If I terraformed a moon to have enough artificial gravity/atmosphere to support life, would they end up just crashing into each other? Is there a way to not have this happen, e.g., increasing dista...
In the mythology of the Lambas people of Zambia, there is a creature called the Ichisonga. It is a herbivore, and very rhinoceros-like in appearance. Upon hearing a hippopotamus, it allegedly sne...
I'm trying to create a planet with a hot desert north and south pole but a cold equator. Is this possible? and if so how? And if it's heavily related to space how would night and day work on this p...
I am creating a speculative evolution project for school (and partially for leisure) and I need a planet for my organisms to live on. I have a rough idea of what it may be like but I'm no expert in...
I'm about to break rule seven of superpowers: don't think too hard about what it does to the air. A superhero has the ability to disappear any atoms that come within 2 cm of their skin (atoms that...
Edit: I am asking in the context of alien life, should have specifyed that to begin with. I have many ideas for fantasy/sci fi races, and one that I kept coming back to is a species with bones th...
Background: An Elven nation that once thrived for thousands of years as a predominantly agricultural race was forced underground because of unexplainable occurrences of extreme weather conditions ...
I have a hypothetical world in the works and I have a rough idea of what it might be like. My idea is that the planet was life-supporting with a widely varied biosphere. The magnetosphere failed a...
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...
Handwaving the origin of one such place, imagine a universe where every part of space is filled fully and evenly with liquid water (at, say 1 degree Celsius). What would be the experience of a soli...
For context, this takes place about 300 years in the future. The space city in question is located in a nebula, completely man-made (not build upon any preexisting foundations like an asteroid etc....
Let's say that some Oriental emperor had decreed that he should move his palatial residence from China to Everest. Specifically, he wanted Mount Everest to be his palace, which means hollowing the...
I'm struggling with the physics here a bit since I'm a complete novice at this. I'm making a character whose main ability is to subvert/play around with the 2nd Law of motion. Somehow I understand...
On a world similar to Earth minus size, gravity, and a mildly different atmosphere. The weather is much more violent, causing frequent dust storms. The planet is larger than Earth and is mostly scr...
I'm struggling with the physics here a bit since I'm a complete novice at this. I'm making a character who's main ability is to subvert/play around with the 3rd Law of motion (For every action, the...
I'm imagining a scenario where there is a conflict between humans and intelligent octopuses. The humans' main mode of transport is the bicycle. The octopuses decide to stage a night raid whereby t...
I am wondering what kind of physical qualities (E.g. Short, thick pillar-like legs) a creature such as this would need to support such an incredible size. The world that it evolves on in almost ide...
Given tilt of about 90deg (like Uranus), with day & year like Venus (day longer than year), orbiting a purple (brown) dwarf (not tidal locked). I'm having trouble getting "seasons" & day le...
Welcome to the year 2170, the predictions of our grandparents were so wrong: The human population didn't cap at 20 billion, it went far past that. The global population is now roughly 200 billion. ...
In lots of barren, deserted or otherwise destroyed landscapes, there are bones of long dead animals to be found. Sometimes, it's a skull, sometimes, these are rib-cages, or ribs alone. And somet...
My character is male and eighteen years of age. He has no health issues. 'Gold' can be replaced with any type of metal - silver, bronze, steel, iron, it doesn't really matter to me. The ideal type...
I am working on a planet that has insignificant (almost 0 degrees) tilt, no moon, rotates twice as fast as Earth. I intend to create quite an exotic "biome", so to speak, in a subtropical desert z...
Given a world with similar size and atmospheric composition to Earth that has a commodity export, be it grain or oil etc, that has trade with other planets, what would be best way to orbit massive ...
Disclaimer: I am not a meteorologist. Snow forms when supercooled water droplets nucleate onto particles in the atmosphere. After forming, they grow further by both tumbling around within the clou...
I'm picturing a world without oceans. I'm not after Arrakis; I want a quite lush surface. I'd like no surface water at all, but I'm concerned that makes evolution impossible. (I imagined using chem...
