I am creating a history for my galactic civilization, and was thinking that the first colonization ship might be launched around the year 2200. World War Three Just a few years from now, a third ...
OK, let's say that you have an interstellar human population. You've got people who live on different planets in various systems, but you also have people living in space stations in different syst...
Assuming a civilization has the capacity to build space vessels designed to travel from one solar system to another, what is the technological difference between traveling at 50% light speed and tr...
The Humern empire uses Photonic Railways to transport its unimaginably vast cargo containers from one solar system to the next. These ships can reach truly staggering velocities (>0.8c even for ...
In my story, I have two huge generation ships racing each other to another star system. Assume they are on an exactly parallel path, neck-and-neck, about one astronomical unit apart. They are trave...
There exists a Universe in which all of outer-space is filled with some form of human-breathable air. Theoretically, you could fly a Zeppelin up there and explore other worlds, with a sufficiently ...
Established rules for the universe: FTL travel exists with special drives, special artificial generated wormhole like tunnels where space ships can break the laws of physics. Engines runs hot, bu...
A wormhole usually helps us to create a shortcut to a distant object through a higher dimensional space. Can the time factor in that higher dimensional space differ from our three-dimensional spac...
I am working on a story and came up with a doubt regarding an explanation given for time travel using wormholes as portals. The below given is taken from Wikipedia link: https://en.m.wikipedia.org...
I'm building a sci-fi world set a couple hundred years into the future. If humans were to suddenly discover FTL space travel (which are handwaved away as generic sci-fi warp speed or something) in ...
I have a character who ends up jumping backwards in time by 24 hours. Essentially nothing else changes, but the character has their jPhone in their pocket at the time of the jump. How functional sh...
I am looking for medically viable reasons why we might discover it to be more difficult than expected to bring pregnancies to term in space. This is for a society based approximately 75 years in th...
The question, Reference to Earth in Intergalactic Universe illuminates the shortcomings of the term "light-year", which defines a distance by mixing the universally constant speed of light in a vac...
I'm an aspiring author, aiming to determine the physical realism of certain fictional concepts within a constructed universe identical to our own. There are many contingent ideas which I must expla...
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...
The term "light year" is used a lot in futuristic writings that focus on space, but light years are defined based on the length of a single year on Earth. Would that not make the entire measurement...
Malgrovian gliders inhabit the middle layers of the atmosphere of Malgrov, a gas dwarf. They spend most of their life gliding, preying on giant balloon-like floating lifeforms. When they get olde...
The idea of an elevator reaching to the near cosmos is very tantalizing when trying to think of ways off planet. A major draw back to this idea is that a long, thin tower into the atmosphere seem l...
While on a space mission to Neptune, you accidentally broke your tether on the way. After a couple of hours floating, you were hit by an asteroid. You passed out. When you are conscious again, yo...
If we want to be realistic, we imagine ships pushing stuff out the back and relying on the conservation of momentum to move forward. Gravitational waves carry momentum. Are they viable as a kind o...
(This question is not about getting scrap metal out of orbit and recycling it: please see the second and third sections of the question text.) Consider an object which was not designed for, or ha...
Let's just take antimatter off the table right now. As I've learned recently, it's hard to make, expensive as hell and even more volatile, and you can never get more energy out of it than you put i...
I'm curious what might need to be considered if a group were exploring the vicinity if a neutron star. Gravitational waves and radiation could be dangers, but what else? Is it possible that habit...
Would a starship that was propelled by magnetic monopoles fly faster and longer than ion engines (assuming magnetic monopoles exist) of course.
I was reading the Q/A on water as radiation shielding. The prime answer went in to detail on the cost to lift water from Earth which is cost prohibitive, but how feasible is it to get the water fr...
Faster than light travel is a really cool thing to have in sci-fi settings. It allows humans, in relatable time scales, to travel the galaxy and see a variety of worlds. It allows for conflicts spa...
As stated in the topic: I would like to have Project Olympus-style space stations served by Apollo-like spacecraft in a world where neither nuclear power (and weapons) nor transistors were develope...
With our current technology we're able to travel through our Solar System (and beyond) during at least a human lifetime. Is it physically possible that a star system has more intelligent lifeforms...
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...
So last year I started writing a post-apocalyptic story, and then realized I had no idea what the world was really like, and quite a few things just didn't seem to make sense. One of the biggest t...
I was wondering if it is plausible for a civilization to go from the end of the stone age to the space age from 6,000 years to 10,000 years. I was thinking this planet's star was starting to die, a...
The Humern Empire is a vast, well established empire that spans the galaxy. Despite having no FTL travel they have kept their empire together with a series of subluminal transport methods. Heavy c...
A while back I saw this video talking about the habitability of double planets and Rocheworlds. I haven't seen any questions about the latter case here, so I decided to take a swing at it. For so...
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...
A couple days ago, I posted this question about what it would feel like to walk on a Rocheworld. For some background, a Rocheworld is a double planet system where the two planets are so close toge...
Soft sci-fi uses inertial dampeners. Harder sci-fi uses stuff like advanced crash couches, robotic exoskeletons, or (my personal favorite) drug cocktails filled with stimulants and other medication...
I was reading an article that said pulsars could be used in the far future, by travelers, by acting as "lighthouses" in space and aiding in interstellar travel. In a galaxy wide civilization, would...
I'm working on a universe where FTL exists but arrival times can be unpredictable to say the least. On average FTL trips are conducted at 4C but ships can take much longer to arrive than that speed...
In my story, I have a slower-than-light starship (traveling at 0.6 $c$) going to Alpha Centauri A. There are several planets around the star. The target planet is a terrestrial, habitable world orb...
In space-trading games like Escape Velocity, Elite: Dangerous & others, cheap FTL exists, but lags in other advancements results in a playable environment that is politically fractured and not ...
Humans have achieved FTL and have colonized several planets in our greater stellar neighborhood. While we have discovered several planets that harbor life as we know it, we have not yet discovered ...
Is there any real technology, experimental or conceptual, that can prolong a person's survivability in outer space in case of sudden life support failure? Something that is also easy to wear or imp...
I'm from an impatient, short lived, and cheap species known as human and while I've developed the means to travel the galaxy, I'm pissed at it. It knows what it did. So I've had enough. I'm lookin...
I'm looking for some reasons that could force a spaceship to land at the nearest planet and cut all connections with the homeland planet, so all the crew will be force to settle at the planet for a...
I am writing a Sci-fi/detective story and I'm wondering if Quantum Entanglement is a feasible means of FTL travel. (I know very little on the subject so if no is the answer please suggest a possibl...
This is my first post, I apologize in advance if my English is not accurate, it is not my first language. My question is: in a world where very advanced civilizations have achieved intergalactic t...
In a world where torch ships sometimes will accelerate over 10Gs for hours, maybe sometimes days on end. Is there any way to keep the crew alive and preferably fully functional in during such hars...
While trying to figure out a way that individuals could own spacecraft in my sci-fi setting without having access to things that could double as weapons of mass destruction, I settled on the widesp...
What other ways are there to save a human for a very long time. I know only about cryostasis. Let's say we have a spaceship traveling several hundred light years to a distant galaxy.
In my world ... Actually, in every hard sci-fi world with casual interplanetary travel, the G-force involved in acceleration would becomes so high that no unmodified human being could realistically...
