So I'm creating a world where the ground is mainly made of different rocks and stone in most areas - soil is sparse. Could trees and plant life grow on the stone ground if a water source is nearby...
My ancient golden dragon has a lot of time, since he doesn't die of old age in my world, and a lot of magical constructs that will tirelessly built a defensive mountain chain for him. This chain w...
While by no means a smoking gun, there is still a reasonable amount of empirical evidence on the notion that socialization and testosterone are negatively correlated. Archaeological Evidence Fro...
I've got an intelligent humanoid species living on a planet very similar to Earth's. However, on this planet, rainstorms are more frequent and slightly... different. Each raindrop is at least an in...
Sometimes old, discredited or impractical ideas come back to favor, because a new technology has evolved. Let us imagine a future Earth-like world (not early 20th century or steampunk) that would ...
The hypothetical world is for all intents and purposes earth or very close to it. So what would the effects be if the magnetic field were either stronger from the start of the planet, or if the ma...
As the title says. I need to have at least 3-5 habitable Earth-gravity worlds (preferably with atmosphere, nitrogen oxygen) as many smaller, lifeless moons as possible, and a planetary ring. (i.e. ...
For one of my projects, I'm developing an inhabited Earth-like world, with the key visual difference being that much of the land is purple, instead of the brownish colour it is on Earth. My questio...
I've been working on a constructed world which started out as the home of an alien race from a sci-fi story I'm writing but just became a pure world building project. As you can see from the map i...
The Great Red Spot on Jupiter and the numerous Great White Spots on Saturn are storm systems that encircle the globes and last for decades, centuries in Jupiter's case. These are formed on Gas Gian...
I've looked for an answer for this, but the only information I could find dealt with the ring itself. All I want to know is what would change on the Earth if all problems were solved and the ring w...
Premise Inhabiting my earth-like world will be humanoid beings that have a skin tone that is as dark as Vantablack. Let's assume these human-like beings share the same ancestry as humans and we ca...
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...
The setting On an Earth-like planet but with completely different flora and fauna there is the Great Plain. It is similar in size to the Serengeti National Park on Earth. The Plain is surrounded b...
Another question based off of this one here. Let's say on a cube styled Earth-like planet, there was a similar race to humans. If the differences in the planets were minimal (besides, you know, the...
We have a fleet of sub-light speed generation ships and associated engineering devices/ships. Their original world can no longer support their species, and they must move to survive. The fleet of c...
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 ...
Earthlings, I live on a world where most places on my planet has four seasons, just like yours does. We also have one sun and one moon, presumably. It's been not even a year since I came of age (2...
I'm working on a story set in an Earth-like world but with rings (say, proportionately similar to Saturn's). I'm trying to get a solid handle on how these rings would affect the sky. For the purp...
Is it necessarily a given that a compass (as they magnetically function on Earth) could be made to function similarly on an alternate, Earth-like, ringed planet? Another way of asking: is it feasi...
I just wanna ask which option requires more destructive energy? Option 1 : destroying a planet like earth to rubble (tiny pieces of rocks) Or Option 2: splitting a planet like earth in halves ...
I'm the city designer for a new city we're calling Morrowville. Having some of the worlds top minds, flying cars have been invented, but can only fly a few feet (2-4) from the ground and not everyo...
Scientists have discovered an Earth-like planet in another solar system, with the same gravity, atmosphere composition, etc, and they decide to colonize it. There is only one problem, though. It is...
I'm creating a sci-fi world similar to ours roughly 50 years in the future. Unobtanium, a futuristic metal and fuel source, was discovered in 2020. Its broad utility led to rapid advances across al...
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...
Imagine a small primitive humanoid civilization that developed independently in caves under the surface of Ganymede. We can assume there's enough light that filters through the crystalline surface ...
In the world of this question, ants and especially termites are the dominant herbivores by mass. There are no large grazing mammals competing with the bugs for the siliceous grasses and thorny tree...
I have the radius, volume, mass and density figured out. It does not have a moon. I do wonder how that will affect the rotation. The Earth's rotation was considerably faster before the creation of ...
I recently asked this question about what would happen if a fusion bomb went off in the core of a planet, and the answer was relatively uninteresting. As was aptly said in my previous answer, the e...
Please note that I have had some incredibly helpful and useful suggestions here that I have decided to make some major revisions as a result. I will reduce the overall atmospheric pressure and part...
Ok, so I have determined my world can keep it's planetary ring system. YAY! Now I just need to clarify once and for how it would look like from the planet surface. I think I have it worked out, but...
I'm an artist and I've been trying to find a comprehensive resource that would help me clearly identify likely sky colors for exoplanets that have atmospheres with a similar chemical composition to...
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 ...
We have an Earth-like planet except the tropics around the entire planet are covered with small island chains and archipelagos. No landmasses larger than Cuba appear between 35$^\circ$ N and 35$^\c...
Setting In a tropical shore, where a great river empties into the sea, there is a zone of very high tides. The water level rises and falls by meters every day. In this challenging ecosystem, alter...
Imagine an Earth-like world in all respects except that the Moon is much much closer. I think I'm right to say if the Moon were very close that tidal forces would slowly rob it of momentum and it ...
The Bay of Fundy sees the world's highest tides, with ocean water advancing and withdrawing as much as 20 meters or more within a single day. Here is a list of the 50 tidal stations around the wo...
In my world there are two planets within the same solar system, which are connected approximately every seven cycles through a portal that opens for a few days. The planets are very similar. The ...
What kind of realistic oxygen producing reaction used by life could exist in a carbon dioxide / ammonia atmosphere? There are also many volcanoes, either immersed or not, water oceans and you can e...
I have a world I am building that is similar to ours, and is set in the height of the Roman empire era. The main difference is that the winter is half the year and full rotation of seasons is 18 m...
This blog post about binary-star systems points out that, rather having the stars be close together, they could be far apart and a planet might orbit just one of them. It gives the example of the ...
I'm currently writing about an Earth sized planet that is 33% water and has 4 moons all the same size as our moon. All moons are 243,000 miles from the planet's surface and the planet takes 392 day...
My species of caniform-like creature has a relatively long muzzle because of its strong sense of smell. I would like to know how to give it a long muzzle with its large brain size. Members of this ...
Recent news reported the discovery of three "earth-like" planets in the TRAPPIST-1 system. This is interesting because the star is a small, cool red dwarf about the size of Jupiter. The three pla...
Background There is a world with flora and fauna based on the life forms that evolved on Gondwana (see here for previous questions). Humans colonized this continent from a distant one some thousan...
I have a huge planet with two continents separated by a wide ocean. Inhabitants think that their continent is the whole world because the other side is too far and they never visited it. What if pe...
Premise Suppose a world has no other means to deal with a potentially devastating meteor impact than creating a net on the planet. Their hope is that the massive net will catch the meteor and slow...
The Earth-like planet I'm working on is the culmination of years of labor by the galaxy's best scientists. It consists of fully artificial ecosystems, and is, for all intents and purposes, like Ear...
Premise I am in the formation phase of a fictional world. I would like one of its notable characteristics to be extremely large waves. On Earth, most of our large waves are triggered by earthquake...
Back home, Venus is a twin planet with serious issues. The average surface temperature is 900 degrees Fahrenheit, atmospheric pressure is 92 times greater than ours and carbon dioxide makes up 96%...
