I'd like to have a community of humans live indefinitely in space habitats (think space stations supporting mining operations in the asteroid belt). The technology would be "day after tomorrow"-le...
Lana Lang (Because no one really gives Lana enough love) is the newest recipient of the superhero lottery. Boasting an impressive repertoire of powers, yes, but there are only a couple of ones we ...
How powerful would a series of explosions have to be to significantly change a planet's axial tilt? In my universe they have highly energy efficient crystals, not only do they store energy but the...
Last Tuesday, as every Halloween, I re-watched the Cowboy Bebop movie. For those who don't know, it is a sci-fi anime set around the solar system in an hypothetical future. This question focuses o...
I was wondering if a creature could use natural armor plating to protect itself from radiation. For some numbers, I would like the creature to survive normally very lethal radiation, 30 Grays, for ...
I was wondering if there was a way for a creature to survive the vacuum of space for ten minutes with only a tank of oxygen and a mask to breathe the oxygen with. The creature comes from an Earth-l...
How can I arrange for a planet to have a much greater temperature range between the poles and the equator without it being tidally locked? Edit: By "much greater" I mean the temperature at the pol...
In this world, a planet with very dense vegetation (earth-tropical-forest-like) and silica containing soil was attacked by spaceships which fired very high energy laser beams across the planet's en...
My question is as stated above: if a planet is tidally locked to its sun, how would the people on the surface, assuming it's habitable, be able to tell time? What devices would they be able to use?...
In the anime Vandread, the antagonists (earthlings) had a goal that I find interesting. So I am going to use them as the premise and hopefully expand it well enough to work for a world I am working...
The inspiration came from the music in the title sequence of the film Alien. The idea is a planet that humans have colonized where it's almost always drizzling slightly. It's always dark but there...
I'm writing a novella for a school competition. My main character is a shape shifter. I am trying to find a plausible scientific explanation for how shape shifting is possible. I tried finding an...
The world consists of actual humans who were moved to another planet by aliens, during biblical times, hence having an influence on their religion. The planet is terraformed with earth-like conditi...
This question is inspired by Green's Volcanoes in Orbit! The premise is that there is a 50-mile-high shield volcano (again, let's ignore the height implausibility) with a slope of about 2-3 degrees...
I'm looking to found a new country on a real-to-life Earth, and I need somewhere to put it. The country is going to be anywhere from 100 to 1000 square miles (250 to 2500 square km) in size. Assume...
The enormous shield volcano that this question was based on was held up by magic or God. It presented some very interesting conditions for alternate worlds so I thought I would develop that train o...
As the title states, is it even possible to remove hazardous air chemicals in Earth? I think I could list the pollutants which I think we could remove, these are the following : Nitrogen oxide...
There was a question recently about gatekeepers controlling the flow of goods between universes. The gatekeepers became a religious order. The premise got me thinking, and I have come to a conundru...
In my story, a team of scientists are sent to an alien world similar to Earth to conduct general research on its environment, ecosystem (that is: its animal- and plant-life), and weather. It is the...
Does anyone have any ideas on a world with clumps of different atmospheres? Like what if a world has weather patterns that move around different atmosphere types; a mostly sulphur atmosphere, oxyge...
Under what conditions would a planet's night sky look like this to the human eye? The angular speed of the stars relative to the planet would need to be high enough for the stars to blur into th...
For my future world, I've decided that coastal cities need fresh water and there isn't enough of it to go around. I don't know how jellyfish work. Is it feasible or completely impossible for sci...
I've answered a few questions with this process but I wanted to see if I could bounce/refine this off the communities more biologically adept members. Basically, it goes like so: As a means o...
Okay, it's a staple amongst certain fantasy settings where you have different races of creatures and beings co-habiting, which leads to certain off-shoots of different races (the half-elf and half-...
I'm wanting to have two regions separated by a large mountain but do not want either side to become a desert. What would the conditions have to be on the desert side for this to be prevented? This ...
