I have a roughly Earth-like planet in a solar system some distance from ours. The atmosphere of this planet is largely similar to that of Earth, but particularly, has a somewhat higher oxygen conte...
I was zooming around on Space Engine and came across the moon of a gas giant that was hovering well above the galactic plane. I'm admittedly not well-versed in under what conditions an Earth-like p...
Welcome to planet X! Planet X is the same as Earth in radius, composition, axial tilt and orbits star Y (identical to the Sun). Planet X has a moon known as moon Z (identical to Earth's moon). Cou...
I'm building an earthlike world that has a moon orbiting a gas giant. Is it possible for the moon to always be between the planet and the sun? Also, is it possible for a moon to rotate around its o...
The setting I've cooked up for a D&D campaign I'm running features a fair amount of buildings that have been totally abandoned by civilization for hundreds or even a thousand years. Obviously w...
I am creating a fantasy world in which Earth has a second moon with an orbit between Earth and the current moon. The orbit of this new moon is faster because it's closer to earth. I'm not much co...
I want to know if a planet with an atmosphere identical to that of Earth could be big enough so that from no point in the lower atmosphere it would be possible to appreciate the curvature in relati...
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...
I've been trying to create a Earth-like planet but I'm not sure if my planet's atmosphere is breathable. (It's mostly the amount of helium I'm worried about). I've tried to make it Earth-like whil...
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...
Imagine an Earth-like planet orbiting a Sun-like star in the inner halo of the Milky Way. As a halo star, it will likely be somewhat metal-poor, having formed early in the life of the galaxy, but o...
The setting is in a region of a planet comparable to Earth's California in regards to location. The soil is extremely rich in nutrients and subsurface water. But for the past three million years th...
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...
We have earth at the beginning of the 15th century, and suddenly the biggest continent disappears. There is nothing left of it, no animals, people, lands, anything. I don't think the details of th...
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...
This is a slight continuation of my other post where I was trying to create realistic hollows with weather due to temperature changes due to bio minerals called Hearthstones. I was wondering if pla...
I'm working to design the atmosphere of a fictional planet inspired by Venus (let's call it Cael). Cael's atmosphere at an altitude of 50 km is essentially identical to Earth's atmosphere at sea l...
In a not so different fantasy world, whose physics and thus are similar to our own how would including penguins affect the look and function of a typical arctic ecosystem. For the purposes of this...
Taking into account the some limitations of the square-cube law, biology, and aviation, I have tried to make a dragon-like creature and a hominid that participate in a symbiotic relationship. For ...
The only limiting factors are that it has to be in an area near to the ocean and to mountains (Similar distance as the Himalayas to the Bay of Bengal), and that it has to be in a hospitable place, ...
How could blue soil exist, in a realistic earth-like world. The world may even be earth. First off is it even possible - could soil like this exist given the requirements below? (if not then why?)...
its my first time posting here and i hope i do it right (watched the tour and all that). I've designed a World Map and would want to know if it looks realistic like that in terms of positioning of...
Problem statement There exists a thriving Bronze Age civilization in a gigantic rainforest, bigger than the Amazon and Congo put together. This civilization is built in on the flood plains of a mi...
For a certain reason, I needed two habitable similar earth-like planets very close to each other. After various information gathering, I gave up on double planet and gas giant moons, because tidal ...
I have a world where prehistoric humans were kidnapped and transported to another world. This other world is Earth-like, with mammals (also transported from Earth then later diversifying into othe...
In a previous question I asked if a world similar to that envisioned in the Mars of Edgar Rice Burroughs / H G Wells could exist? And if so would canals be a practical way to make the planet habita...
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...
We all know the tale of Jack and the Beanstalk--a farmboy sells his cow for some "magic beans", which in turn grow into a mountainously tall stalk that led him to the land of a giant. Now, scienti...
My world is very earthlike and I am looking to create a bird that primarily eats bone marrow. I wanted my bird to crack the bones of the carcasses to eat the marrow inside. What would the ideal bea...
One thing I like about Attack on Titan are those lovely Omni-Directional Maneuver (ODM) gears! They're the perfect combination of a jetpack and a grappling hook. I love how the thrusters are placed...
The main source of free energy that allowed life on Earth to develop was our sun. It bombards the planet's surface with photons of high energy, which provide activation energy for reactions necessa...
As we know, the Earth had one super continent at one point in the history of our planet, which eventually broke apart to become what we have today. Assuming we're talking about a planet near iden...
I was answering this question about how a living planet-organism could be possible, and realized I didn't know how such a planet-organism could produce a magnetic field. I postulated that it could ...
as the title, is there a way to levitate entire body of water in earth and make it stay in the sky (not cloud and still in liquid form) ? either natural or man made. the water either flowing or c...
I am curious that if there were a gas giant sitting close to a red dwarf with an Earth-like satellite orbiting it: How could we determine the way the planet appears in the sky and the way it i...
Essentially I'm looking for a plausible way that a planet could have odd, extreme seasons. Basically I'm wondering how (or if) a planet could work that has a week long day during the summer and a w...
or, Anatomically Correct Weebles A group of behaviorally modern humans was cut off from the rest of the earth-like planet millennia ago. (Myths hold that the separation occurred four to five ka BP...
In the world that I am making there are hollows all over the planet, which are massive underground subterranean areas of the planet. Think The Hollow of the Gears Of War series. So far the going th...
My world is set in ancient times on a planet similar to Earth, but with a different civilization and different geography (and lots of canals). I need to find a way of giving the inhabitants better ...
How would human culture and civilisation develop if placed onto a planet permanently psychoactive, e.g. because of low (but inevitable) amount of LSD-like substance in either water or air? To simpl...
My story takes place on the moon of a large gas giant planet. I have been trying to decide on a way for the moon to be as Earth-like as possible, but I have now decided to ask the community for hel...
The question about a diet of dust brought up a few creatures that survive on dust, however they were all insect-sized or smaller. This got me thinking about the Blue Whale, which survives on a diet...
If an Earth-like planet had an older, red sun "” or maybe just a reddish sky due to some property of the atmosphere "” how would that affect the growth and/or adaptation of plant and animal life on...
Maelstroms are ginormous whirlpools. They can exist continuously in an area. They're cool. The question is, how large can they get? As large as an island? Could a maelstrom have a diameter of 60 o...
I'm looking for a rock from which my island is constructed. It needs to be: Either created from the sea or via intense pressure/heat Capable of trapping layers of gas beneath it White(ish) I wa...
A Smaug giganteus. If you do as much as think about slaying it, I'll force feed you gasoline and shove a match down your throat. Sungazers are awesome. They're so awesome I decided to base some p...
I usually like to leave some wiggle room for myself when fleshing a concept out. Dragons make that sort of impossible, same's true for nanomachines but ripped senators are a question for another d...
Is it possible for an Earth-like planet to exist where the light reflected by the moon is, not as powerful, but close in intensity to daylight? And if so, what would be necessary for it? A moon mu...
Assume we have an Earth-like environment. If a tribe with only early medieval technology were to settle in a mountain environment: What resources would be needed to deal with the elevation, co...
Pretty simple (in theory that is) question for one of my worlds. I heard carbon fluorides are intense greenhouse gases but otherwise harmless and didn't lead to large issues (atleast none that I co...
