I've got a group of magical people living mostly incognito in an ancient society. They look and act exactly the same as regular people, but they are really magicians, and a side effect of having th...
In my sci-fi universe (The same as my first question) it is common throughout the asteroid belt to 'Bump' (somehow cut off and then shove a ship off of an asteroid) miners. Usually this is only don...
Dyson spheres are a staple of science fiction. Solar system spanning megastructures, they represent a significant effort by whatever species chose to build them, and a significant mass moved into t...
While working on my story, I just came up with this doubt. Is it possible to know or to detect something like a submarine in an ocean from an aircraft with our current technology? I mean to detect ...
Edit: I've written an answer of my own now, and I'd appreciate it if any of you informed on the subject of evolution could review it, then inform me of its plausibility, via the comments (Of the a...
If a planet has a core of super-dense material, how might that effect the geological composition of that planet? Specifically: imagine a lunar-sized planet, with earth-like geology and density. If...
Alright, so I'm working on a setting with dwarves in it. I've been thinking that, to make things more interesting, certain clans would have the cone cells in their eyes see infrared light instead o...
So, here's my issue. My setting's central conceit is that a myriad of human societies developed at relatively concurrent times across a large system separated by only a few light-hours. (There are,...
I'm writing a story and I was wondering on the feasibilty of having a set of bio-engineered vocal chords that would have a voice modulator built in to help disguise the characters voice, would it b...
EDIT: (Important) M. A. Golding commented that the regalecid method of locomotion would be unfit for a constricting predator, so I have completely redone the taxonomy of the sea serpent. They are n...
I'm wondering if it is plausible that a large asteroid (interstellar in origin? Or, perhaps launched from the Kuiper Belt by something big with a lot of gravity?) would be able to smash into Luna a...
Setting A nuclear war between two superpowers happens, and nuke after nuke is fired at nearly every country on the globe. The war, which lasts for about 4 hours, kills over 3 billion people, and m...
I am designing an alien civilization for a story, and I am currently in the biological part. They will be oxygen breathers, so they will need to have that oxygen delivered inside their bodies, and ...
Assuming it were possible to phase through matter/teleport, is it possible within the laws of physics/chemistry to end up stuck/fused to solid materials? Obviously we lack the real world ability t...
Redoing an old map from scratch, want to get any problems with the coastline/placement/scaling of the land before I get to work on it. I am looking to make it as believable as possible. Here is t...
Building on this question: Settings formed by Uncontrolled Terraforming of Venus and Mars via Portals My government, the Great Council of Duhurang1 has authorized the Minister of Astronomic Scienc...
What characteristics (compare those of a mountain goat foot: good grip on rocks, doesn't slip off, etc) would the foot of a dog or a wolf need to have to be useful in rocky settings such as mountai...
I'm writing a story, and in the story the protagonist designs a way to trigger artificial continental drift that takes place in 50 years, for all the continents to drift in the places he plans. Are...
In one of the documentaries he's featured in, Neil deGrasse Tyson talked about the evolution of the eye. https://www.youtube.com/watch?v=4SXHMm5I-68 The part that's always intrigued me is this: ...
The Tsingy National Park is popular for its unique karstic plateaus. These karstic plateaus are thousands of large sharp pillars or needles that stretch towards the sky, creating a wide variety of ...
Scenario: An exact copy of our world is sliced in half by a particle beam. The beam has a diameter of 40 meters and moves at a speed of 0.999c. The beam slices the earth from top to bottom in 600...
Looking most specifically regarding the moons around Saturn, Jupiter, and Uranus. I've been unable to get a concrete answer on this through various sources. I've actually read several articles brie...
Is it feasible for an ectoparasite such as a a Tick to create a symbiotic relationship with its host? The hosts feeds the tick and the tick has some sort of beneficial substance within its saliva. ...
I want to know what kind of effect a large circular space station would have on the planet if it went completely around the equator in one giant circle? Would it impact gravity or anything? And wou...
This question is kind of hard to explain succinctly, and I apologize for that. Obviously, humans experience acute effects from UV light on Earth in a matter of minutes near the equator (UV index o...
