The boom-bust cycle answer I took for my question: Sustainability of Regular Global Wildfires due to Oxygen Rich Atmosphere pends on the atmosphere being rich in oxygen but poor in CO2. I, however,...
Say humans found a way to exponentially increase the capability of plants to grow. Is it possible for it to cause an environment that can cause oxygen toxicity in humans?
My non-magic fantasy world has a species of hominid that lives in a huge and wide sierra of mountains. If they had split off from the (now dominant) human species a couple million years ago, (say a...
In my story Giants, humans, and a bunch of other fantasy races live along side each other and i'm curious as to what sort of environment (on earth) would best suit them? some basic characteristics ...
I recently started to wonder what a tree would be like on an alien world, and one thing that popped in mind for these trees was their color. The hosts star and environment would have a effect on sa...
In a setting where an empire establishes an island colony far to the north, what is the coldest climate such a colony could sustainably survive were that empire to collapse and stop sending supply ...
In my book series, I'm worldbuilding a planet whose culture is based on Celtic mythology and history, and in order to be consistent with real life I feel like the whole planet's environment needs t...
Earth sized planet in the goldilocks zone. Similar mineral composition and surface water. Photosynthetic life evolves and thrives on land and sea. Atmosphere and climate comparable to the beginnin...
Back home, five million years ago, the warm, wet climate of the Miocene sloped downwards into the cooler, drier Pliocene before descending even further into the more so Pleistocene. The slope was ...
Genetic chimerism is a condition in which a single organism is composed of cells with more than one distinct genotype. In animals, this means an individual derived from two or more zygotes, which c...
In my story Orcs, humans, and a bunch of other fantasy races live along side each other and i'm curious as to what sort of environment (on earth) would best suit them? so basic characteristics of m...
A long time ago, the 60 foot long Megalodon roamed the oceans. Fast forward to 2.6 million years ago and they went extinct. In the story I'm writing Megalodon hasn't gone extinct surviving at least...
A magical calamity has wiped out an area about twice as big as Germany. The calamity also altered the climate in the region from one supporting forests and grasslands to a desert similar to the Am...
Background A large star makes a relatively close approach to a solar system like our own and the orbits of many of the planets are badly perturbed. A planet similar to Earth is in the wrong place a...
Let's assume a world where humanity managed to stabilize the climate again and maybe even reversed the effects of the current climate change. (So that we can ignore the current global warming in th...
I'm interested about whether or not and how gravity would be affected on deformed planets. You could think of this as whether or not mega-asteroids would be able to sustain life? If so, would diffe...
Would it be possible to "green" the Saharan desert, given near future technology If so what things might have to be done, what kind of plants or bio engineered plants and animals would be introduce...
In my world they live in a swamp similar to the Okeefenokee swamp in Georgia. My question is, would it be possible to farm certain plants like wild rice, milkweed, and lilypads in these conditions?...
From 2.4 to either 2.1 or two billion years ago, Earth underwent a surge in a waste product that we know as "oxygen". Before that, life thrived in an ocean rich with iron under an atmosphere loade...
I want to create a world where humans can live outside (perhaps with some protective clothing) but where very high winds exist in almost all potentially habitable areas making life outside impossib...
In my military sci fi story in which a squad of private contractors have to contend with hostile creatures reliant on scent and mechanoreception to hunt, I wanted to keep the sci-fi 'hard' and plau...
So imagine people were the size of house cats, and the world's land masses were scaled down accordingly (in volume). In comparison to the original size of the landmass, how big would England be? An...
Hello there, it's my first time posting, so I'm sorry if I'm going against formatting. I'm making a continent for a fantasy setting, and have been firstly focusing on geography. This continent s...
I am working on a story about a person who was raised on an earth-like planet and later moves to our earth. The planet he is from specializes in fruit juice and alcohol making, in specific, wine. W...
The Orion's Arm Universe Project includes a description of what they call "To'ul'hian Worlds", planets that are (in the simplest of terms) a cross between Earth and Venus. I'm working on designing...
I want to create a tidally locked world with a habitable (broadly Earth like atmosphere and biome that humans could breathe and live in) band stretching around the terminator pole to pole. There wo...
I want to use the an active large ignious province (LIP) as a "biome" on a continent in my world. This video about the Siberian Traps inspired me. A LIP modeled after the Siberian Traps gives you a...
Question: Are there are any serious biological or evolutionary plausibility issues with separating the energy storage/production function from the production of structural/regulatory biomass? Back...
Assumptions: Jupiter's moon Europa has a salty subsurface ocean in contact with a rocky mantle. The ocean is populated by hydrothermal vents produced by tidal heating. Global heat flow is similar...
I'm imagining a hypothetical scenario based on the Big Rip theory of the end of the universe (https://en.wikipedia.org/wiki/Big_Rip), where eventually the expansion of the universe causes everythin...
What I'm looking at doing is a small game where you land on a planet, and the atmosphere is not survivable by a human being, but there is local life. Over the course of the game, terraforming has t...
Assume I have a human colony on The Moon. A meteor fragment gets by the defense system and smashes into a portion of the dome, let's say the hole is 1 meter in diameter, it's big. Safety measures...
So, the X-Seed 4000 (https://en.wikipedia.org/wiki/X-Seed_4000) is a rather large lad. The tallest building ever fully realized. Let's just say that, in five decades, they decide to actually build ...
In the game Monster Hunter World, there is a place called the coral highlands. The coral highlands is one of the most spectacular things to look at in the game, having a resemblance to a ocean with...
I recently asked a question about' "The feasibility of the coral highlands", which come from a game called "Monster Hunter World". In the game, there is another place, called, "The Rotten Vale", wh...
The planet has 256 days in a year, split up into eight months, each with 32 days. My planet is a bit smaller than Earth: Think, enough space for the continents of Earth's western hemisphere and th...
Humans (even programmers :-) ) are used to having some access to natural light, but in a colony in space, on the dark side of a tidally-locked planet, or underground (for example) this won't happen...
The planet needs to be able to support life but initially ve devoid of it. Which I would think would make it's Soil like that of a desert. The regolith may be important for early agriculture. It ca...
I had an idea for a new world that included cactus forests, with cactuses the size of a giant sequoia. Is this realistic?
I'm getting into mapmaking, which I enjoy, but some of the specifics of realism still elude me. I know generally how plate tectonics work, but I was hoping to get some help on a specific example. I...
I know that red dwarf stars are dimmer than ours. But I also know that red dwarf stars emit a lot of infrared light, so creatures on a world orbiting it would have eyes that see infrared light. I...
What is the cheapest material per ton that one could purchase on our Earth in the 21st century? This could also include the cheapest material per ton to harvest so dirt may seem like the obvious an...
Is it possible in 21st century Earth for someone to create a small super insulated box to store heat like an "anti-freezer" such as putting lava inside the box and the box not being hot to the touc...
On Earth, while birds and reptiles can be quite brightly colored, it's rare for mammals to have any bright colors, and the rare times they do, it's either just slightly different (like with orangut...
Let's say we have a species of plant, that, for whatever reason, only wants to be pollenated by female pollinators. Maybe this gives some advantage to the plant and/or pollinator. Why would a plan...
We have a question that covers what would happen if the world didn't have any wind. What I want to know is how we would get there in the first place. Given that we aren't using any magic, what woul...
Here on earth, it takes about 90,000 years for major ice sheets to build up, and another 10,000 for them to collapse, resulting in 100,000 year cycles of major glaciation, from what I understand. ...
Setup: Earth developed in an alternate universe with small oceans and little water. A little before animals first left the oceans and began to walk on land, when all of Earth's land was barren sand...
I know that gas giants are much larger than terrestrial planets, but wouldn't several million or billion years allow for it to gain mass from collecting space debris and the like?
I'm in the process of naming some routes and roads in my medieval fantasy themed world, and I want to specify routes that could only be managed on foot. I'm tempted to say trails, but since every b...
