This question has been asked in similar forms on this site already with some good answers like here: What Color Can the Sky Be? How could the sky be orange in a breathable atmosphere? What woul...
Premise and research I am simply trying to find a reproducible framework for use with creature-design. In my research I have found the larger an animal is, the more likely that animal is to break ...
Let's say some magic aliens come and prank us. They, in one step, remove out the innards of the earth, and put everything on the surface on the inside. They make some artificial gravity so we stay ...
The normal condition of life in a planet (Earth right now) is that below us is the planet's core, and above us is the sky. Now if there's a hollow planet like above, is that possible? How does ...
I've been toying with a concept for a hollow/inner Earth universe in which I would like to achieve an even distribution of light. The pickle is that the "sun" of this world operates like a beacon/s...
I once show a picture depicticting the idea of an ultimate solar system: Image Copyright Sean Raymond In this solar system there are 8 planetary orbits, each containing 52 equal-mass, evenly-spa...
There is a popular belief that the muscles of our body are controlled only by electrical impulses. This is not entirely a lie, but ... From what little I have researched, the nerves send a command ...
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 current world population is around 7 billion living people and 107 billion dead people. Since the population is increasing steadily and faster than ever, I was wondering if we could ever reach ...
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...
How many rocket launches are needed to change the axial tilt of the Earth so much that it is noticeable with instruments available today? We can assume that we are talking about the heaviest rocke...
My main antagonist is an infant Great One that's been imprisoned below the Moon's surface and I want its influence and physical form to have a weakness to direct sunlight which, I think, gives me a...
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. ...
We know that Gor, or Counter-Earth, is not stable in a long-term sense. Let's handwave that away, or assume that we are dealing with a temporary span of time in which the instability is immaterial....
The world is Earth, probably west coast of the USA, in the throes of severe climate disaster; major storms, earthquakes, droughts, fires and floods are the norm. I am looking for a way to suddenl...
We are living on this big lump of rock called the Earth, drifting ever so continuously through space. Now imagine a tiny but immovable object in space, a single atom of 'unexplanium', locked in sp...
Suppose that we pare down human consumption to a minimum survivable level across the Earth, and devote the entire surface of the planet (as well as the planet's interior, if needed) to support as m...
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...
Earth has stopped rotating. Maybe Superman started flying around the Earth backwards to turn back time, but hit a wall of kryptonite just when the Earth stopped rotating. Or Stupendous Man hit the ...
I was reading up on Mars thin atmosphere and was wondering how could Earth becomes like the red planet except it only has only 100 pascal (air pressure) at imaginary sea level? Mars is 600 pascal o...
I am currently reading an eternal golden braid, i've gotten as far as several lengthy chapters about the brain. He talks about neurons and symbols, what 'meaning' is and there is a lot of hypothe...
[Edit: I'm not looking for 100% realism. I'm looking for an explanation as realistic as possible, possible with just few exceptions to physics.] [Edit 2: In my imagination these worlds are differe...
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...
Evil Wizard got his hands on a Handwavium Wand, and wished the Earth's magnetic field no more. Now the surface is vulnerable to solar wind, solar radiation and cosmic radiation. How long will it ...
One major problem with living underground is you lose all of that wonderful energy provided by the sun. This energy is useful for many things including growing plants for food. A window is effectiv...
So, we've gone off to another star system and decided to build a Dyson bubble--a continuous statite, supported by radiation pressure, surrounding a star--with a surface gravity of 1g to live on. N...
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...
Being at Anime Expo last weekend got me thinking about all the "trapped in another world" anime I watched as a kid: Inu Yasha, Fushigi Yuugi, Escaflowne, etc. The general plot of these is that a hi...
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...
I saw this a while ago, and it has bothered me ever since. Imagine a world where you know everyone is going to go crazy in exactly one day. The entire world's population will try to find and kill ...
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...
Very narrow question: assuming an immortality treatment keeping people at a biological age of a fit 30's, free of infections and cancers & ruling out death by aging, how long would people live ...
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 ...
