In my universe there are more than just one FTL method: Wormholes, Warp, Hyperspace and more. The thing is I need to predict the destination of an enemy fleet. I only can think about spies and h...
So let's say that some advanced future civilization is capable of creating and manipulating wormholes, and uses a network of wormholes for their FTL transportation. If an enemy gets too close to o...
As we all know, hydrogen and by extension water, gaseous, liquid or frozen, is pretty much everywhere in our solar system besides maybe Mercury. The most abundant source may be the Asteroid Belt, w...
By the time we develop the technologies necessary for travelling between stars, I think it is fairly likely that we would have already developed the technology to digitally augment, edit, and uploa...
A person is traveling in a space craft that was designed and built by sufficiently advanced aliens. This space craft left from Earth and is capable of traveling infinitely close to the speed of lig...
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 ...
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...
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,...
How would I future-proof a complex machine or set of machines so that they will still be running 2000-3000 years from now? Is this possible with our current level of engineering and we just don't d...
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...
Major William die in a combat versus aliens. Now he have the capacity to wake up on the same point of time every time he dies. (Movie: Edge of tomorrow) He uses this power to win the war, but he h...
And I mean faaaaar future. Like, twenty thousand years minimum. 13 million years at maximum. Let's say the Earth is doomed and to avoid the impending extinction of the human race, we throw most o...
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...
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...
I am a clockmaker: I work with time and can control it on a small scale. One of my powers allow me to return some minutes back in time after having experienced my death, but I remember everything ...
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...
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...
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 story situation is that a generation ship is headed to another solar system where there are several planets in the star's habitable zone and once the ship arrives, it will approach these planet...
My idea was to use 2 stages for an interstellar spacecraft (particularly the Orion Drive) and use it in a way similar to Project: Daedalus. Phase 1 would involve accelerating to cruising speed foll...
I have a humanoid individual who for various reasons finds themselves in low orbit with no ship or shuttle or tech to take them down The society they come from is about renaissance era level (b...
Would it be possible to move Ganymede into Mars' orbit causing them to fuse together like the two proto moons of earth? The new planet "Marmede" would have a mass equal to 13.2 % of Earth. Ho...
Briefly on world setting: Roughly classical age technology, magic is rare, difficult and shunned, flora and fauna is inspired by a remix of the Neogene period. Practical concerns for long distance...
Recently I have become obsessed with the idea of twin sapient species developing on separate planets of the same horseshoe orbit. As I was considering the technological advancement of this planet, ...
A scientist has recently invented a gravity machine. This machine pulls all mass within a certain radius (say 50 feet?) towards it at an adjustable rate. The machine can... create as strong a g...
While I do know that there is no possible explanation for how we might wake someone up from such a long sleep, I was wondering what food would be edible after one million or so years where the huma...
In Mercury's orbit around the Sun (Solar orbit, not Mercurial orbit), what are the conditions like? What shielding or heat management would be required for a manned spacecraft? Could a spacesuited ...
In a setting I've been working with, I sought a method of sublight travel that wasn't crazy engines or magic. I've already got FTL using a different method than the Alcubierre drive, so it wouldn't...
A spaceship of several kilometers length is accelerating to a very high fraction of $c$ (basically as close as they can possibly get). Which problems can the machinery and the crew encounter? And...
Some days ago I had a discussion with a friend about possible alien life forms. He was stating that there anywhere could be lifeforms that do interplanetary or even interstellar travel by jumping ...
A Russian billionaire wants to send postage stamp-sized probes off to Alpha Centauri using meter-square light sails. Regardless of the practicality of such an attempt, is there a lot to be gained ...
It's the year 2100, oil reserves are mostly used up. In this hard times Evil Corp has invented time travel and it send back engineers and material to drill for oil in the Creaceous. The question:...
Building from this and this, given an aquatic civilization somehow manages to forge tools and build computers, could it build space-faring devices? Also another development that would come earlier...
In this answer to another question, solar system-scale rail gun acceleration (and deceleration) was brought up as an alternative, and I found this intriguing. It's worth another question at least....
One day in the year 1980 humans receive a message from an alien race. It reads a little something like this: Hey guys, real sorry, but a weapon we launched in an excercise malfunctioned and is ...
I've just read this article and watched the accompanying video. Heady stuff, for sure. I'm particularly intrigued by the concept of a "solar gravitational lens telescope" somewhere out near the h...
Let's consider DCR-97, HMSS Liberty, 300 kilotonnes (or 300 Gg) of dreadnought-carrier ship. It's a big one. Let's say it can move forward. Let's say it could potentially move backward, or at the ...
There it is. The elusive Ersa 772. Filled with an estimated $15 trillion in precious metals, mining that asteroid could make you the richest man on this side of the galaxy. You have all of the fund...
There is an emergency on board the ISS. Astronauts can´t evacuate and they will die within five days if critical repairs are not made. Fortunately an automated cargo spacecraft, like Cygnuss or P...
Another question on this site deals with the question of interstellar trade without faster than light travel. I'd like inspiration for a related but more generic question. Why would people choose t...
The situation is bad, human kind have waited to the last minute (literally) with building the huge ship that is supposed to save man kind. The sun goes nova, nothing can stop that but the ship has ...
I want my actors in outer space but I don't want them roaming around freely. Like, if the actors were in a building, there would be walls, doors, elevators. If they were on a land, there would be ...
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...
I have two binary planets, with technological level of about the present day. They've developed communication between the two planets, and scientists are trying to develop a method of getting peopl...
Let's say I happen to find myself outside of earth's atmosphere [right at the Kármán line 100km up] one night and don't wish to cause a fuss as I descend to my home. I am stationary in regards to...
My NASA-like scientists in a system far, far away, but otherwise similar to us today, understand that their nearest sister planet, Sunev, is habitable for mankind. With one exception: it is almost...
