Suppose the Wicked Witch of the West was simply an alien life form that was stranded in Oz. She comes from a race of beings that are water soluble. She would have to be able to resist a small a...
Part 1 On Earth, we have seasons due to our planet's tilt. In my last question, I proposed an alternative world where the seasons were instead caused by an eccentric orbit. Now I'm going for somet...
How to get humans that can change their skin color? Approximately 1.6 million years ago, hominids lost their hair and gained dark skin (so says the New York Times). Evidence shows several several...
What conditions might make a planet more likely to develop silion based life, the factors I need to kmow are listed below Temperature of the planet The solvent that they can use in their biology ...
So let's say that some advanced future civilization is capable of creating and manipulating wormholes, and uses a network of wormholes for their FTL transportation. If an enemy gets too close to o...
If humans hadn't lost their tails and today we had fully prehensile tails as long as 1/2 our body and stronger than an arm, how would the tail of a bodybuilder or just a buff person look? Would tai...
I am making a "structure" out of carbon nanotubes in deep space. This structure can be any shape or design, I just want it big. Big in just one direction is cheating (so no long thin structures),...
So I have a story about humans far off in the future on a different planet that have evolved to be more in tune with electromagnetism and magnetism. Their technology mostly works because of magneti...
On a certain planet, the sole continent of land is a large circumspecting ring about the equatorial regions, with a width averaging 500 miles. Rotational north and south are entirely pelagic. Var...
Suppose I have a time-traveling DeLorean (of all things), and I've used it to travel back to 1955. But then I ran out of juice. Fortunately, I just happen to know that a certain clock tower will be...
I am creating a race of aliens that are amphibious and mammalian in detail, they have six tentacles, bunny ears and also fur covering their bodies. They are about 3-4 ft in length, if this species ...
As we all know, hydrogen and by extension water, gaseous, liquid or frozen, is pretty much everywhere in our solar system besides maybe Mercury. The most abundant source may be the Asteroid Belt, w...
Basically what I'm picturing is a slight variation of the usual model that relies on flux pinning (a.k.a quantum locking) to resist damage. The swarm has a macroscopic "core", some sort of electrom...
What would it look like for a ship with an Alcubierre drive to drop out of FTL both for the passengers, and to an observer (assuming they aren't obliterated)?
Since I'm getting plenty of great for my other question "How can a nine tailed fox catch its prey? Thought I might try to get ideas for both fox-fire and illusions. So far I've thought of biolumin...
This is a spin off from this question here. I want a spaceship or several spaceships to be able to move a planet out of its orbit around another planet. How big could the planet realistically be...
I'm writing a Earth history time travel story, and the main character needs to solve puzzles from each time period he visits. I'm going very far back in history and I'm concerned about being able t...
A common problem I have with modern science fiction and fantasy (Halo, Mass Effect, Narnia etc) is that the aliens and animals are somehow able to speak in perfect human speech. How does an alien o...
Had a random thought. I was wondering if a uranium deposits underwater could result in radiotrophic plants or bacteria to sustain an ecosystem. One issue with this, is radiation has very short att...
In most sci-fi (graphic) novels and films, they often depict the design of the cockpit or captain's bridge in a rather unusual way. A smaller ship such as a fighter or a transport ship usually come...
I want to have two planets orbiting each other, and there is a ring around both of them, is this possible? I know rings are formed inside the Roche limit, so if the ring lies outside the planets, ...
Suppose that I have a spherical space-ship with an approximately 1 kilometer diameter. For some reason I need to park it (unmanned) for a long period (100+ years) fairly close to the Sun. (Half the...
I imagine such a creature would be composed of thousands, possibly millions of planets, gas clouds, asteroids and stars. Almost like a giant living engine powered entirely by gravity. Obviously t...
I am writing up a system of wormhole-based gates to allow "fast travel" in a far-future setting. My description is an extrapolation of the way I understand a flatlander's experience of the followin...
I was wondering whether a planet might exist that has life forms with up to five sexes, with a single organism having three different and independent, functional sets of sexual organs. Presuming in...
