I am writing a fiction about Mars, 300 yrs after colonization. Earth turns hyper-fundamental and cuts off all communication, so they've been on their own for the past two centuries. In constructing...
Set in the year 2216 C.E. Imagine a spacecraft with a crew of twenty is leaving for Enceladus, moon of Saturn which is estimated 1.272 billions km away in a matter of months using the next generat...
So let's say you have a Dyson sphere that is 5 kilometers thick . Now, it isn't solid. It's meant to be inhabited. There's the inner shell which is completely covered with solar panels and any oth...
I am making design of a fictional doomsday weapon which is like a miniature version of Death star's beam. I.e it can rip apart chunks of planet and impart significant change in its mass. However ...
I want to build a big structure that will be visible from space. A object would need to be very large, maybe kilometers across, to be visible from, let's say, the ISS (which orbits at an average he...
Which direction is the best way to go if you were to have to leave Sol and travel 500 ly away to find habitable planets to set up long term colonies? Core-ward? Rim-ward? Towards the core through ...
As a high mass star which have already burnt through all of the lighter elements and is now building up iron, the fusion reaction will no longer produce sufficient energy to counter its own weight....
Newton who laid out a set of mathematical rules to predict the motion of objects from a falling apple to planets orbiting the Sun, however it was Einstein who described how two masses tend to accel...
Assuming the feasibility of utilizing a brown dwarf for a gravity assisted slingshot, or Oberth Maneuver, what sort of hazards/difficulties could one expect during such a maneuver? EDIT: To make ...
I am facing a great difficulty to come up with a working principle for a permanent force field on my spaceship which will only permits guest while simultaneously deny strangers or foe. The followin...
Let's suppose anti-gravity/gravity-manipulation/telekinetic technology is found in the near future. It allows to move large ships (thousands tons) into space from the surface of the Earth with re...
If force fields haven't been invented and ships must be able to deploy and return too fast for doors, how might a capital ship be able to protect its hangar from space debris and opposing fighters
In this world, as soon as humans invent FTL, they launch "telescope-satellites" (I don't know what to call them) out in several directions. They travel at 10c, can communicate instantly with Earth,...
Let's say you're an alien and you want to make sure your species outlives your planet or whatever disaster you currently face, whether it be natural or engineered. You load up a bunch of self-repli...
In context, I need to transport a package that has gotten very close to the sun, and I've chosen to use a wormhole. What I need to know is if there is a certain distance that needs to be considere...
I'm working on a sci-fi/fantasy world set in a solar system with a few habital, currently-being-colonized planets. Most of the action will be taking place on the surface of one of them, but I want ...
In my world there exists a planet called Solara Prime. The planet orbits a large yellow star, healthy and capable of sustaining the system. There is one planet and 4 moons whose orbits are roughl...
For the sake of simplicity, my species is similar to humans but far more advanced. We will also assume that they live in a solar system similar to ours, and that they are advanced enough that they ...
(First time posting on worldbuilding, be gentle!) For reasons currently unimportant, Earth has been encased in a solid shell which is for all intents and purposes completely invulnerable. The shel...
What would be the impact on modern civilisation be if a benevolent inventor gave the world the ability to travel around the solar system quickly and cheaply. If over the next five years this tech...
Imagine the following situation: There is a global catastrophe that will destroy the earth and there is a habitable planet in reach for spaceships. But it is technically possible to bring only 50,0...
It's the near future, and Bob goes for a spacewalk outside the International Space Station or Space Shuttle or some similar type of realistic space craft. Suddenly, and unfortunately, Bob goes spac...
Superconductors will be a revolutionary enabling technology for many aspects of space construction. One such use is a magnetic field to protect a craft from solar activity, in the same manner that...
Having recently learned about the Interplanetary Internet in development by NASA's Jet Propulsion Laboratory, and inspired by Kim Stanley Robinson's novel 2312, I began to wonder about the actual r...
I'm looking for some data to create my own sci-fi setting, but I want to base it on real world as much as possible. Also, I don't want to come up with any arbitrary year like 3290 with no backgroun...
We all know (or know how to find) the "rocket equation" that drives the design of a conventional rocket, and we've gone over such things as "specific impulse" and the difference between fuel and re...
Imagine a world in which earth has started to colonize other worlds slowly, though the expense to send ships to other worlds is extremely high, and without FTL drive it takes some times to create a...
In this world FTL travel is accomplished by entering an alternate dimension, let's call Aqua. Aqua is a very simple, albeit strange dimension. A great expanse of water as far as civilization has ma...
There seem to be honest scientific exploration in the field of the alcubierre warp drive if you believe some articles on the net. So to be a little bit scientific accurate in a story using it, I wo...
I've asked another question about trinary planet systems which turned out to not be possible. Is there a way for three worlds to co exist within sight of each other? Sight being defined as making ...
The type of economy where your mining operation takes years just to start yielding marketable product, let alone generate revenue, because the speed of light makes the economic feasibility of inter...
A not widely accepted psycho-social phenomenon but one our descendents might sometime face, the Three Generation Rule states: that the degree of social discipline needed for a space habitat to ...
I have three planets. Let's call them Un, Deux and Trois. Is it feasible for all three to be orbiting one another, close enough to be seen clearly by eye? All three are large enough to be earth eq...
So humanity has decided to reach for the stars, they can't get anywhere near light speed but that hasn't stopped them. The plan is to create a self sustaining ship and attach it to a large sungraz...
Coronal Mass Ejection and solar flare produced on the surface of the Sun often can cause disruption to our electronic equipments especially the communication service if it was directed towards Eart...
What type of extraterrestrial body could successfully pierce through one side of an Earth-like planet, go through all strata, through the core, and then continuing through the strata and through th...
I'm trying do design a feasible passenger/cargo spacecraft stationed on a space station. It's a far future setting, but I'd like to stay as close to real physics as possible, specifically, anti-g...
So I was reading through some stuff and I though to myself, "could there be a square object in space?"
I am writing a science fiction short story, which is loosely about terraforming. The drama takes place on a terraforming site, which has been halted, in its early phases, due to the discovery that ...
Set in year 2615 A.D. humans have colonized nearby star systems, we can travel between different star systems using artificial wormholes. A spaceship leaving Solar system for Alpha Centauri have to...
I'm trying to plan a rotating wheel space station for a project. It should be noted that I have to stay as close to real physics as possible, although it takes place in far future. The space statio...
Disregarding the fact that we can't create a 'star' on earth, what would happen when a mini star is created on earth with some hocus pocus, technology humanity developed 4 billion years later and E...
If on a water covered planet, an aquatic species such as the merfolk evolved sapience and now wishes to go into space, how would their spaceship take into account the lack of land? How would a spac...
Another question made me remember this. Consider a sizable base (building, station) in the atmosphere of a gas giant planet. It should hold a staff of a couple hundred, with supplies and scientifi...
Orbital construction facilities have a great many advantages over ground based ones: You can use materials from space without having to drag them up the gravity well, you can make vessels that don'...
I'm currently working on an idea for a ring world. Thus far I've worked out the following things: Radius of 1 AU Width of half the circumference of Earth 2000km high walls across the rims to keep...
Like this question I'm wondering about design considerations for an intelligent aquatic species that wants to travel into space. Would they have to try and create special body suits to keep moistur...
If humanity decided right now that they wanted to become a space empire and colonize the entire solar system would they be able to do it? One of the biggest problems with theoretically colonizing M...
So I've got a bunch of freeze-dried colonists traveling in torpor to a solar system 55 light years away at 92% c. From an outsider's perspective it takes them sixty years to get there, but how long...
The concept of "age" on Earth is based on the number of revolutions the planet has completed since one's birth. In a setting where interstellar colonies exists, of even in a setting where multiple ...
