The talaria is the name of the winged sandals or shoes famously worn by Hermes in Greek Mythology. If someone were to make a high tech gadget which the attached beating wings to a pair of boots, ho...
I'm designing an Anthropomorphic Lu-pine. (Get it? Cuz it's technically a tree, but it looks like a werewolf.) They are mobile, omnivorous plants, slightly larger than the average person. They are ...
I am aware of the possible consequences having a planetary ring may cause on a planet, but since I want my nights to be dark and not giant-reflective-curve-in-the-sky bright I've decided to make th...
In my fictional setting, the planet that people live on, called "Nearth" has one smallish very dark moon close in, and a large moon farther off with a very high albedo. Nearth is exactly the same...
In a story I'm writing, there is a species of extremely rare cave dwelling bird. A scientist and a plummer have to find a specimen of this bird before it goes extinct. When they finally find it, th...
In some universe,with physical laws the same as in ours, our world is some kind of "lab environment". Our solar system is enclosed in a balloon-like sphere with a radius of a few light-days around ...
I have been trying to figure out a way of explaining how an advanced society some time in the past built an artificial planet with a black hole at its core and the effects that would have on the pe...
I had the idea for a group of advanced humans using technology to rework their bodies so that they lay eggs instead of giving birth to live young, just like a platypus (possibly to survive in an al...
For the obvious reason of weight, our modern space stations and satellites are made out of metal or lightweight compounds to reduce cost. In a quick Google search, about $20,000 per kg is the cost,...
Let's assume we have a working FTL drive and thus interstellar travel is possible, either by traveling at very high speeds or by instant teleportation (the two main subtypes of FTL drives in sci-fi...
I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and less ocean depths. The world orbits a binary star system at a distance of the ...
In this world human-like people have skin that is unbelievably difficult to cut through and I was wondering what biologically creatable material is flexible enough to act as skin but it also essent...
Before I start, let me say that I know that what animals think and feel and whether they do it is a highly, highly debated topic. But, for this question, let us just assume that many animals think ...
Ok so first of all, let's imagine a civilisation on a planet. The planet has a relatively low escape velocity, say 6 km/s and maybe an atmosphere 30% - 50% the thickness of earth's atmosphere. Now...
I was reading this question earlier today. It asks about the characteristics of global winds in a modern-day earth with Eocene-like temperatures. I'm here to ask about other kinds of weather in the...
I've been grappling with a story for a while, involving a scenario where gravity starts to fail. The goal of the story is mostly how people react to the knowledge that the world will end. But, I al...
In my world I have a region of desert, bordered on the east by the steep cliffs of a tableland or plateau. The plateau slopes gradually down to the east coast of the continent, a distance comparab...
Often times a mongoose will prefer easier prey than a cobra. However, getting down to brass tacks, should the two fight, it's fairly axiomatic that the mongoose takes the win the majority of the ti...
The succubi are popularly represented as women with horns and bat-like wings. They feed on the vital energy in myths, but could a humanoid creature resembling a woman evolve and feed only on human ...
I'm working on a map of a single continent or large island, and I want it to have some distinct biomes. What are some simple rules to determine which biomes could possibly be near/adjacent to one a...
I'd really like to write a story taking place on an alien world that involves a totally new kingdom of life, and I'd like it to be at least somewhat realistic. The idea I have right now is a whole ...
Info I've created a pine tree that stabs its needles into people. Here's the way I did so: Using genetic engineering, my fictional scientists inserted keratin-producing genes into a pine tree (gy...
In an alien atmosphere, where methane is the main gas instead of oxygen and ammonia is the main solvent instead of water. Similar to how photosynthesis on earth plants work, by taking in carbon dio...
So, in my setting, there are dwarves that make good steel. Shocker, I know. To refine the ore, they rely on the bloomery process like everyone else, using anthracite (when they can get it), charcoa...
Is it possible to build a garbage recycler that turns residues into its constituent elements using plasma and accelerating it through a magnetic field? The technology level is around that of the t...
