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...
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 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...
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 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'...
I wanted to create an extremely large space city which will be made up of many different large space habitats of ringed and cylindrical varieties. Although each habitat will contain its own city o...
Background I am trying to find a design for a cylindrical habitat that would allow the enclosed cylinder to radiate heat out to space as does the Earth without using mirrors and windows. Problem ...
Say in the future, humanity has developed technology to the point that it allows them to traverse through other universe, each universe having something either drastically different or not so diffe...
I need to know how wide the diameter of a space fountain's* particle stream is in relation to the mass it's trying to support. It would have to lift its mass at least 40000 kilometers. The vacuum...
Background A McKendree cylinder is a rotating cylindrical space habitat comparable to the more well known O'Neill model. It was proposed by NASA engineer Thomas McKendree in 2000 as an update of O...
If you had a device, similar to a Stargate, but that allowed seamless two way transfer, and that could be moved (You could essentially strap a rocket on it, and fuel it from Earth), you could just ...
Let's say a few centuries in the future, we have captured an asteroid into orbit and built a space station out of its material. The station is a ring that encircles the equator in Low Earth Orbit, ...
I'm looking for a more economical and efficient method of making steel for my project Death Star Unlimited, a mega infrastructure orbiting Mars with a mass of 500,000,000 metric ton give or take 1%...
From: https://en.wikipedia.org/wiki/Multiverse The multiverse (or meta-universe) is a hypothetical set of various possible universes including the universe which we live in. Together, these u...
Consider a futuristic world where space travel and colonisation of the solar system's planets is an everyday reality. In space vessels, the airlocks are used quite often to execute people. It's fai...
Would it be possible to build a space elevator off Europa? (The space elevator would only be for the purpose of getting items out of Europa's gravity well relative to Jupiter. At that point, the...
I am struggling to picture what placement of artificial lighting I should use for my O'Neill cylinder design for the daylight hours, a strip light along the centre of the cylinder would obstruct th...
In the story I'm writing, three humans with stone-age technology and no knowledge of space accidentally awaken thousands of cryogenically preserved humans. These humans immediately get to work on...
A habitat/space harbor ring encircles an ice giant crossing both poles (polar orbit) and rotating to create artificial gravity. Can the ring also precess in synchronization with the planet's year,...
The cylinder is 32 km long in total, 8 km in diameter, with 3km long endcaps, resulting in a habital area with a length of 26 km (= and an area of cirka 754 km2). The main body of the cylinder is...
I wish to build a sort of Dyson swarm around the sun. Not to transmit energy, but to put supercomputers in each satellite so they can calculate spatial trajectories. The main idea of the project i...
What happens to small pieces of debris left floating around inside a derelict space station? My space station had 100 people aboard, and due to sabotage, it decompressed and was abandoned. Inside...
My story is set within one solar system, which can be assumed to have a similar composition to that of our own: one Class G star, a handful of rocky inner planets and a handful of gas giants on the...
Assuming a passenger was sitting in an elevator in a rotating wheel space station, as depicted in the movie 2001:A Space Odyssey and based on this question Elevator on rotating wheel space station...
Let's consider an O'Neill cylinder with a radius of 3.2km and length of 20km. In the classic O'Neill design, we have three large axis-aligned windows in the shell, alternating between purlins of ha...
In 2001:A Space Odyssey, from Space Station V the Earth appears to be spinning around a center that is near the edge of the planet. Phone call from space station scene If the same station (300 met...
Imagine we have a sufficiently tall space fountain positioned at either of the Earth's poles, such that the upper station is permanently within view of the sun. A large array of solar panels could ...
The illustrations of O'Neill cylinders I have come across with so far allow unrestricted view through the whole tube. Some are more playful with topography but still, there is a visible end. Are t...
If people were attempting to build a space station beyond the Hill Sphere, (outside of the area where Earth's gravity dominates), and wanted to mine the raw materials for the station from dwarf pla...
We had a long discussion in my office about this - if we were in a smallish 500m diameter O'Neil cylinder would hot air balloons work?
I have seen Isaac Arthurs video of O'Neill cylinders and read through many descriptions, but it still is not clear to me how exaclty the two counter-rotating cylinders are placed in regard to anoth...
A quite common idea to provide "gravitation" in space stations is to make them rotate, so the centrifugal force gives an effective gravitation. A possible design is a ring-shaped space station. No...
Y'all should know by now that I want to build a Death Star ;-) Let's assume that we did that already -- and against the odds, we've built two of them, and they're currently in orbit around a plane...
I'm writing a book that involves having a space station that acts as a way point between Earth and a new planet. (Hard"ish" SF, or as "Hard" as I can make it...) The Station sits at the mouth of a...
Say you've got a space-faring civilization that needs a LOT of power. Sure, fusion is a thing, but there's really not that much helium-3 to be found in our solar system, and it's hard to get. So ...
So I have been doing a lot of reading on space elevators/tethers for a SciFi book I am writing and unfortunately there doesn't seem to be a whole lot of info on building one on Mars rather than Ear...
I have a story idea that involves a human attempt to halt and reverse global climate change. The idea is a simple one - a satellite that partially blocks out the sun. The satellite is located at th...
Could you build a ring around the earth, so that it would just sit in the sky? I'm not talking a geostationary orbit of rubble like the rings around Saturn, but a solid structure just high enough t...
The ISS uses port and starboard to differentiate between the two sides of the station. (The Harmony node photographed after it was attached to its temporary location on the International Space St...
How can I protect a ringworld (which creates 1g artificial gravity and has an earth-like atmosphere) from the things that earth's magnetic field protects us? (using real-world physics)
One of my ongoing projects is what I think of as the "constructed worlds gallery", a series of Megastructures as settings for stories and games, including things like the "Flying Pie-plate" a world...
A common, matter-efficient, science-fiction habitat is a hollow cylinder or ring in space that is spun to simulate the pull of gravity on its interior surface. While for most purposes this artifici...
I was curious: Suppose we built an O'Neill cylinder with an air mixture similar to Earth's (not pure oxygen). Does the air also get "thrown" down towards the floor of an O'Neill cylinder? If I sta...
Is there any reason an elevator, moving from the central hub to the outer ring, would not function on a rotating wheel space station with artificial gravity? Any parameter of the radius or rotatio...
What would happen if the entire inner surface of a Dyson sphere (not necessarily a solid shell, maybe a very dense swarm) would be coated into a highly reflective material? Let's say it can reflec...
For a story I'm working on I'm designing a sattelite to take down infantry from orbit, but without the power to take down tanks or infrastructure. The goal would be to kill off a military base, or ...
If I needed a large area for zero-G training, is there any place to put it on a rotating wheel space station if the hub was needed for docking of spacecraft? I wanted a place on the station that...
Based on Docking on the outer edge of a rotating wheel space station would it be impractical to launch ships off of the outer edge of a rotating wheel space station? Whether launching the ships al...
Assuming such a space station needed to have its central hub not used for docking spacecraft, would it be plausible for a spacecraft to dock on the outer edge of a rotating wheel if the ship approa...
Armageddon is coming. A giant Texas-sized meteorite on a collision course with planet Earth is discovered in 2020. It will hit Earth in 2030 and will wipe out 90% of living things including humanit...
