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...
An alien race decides to test the hability of humans to survive and engage into space travel, for whatever reason. The planets The aliens prepares a pair of Earth-like planets revolving around a ...
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...
Earth, far future: We built multi generation ship which can get 20 000 people to another solar system in next 20 generations (600 years) For scope of this question assume that ship itself is well ...
I am building a habitable, Earth like planet, but instead of it being in a solar system, it is inside a Nebula. The actual composition of the Nebula is uncertain at this point, but I am considerin...
Because who needs a space craft? Picture this: While performing a routine spacewalk, outside your small, 1- man space pod, a fault in the propulsion system controls causes the pod to explode, laun...
When I asked my previous question about love on multi generation ship, I left blank the where are the people going. Simply because I do not know. Now I am in search of software which would ease s...
The year is 2020, and an organization known as Helios successfully settles a colony of 200 people on the moon. The colony is self sustaining and is mainly a research center, with most of its resid...
I have a large rotating (think wagonwheel) portion of a space-craft that, at the hub, connects to a non-rotating scientific research station. Imagine a football (soccer) field sized research and l...
Guilty pleasure: I just returned from one tinfoil-hat type of internet pages which suggests that we are being visited by Aliens who live on Venus. The fact, that we have only pictures from the grou...
The human race has colonized the solar system with permanent settlements on all of the inner planets and outposts beyond. Vast space stations pepper the voids between orbits and massive mining/ref...
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 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...
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...
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 ...
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?
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 want to get a shuttle from place to place in a reasonable amount of time. Say, 6 to 8 hours maximum, with a short break at the midpoint to turn around. Assuming constant acceleration to midpoin...
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....
Please note for this, assume technology is being used for their creation, not any kind of space major or anything. Edit: Removed the ability to do so within systems without having generators on b...
A really simple question - if you built a space elevator then you continue building past the geostationary point to put tension onto the tether. Now if you keep building out further and further the...
Researching efficient methods of no-FTL methods often turns up engine solutions that are efficient in the sense that they have a higher specific impulse, but most such solutions seem to have a comp...
Assuming fission thrusters as described here: Would a nuclear fission thruster with continuous fuel injection be possible?, and assuming drilling for the planet's molten mettle core as discussed he...
Centuries ago, humanity have been incorporated into an alien hive mind, spread by a bacterial-like infection. The "bacteria" infects the blood and brain and allows the infected to join their minds ...
A class F star (1.4 times the mass of the sun — it has to go supernova) is expanding into the red giant phrase. Its Earth-like planet, with life on it, has slowly been pushed out of orbit as it exp...
This was spawned from this question about Blueshifting (BS) when traveling near the speed of light. I had found this while learning about the other question. @99.99995 percent c And interes...
As far as I understand, when you fuse deuterium (H-2) and tritium (h-3), you get a helium atom and a spare neutron. Basically alpha-rays? Now alpha rays are easily blocked by matter. You can block ...
I envisioned this method of maintaining breathable oxygen. So each ship would have these gardens generating oxygen like the plants on Earth do. How plausible is this and how would it likely work?
Kaylee is a mechanic on a Generational ship. The ship has several means for propulsion and has a plotted course that goes from star to star, molecular cloud to molecular cloud. It has a Bussard Ram...
In the future a major problem arose: a habit spread among the astronauts to make political statements upon landing on a new celestial body, often the statements were unpleasant to their government....
Major Camila de Ocampo, "La Comandante", wakes with a start. As she's been trained to do when coming out of stasis, she flexes each muscle, beginning with her toes until she finally finishes by rai...
I'm writing a very nontechnical science fantasy with a star-ship (literally a giant spacecraft toting around a star) in stable orbit around a black hole. It uses one of the "stellar engines" mentio...
In this setting, humanity has advanced to the technological capability of extra stellar travel via faster-than-light drives. However, due to distances between inhabited areas being extremely large,...
My answer to this question essentially came down to the pilot being in a sphere with anything large jutting out of it. Some of the arguments made against me I feel are true if we assume fights like...
Considering a distant future where mankind has spread and inhabits lots of star systems. Would there be a justification for inter-system trade or exchanges ? FTL travel may be considered, but with ...
Earth is dying. We mis-managed it and brought the whole ecosystem to the edge of total collapse. About 50 years ago, we decided to move humankind to another planet, and now we are almost ready. A ...
A recent question concerning generation ships made me come up with a rather original alternative in my answer. It was pointed out that the concept of embryo space colonization has already been thou...
I have a fictional technology in my world that involves being able to create "tubes of compressed space" -- essentially, you have two stations and a (straight or curved) line of space between them ...
On earth, we use a simple but effective coordinate system which determines position unambiguously on the surface (GPS achieving accuracy within 1 meter, which speaking as an engineer, is a remarkab...
I was wondering what would happen if you attach 2 Huge ion engines(I mean really really really huge) to planet earth. They should be attached on the north and south poles. Are 2 huge ion engines ...
Visiting the Worldbuilding site plays with my creativity and imagination. So I am going to describe the dream I had: I am member of a different (alien) culture, from a different star system. Also,...
The basic question is: When is a location good enough to build a space centre on it? Some info to the function of the space-centre: The space centre has a lot of traffic, also humans. I imagine...
Related to the this question about not going SPLAT. That one was for conventional travel through space at high speeds. Now I want to know about how things would work with an Alcubierre drive. I...
In a future where space travel is common, how would access to space be regulated? From what I know, currently the International Telecommunication Union (ITU) assigns slots for geostationary satell...
