Imagine a world where the Earth's rotational cycle is 20 hours. It has wreaked havoc on ecosystems that need sunlight. Although some plant life can adapt, others are endangered. Is there a way to s...
I'm trying to create demons that aren't just raging murderers, as much as they're enslaved to their disposition they're not completely conquered by it, with a sense of humanity and reason crawling ...
Assuming in a galaxy far far away there is a Type 2 civilization (currently on the verge of making the transition to Type 3). Their scientists predicted that the star (red giant) they are orbiting...
Given a planet without any relationship to Earth, what does it mean for the poles to be "north" or "south"? Is it something arbitrary that can be changed?
How might such a species evolve? How would they swim, navigate and breed? How big could they grow, and what complications might arise out of their growing very large?
Newton's first law of motion states An object remains with the same velocity, or position of rest unless an external force is exerted. What if we created a hypothetical universe where A...
Humans (and most animals) sleep. The reasons aren't really clear but most people believe: We have to sleep because it is essential to maintaining normal levels of cognitive skills such as spe...
For a civilization like this, firstly, I would like to know what dangers there are, e.g: radiation, cave-ins, temperature. I also want to know about the sustainability of this colony, power I'd ima...
They say that nature abhors a vacuum, but could life evolve to live in one? Alternately, could life be engineered to exist on a planet with no atmosphere, even if there is no biologically feasible ...
In Dungeons and Dragons lore, there exists a construct called the cosmos used to define a variety of planes of existence. One of these is the Material Plane, on which our normal reality is found. ...
I have a planet approximately 3.5 times the mass of the Earth. I have a moon orbiting that planet that has to be habitable as well, because my story will take place on the first expedition to this ...
I'm trying to find explanations for a strain of beans (or any other food-producing plant) that have become large, maybe as large as most trees, and about as wide in girth, that overgrows countries ...
I am developing a world on this continent: To know the world, I have to know how the weather works. Inside the white line is the continent. The blue arrows denote the flow of water. Up is north,...
While asking questions about building my fantasy world, I keep hearing about wet/dry seasons. Obviously, one has rain and the other doesn't, and I've gathered that they occur with regularity on an ...
Scenario Set in modern day Antarctica, a group of very talented scientists are working on a highly confidential scientific experiment which would one day allow us to manipulate time literally. The...
You go to sleep one day, and wake up on a different planet. Let's say the atmosphere of this planet has about the same composition as on Earth. Actually, this planet has pretty much all of the same...
I am specifically interested in a form of reproductive cycle something like that of aphids on earth, where several generations of female-only parthenogenesis go by, followed by a generation being b...
Would it be possible to "inject" or tattoo chloroplasts into a human or vertebrate and have them produce energy for said organism? I feel like just injecting plant cells wouldnt work for the body...
Let's say through some magic or other, the Earth's spin came to a halt (to the point that the same side now always faces the Sun) How would this process feel? Obviously it would depend on how long...
I'd like to tip my hat to this week's fortnightly challenge with this question by revisiting an old one. I asked a question about the Science behind a naturally invisible creature a while ago. At ...
If a centaur were to have one set of organs, how would they be placed and what sizes would they be? What limits would there be on the centaur's body?
Take the situation of a modern carrier group (Aircraft carrier, etc.) anchored just off shore (far enough that they initially couldn't run aground) with all the crews abandoning ship for land (in a...
In Star Gate, the Ori are notorious for keeping the tech level of their planetary subjects at or under medieval tech levels. It has been said (still looking for the exact source) that if everyone l...
On our world we have any number of creatures that use: Noxious Chemicals Poison(Spiders and Snakes being the obvious examples) Sound Electricity as an alternative to their teeth and claws. One...
Yesterday I was driving at night on an unlit road (nothing nefarious, I swear), and there was a truck behind me with a ridiculous amount of headlamps on, and catching a glimpse of it in my mirror i...
