Mars has been colonized, close to a million people are now living above (and below) the martian soil, every few months a ship from Earth arrives with more resource for expansion and more settlers, ...
What is surface to weight ratio needed to help slow the decent onto Mars? Assembled and inflated in space could a blimp be big enough to include everything needed to jump start a colony and land...
I've been reading the book Nomad, and in it a binary pair of black holes is cruising into the solar system, and threatens to slingshot the earth out into deep space That's got me thinking,...
Someone showering after exercise aboard a rotating space station spinning to simulate 1 gravity. How might Coriolis affect jets of water falling within a cubicle of 2 metres in height?
How do you go about building a working Earth-like ocean ecosystem from scratch in Europa's subsurface ocean? On Earth, abyssopelagic species have evolved to live more than 6km below the surface. A...
I have developed a fictional planet with the following atmospheric composition; 60.4% Nitrogen 27.6% Oxygen 9.8% Xenon 1.5% Water Vapor 0.64% Argon 0.06% Carbon Dioxide Is this breathable to hu...
I would like my human colonists to settle on the high plateaus (2500-3000m above sea level) of my planet thus never meeting the civilization living in the lowlands (in a huge forest so they aren't ...
Let us assume that in the future, there is a formerly human colony on Mars that has existed there for some centuries. The people of this world have had time to adapt to the lower gravity over at le...
Giant dome concepts are beautiful, but I can't help but wonder how they could be so fragile. If there is even the tiniest rip, the whole thing would rapidly decompress. How would you protect agains...
So I my question is quite simple. With current technology or technology that we are likely to gain this century would it be easier for Lunar colonization programs to develop wheeled vehicles or wal...
A civilization of land-living humanoids occupies a patch of land on a continent (patch of land size: a few US States, let's say Montanas) and, without even exploring the continent fully, develops s...
My story setting's group of AIs and brain-uploaded humans wants to colonize space. They have an advantage over us, meat humans, because they don't need conventional life support (air, water, sewage...
Spaceships are a peculiar thing; as are the Humies - the hardy folks working and living inside these hunks of metal for weeks or months at a time. Ironically in space living-space is at a premium. ...
Given the amazing computational power of Matrioshka Brains (M-brains), all the amazing things it can do, including but not limited to the following. Allotting space for an almost perfect simulati...
Let's say in the year 2000 we launch a ship to some distant part of the galaxy. If the ship travels with a constant 1 g acceleration for like 28 years (accelerating halfway then decelerating), then...
This is something that is starting to bug me, I'm creating a universe in which space travel is cheap and comfortable and space habitats can be built roomy enough that no-one actually needs to live ...
A colony of space travelers makes their way to their new home planet. After landing and establishing their base camp, a wood worker begins to cut down trees and notices that none of the trees have ...
According to Elon Musk's plans/overall mission, humans could better survive as species if we inhabited more than one planet. So far so good, he proposes settling a million people in a first city a...
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...
For the obvious reason of weight, our modern space stations and satellites are made out of metal or lightweight compounds to reduce cost. In a quick Google search, about $20,000 per kg is the cost,...
In Warlords I envisioned the "outermost colonies" around Neptune and Uranus to be a political faction of their own. Separate from the inner planets (Hegemony) and the Jovian and Saturnian leagues. ...
In Warlords poorer families in the belt or some of the colonies are not able (for whatever reason) to pay for 'gravity treatments' or possibly helpful drugs and are forced to live and raise their c...
I created the above illustration to help convey my meaning, here is what everything means so that you can read it effectively: E = Earth V = Venus M = Mars The dots in the lower left hand cor...
I'm writing the last issue of my comic and I'm in trouble. My villain is a member of a cosmic cult that wants to absorb everything in the universe to create a conceptual/energy pangea out of space ...
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...
For some time I've been working on a universe with non-instantaneous Faster-Than-Light travel, but I've decided to open a new universe with instantaneous travel. So I'm working on the differences t...
I am envisioning a habitable world with an atmosphere comparable to earth's in which one day is extremely long (>100 earth years). Human settlers have successfully colonized a small portion of t...
Background: The main asteroid belt between Mars and Jupiter is the closest and richest source of non terrestrial resources to Earth in the solar system. Even though it is vast its resources are ob...
Will be possible in the far future to use megascale engineering to create an artificial hollow moon to give Earth a big moon in the sky like in billion years ago? Since it would be hollow, it would...
Okay, so I have a species of tree that's absolutely enormous, 1-5km tall when fully matured. Its immense size is supported by a large base, bark that incorporates a 2-d carbon lattice for strength ...
Geckos use the van der Waal force to stick to things, an effect that humans can replicate and make various materials that utilize such (like extra sticky gloves). My question is, would these work i...
I mean in the far future megascale be advanced enough to allow the construction of a ring world around Earth or around a low mass star( a red dwarf for exemple). If yes, how big Earth would look f...
This question would be best answered for the time period of our first colonized planet, which will most likely be Mars. With the thinner atmosphere, weaker gravity, low oxygen, and the bodily damag...
My thoughts go like this: I postulate a superintelligent rational agent, that is given, or assumes, control over its mother civilization. I call this agent "the Ruler". I postulate that in order ...
In the near future, say about 50 years, the most powerful governments are starting to compete for control of interstellar resources. The first step is to send a probe or probes to a neighbouring st...
In the year 2340 on the planet Ionia, a small colony of about 20,000 people was founded. They were camped out near a small lake between two canyons. The colonist all came from advanced planets like...
Let's say that at an asteroid mining site, the workers live in a rotating wheel space station that can produce 1g. They use Earth's 24 hour day, and for 8 hours a day, people go to the asteroid to ...
My story is set in the future where space travel is cheap and humanity has colonized Mars and some parts of the asteroid belt. Asteroid colonies can grow their own staple food, but crops that requi...
Solar wind density is very low even at Venus it is only 10 or so H+ ions per cm$^3$ but it is moving at a brisk clip of 400 km/s for the slow wind and 750 or so for the fast wind. So (feel free to ...
A rare opportunity to send a colony ship off-Earth arose. The target is a somewhat Earth-like planet, with the exception that it was apparently conceived by George Lucas, as it only has one climat...
So, I'm writing about the siege of an asteroid base. This asteroid is near the outer edge an asteroid belt at the solar radiation equivalent of Saturn's orbit from its star (although the raw distan...
This is the sister topic to this question: What are the military pros and cons of colonizing a low gravity world vs a high gravity one? The specific question being asked here is, what specific eco...
I've seen this question raised in several different bits of sci fi media. In games its often that low gravity = lower construction cost or some such. But I've begun to wonder, is it really that cut...
The context: There is a population of people surviving on a lunar-analogue's surface, descended from the crew of a crashed spaceship. The rest of their society is not relevant to the question, but...
Premise In the movie Gravity, gravity embodies the persona of the film by virtue of its absence. It purportedly leaves the audience with a sense of fear of the chaotic zero-G environment and likew...
Humans with a level of technology roughly equal to the present day, not more than a decade or two more advanced (e.g. they might have slightly more efficient rockets, or a more miniaturized comm sy...
A McKendree cylinder is a rotating space station that is 920 km (580 miles) in diameter, and 4600 km (2900 miles) in length. This version would orbit the sun at 1 AU (at the same distance as earth...
Here's the situation: Mars has been colonized in the near future "“ tens or hundreds of thousands of people live on Mars. For political reasons, EarthGov is against sending weapons to Mars; and, ...
On earth, all sorts of machines require heavy oils and lubricants in order to function correctly, be it bearing grease, engine oil, transmission fluid or hydraulic oil, the majority of which are pr...
The story will take place near a galaxy filled with space faring civilizations. In this galaxy, a small group of scientists realize that their side is on the losing side of a war that will probabl...
