I'm looking to know about minerals that space miners can extract from other planet surfaces or directly from asteroids. Something that Earth as a planet may need in the future.
I see that asteroid mining had already been extensively discussed in the context of today's technology (Ex. Is Asteroid Harvesting economic?) and the answer is a definitive "No" - it's not economic...
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...
The direction of the force will always be perpendicular to velocity and pointing to the opposite side of the rotation direction. In plain terms, any object traveling in the rotation plane: up (t...
I would like a planet that's a tropical paradise on one side but covered in ice and glaciers on the opposite side, whether it be the Southern-Northern or the Western-Eastern hemisphere. I know it...
Is it possible for a planetary body to have a secondary axis of rotation? For example let's say there's an Earth-like body that is spinning with its North Pole facing the Sun. Imagine that the Nort...
So, my colony mothership crawls along through sub-space at a "slow" ftl as it sends out faster probes ahead of it. Once it has located a cluster (meaning an acceptably dense grouping, not necessari...
I was wondering if a moon Is in the center of two planets If the gravity will rip It In half or If a moon can rotate around both planets or if the moon manipulates the planets rotation
If the polar cap of a tidally locked planet was all ocean, what weather patterns would emerge? The ocean couldn't be half frozen/half boiling, right? I need a weather pattern so the planet isn't ju...
A quite common idea to provide "gravitation" in space stations is to make them rotate, so the centrifugal force gives an effective gravitation. A possible design is a ring-shaped space station. No...
Could I, purely in quantity of material only, build a solid bridge to a star? Ignore anything like strength, relative motions of systems, that is all taken care of, using lalalaicanthearyouium - t...
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 am developing an alien race whose homeworld is a Dyson sphere planetoid (they used collected planetary and asteroid matter to construct a "hollow planet" around their sun, along with "night" sola...
In my world, humans live on a moon of a gas giant that has extreme weather conditions. They also: have crystals that can store energy. possess the ability to make floating islands (on which they...
In a close future (in 100-200 years), humanity is in an energy/resource crisis and seeks new resources in the solar system. In my story, humanity, still in need after colonizing the moon, sends a m...
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...
Y'all should know by now that I want to build a Death Star ;-) Let's assume that we did that already -- and against the odds, we've built two of them, and they're currently in orbit around a plane...
According to a recent National Geographic article, astronauts returning home after longer missions suffer permanently impaired vision. This is a problem that must be addressed in hard-science world...
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 my world, ten is an important number that shows up frequently. In the solar system my world belongs to, there are ten other planets beside it, and there are ten months in a year. I know next t...
The Question about the blockade of en entire star system makes me wonder: How would, if possible, a space "radar" work? Or how would you scan for Ships further away than your Optical sensors can ...
Many science fiction stories, movies, and shows involve characters undergoing explosive decompression, the technical term for a rapid drop in pressure, usually all the way to a vacuum. Frequently,...
My planet orbits two suns. The orbit of the first sun is similar to Earths orbit around our sun. The orbit around the second sun however makes it appears only around the horizon. Is this possible?
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...
Let's say that space around earth has no debris. Super elevator is some super durable cable between a space station and earth by which some elevator can travel. Space station is in geostationary or...
Let's say that I start with a Stanford Torus that can house some amount of people. Over time, more and more people start living there, to the point it starts getting crowded. How could I expand the...
Boules is a range of relative games played with small, heavy steel balls thrown on a court, such as the French Petanque and Italian Bocce. While there is variation between games in terms of how an...
I'm writing a murder mystery set on an interstellar starship. Context: The victim was found dead in a zero-gee chamber inside the ship. The ship is in interstellar space and traveling at around h...
I am working on a space game that allows players to participate in the human colonization of a distant star cluster. I could use some help determining what sort of numbers I should have aboard the...
I'm writing a book that involves having a space station that acts as a way point between Earth and a new planet. (Hard"ish" SF, or as "Hard" as I can make it...) The Station sits at the mouth of a...
If an advanced race builds a Dyson Swarm comprised of millions of habitats and billions of solar collectors orbiting a star, and then are completely and inexplicably all killed with minimal damage ...
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...
I'm building the world of my story for my comics and I've come to a bit of a standstill with a particular idea. Assuming there were no other planets in our universe, just a single planet Earth. ...
Say you've got a space-faring civilization that needs a LOT of power. Sure, fusion is a thing, but there's really not that much helium-3 to be found in our solar system, and it's hard to get. So ...
So I have been doing a lot of reading on space elevators/tethers for a SciFi book I am writing and unfortunately there doesn't seem to be a whole lot of info on building one on Mars rather than Ear...
The year: Sometime a long time from now The place: Mars Little Bobby Colonist is going to play out in sand dunes beyond the edge of the domed city where he lives. Terraforming efforts over the la...
If a planet had such a large imbalance of protons and electrons that it possessed a net negative or positive charge what would happen to it and its solar system? First, could it be stable, or woul...
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...
I know that currently, black hole civilizations are only theoretical. But here are my thoughts on why black hole civilizations are impossible. Black Hole Civilization Issues 1. Gravity This is...
I have a world where there are two types of beings. One type, let's call them X, exist in our "dimension," and the other, let's call them Y, exist in another "phase" or dimension. Only 10% of X b...
I have a story idea that involves a human attempt to halt and reverse global climate change. The idea is a simple one - a satellite that partially blocks out the sun. The satellite is located at th...
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 ...
I am looking for a (if only semi or even the tiniest bit) scientifically explainable way to make a spaceship travel fast enough that interplanetary travel (take the average distance between any 2 o...
In the climactic final battle Faction A engages Faction B on Faction B's planetary base, both in orbital and ground combat. Realizing they can't win, Faction A activates a device that transports an...
Taking into account all of the developments in the alcubierre warp drive theory including the new calculations by Harold White. Are their any plausible/theoretical ways to generate a warp bubble wi...
Background: In the year 2204, humans have colonized most of the inner solar system. During the first explorations of the vast outer system, a team of researchers uncovers a series of alien artifact...
The Apollo-era A7L Extravehicular Mobility Units were used for less than eight hours at a time, within a few days, with a maximum of three moonwalks per mission. Assume a fictional moonbase with 1...
I want to find out what's going on in another star system, but I don't want to go there. How feasible is it to just build a big telescope and take a look? Scenario: Earth does not respond to commu...
