Supposing climate change continues at its current "worst case" projected rates, would we see a noticeable reduction in insects down the line? I am wondering if it makes sense to have a character wh...
I've got a home-brewed D&D setting. Diamonds, in D&D, are needed for resurrection magic, so access to diamonds is literally life and death for any country with clerics capable of casting su...
In my late-Victorian world there are independently moving automata that may act as pets or servants to those that can afford them. They require a fair amount of energy to run at full capacity, eno...
Goblins in my setting are around four feet tall, with batlike ears, a keen sense of smell, and lithe, dexterous bodies. They are omnivores, eating slightly more meat than the average human, and the...
Let's create a creature with the ability to create a loud boom with only its body. We'll start with a terrestrial predator, that gives us a good reason as to why it needs to do this. It uses the th...
I'm looking for a way to bypass the bidirectional diffusive gas exchange that happens in human alveoli, to allow aquanauts to breathe a standard Nitrogen-Oxygen air mix at very high pressures (up t...
The Guivre is an amphibious dragon from French mythology: Many of its aspects are typical of Western dragons, but there are two which distinguish it from others: Its breath causes disease It c...
If humans had wings, let's just say in the classic angel position. It's pretty obvious that we don't have the muscles or aerodynamics to actually fly with them. I was looking at hang-gliders, and I...
The three most common properties of dragon scales are: being lightweight heat-resistance just plain resistance The first two are simple: by making the scales out of a substance similar to nacre...
In my world, interstellar vessels use a drive whose design mankind learned from an extinct elder civilization. While construction of the drives is possible, the physical principles making them work...
This question is a different version of other questions that I have found here discussing a similar but different problem. The problem I'm facing here is about the excess or waste heat that an adv...
Subarenaceous animals are those which can move long distances through dry sand - like sandfish lizards, or Dune's sandworms. The main problem they have to tackle is turning the sand immediately aro...
About 100 people settled in a tropical area near a seashore five years ago. They've been feeding themselves by hunting and fishing, but now they're also trying to grow crops, including hemp and cor...
So I was surfing this website which gives rpg stats for various fictional characters in various media, when I came across this character called "The Frenchman" who apparently uses biofeedback to bo...
I thought of a concept for a dragon or similarly gigantic reptile with a special adaptation, in which they're born with scales made almost entirely of carbon. Then, over an incredibly long life cyc...
I asked a question earlier on here concerning Negative and Heavy Matter - hypothetical types of matter I created to have a working FTL drive. With some extra work, I've tweaked the concept and been...
It's possible to have lots of electric charge while having only a small amount of mass, and a black hole with a significant electric charge has properties that are different from one with no electr...
Backstory You won't believe it, but I'll tell you anyway. I'm a Level 61 wizard. If you think about it, wands aren't all that hard to use. Point, invoke, joyfully watch your enemy burn in the f...
Partly inspired by this question My Venusians are happy in their cloud top city when a small group somehow (with lots of handwaving) crashes to the surface, falls underground, and ends up in a hid...
Regarding the idea of a generation ship carrying a community of people for thousands of years to another planet: Is there is any material for an engineered structure or set of systems that will re...
If a human somehow managed to change their body in such a way that self sustaining was possible and they did not need any outside sources to maintain themselves, does that mean that they cannot gro...
Recently, I came across an inverted world map on the MapPorn Reddit made by MChainsaw. "Inverted" as in, the "continents" are now below sea level and the "ocean floors" are high and dry. (Conside...
On another planet there is a group of organisms that have colorful display patterns allowing them to attract mates. Eventually a branch of this type of organism evolves the intelligence of early h...
What would be the best configuration of solar panels on a rotating wheel space station? I am thinking about Space Station V design and dimensions. Space Station V comes from 2001: A Space Odyssey...
Considering that oil is only really prevalent on earth (where dead biomatter can be compressed over millions of years into long hydrocarbons) I began to think that plastic might be just as rare as ...
