I created this climate map based on the Koppen Climate Classification map. In this scenario Australia is moved 10 degrees of latitude further south and the Lake Eyre basin is filled (shown in map...
How big could a moon be before its orbit became too unstable or tidally locked to a planet about 1.6 times larger than Earth. Planet BlinketyBlink is on a similar orbit (to that of earth's) aroun...
In a story I am writing, some animals (including sentient ones) can touch fire without being harmed. Not any kind of fire, though. They can caress the fire of a candle with a finger, and they can ...
I was thinking of making flying islands part of a planet ring, but the problem was that they wouldn't be able to host life unless they were inside the atmosphere of the planet, but at that point it...
In a far-distant future Pascal enters the bridge of his intelligent space ship. He's a lazy bloke who can't be bothered to sit or stand, so he flicks his fingers and in a moment of Clarkian...
This is a sequel to my previous question How big could a moon be before its orbit became too unstable or tidally locked to its planet OK, let's imagine that the thing everyone thought was a moon w...
Spiders produce silk, a protein fibre able to construct webs and dens. But is there an existing animal (preferably a vertebrate) that would be able to evolve a similar ability of producing a silk-l...
The idea is to have a number of artificial, spherical satellite to have sort of a "spiral" orbit around a Ringworld, such that the inhabitants of each of a number of ring sections see a moon in the...
I've read the other answers relating to this area (and discovered to my disappointment that my great ideas have been done before... hey ho). But I'd like to get the science right. I have a nation ...
The moon seems gigantic and is extremely bright. The planet BlinketyBlink has a mass of 1.6 Earth masses and a single large moon which orbits it at about 240 000 miles/386 242 km. The moon Toten...
Imagine there is a micro-city built on the ocean floor in the pacific ocean covered with a durable dome with a 1 mile radius to keep water out. At this moment let us assume that the dome holds up b...
Its a very wip idea: I have a star that's not very hot, and the planet is very close to it. Can the planet be so close to the star to be livable on the surface, but flying at cruise height(10 km) w...
So, I was wondering if it would be possible for a race of reptilians to live in a climate similar to that of Germany or Scandinavia without having to hibernate for the winter months. They would be ...
I've heard that bodies of water boasting high salinities tend to turn red due to seasonal algae blooms. I have a river in a fantasy setting I'm working on that's blood red year-round, and I want to...
I'd like to use the theoretical graviton particle to give some characters telekinetic abilities. My research so far is this: "¢ Gravitons are a theoretical particle in string theory that causes th...
Since Tolkien put people riding on giant eagles in his books (or maybe even before that), the imaginarium of riding the winds on the back of magnificent birds has generated a plethora of images and...
In a world where the development of internal combustion engines had been seriously delayed (for whatever reason), would it have been possible to power heavier than air aircraft by steam propulsion?...
It's a fairly well-known fact that reptiles are ecotherms, meaning that they require outside sources of heat to stay warm and metabolize. However, being too hot can cause heat sickness (not fun), a...
I have been designing a species of elves with blue skin as one of their most striking features. I'm drawing inspiration from primates that also have blue skin. Think the scrotum of a vervet monkey,...
How intelligent would an animal(land bound animal) have to be to not fear fire? It's unable to make it or control it, but when a person is sitting by one, and while other animals act more traditio...
Picture a band of happy campers, literal campers, sitting around some fires. Suddenly they feel their inner-ear "filling up" and after mere instants the ears begin popping, as if they were inside ...
The classical rigid airship uses a heavy envelope which accounts for the large buoyancy balloon. This comes on account of aerodynamics. My first concept was a thin and long "cigar" where the cockpi...
In my world, there are underground ruins from an ancient civilization. There are giant insect creatures living in these underground cave-like ruins, ranging from the size of a large dog to the size...
Premise: Assume that one man has a genetic mutation such that his gametes (sperm) never have an X-chromosome. Unlike most men (who have a roughly 50/50 chance to sire a male or a female child) t...
Would it be possible to create a constant EM field that disrupts electronics within it in a similar manner to the way an EMP from a nuclear blast does? Or would it be possible to have a planet wh...
