this post which explains how Nagas could evolve from humans: Anatomically Correct Naga In the top a...
Long ago, I asked for a kind of steel alloy under an alternative recipe. Right now, the list is as follows: Carbon (2%) (Reasonable material and amount) Chromium (12%) (Reasonable material a...
We all at some point in our childhoods thought that the moon is made out of cheese. As such, I thought: under what circumstances can a planetary surface form in such a manner that it is edible (and...
Suppose humans have developed the technology to travel between star systems. This might be some science-fiction method like warp drive, jump drive, peanut butter drive, hyperspace drive or whatever...
I'm trying to setup a non-real scenario that doesn't break suspension of disbelief too much past the original idea. But so long as things keep consistency it should be fine. So you are flying a fi...
So, I'd love to have werewolves in the world I'm building, but as it's a sci-fi setting I don't really want them to be magical. I can stomach some pseudoscience, but I want the process to be as rea...
Many sci-fi words use anti-gravity or artificial gravity to manipulate the weight of their ships making flight much easier. Wikipedia even has an article on it which discusses several attempts to m...
Humans have been domesticating carnivores for over 10 000 years. And there are certainly carnivores big enough to ride. The former is the biggest feline ever to exist. They certainly can carry a hu...
Question Context: I've been developing insect-looking bipeds that have evolved on a mostly jungle/ocean planet in addition to small, scattered grasslands. This is justified (from what I've read) b...
So, in my world, a scientist (tries to) invents a machine that will recode your cells in a very particular way, making you immortal. He tests it out on a 13 year old male. It goes....extremely wron...
I read a blog post explaining why interstellar travel is terribly impractical. The short answer is that stars are far away and travelling that far takes a very long time and ridiculous amounts of e...
I have a story in a mediaeval setting with no magic. There are elves, but they are essentially just absurdly long-lived versions of humans with pointy ears and somewhat more acute senses. Unicorns...
How from a evolutionary standpoint hermaphrodite species can exist and have a good genetic diversity, with no self-impregnation? But, this race visually looks more like females, they do have breas...
I am working on the realism of a fictional planet which has an average temperature lower than that of the Last Glacial Maximum (LGM), and possesses a single large supercontinent rather than distrib...
My planet is highly volcanic, as such the atmosphere is filled with gases put off by the volcanoes: Like Earth Nitrogen also makes up most of Marhdii's atmosphere at 43%. Also like Earth, Nitrog...
I'm current planning a story which includes a race of diminutive humanoid aliens, one of whom crash-lands on Earth. They're fully sentient, and have the same average intelligence level as humans. T...
Imagine a large room, perhaps 50 metres in length and 35 in width, with its ceiling 40 metres above the floor. On this ceiling, there are LED lights, rendering the brightness of the room to look so...
One species has two genders, like humans, the other has three(essentially male, female, and one without breeding capabilities that first appears as a genetic quirk but quickly becomes more prominen...
Reality check: Protagonists of my story have a scientific device of a peaceful purpose. Unfortunately, despite the peaceful purpose, activation of the device, as a side-effect releases about 100 ...
In the relatively realistic (hopefully), near future, scifi book I am writing I am at a point where I am describing the observation deck of a large ship belonging to a wealthy "business man" (see s...
Many fictional characters,specially in the anime art have shoulders bigger than any other upper body muscle. Normally the obliques,chest and latissimus dorsi are the biggest muscles in the upper bo...
I have invented a large machine that allows me to create monsters out of blood. These monsters are called golems and are very powerful. My plan is to produce a large number of them to include in my...
I remember playing this game back in 2010-2011, and In minecraft if you found a waterfall you could actually swim it up vertically, it was difficult but possible. Does this apply to real life to...
So I am designing my aliens flash-freeze-on-target mechanism and now I am wondering what would be the more practical use for these flash freezing powers, as a predator or prey. These creatures are...
The TRAPPIST-1 planets are all very close to each other and thus are subjected to strong gravitational forces amongst each other and to the red dwarf they're orbiting. Would it be possible for them...
Usually when a population overgrows it expands in search of new land and if the fields are virgin and empty they become farmland and cities, but if the fields are already occupied and the resources...
Think of Saturn. In this book, some people travel to a gas giant with rings and find an ecosystem in the rings of a planet. It has predators and prey. It has plants and animals. Autotrophs and Het...
