After an age of highly developed technology, including many different satellites in various Earth orbits, humanity loses the technology needed to control those satellites. After many centuries, how...
Living in space can be boring. What are some good home games for people living and working in free fall? I thought of a few - Bocce : in this variant the size of the jack and the player balls i...
A speedometer is a gauge or device used for measuring instantaneous speed of moving vehicle roughly speaking, so for example the reading shown on the speedometer of a car parked at road side displa...
My friends and I are building a world with a 50 mile high volcano on it. The mountain is the result of some bored god deciding to play a joke on everyone. Or, some other god got angry and decided ...
Imagine a spacecraft in a highly eccentric orbit. Say the craft burns at periapsis towards the planet such that its orbital eccentricity does not change and the craft's periapsis moves with the shi...

I'm writing creative text and I'm curious to know, just as possibility, can a galaxy by any chance be formed out of a black hole?
A federation of alien spacefaring nations is doing basically the opposite of prime directive: they are jamming the Solar System, preventing us from leaving it. They are doing so by placing some de...
In the late 23rd century certain groups of mankind stared down the barrel of what may be possible in the future: cross galactic relativistic kill missile storms, gamma-ray Dyson Beams, Kugelblitz b...
Would it be possible for aliens that originated and evolved in a planetary system beyond the ring singularity of a rotating black hole to send individuals out into a normal universe to colonise it?...
Would the principles at work in the theoretical Alcubierre warp drive apply to a slower-than-light starship? I'm building a setting in which FTL communication and travel is impossible, (due to vio...
Having your radiators tactically protected from enemy fire by the armor shape of your space warship is nice, but having a regular one or double-sided radiators is still a vulnerability. Other conce...
In various science fiction works, we see our plucky heroes beaming down to, or flying down to planets other than their own. They meet with the inhabitants there, be they human or otherwise and then...
On the earths surface, radar is pretty sweet. It apparently penetrates the atmosphere well and bounces back and can be detected. I think this has to do with the wavelengths absorbed by our atmosp...
In 1958 the United States Air Force considered a mission to detonate a nuclear device on the surface of the Moon. The endeavour was framed as a booster to American public morale in the wake of the ...
In my world a giant ship attempts to land on a planet, sadly it fails. Fortunately the top half is intact but the bottom is ripped up, holes all over it, basically destroyed except for some lucky s...
What would be the economic trade offs of building fusion powered rockets vs building laser relays across the solar system? What assumptions would you need for each one of these to be the superior o...
I wonder if it is possible to install artificial equipment that would exhaust oxygen into air in otherwise CO2 atmosphere so that locally people could breath in open air without any kind of tent or...
I have settings with orbital colonies around the earth. First off my idea is, if it is not profitable we would not fund it en masse. Therefore I came up with the idea that in the future we discover...
In the near future, humanity has spread out across the Solar System. A new planet is discovered, let's say 30 light years away, that shows it to be Earth-like and could harbor Earth life without to...
The fleet in my setting are forced to leave the planet due to a volatile virus, and leave in pre-prepared spacefaring vessels capable of transporting ten million people per ship. The ships have alg...
The advanced civilization in my story is trying to reach as many galaxies as possible in the next few billions years before the expansion of space has sent those galaxies permanently out of reach w...
We are using a Morris-Throne Wormhole Metric. Let's presume the throat of this wormhole (in internal hyperspace) is short, let's say 1km. Now, as you are travelling through the entrance wormhole,...
The local sapient species on a relatively Earthlike planet has constructed a space elevator. It is anchored along the equator. Due to unfortunate circumstances (and potentially divine intervention)...
The universe as we know it has ended. The concept of "natural" illumination ended when the last red dwarves and quasars died out. Now, only brown dwarves and blackholes dot the empty void that was ...
Starliners are huge colony ships. They carry enough equipment, building materials, embryos, colonists and nutrient rich rations to permanently establish a sizeable colony on a far-flung world. Alth...
In my world a moon is reached and colonised but only in space stations for a long time. They gain the ability to reach the surface and then story happens. It needs to be something that can be bypas...
I have a spaceship which I want to have travel very quickly around a system like our own solar system -- let's say about 10 million miles per minute, which would go from Mars to Earth in ~15 minute...
The crafts would have to contain large farms in order to sustain the immense amount of people, and they'd obviously have to be large and spacious to have good living conditions. I did some research...
I'm not sure if this site or Astronomy would be better, but I figured I would try here instead. I am attempting to create a [semi]plausible star system in Alpha Centauri for a series. The system w...
In the distant future a breakthrough in cryostasis technology can put healthy people into frozen state so that all metabolism halts and cells never age a bit, the spaceship is carrying them across ...
I'm writing a novel set in a post post-apocalyptic world, where society on Earth collapsed a long time ago and has rebuilt itself by the time the novel starts. I need a reason to keep the people ...
I want to write a story taking place on the natural satellite of a gas giant, with said satellite being massive enough to prevent, or at least strongly deter, space travel, such that the resources ...
Given the difficulties in doing things like constructing O'Neil cylinders or habitats on places like Mars, is it at all plausible that current humans could ever really colonize anything in space? I...
Glossing over the technological implications of interstellar travel, what sort of human labor might still be required in a future where we are capable of setting up nigh-fully automated endeavors o...
So given an Earth in our near future, year 2100 or so, where some of our tech has improved to the point where we have robots and the usual sci-fi devices for interfacing with computers. A colony i...
What if there was a binding global resolution passed tomorrow mandating that all countries gradually close down their terrestrial resource extraction sites and instead source from asteroid mines? W...
Many know that the Lantern Corps of DC Comics are capable of constructing objects of any shape or size out of hard light using their power ring fueled by their emotions. However, I'm wondering what...
I'd like to have faster-than-light travel (and communications) be an late-game option for a video game I am working on. The extent of the playable universe is approximately 4 million light years in...
A group of English-speaking settlers travel to the Earth-like exoplanet of Rataan, which is 5 light years away. They board the generation ship Genesis that will reach Rataan in 200 years (0.25% of ...
Many countries, authorities and companies have the concept of a maximum weight limit for manual handling, both to protect their workers and to protect themselves from lawsuits. Interstellar Shippi...
We've found a habitable planet orbiting a red dwarf star some light years away and conditions are Earth-like enough that a colonization project was initiated. Before any humans landed on the planet...
Double or binary planets are a really cool science fiction idea. A second Earth hanging ominously in the sky. Co-orbital or trojan planets are also interesting in that you have them on more or less...
Is there a feasible setup where the Sun has expanded enough to make the Earth uninhabitable, but some of the other rocky bodies in our solar system (past Earth) become more reasonable colonisation ...
I am currently working on a character backstory for somebody whose fictional character gets sent back in time an era before his species existed (essentially to bronze-age times or even earlier, it'...
My idea involves an alien spaceship inside a roughly Earth to Mars sized/massed planet, but the whole planet is displaced when the drive is activated. If you wanted to travel back to our solar syst...
I'm new to this and my scientific knowledge is massively lacking in this area (so please take it easy on me!) I'm writing a historical science-fiction novel. Parts of it set in the past (1977) and ...
Basically, the title. Trying to figure out how reasonable stealth in space would function, and while I have mitigated it, I am looking for methods to improve it. But mainly, is creating a sort of h...
My advanced human civilisation often has high-acceleration ships travelling at near lightspeed. I know that time dilation would have a significant effect on the time experienced by the crews, but I...
Would it be feasible to have an interstellar vessel be constructed in flight after smaller sections are boosted up to speed? The idea here is about using laser sails which would be easier to use wi...
