In my book which is set in the near future (some hundreds years from today) the mankind has mastered interplanetary travel. Although the travel to let's say Pluto is possible, it still takes severa...
Set in the not so distant future, space travel becomes commonplace but is limited within the heliosphere. I'm thinking since it is fuel efficient and more economical to use gravity assist to slow d...
Currently, chemical rockets have taken men to Earth orbit and the moon by combusting rocket fuel to generate thrust. Even if we develop more efficient rocket fuels and can create significantly la...
Is it theoretically possible to extract all ice and water from moons with subsurface oceans like Ganymede or Enceladus? What would the consequences of isostatic rebounding be if this was done on ...
I want to incorporate hot air balloons as a means of common travel in my fantasy world, but I recognize that hot air balloons aren't really "propel-able". My question is, how would someone hypothet...
My knowledge of Stirling engines is that they work via a heat difference and are extremely heavy when used on a larger scale. This makes the use of them on vehicles a strange choice when there are ...
Most planetary rings are rich in water in the form of ice, especially now we are running low on freshwater reserves on Earth. Imagine someone discovered a huge chunk of meteorite consisting of a wh...
I have a ship that begins the equation traveling at 50 percent the speed of light, but decelerating constantly to finally land on a certain planet (towards which it is moving the entire time). It b...
Let's say that a civilization has access to FTL. Let's say it is instantaneous so travel time between solar systems isn't a factor. How long would it take for them to spread out from their home sol...
In the story I'm writing, three humans with stone-age technology and no knowledge of space accidentally awaken thousands of cryogenically preserved humans. These humans immediately get to work on...
So, let's suppose I finally made it. A creature that's very agile, able to resist most small-arms fire and has a whale-oil breath weapon. Flight is solved with bones, as strong as carbon fiber, (la...
First, a clarification: Dwarfism is the umbrella term for 200+ medical conditions that result in short stature. Since this is Worldbuilding, my question refers to human beings with genetic dwarfis...
Following on from this question. Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process &...
Question Context : Mars second moon Deimos has been converted into a generation ship. A considerable portion of its mass has been shaved off during the process & ejected backwards along its p...
After asking my question about seeing black holes in your path between the stars, I also wondered abut other more mundane objects. Black holes affect large areas of space so even if you didn't get...
I have a world that isn't an exact analogue to medieval technology, closer to the late 1700s in terms of culture and agriculture/metallurgy, only without gunpowder. I have them ahead of real histor...
In my story, I need a spaceplane, that is, a shuttle which can fly in an atmosphere as well as in space. It needs to be able to land from space, and then take off and go to space without refuelling...
Imagine a species one foot tall that has a relatively large brain for its size. The species has human like intelligence and in principle the ability to build anything that we could. It lives on a w...
What would be an efficient method of global travel that can take you from, let's say, London to Hong Kong in about an hour? It would preferably be made quickly, but money is no object. I don't want...
My story is set within one solar system, which can be assumed to have a similar composition to that of our own: one Class G star, a handful of rocky inner planets and a handful of gas giants on the...
A civilization has begun its space program without any knowledge of general or special relativity. How would this affect the program? Would this establish any limits on where/how they could travel?...
For a spacecraft cruising without thrust it is my understanding that the sort of spin gravity utilized in the film 2001, for instance, would actually be debilitating to the crew due to the coriolis...
In the 1960s we were disappointed to find that the moon is a pile of dust and rubble with no easily accessible valuable materials. Well, we kind of knew it before that, but we weren't sure. Anyway,...
Assume that you have a Rogue Planet hurtling through deep space. Somehow, an alien civilization from, say, 1,000 ly away acquires astronomical data from this planet. This data is in the form of h...
This question hopes to make a space tug crew's life tolerable. A supply pipeline links two civilizations. Due to the long travel time between the ends, cargo is "thrown" at the other side in unman...
At a constant 1G acceleration it takes a little less than a year to reach near light speed speeds. Time would dilate locally on the ship slowing time for them. Could the time dilation be pushed t...
Let's consider an O'Neill cylinder with a radius of 3.2km and length of 20km. In the classic O'Neill design, we have three large axis-aligned windows in the shell, alternating between purlins of ha...
So, I've heard that while Alcubierre drives might present a semi-plausible way of getting around the light speed limit (if you can get ahold of negative energy), they do so at the expense of creati...
In my novel, the many moons of Jupiter and Saturn have been colonized, but I'm running into some logistical problems - namely, waste disposal. My first instinct was to dump it on-moon; while this ...
What would make a good propulsion source for small engines and manouvering thrusters for spacecraft vehicles on Europa (moon of Jupiter), both for near-surface operations (vacuum) and in caves bene...
Let's say metallic hydrogen becomes an economically viable resource that we are able to either make ourselves or mine from a gas giant, how would we use it as a power source for vehicles both plane...
I am currently building a campaign for DnD. The main plot plays out on an island the heroes are stranded on after their ship goes off track and sinks. They discover that this island is ruled by m...
I'm in the early stages of designing a city, and would like some advice about to structure its roads realistically for transport. The city is circular, with large roads entering the city at north...
Internal mass drivers are a potentially useful space drive, due to the ready availability of reaction mass (you can use anything from spare parts to literal dirt as a propellant, assuming you have ...
In my fictional universe there are two galactic civilizations that have never interacted until recently and thus have developed different cultures, science, etc. From a technological standpoint, o...
I understand that in order to compress and expand spacetime, an Alcubierre drive would require some sort of "exotic matter" with a negative energy density. Is that sort of exotic matter purely hyp...
Animals on planets are so 20th century - let's herd us some space animals! In this story I have the need to move a herd of pesky space animals. They like Suns for their juicy solar energy and hydr...
One way of creating artificial gravity is acceleration- gravity by inertial mass. So in theory, if we would find a way to travel interstellar space by accelerating, reaching near light speed, woul...
For some reason, all the nations in the world have banded together. Their goal? Go to the Moon. Their budget? As much as the planet and humans can throw at it. How fast could we build a reliable a...
I have seen Isaac Arthurs video of O'Neill cylinders and read through many descriptions, but it still is not clear to me how exaclty the two counter-rotating cylinders are placed in regard to anoth...
Pretty much every vehicle ever invented has been used for racing on at some point, so it seems likely that people would want to do the same in space. However in space it doesn't really work the sa...
I want a character to get sucked into what she thinks is an FTL-wormhole-gate. While it turns out that the gate is indeed a traversable wormhole, it does not allow for FTL travel. The gate transpor...
A moon-sized asteroid approaches Earth in the near future, where space tourism has become normal. The Earth has a few satellite structures above Mars conducting research, as well as successful terr...
In a game scenario I am developing, one option for a fleet to infiltrate an enemy is to use ftl to "hard burn" through a black hole's event horizon. Their ftl drives use a "warp bubble" principle t...
I was wondering, if a planet in similar size and mass to earth would have, from its creation, been spinning at this hypothetical planet speed limit (with it somehow staying in once piece) could lif...
How could an organic, plant-like, intelligent organism move around space? Assuming that the body is inside a small meteoroid and that outside of the meteoroid is covered in tessellating leaves to...
If germs from the past was brought to the present/future on a person (or by some other means of transportation) and we have immunity to its descendants, like the modern germs for example, would we ...
In this world, time travel is possible, but the only thing that can be sent back in time are thoughts. From the perspective of your past self, you suddenly one moment realize that you have "memorie...
Assume that an Alcubierre drive is feasible. In fact, assume that one has been built. A superluminal starship can propel itself through space by distorting space in front of it and behind it. Howev...
With all the interest in VASIMR and the idea of getting to Mars in 39 days, the biggest challenge I can see is having a power source that is strong and light enough to make that possible. So I was ...
