As an ancient organism whom currently occupies a large chunk of a planet beneath the surface, I have a pesky issue with an invasive species. These humans have decided to colonize my home, mistaking...
I'm designing the type of ships an amphibious race could use for long distance travel, like a floating house, following oceanic currents. I imagine it shaped like an iceberg, with more structure be...
I have a terrestrial planet that is similar to Mars in many ways, a desert-like surface, thin atmosphere, and inhospitable to large flora and fauna as we know it. This planet has ceased tectonic ...
I'm thinking up a Mars or Venus type planet where the poles (or one pole) has a forest growing out of it due to a device that is used to make the planet more habitable by creating a oxygen friendly...
The goverment of Africa decided that it would no longer tolerate the diamond mafia, so the corporation of DeBeers was hunted down and disbanded, to put it lightly. Now, all the diamond mines have b...
So my world needs to be destroyed because of a variety of things. New land masses would be created and destroyed and joined till we had a single continent. In the future, people saw the possibili...
Based on this question about an impossible barbell planet, how hot would the bar be if it extended from halfway in the Earth's mantle to an altitude of 2r of Earth's radius? The diameter of the bar...
My fantasy world is slightly larger than earth so that discovery of the continents becomes harder (about 20% surface should do it). But at the same time I want to preserve most aspects to make it l...
When the old mining town was founded, nobody did think of this ever growing into much more than a coal-mining town. The deposits of iron-ore, aside from the already developed peat bog to the nor...
As he neared the outskirts of the city the canyons of multi-storey buildings lined with coffee- and tea-houses gave way to the large squat shapes of factories, storage-halls and other industry. ...
We all at some point in our childhoods thought that the moon is made out of cheese. As such, I thought: under what circumstances can a planetary surface form in such a manner that it is edible (and...
To expand the territory of the EU, one can consider recreating Doggerland by reclaiming the lost land from the sea: Had our ancestors had more technology, they could have dealt with the sea leve...
If humans discovered a diamond exoplanet and then traveled there, how would they set up civilization on a diamond exoplanet? Everything needs a foundation, even on low-gravity planets (below 9.8m/...
This question is pretty straightforward. I would like to build an earth-like world in which humans don't have access to iron, or at least can't mine any prior to full scale industrialization. They ...
I'm relatively new to all this. I'm thinking of studying a little Earth sciences in the hope that it tells me but, up front, I want to know if I'm completely off. I want to know if a world with no ...
I have found this idea on a discussion on /r/worldbuilding. Anyway, the premise is as follows: The planet is earth-like in terms of size and mass. The planet has a very large amount of small, act...
Before picking specs, I need to ensure feasibility. Only one of the planets need be Earth-like; in fact, I would prefer if the other planet were rather small and dead, like a moon. The orbits will ...
I am imagining a planet more or less earth like. I would like it to have only one pole cap, so only the southern hemisphere has a snow-covered continent. The trick is, I don't want it to lie comple...
I was trying to figure out the early geological/biological history of the world I'm creating, and I was wondering about the development of early life. Basically, I've envisioned a world where Eukar...
Question How can Zircon be used to record data for generations of life forms? Requirements Must be able to store the data with little to no loss of it, for a least 541 million years The data in...
So, vaguely, I remember from earth science that when submarine volcanoes erupt they eventually form archipelagos. My question actually has several parts; Starting with the first eruption to bre...
I am trying to think of a natural event that causes very big impact to human lives - massive movements of people, shift of power, etc. This event happens in a medieval period on an earth-like plane...
After getting help from the members of this site with Worldbuilding an Earth-like world around an F-Type Star, I have another question. The Planet's radius is 90% of Earth's. The Planet's rotation ...
Researchers are scratching their heads, and Portland Water Bureau is furious. In Portland, Oregon, a reservoir in one of the City parks has begun spilling out a river of naturally occurring beer/a...
Let's start with a little backstory--our planet underwent an impact-coalescence cycle only once, 4.5 billion years ago, when a Mars-sized object named Theia destroyed the infant Earth in a glancing...
In relation to a recent question of mine, this alternate Earth still has its core consisting of 84% iron, but the other 16% contains the greatest concentrations of all known species of heavy metals...
So, the Mediterranean Empire has succeeded in separating the entire Mediterranean Sea from the rest of the world's oceans. See this question for background and premise. There are now dams making su...
Back home, Earth had gone through an impact-coalesce cycle only once. Since then, its core has been 84% iron, 6% nickel and the rest being labeled by The Encyclopedia of Earth: A Complete Visual ...
In my con-world I went lengths to introduce a plausible lighter-than-air element and did rather large amounts of thinking about landmasses in order to promote the development of airship technology ...
I am currently working on a piece that has a planet (about double the size of Earth). It is worth noting that this is a low density planet. Without any other factors (Earth-like atmosphere, same pr...
What I "want": My fantasy world has lots of volcanos. Deep under the surface there is a root-like form of life predominant. It grows in big bundles and searches for important minerals, gases, flui...
If you had a planet with hostile conditions (25 atm pressure, 400° surface temp) would it be possible that a cave system could exist beneath the surface at a different temperature and pressure, or...
You sure lad? For some of you folks normal beer is already an acquired taste, but this... this beer definitely is. You understand that this stuff is brewed with water from the devil's choke? You...
Look at you all sitting here. Quite some of you have probably never ventured beyond the outskirts of this city, mayhaps not even past the wall? You've spent your whole lives in this place, but w...
So I'm writing a book and need help to better explain this island that sinks, more on that in a moment as I give you the basic build of the planet... First, its a world on a very tilted angle. the...
Assuming the moon is the same size as ours and its core is generating a magnetic field, and the copper deposits are quite large, consisting of a tectonic plate containing huge deposits of native co...
I have a generic Earth like planet, same atmospheric composition, and the same oceanic composition. The crust of this planet is predominantly silicon based but plenty of iron, nickel and copper. ...
Natural gas comes can be found in the underground, but its origin are the organic rests of a long time ago. However, my gas doesn't come from dead trees or anything like that. So what's an alternat...
The dwarves in my world are humans who starting digging caves in the Maumturks and Twelve Bens in Ireland during the Iron Age, and eventually connected the caves via tunnels rather than trudge acro...
On Earth, there are only two different ways to create major volcanoes. One way is subduction. It occurs when older/heavier rock sinks beneath younger/lighter rock. As the rock descends, it lique...
I'm working on a earth-like planet with a much lower sea level (like 3000m so the mid-ocean ridge would form many islands) but is that even possible? Will the emerged ridge make some weird stuff an...
So, I know that there are naturally occurring beaches that are various 'odd' colors like pink, black, green, and orange and I was wondering if the color of this sand would have any effects on the c...
I have a town, the capital of an empire. It covers 560 Hectares. What kind of natural barrier conforms to the following requirements: Is both heavily defensible and does not hinder trade all too...
Can a habitable planet have two separate crusts, both of which can sustain life? I am wondering if through the planet's creation, over time through some form of mantle cooling/erosion combination, ...
The capital of a country is built on a series of stone hills that gradually lead to the ocean. The stone is noted for both the strength of castles made from it and its unique blue-green coloring. T...
I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and less ocean depths. The world orbits a binary star system at a distance of the ...
The Tsingy National Park is popular for its unique karstic plateaus. These karstic plateaus are thousands of large sharp pillars or needles that stretch towards the sky, creating a wide variety of ...
Is it possible that subterranean caves do/have existed on Mars? We know of the past existence of water on Mars. Which region (if any) of Mars would we likely find/expect to find a cave system bel...
Lately, there has been speculation of what would happen if all the untapped oil, by the handwaving powers of the gods of television and money, disappear overnight. It has been explained, in varyin...
I'm building a world which has, apart from the 'usual' stuff, 2 types of stones (haven't really decided on a name yet). Stone A holds some form of energy but when prompted by Stone B it will rele...
