[Question] [ That is to say, could a planet be big enough to have other planets orbiting around, while not orbiting around any star? [Cha 110913](https://en.wikipedia.org/wiki/Cha_110913-773444) seems to be close to what I'm looking for, but its classification is still a bit vague. And if yes, would life be possible,...
[Question] [ So last year I started writing a post-apocalyptic story, and then realized I had no idea what the world was really like, and quite a few things just didn't seem to make sense. One of the biggest that jumped out at me was the abundance of running automobiles tooling around in my story. Which got me thinki...
[Question] [ I have this idea for a world where the creatures, though they look organic externally, are actually mechanical in nature and when damaged reveal their mechanical innards, with pipes pumping coolant instead of veins pumping blood, the damage usually damaging the pipes and making them 'bleed' their coolant...

[Question] [ I have a creature who harvests resin from trees as a building material. These trees are similar to those on Earth, but not identical (I.e. there is biological wiggle room).

[Question] [ Some fish [mouthbrood](https://en.wikipedia.org/wiki/Mouthbrooder). Some amphibians mouthbrood. Crocodilians carry their babies in their mouths to water.

[Question] [ Recently I was talking with a friend of mine on fantasy stuffens. I brought up that its interesting that dwarves are rarely in the desert and he immediately listed reasons why the dwarf build is bad for the desert: Short stumpy legs are bad for the desert and horrible heat dispersion made worse by the ma...
[Question] [ I use forememory instead of foresight, due to how the ability works. A cunning and creative person can remember five minutes into the future, and are smart enough to exploit it in any way possible. For simplicity, I will name the person "Abe". They are the only one with this ability, so others seeing th...

[Question] [ Let's say you had a world much like Tolkien's Middle Earth. Elves, dwarves, orcs, and the like. Now let's say that against all odds, evil sorcerers, heroic blunders, and such that that world managed to achieve a level of technology and civilization equivalent to our own. How would **Elves**, specifically...
[Question] [ In a story I am working on, I need a scene in which one of the main characters finds himself **outside in precarious weather conditions, unable to see unaided much farther out than an armlength or so.** For the purposes of this question the setting is essentially our Earth, and my draft geographical loca...

[Question] [ If hawks or eagles (or any creature that can fly like a hawk) had the same ability to pronounce words as parrots but also had consciousness (what I mean by that is that they can scout and describe the enemy movement to their side), would that extra capability of their brain hinder their flight? The ways ...
[Question] [ I am currently working in a "fantasy" world without any kind of magic and I thought of a race with different skeleton color (blackish in particular but I want to know in general).

[Question] [ So, the world has come down to a crashing halt. Nukes rain down from the sky, after the Cold War finally became a Hot War. Now, humanity is left with a wasteland. After the big one, cities have been mostly abandoned to the dying and the (soon to be) mutants. Lets say you have a man living near a large ci...
[Question] [ I'm writing a novel about a (small) group of people with extraordinarily long lifespans.

It is generally handwa...
[Question] [ It's common trend for many stories within the Urban Fantasy genre to feature various mythological pantheons co-existing with one another.

[Question] [ So, I've got a planet that's basically a junkyard. It's just one big junkyard. People from various space-faring societies dump all the crap there that they don't want to deal with. Derelict spaceships, obsolete tech, that sort of thing. And because the people doing this are lazy, what they basically do i...
[Question] [ How would the fighting population of a race of goblins be different from that of normal humans? Let's name some parameters for these goblins, first: * Small tunnel dwellers: Probably not important to their demographic. Might affect the overall size of their population, though. * Low Sexual Dimorphism: Ma...
[Question] [ Some background information: in this world there are races that are ageless. Meaning they stop aging at what humans consider age 30. This of course means that both men and women remain fertile, essentially indefinitely. This could mean that your great-great-great-great-grandfather could theoretically hav...

[Question] [ Basically, our protagonist wants to get revenge on an evil warlord and his minions (not [the cute kind](https://en.wikipedia.org/wiki/Minions_%28film%29)) for the destruction and butchery of his home village and all those who he loves. He decides to "get biblical on their... I mean them" and begins to pl...
[Question] [ I started a lot more SF stories than I ever completed. The fortnightly challenge topic reminds me of an idea I had around 1986 or so, when the new PC's I was selling featured 640 kilobytes on the motherboard (no expansion card needed), and a Macintosh had a tiny B&W screen and a hard-shell floppy disk th...
[Question] [ A bridge is collapsing, and our poor MC is stuck in the middle. The ground beneath them collapses, but they miraculously are able to climb up the falling debris and safely make it to the main land before the whole bridge is lost.

[Question] [ I have this race of space-dwarves and I need to make them homeless due to technological hubris of some kind: for plot reasons. I think that if they were to attempt to build some kind of Dyson sphere and then it collapsed into the sun it *could* add enough mass to the sun to make it go nova or fizzle out ...
[Question] [ Is there a way for a moon to usually appear relatively similar to our own moon, but occasionally appear [much larger](https://i.stack.imgur.com/03vES.jpg) from the planet's surface without causing natural disasters due to extreme gravitational forces? To be clear, the moon should only appear this way for...
[Question] [ I am more curious about the immediate effects on local and global socio-economics rather than the likelihood of the rest of the world declaring war on China or were the other countries would get their goods from. One day, China stops all exports just out of the blue. The reason why they stopped exporting...
[Question] [ By some means, artificial or naturally occuring, a human inhabited star system has been flung from the Milky Way.

[Question] [ We once lived in a galaxy filled with the wonders of technology indistinguishable from magic. Even the poorest beggar could afford this mass-produced tech. Vidscreens as real as life, longevity infusions and the occasional passage on an FTL ship. But then there was the Fall. Worlds died in torrents of vi...
[Question] [ OK, let’s suppose I have a structurally sound ship—it could take a shaking—and that space debris isn’t a problem.

[Question] [ From my understanding of animals, lifespan is all based on the speed of its metabolic rate. As endothermic animals, mammals live a high-octane life - growing up fast, being quick on activity regardless of the weather and demanding a lot of food in a short period of time. As a result, they, if you will, "...
[Question] [ When you mention livestock you think of creatures such as cows, pigs, sheep, chickens and so on.
