I'm thinking about a design like this generation ship, which obviously has spin gravity. Would the fact that the ship is rotating affect the use of a magnetic sail? The magnetic sail as a sort of...
So I've been thinking about the idea of a series that takes place on a small fleet of generation ships, traveling at around 10% of lightspeed to Proxima Centauri, which should take around half a ce...
An old saying goes that if you have an army, it will want to fight a war. That seems to be true also for our personal army, our immune system: there seems to be various pieces of evidence that man...
How could a generation ship "steal" energy or resources from star systems which it passed without changing velocity?
"The planet moves." Inspired by this link in a comment from Gryphon here, I also see the concept in this question. We've colonized the moons of Jupiter adjusted their orbits to our satisfaction (...
Alright so I'm not really a physics person by any stretch so forgive me if I butcher some physics jargon on this post. So I'm making this hard sci-fi interstellar ship with a rotating habitat that...
Regarding the idea of a generation ship carrying a community of people for thousands of years to another planet: Is there is any material for an engineered structure or set of systems that will re...
On a generation ship, the people living on it need oxygen, lots of oxygen. More than they can realistically carry, thus a generation ship must be able to create breathable air from relatively commo...
A generation spaceship (a spaceship designed for multiple generations of humans to live in) could sail through the galaxy for hundreds of years before finding another planet, let alone a planet wit...
Assuming the ship has access to fusion power, a large volume of solar panels, and crude antimatter power generators (say maybe 1 gram a day per generator, or whatever is reasonable for technologica...
I don't like the direction where mankind is going. We spend more resources to build tools which allow us to watch cat videos than on curing cancer. One day I decided to say enough, and leave this ...
Earth, far future: We built multi generation ship which can get 20 000 people to another solar system in next 20 generations (600 years) For scope of this question assume that ship itself is well ...
I have a handful of immortals that have spent the last 6000 years stuck on planet Earth. They really, want to get out of here. They missed their chance back in Egypt before The Fall of the Pharaohs...
When in space, the amount of force required to move goes down drastically, due to the virtual lack of drag. In this environment, would be feasible for engines in space (more specifically belonging ...
Ok I have a moon, or cored out moon, that is a generation ship. I really do: I built it by mining out one of the rock/ice moons around my solar systems gas giants (not earth's solar system). Its...
Setting So for generations a ship has been traveling through space. After reaching their desired destination you are left with a group of people who have been used to their largest spaces being no...
In the year 21--, a crew of 100 sets out from Earth on the good ship Tenzing Norgay, bound for Epsilon Eridani. The journey is estimated to take . . . well, quite some time, given that it was calcu...
As a source of food, would it be possible to have fish and/or plants living inside a water tank situated between the fusion or fission power plant and the crew quarters of a ship? The ship in ques...
Scientists have just released details on their discovery of inter-galactic baryon material - "Dark Matter" that turns out to be regular matter, except that it is 'dark' - dispersed throughout the i...
You are on a generation ship in interstellar space, between star systems. We know that there are rocks whizzing around out there - escaped asteroids, bashed planets, we have even put a few artifici...
I can easily set a story in a dystopian environment not subject to ethics, but I would rather try to create a backdrop that is as ethical as possible given the requirements. I feel that writing abo...
Context if you're interested In the very near future, a planet teeming with alien life is discovered several light years away from our Solar System - and with a few precautions, it may be habi...
I was wondering if it would make sense to hollow out an asteroid to use for a generation ship? Also, might it be a good idea to use hollow asteroids for any kind of long distance space ship? I'm th...
I'm working on a story set in a generation ship traveling through the stars. Its propulsion is a solar sail, which will accelerate it over many decades to a substantial fraction of the speed of lig...
The energy source both in terms of fuel and electricity on my ship is nuclear fusion. Very precise nuclear fusion: there is no helium fusion until there is absolutely 100% helium in the main fusion...
One thing that necessarily happens on a generation ship is that people die of old age. Now that poses a tension: On one hand, you need to handle the dead with dignity. On the other hand, you probab...
I'm planning on sending a colony ship on an extended, multi-generational voyage to a distant star. My colony ship is an oblate spheroid, 2km long on its long axis and 1km across on its shortest axi...
A generation ship was sent out a long time ago, to colonize a far away planet. However the ship failed to reach its goal due to navigational issues (which also means they didn't have any clue where...
Earth, far future: We built multi generation ship which can get 20 000 people to another solar system in next 20 generations (600 years) For scope of this question assume that ship itself is well ...
The Setting Imagine a generation ship of 10-20 generations (200-400 year trip). The generation ship is divided into living crew and frozen eggs. Upon reaching the destination & for genetic d...
Assumptions Space travel is hard. Interstellar travel takes a long time. Chances for a successful trip and colony becoming self-sustaining are not considered super high. Therefore, each colony ...
I've been thinking that the natural manner for interstellar dispersion of humanity with relatively hard science is with permanently habited nomadic generation ships. Instead of building a ship, goi...
The human race has colonized the solar system with permanent settlements on all of the inner planets and outposts beyond. Vast space stations pepper the voids between orbits and massive mining/ref...
Kaylee is a mechanic on a Generational ship. The ship has several means for propulsion and has a plotted course that goes from star to star, molecular cloud to molecular cloud. It has a Bussard Ram...
Earth is dying. We mis-managed it and brought the whole ecosystem to the edge of total collapse. About 50 years ago, we decided to move humankind to another planet, and now we are almost ready. A ...
