The interior of this particular Dyson Sphere is so large that it encapsulates a star at its center. Otherwise it is filled with breathable air which creatures can breath and fly in. I imagine that ...
BACKGOUND I'm working on a region for my world, and I have a very distinct idea of what I want the physical landscape to look like. Below is a description of what I'd like for the land, and an app...
I've got this planet that orbits it's star slightly closer than earth orbits the sun. For story reasons I need it to have small yet severe radiation storms and I was thinking that either a weak or ...
Global famines have dropped the population to 1 billion people and global civilization has collapsed. In an effort to save future civilization some time, you want to provide some information to ki...
What could be the effects of erosion on a rocky Earth-sized planet on a universal time scale (in the order of $10^{40}$ years)? Let's assume that: The source of sunlight is endless and almost con...
...no, I mean, supposedly, I believe there is more about it than mere kans on our part. Installations like this one are found all along the spoorwegs, and yes, around some you should tread light...
Introduction For more backstory, see here and here The 438th Harmonious Congress of the People of Mars was perhaps the most anticipated since the early years of the settlement. In a rare action, ...
Say I want to make wolves intelligent like people, to create a Canis Sapiens of sorts. What sorts of tests should I conduct to develop human-like intelligence? If it helps, the sort of traits I'...
For your consideration, a star system inside a dark nebula with a potentially habitable planet. Being a dark nebula, we Earthers can't see light shining behind the nebula. Further and therefore: ...
I've been trying to figure out a model (or find a relevant paper) for calculating the approximate day/night and periapsis/apoapsis temperature variation for an earth-like planet that has a high ecc...
In a nutshell, I've an 8-fingered bat-like humanoid (let's call them AX) and a 10-fingered 'standard humanoid' species (let's call them BX) sharing a planet. AX was the first to develop things su...
Background info During physical examination A physical examination may include checking vital signs, including temperature examination, Blood pressure, pulse, and respiratory rate. The healthc...
Human evolution has a reasonably complete fossil record pointing to the fact that we and apes evolved from a common ancestor within the last 10 million years or so. But I want a world where it coul...
I've recently discovered something great: the Schwinger effect. It says that if you concentrate enough power thanks to laser into a single point in space, it will spawn a pair of proton and antipro...
One of the worlds I'm building has three moons in 1:2:4 resonance, with the full moons syncing up once a cycle, meaning all three are full at different times but at the same time when the moon with...
So I have a planet that is slightly larger than Earth, orbits an orange star slightly closer than earth orbits the sun, has extreme weather patterns and volatile tectonics. It has bad storms, tempe...
So I'm guessing you guys know about the speculation that life exists on Titan. To me, this is very interesting but many point out that it would probably only be microbes and unicellular life becaus...
So I've created a Cerberus creature that is a group of three hyena-like dogs instead of one organism. The three individuals are linked together, much like an ant colony or bee hive. They would be l...
A nomadic tribe exists deep in the vastness of space, calling a rogue celestial object home. Their Skywatchers have seen another lonely object that will cross paths with theirs, so they begin prepa...
I'd like to explore some details on a so-called water-ball planet (i.e. a planet in the habitable zone of a sun, covered by a 100 km deep ocean). I am particularly interested where life could devel...
Think Moa, very big bird, kept as livestock in a western-ish world. Could they be safely lassoed? Their necks are quite long and, I imagine, delicate, at least when compared to cattle or horses. If...
I am writing a short story in which a character is ejected out of an air lock in a space ship. He quickly re-enters (disregard how he does this) and the chamber re-pressurizes, but he is exposed to...
BACKGROUND In the antiquity of my world, a college of pyromancers attempted to create stronger magnifying lenses so that they could apply their ability to control heat to ever more finely detailed...
I am looking to have a creature which is basically a small human sized bat, something like man-bat from the batman series. It would ideally fly or at least glide and would regularly hang upside dow...
Say in the later 1700s/early 1800s handwavium is discovered. It's a metal that when heated causes more way more upward lift than hot air or hydrogen/helium produces in similar volumes. Air travel (...
