I have a world that has unexpected lifeforms detected. There are to-be-revealed reasons for it, but the way the ecosystem is set up is: Microbial life is abundant everywhere There is a single sp...
Specifically, will ferrofluid at the bottom or on the sides of a shot glass perturb the fluid above it to any significant degree? I want a character of mine who is a sort of Bill Nye/Neil DeGrasse ...
In a previous question on my purely peaceful, 100% pacifist species, I asked about how to remove all defining characteristics for sexuality yet still retaining sapience. As was pointed out, I had a...
Background- Writing a speculative evolution about the nine-tailed fox and had made twenty species that range in size from cat-sized species from Indonesia to wolf-sized ones in the Carpathian mount...
Many questions describe hypothetical biochemistries, or alternatives to carbon, water, DNA, etc that aliens could use. They cite specific examples, given a world we know about, of what creatures w...
Background I'm doing a prehistoric nine-tails which would be believed to the common ancestor of the kitsune, the kumiho and the huli jing and five more species I made up, this early specimen lives ...
Needs ideas for the reason for the different sizes for ninetailed foxes i Made up. . The Korean kumiho is sexual dimorphic as the males are big as a coyote while the vixens are as big as a red fox...
Here's the explanation These are the structural questions about my "Super Dreadnought". How wide would the ship have to be to be stable on the water? Would the Caterpillar treads hold the weight...
So, let's say that through a series of strange timey wimey events, I accidentally jump-start several technological revolutions in the early 1800's. So, at any given time, technology is ~60 y...
I'm trying to design human like race where all the children are born as girls, but later in life some of them switch to male, but no sooner then 15. Usually only the most dominant women switch, so ...
A K2+ civilization wants to build a fission star, a huge mass of fissile material which doesn't collapse due to the radiation emitted by its fission decay. I know there are reactors like the aqueou...
Currently, chemical rockets have taken men to Earth orbit and the moon by combusting rocket fuel to generate thrust. Even if we develop more efficient rocket fuels and can create significantly la...
Suppose that I have come into possession of a substance, technology, or spell that functions as a perfect insulator and reflector. No energy can pass through it, and is instead reflected back the w...
I'm trying to think of ways that a humanoid civilization, post-agrarian with solid mechanical knowledge but no electronics, can communicate in near real-time over large distances. Some of my init...
Many fish have specialized organs called buoyancy bladders which allow them to control their buoyancy - effectively rising or sinking in the water. What if humans adapted this to use in the air? I...
I'm trying to build a semi-plausible world where there is native flora and fauna, but the world is subtly not quite right for human habitation. I thought that having significant amounts of copper i...
Without a doubt, the most iconic mammals of Australia are the pouch-bearing marsupials. You can find less than 250 species in that one island-continent. Marsupials have been around for 65 milli...
NASA received a telegram from the direction of Proxima Centauri stating that the abominable snowman are coming for a visit and they expect snow to fall everywhere even along the equator. They also ...
In a distant future world, people going to cinemas will not just see movies but 'experience' them. Spectators will be a part of the cast with the help of immersive virtual reality. How would these ...
Context NASA commissioned some awesome, vintage-style prints a while back advertising the colonization of Mars. Three of them stood out to me because they depicted colonization of the moons of ...
If a sentient supercomputer was created as a weapon of mass destruction, and it wants to consume humans for their flesh, why would it do that? I know this might seem too far-fetched, but if there'...
What I am proposing is a bridge making it possible to travel between two planets, I have some ideas but I would like to know if and how it would work. Maybe somehow stopping their orbit and locking...
I have a series of astronauts landing on an asteroid. I'd like to know the threshold of mass for them to not fly off into space. Specifications: Assumption is all astronauts are under 180cm, 80...
I had the idea to make an artificially constructed planet which is terrestrial, but has the diameter of Jupiter. Instead of being a solid sphere, it would be five spherical layers, with land on the...
A hypothetical species reproduces by females impregnating males a la seahorses. However, their reproductive system appears woefully ill-suited to this task. Their genitalia are outwardly similar to...
