Suppose that there are 2 interstellar empires at war with one another, both armed with FTL drives which cannot be used within a certain radius of huge gravity fields, stars, gas giants, etc. Anothe...
For a science fiction novel I'm currently writing... The spacecraft in question is based in the asteroid belt and is not designed to approach a planet. The ship has an offensive/defensive capabil...
All of the launched human habitable space stations in orbit around Earth (such as the International Space Station, are very spindly and brittle as of current day. In a idea I'm contemplating that ...
In my answer to my own question, Physical laws for a matter-filled universe, I detail the gross physical laws that would shape my four-spatial-dimensional matter filled universe. Given a slowly ex...
In a civilisation similar to humans (although not necessarily humanoid) living on a planet the size of Earth, could the whole civilisation (no limits on size, although I was thinking a few thousand...
In a parallel universe if two objects occupy different positions in space then in the reference frame of each object the other has length contraction and time dilation. If the two objects are very...
Grab the popcorn ladies and gents, I'm gonna talk about a movie real quick. In the movie Total Recall (2012), the main character and his friend step into a huge earth elevator/public transportati...
Inspired by https://worldbuilding.stackexchange.com/a/30400/3434 Related but too different in details for answers to apply Why not build a space elevator starting from the moon? As answered in th...
What immediate effects would a small, short-term black hole have if it appeared in a residential backyard? How small or short-lived would it have to be to be survivable, if it is survivable at all?...
I've built a device, it's capable of turning matter to energy and energy to matter with perfect efficiency, I've got the resources to build a space station in secrecy, and I want to get off the pla...
We have all heard about the idea of space elevators, a cable so long that it literally reaches into outer space, to be used for launching payloads cheaply into Earth and interplanetary orbits. Howe...
What would be required for a generation space ship to give residents the best possible living situation while still using the least amount of space, given the possibilities to have access to common...
Lets say I have a space fleet flying to attack an installation. The enemy knows I'm coming but not my numbers or exact disposition. Since I'm moving much slower then C the light from my fleet wil...
What would be the possible and definite effects of two galaxies colliding with each other? (Milky Way & Andromeda) Long-term and short-term effects are both important. I'd like to know becaus...
So the premise goes: A previously-traversable wormhole evolves into a black hole because (x) happens. What's (x)? What would it take for this to occur? Either naturally (a cosmic occurrence), by ...
Imagine for a few moments that despite the difficulty a race has evolved in space, away from any atmosphere (perhaps a species of space jellyfish). This race exists in a fairly 'noisy' nebula, but...
I know that in our universe, electromagnetism and gravity decrease with the inverse of the distance squared. Would it be possible though for there to be a force in another universe with three spati...
Supposed we have a ship travelling at the speed of light, or very close to it, or over. A second ship is travelling behind it at the same speed. The second ship wishes to communicate something ...
As the legend goes, Coca-Cola was planning on shooting lasers at the moon to project their logo. Unfortunately, the FFA said no (they didn't want planes to be blinded). I haven't been able to confi...
Follow up to my previous question, after botched registration. We have an Earth-like planet tidally locked to a star similar to Sirius A. The star does not belong to a binary system. The planet it...
Here's the setup: You have a space station orbiting Earth. On this space station is an anti-gravity device powerful enough to lift a small ship on Earth up through the atmosphere and into the space...
Researchers create a sonic tractor beam By Hanae Armitage 27 October 2015 1:00 pm Using a simple set of loudspeakers, scientists have figured out a way to levitate and rotate object...
I first was thinking centripetal force on a circular ship, but performing external maintenance would be extremely difficult due to the force pushing the person or robot off. Would a spherical ves...
Can non-intelligent life forms evolve to leave their home planet and travel in interplanetary space, for instance, grow on atmosphereless icy moons and transfere spores over interplanetary space?
Set in the 22nd century CE, space explorations reached maturity and the farthest human colony is on one of the moon of Neptune. So far the only voice from space that we have heard comes is our own,...
Most parts of the observable universe are generally extremely cold and has no air. So if some organism can survive naturally in space, and thrive near 3 Kelvin temperatures without any form of air,...
Question is ultimately asking why would we do this? A few parameters first... Technological: Our current knowledge of physics is correct and there is no such thing as faster than light travel, ...
I am a staunch believer that any near-future permanent colony on the Moon or Mars should be built underground, at least the living spaces, due to the harmful effects of radiation. What is the grad...
Lets say you have a small group of space colonists. They were screened for sickness, viral and bacterial, as thoroughly as we knew how before being sent off to the colony and all were found health...
I am wondering what are some of the major concerns/designs an intelligent flying species would have in designing a starship? Generally we consider space to be a premium and crew living space is al...
Follow up to this question: How would earth goverments respond to killing of most of a colony to keep the rest alive long enough for rescue but with a different approach. The same scenario occurs....
Assume someone detonates a Hiroshima-sized nuclear bomb in space. Since in space there's no air, the bomb will behave differently than on Earth. In particular, there will not be an air pressure wav...
Ok, so the Earth is filling up, finite resources, and as we all know, there are no plans for us to reduce our resource hungry ways,...and Mars has no magnetosphere apparently which means we couldn'...
Think about a big space station or whatever giant space building. What will be its mass to attract (with gravity): Small asteroids (1-10 kg / 2-20 lbs) Spaceman (100 kg / 220 lbs) Satellites (...
Okay, so some space miners fly into space to get Helium-3, and then fly it back to earth to sell to non-space people. Flying into and off the earth is rather expensive, so they want to simply take ...
Some answers to this question about mining asteroids suggest that it is easier and cheaper, in the long run, to bring the asteroid to you: move it into orbit around the planet where you are already...
I asked a similar question (in a SpaceEx manner) on Space Exploration, but here I've made it a bit more ... worldbuilding. We have a nice Space Elevator, and I'm in charge of the luxury guest acco...
Let's assume that there is a way to travel into space that's not in a rocket, and a human can essentially just walk/be carried into the upper atmosphere and beyond. Would there be anything that, p...
Most interested in effects during the first <75 years. Things to consider: What type of organization is building the space elevator? How is the service sold/rented? What is its maintenance/s...
At a crucial point in the development of human civilization, there is a split in the timeline: one where FTL travel is facilitated by jump-drives/wormholes, and another with superluminal speeds (St...
The idea is- as the moon is passing over, the pull of Earth's gravity on immediate area surrounding the spacecraft somehow temporarily cancelled out (still working on the how) and the craft falls t...
We like the moon. It's close, you can see your home from there, low gravity well, so you get easy mass drivers to orbit for fleshing out your spacer economy, plus you can do fun things in pools. ...
Okay, so humans are finally transitioning to a space-colonial society. We sent ships out, colonize worlds, etc... We aren't really in the business of sending multigenerational ships. Instead we use...
I have got a big rotating space station (radius is 5 km and length is 30 km) which provides its occupants the luxury of full terran gravity and atmosphere. The biggest part of the cylinder's inner ...
Suppose a planet/space station is a hollow sphere, and in the center of this sphere is a smaller sphere. This sphere would be solid, with grass and dirt like Earth. The only thing holding this smal...
An ancient civilization mapped wormholes when the universe was quite young and smaller. This allowed them to reach other galaxies (wormholes from our galaxy to others). They mapped it all. Humans ...
Lets pretend that Mars was a bit larger, so the gravity could hold on to the water and possible atmosphere, and then play along with the accidents that happened on earth happened at a similar tact....
Let's suppose we have found a new human colony today, somehow populating Pluto. They have good technology, much like ours and we don't want to slave them. We want to establish a communication link ...
Our main character Felixa (female, weight about 70kg) is onboard the ISS (altitude 408 km / 254 miles), when something similar to Gravity happens, and the space station is destroyed. Her assets: ...
The government of Futurestan has finally decided to hear the voice of her people. It would seem that the protriotors access to malware, EMP-otovs, and weaponized angry glaring (and thermite. Lots o...
