I'm asking this question about an already-built world, in accordance with Are questions based on movies okay?. One of the most famous props on the television show Doctor Who is the sonic screwdriv...
Imagine we could open a wormhole or a jump point to a new star system. How soon would it be possible to have an accurate map of the major bodies in that system? In sci-fi, this sort of information...
Here's an intriguing thought - I think so anyway. Let's suppose for a minute that there's an Earth-like planet with sentient life orbiting a star near the edge of the Sagittarius Dwarf Spheroidal G...
Basically, my current thought process is to have a virus that causes one to all vital organs to fail upon reacting to its components. It has to make contact with as many people as possible, therefo...
Let me clarify on that title, because this question focuses specifically on vegetables that have not been cultivated for their fruits--like tomatoes, eggplants, peppers, cucumbers and pumpkins--or ...
For my sci-fi world, which spans the entire galaxy, I was wondering if an advanced civilization would build a space probe to explore a star. Would it be necessary and have any scientific benefits, ...
I am interested in finding out if a black hole or mass on the verge of forming a black hole with enough spin could generate enough centrifugal force to change shape into a torus? Specifically I am...
This is possibly not quite the right place to ask this question but it's fundamental to the world I'm working on so here it is; if faced with a potent existential threat, in the form of an outside ...
My scenario is a civilization on a carbon-rich planet. The planet has a hydrocarbon atmosphere, oceans and clouds. Most rocks are carbides. The only flammable substance in such an atmosphere is oxy...
Map is 1000 miles long and wide. In general, do these placements make sense? I'm also wondering: where volcanoes would be? why the coast is full of life and the west dead and barren? where the...
An alien world with a significant amount of tall metal trees allows lightning to occur at lower voltages than usual. How low could that voltage be pushed and still break apart Nitrogen molecules i...
If tiny particles of solid material (the size of sand grains, for instance) were flung into space, would they pose a danger to anything they hit? I'm no physicist, but my understanding is that obj...
I am working out a future scenario in which humans begin to discover alien life; I want their discoveries to be plausible. For example, I've frequently heard that alien life will most likely be ca...
I've been spending a lot of time developing aliens for a comic I'm working on, in the skeletal structure department I've run into a bit of a roadblock, how to design a spine for a species that is k...
I want to kill a huge Dragon. How to do this? The only description currently available of this Dragon is very short: "It looks like a lizard with two wings of bats and he swallowed our ship witho...
Although the fossil fuel coal had been used as a fuel since 1,000 B.C., it wasn't until the arrival of the Industrial Revolution from the mid-1700s through the 1800s that coal began to replace b...
According to an answer to a previous question, it would be comparatively impractical to conduct mining on a rocky planet when there are moons, asteroids, comets, etc. that have smaller mass, so muc...
In my world, humanity has made the ultimate invention: A machine that takes raw elements and converts them into anything one desires, like a universal 3D printer. The only thing it needs is a supp...
In the History Channel program Clash of the Gods, some of the highlit characters have been given some interesting physical liberties. The episode "Minotaur" features King Minos with a meerkat-like...
This is another question about PommeDeTerra: Thanks to the orientation and position of the planet, PommeDeTerra has a habitable island with a temperate climate at it's south pole that looks a l...
I've recently read an article (Source: https://www.livescience.com/22146-why-don-t-any-animals-have-wheels.html) explaining why animals don't have wheels for locomotion, and that legs are common be...
Having in mind a scene from "Avatar: The Last Airbender" where Aang covers his body in a block of ice to float on water I'm wondering if it was possible to get H2O solid at arbitrary temperatures (...
So our muscles run off of oxygen, but I heard from my brother when posing this question (he's a bio major in college) that using phosphorus instead of oxygen to power our muscles would make them fa...
In my world, the main "evil" race lives in a labyrinth like rock formation. They use a method of magic that gives them a hive mind advantage, so they all know how to move around within it. My quest...
I was wondering about feasibility of small 'shell' world build around something very dense, like black hole or some 'artificial mini star' that could also be source of energy, and of course gave us...
