I'm wondering if it is plausible that a large asteroid (interstellar in origin? Or, perhaps launched from the Kuiper Belt by something big with a lot of gravity?) would be able to smash into Luna a...
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....
I need an Earth where the atmosphere has become unbreathable for humans and animals because all plants have died. But everything else should stay pretty much the same. So here are my questions: ...
A ravine the size of the Mediterranean in area and ~15 miles (~ 24 km) deep on average opens up over the course of a few days in the Himalayas. A size comparison of the Mediterranean Sea to the U...
My post-post apocalyptic society (200+ years after the fall) is extremely technologically stratified, with the haves hoarding near-future technology and the have-nots making do with pre-industrial ...
So when I say everything, I mean everything. Humans, animals, plants, fungi, bacteria, all dead. If the bacteria and other detritovores and decomposers can't decompose anything since they themselve...
Imagine that, in the near future, pollution, overpopulation and war leads to a massive extinction where almost all chordates, some invertebrates and many plants are wiped out. Small, resilient plan...
It's been 21 years Ms. Frizzle has been doing her best to educate the masses. Even with all the knowledge available provided on the internet, not only do people not take advantage, they choose to ...
The basis of my story revolves around a single survivor escaping a massive colony ship gone critical above the skies of an alien world. After his escape via escape pod, the ship crashes halfway acr...
Consider a post-Apocalyptic society of collective farmers that has access to a waning supply of modern farm supplies, a small, independent power grid, and a enough knowledge to keep themselves fed ...
So, in a post-apocalyptic setting, when humans have gone extinct and their cities fell into ruin, I was wondering what animals might evolve to conquer the ruins of our cities. Notice: I know that ...
My question involves the earth being blown up using theoretical dark energy. In this scenario, the crust and mantle are destroyed by precisely placed weapons so that all that remains is the core. W...
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...
Say that an apocalyptic even takes place, a genetic disease wiping out most of humanity in a matter of years. So, there are no bombs, nuclear winter, or any sort of event that messes up the environ...
This is another question for a setting I mentioned in previous questions (currency, ammo). The setting is: It's happening in post-apocalyptic SE Europe (Balkans specifically), about 60-80 years fr...
Other than photosynthesis being an issue, if the Earth's surface became inhospitable and humans were forced to live underground, what biological changes would they be expected to go through to adap...
So the Human World has fallen apart: the grid is down, governments have imploded, the economy is in shambles, people have died in the billions, global warming has made severe weather (much more) co...
The situation is the usual, we have lots of junk metal lying around in cities, great but not impossible difficulties with logistics (meaning that a few railroads are in operation at immense cost, b...
If a hostile group wanted to render Earth or an Earth-like planet completely unfit for human life, what could they do to go about achieving that end? By uninhabitable, I mean a planet on which hum...
BACKGROUND A corruption has seized hold of the land, turning great swathes of it into a poisonous waste that humans may only enter at their peril. Perhaps all who enter the waste grow sick or go m...
So, I the question of what if a black hole hits the earth has been asked to death by various people, but what if the somewhat tamer wormhole hits the Earth? In particular, we'll say that one mouth...
The year is 2089. The political shenanigans of the day have gotten more out of hand than usual and violent zealots have detonated the Earth's largest deposit of plotium devicide, an extremely versa...
So as the title describes, I need an apocalyptic event which is survivable by cryogenically preserved humans in hermetically sealed bunkers underground (or somewhere else). This event should wipe o...
Suppose we have a world that saw a sudden collapse of civilization, not so violent that humans are suddenly struggling to survive but severe enough to cause humans to revert to a mix of city-state,...
...no, I mean, supposedly, I believe there is more about it than mere kans on our part. Installations like this one are found all along the spoorwegs, and yes, around some you should tread light...
Many worlds have an apocalyptic/cataclysmic event. If mine is a Great Flood, how long would it take for much of the world to be habitable land again? Keep in mind, by the events of the present, the...
I am envisioning an apocalypse scenario where a majority of vehicles and electronics are disabled and a vast majority of Grid infrastructure is destroyed. The Carrington Event in the 1800s produced...
I am trying to design my main character in my post-apocalyptic series to have a very dense, organic, durable skeleton. The skeleton should also be able to handle gun fire, a sledge hammer impact, a...
Okay so the story takes place up in the northern hemisphere around glaciers and polar bears and all that good stuff, its main character is named Xavior and he is a good human adapted to the radioac...
I'm very interested in a post-eruption setting in the continental United States. Unfortunately, it looks quite unlikely that a serious caldera-forming eruption is in our near future. However, we'r...
EDIT: Yup, totally misguided here: http://www.physlink.com/Education/AskExperts/ae429.cfm Drifting away. So, no lunar catastrophe for me (without some other handwavium) I've read somewhere tha...
First of all, I'd like to make a disclaimer, and that is that I'm in a brainstorming phase as of now so this question will be generally vague. This also means that any ideas you're willing to propo...
Assume Earth of today was altered overnight. Some percentage of the more common elements of Earth's bulk (silicon, iron, and so on) are replaced with something much heavier. This changes the ov...
The current topic challenge is apocalypse, so I figured I might as well come up with a question about surviving one. A man named Noah somehow learns that there will be a large flood within one yea...
I'm imagining a universe where interplanetary, but intrasystem, space travel is common (e.g. at a similar level to The Expanse books/TV show) - but not necessarily our local solar system. Perhaps w...
Mankind is adrift. Only few millions of people survived, they are struggling to stay alive. Food is hard to find and plants do not grow (mostly). Water cannot be found on surface, the only way to ...
In my particular Earth, much has remained after the human-killing virus, and nature is thriving - even taking over the cities. It's beautiful. But I have separated the healthy populace in orbit u...
Post apocalypse. What resources will be most abundant or useful if mined from Twentieth Century landfills. Easy things like steel and aluminium are obvious, but what else is likely to be worth digg...
Post-apocalypse how well would photo-voltaic solar cells hold up? They are solid state so I expect they would do okay for a while, but would they remain functional for 100+ years. I know that du...
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 ...
What's the easiest way for your stereotypical aliens to destroy civilization from orbit? I'm taking "destroy civilization" to mean the destruction of all large-scale forms of governance, but bonus ...
Meet Joe. Joe is generally an average person with one special trait: He loves astronomy and star gazing. However, Joe has a great paying job as a web developer. He earns 120 000 USD yearly and has...
I'm trying to build a setting in which humankind would have no other choice than to live underwater to survive. Suppose there was a nuclear war in which a huge part of the human population died, ...
This world takes place in the remains of the Eastern United States, devastated by 3000 years of neglect and climate change. The Mississipi river is pretty much a gulf now, which has caused everythi...
The grey goo end-of-the-world scenario in which lots of little microscopic Von Neumann self-replicating machines basically eat everything to make more of themselves. Eventually everything is grey ...
I'm looking for a realistic apocalyptic event, which can't be prevented, but can be accidentally predicted long before it actually happens. By the prediction I mean a scientific prediction, of cour...
Could anyone could survive a nuclear war and all that follows? I have read many things saying they would, and read other science-based answers, but they all talked about a nuclear war that was re...
Imagine there are two regions, one of which has a significantly higher level of radiation. Think of Pripyat (higher level of radiation) and its surroundings (lower levels). How can a person withou...
A small manufacturing town serves as a comparison. The worldbuilding significance is for an underground facility with, in addition to a medical center, small-scale chemical production, a machinist ...
Working on a bit of a story that includes the ejection of the planet Jupiter from the solar system rather suddenly with all of the planets staying generally within it. I understand this is complica...
