This is something that doesn't seem to be mentioned yet, and I'm not sure if it's a problem, but here's what I'm wondering: If the city is alone out in deep space, how would you find it? This is ...
I think the best way to make humans give up their humanity is to offer them something better. Say, for instance, you define a human as a creature that walks on two legs (thank you Animal Farm). T...
So, imagine a team of space marines, fighting some sort of space bug zombies on a planet's moon. Things are going pretty bad for them, and the last surviving protagonists are running for their live...
This question may be a bit broad, but I'm basically wondering what minimal things humans need to have in an atmosphere in order to survive. Let's assume we have Earthlike gravity, and are only deal...
It seems to me like one of the major obstacles to terraforming a planet is to give it a magnetosphere. In our solar system, this is accomplished naturally either by a hot iron core (for example, Ea...
So, I know that the universe is expanding, and that that means that things are generally getting further apart as time goes on. What I'm having difficulty with, however, is figuring out just how mu...
So let's say you live in a terrifying post-apocalyptic world. For whatever reason, this world is now infested with cockroaches the size of chickens (similar to radroaches from the Fallout games, bu...
This is a pretty simple question, but initial research only seems to provide the opposite end of the spectrum. What I'm wondering is if there are any known side effects of living in an environment ...
I have a world in mind that is essentially a planet-wide underground ocean. The planet doesn't have a strong magnetic field, so radiation on the surface is too high to allow life, but what I'm thin...
I'm trying to flesh out the history of a fictional galactic society, specifically the initial settlements and inhabited worlds. Something that I thought would be important to settlers would be an a...
Someone has created an AI of human-level intelligence, and within hours this AI has grown in intelligence and power to the point that human life no longer seems so sacred. In an instant, all life o...
According to Wikipedia and this answer, the Moon is orbiting the Earth at a distance around 20 times greater than than the point where it would break up. As far as I can tell, that means in a ficti...
One of the theories behind the extinction of the dinosaurs is the eruption of one or a series of volcanoes. Supposedly the ash expelled by these eruptions blocked out the sun, killing plants and th...
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...
I recently envisioned a fight scene in which the three main characters are in a bar on a spaceship when about a dozen space marines ambush them. They take cover behind the bar, but without weapons ...
In a futuristic sci-fi world (galaxy?) I'm building, warfare has become highly regulated and commercialized. When two corporations meet on a deserted planet to do battle, they're followed by all so...
So, let's assume you've cobbled together an interplanetary empire without using transportation methods that violate causality or have the power to blow up stars. You may feel pretty proud of yourse...
I'm sure there have been questions on here about fire-breathing dragons, and I recently saw a question about a lightning-breathing dragon, but back in fifth grade I wrote a 150-page story about a d...
Let's say you're a soldier in a science-fiction war. Everything is relatively similar to how wars are fought today, except that when you die, your likeness and memories are imprinted onto a flash-c...
Inspired by the many great questions asked for this fortnight's tag challenge, I got to thinking, could a plant develop/evolve to eventually consume an entire planet, and keep on living? What I mea...
Something I realized not too long ago about a spacefaring society is that while a lot of technology is going to feel advanced, a lot more is going to feel ancient just because of all the hurdles it...
