In its heyday Earth was a great interplanetary trading post on account of its low gravity moon which was used as a warehouse for all kinds of goods. The Moon was covered almost entirely in large w...
In my book series, a group of a few hundred explorers are sent from a planet called Ishgabangaloodoo to explore Sea World. Some things to know about Ishgabangaloodoo: Its citizens are referred t...
I saw this a while ago, and it has bothered me ever since. Imagine a world where you know everyone is going to go crazy in exactly one day. The entire world's population will try to find and kill ...
Imagine we took earth and slowed it down so that a day lasted 100 years, could humans (or any life) survive? Let's assume that there are no ill effects of slowing it down, no massive tidal waves, n...
In my world, 3-inch humans live on an Earth-like planet. My question, provided by a comment on a previous question, is: What would an anatomically correct 3-inch human look like? How strong would ...
In the near future we may find cargo ships fleeing space pirates! Given that... It's a small cargo ship carrying 10 metric tons of wheat (cargo volume, approximately 13 m3). Total volume: 100 m...
Imagine that all men in the world became infertile right now. (This would apply also to all new born boys for as long as no cure was found.) How much time would humanity have to find a cure (or li...
In the short story, a man is swallowed by a giant, fictional fish. In fact, he is swallowed whole along with his log cabin and a bunch of hand-crafted tools. In a "The Martian"-like narrative, he m...
Assuming that there is a prison somewhat akin to the one in The Dark Knight Rises, except being nothing more than a cylindrical hole in the earth, how deep would it have to be to make escape attemp...
Okay, following my previous core question, after the apocalypse, one of my sets of survivors in this setting, the Usnay, managed to live in a fleet of ships for over a thousand years. This is pro...
Can humans survive by eating only nails and hairs of their own? As they grow they consume their own hair and nails. Hair includes even body hair. What is the maximum number days a human can surviv...
So, on the planet Aqautas, the Aquata species is the apex species. They have cities underwater, made of an alien coral, and submarines to get around the planet. Crime is also an issue however. The ...
So, out in Colorado, in the city of Den (population 1600), there is a huge problem. Before the war, a geneticist lab was trying to create police dogs that were stronger and superior to normal dogs....
Background story: Current Earth, in the close future. Astronomers have found first signs of extraterrestrial life: huge sheet-like objects (with surfaces easily as large as the surface of the Eart...
EDIT: Since many people think this question is unclear, let me rephrase it: Can a species with only specialists survive unassisted for a long period of time? Specific applications: A Robot group...
In the future, space travel is common, so common, in fact, that commercial transport is available to most people, like air travel is to us. As a passenger on a vessel of Galactic Spacelines, half ...
First, yes I was inspired by this question: "How do you check if a room behind a door aboard a spaceship has an atmosphere/pressure?" I wanted to take the scenario further, instead of asking how t...
I asked a similar question earlier: What would happen if electricity stopped working?. But I was also thinking about what would happen if magnets stopped working. This question is very related to w...
Planet: Xibalba (Mayan Hell) Tidally locked planet around a red dwarf that is very active with solar flares being a daily danger. The habitable zone around the planet is made up almost entirely ...
An interstellar spaceship carrying a thousand personnel was attacked by a group of space pirates while crossing the nebula. The nearest habitable planet is several light-hours away. Help will onl...
I was wondering if a creature could use natural armor plating to protect itself from radiation. For some numbers, I would like the creature to survive normally very lethal radiation, 30 Grays, for ...
What would be the design of a near-future extreme-cold environment suit? Consider a protective suit that is not a space suit because it doesn't need to augment the pressure felt by the body. It d...
I have this planet that's 1.8 times the size of Earth on an eccentric orbit around a star that's 0.2 times the size of the sun. Its apses often change due to the influence of a neighboring gas gia...
I have read questions such as these two about aliens adapted to environments with high atmospheric pressure experiencing negative effects when exposed to Earth's comparatively low atmospheric press...
I'm working on a post-apocalyptic desert scenario in the near future where people live in small, loosely connected communities that trade with each other on a small scale and might have agreements ...
In a "mountains and valleys" type area, there is a very large fire (say, an acre or two) that generates a lot of smoke. Where would the wind be strong enough and constant enough in this type of ge...
So, a little bit of pseudo backstory first. Imagine mother nature would be some godly being, that actually exists. Somewhere. In spiritual form. Now imagine humankind would be a big thorn in her ...
How could humans survive underground for centuries? People have built multiple underground facilities around the world to prepare for a catastrophe. Just to be careful they overcalculated their res...
Okay, I just asked a question, in which mother nature transformed all animals (or brain containing living beings, if that fits better for you) into a being twice as big in order for them to kill of...
I'm writing a medieval/post apocalypse world stricken with horrible dust storms that last days or weeks at a time. Would it be possible, using medieval technology, to: protect yourself from such...
A rocky planet, similar to Earth in mass and composition, is set to pass through the solar system in one year's time. It has frozen oceans of water ice and a thin atmosphere of unknown composition....
Alright, so I've been doing some research on hypercanes, which are, in short, theoretical hurricanes that may have ravaged Earth in its ancient past, when ocean temperatures were much higher (at le...
I plan on writing a story about a human born in the wild and raised by wild animals. I have heard of stories of real humans being raised by wild animals, mostly in Africa. I have also done some res...
Consider a world where the majority of creatures behave with might-makes-right rules. How could a pacifist race adapt its biological defenses or its society over years of evolution to protect thems...
I asked a similar question a small while ago. Unfortunately, the way the problem was defined excluded certain viable solutions. So I want to try again. The society would have to be complex. Perhap...
This is one of a series of questions centered around how an isolated group of people would survive. Each question focuses on a single aspect of survival. Details about the peoples' situation are be...
The village background: It is located at an elevation of 2,119 m (about 6,952 feet) above sea level with a population of about 1,800. It has a continental climate with Oceanic influence. Summers ...
The scenario is the following: a civilization with technology level similar to humanity's current, on a planet similar to Earth, shall be hit by a massive celestial body in approximately one year. ...
The year is 2109 C.E my friends and I were caught in a space disaster when the spacecraft we're in broke apart during a daring escape from a patrolling spacecraft. We stole an antique cellphone (fr...
Set in the year 2216 C.E. Imagine a spacecraft with a crew of twenty is leaving for Enceladus, moon of Saturn which is estimated 1.272 billions km away in a matter of months using the next generat...
Short version: 1 million people were left to fend for themselves (a.k.a. there's no room at the inn scenario) through what amounts to a storm of asteroid fragments pulverizing the United States (l...
I have seen some questions asking whether some atmospheric compositions are survivable for humans. Most of them focus on long term survival, as in people being able to breathe indefinitely without ...
Let's assume this planet has had a normal lifecycle up to this point, becoming an Earth-like world with around the same climates, size, landmass, day/night cycle, and has a single moon of similar s...
Assume that the atmospheric concentration is still the same 78.09% nitrogen, 20.95% oxygen etc, except now just as dense as the Venusian atmosphere. Would humans be able to survive in this atmosphe...
This actually occurred in a dream last night, but I'm interested in what could come out of this. I'm not experienced with writing stories and have only read some Worldbuilding posts, so excuse me i...
In this case the person would experience 292Gs by the end of the 14 months, which should be enough to kill him/her but, considering that it would have taken 14 months for the environment to reach a...
The world is divided in several factions. Among them : Insects and Humans. When I say Insects, I don't mean insects : insects are the little creatures with six legs while Insects regroup all soci...
There is an emergency on board the ISS. Astronauts can´t evacuate and they will die within five days if critical repairs are not made. Fortunately an automated cargo spacecraft, like Cygnuss or P...
I need a meteor to deliver an extraterrestrial algae-like cellular life form to an urban environment/city. The meteor needs to be far enough that it will not impact the Earth and will not cause ...
Specifically trying to create an alien species that can survive most environmental stressors and find a way to create an environment that justifies the species developing its characteristics that a...
