I've got this ferret shaped land creature from a dream that can make its body expand so it looks sorta like a fat sausage with limbs. It sucks in air with its big mouth to expand. It lives on a wor...
So, I'm building this world where most of the lifeforms, for one reason or another, are reptiles. Now, I know there have been reptile dominant periods in Earth's history, so it isn't impossible for...
Using our own Earth and Moon as a template is it possible for a second large body (One quarter to a third of the Moon's Size) drifting close by to be captured in a stable and permanent orbit? ...
SPOILERS FOR ATTACK ON TITAN, READ AT YOUR OWN RISK... Hardening, or Titan hardening is an ability posessed by certain types of titans in the anime Attack on Titan. Since the setting has rifles ...
How would an alien organism survive on a diet of rocks and mineral ores, and what kind of materials would be the most sufficient? Also, what kind of teeth and evolutionary traits would they possess...
Imagine a spaceship capable of achieving faster than light travel uses several transporters to allow crew members to move around its interior at the constant speed of light. What happens to the cre...
This character has a set of dragonfly-like wings. These are not normal for her species, and would normally be something of a birth defect requiring amputation. But through liberal application of Cl...
In a very large and decadent galactic empire (think of Asimov's foundation empire), a new technology leap allows planet's government bodies to communicate instantaneously across the galaxy. It can ...
Back home, Amphicyonidae (bear-dogs) predated Ursidae by only four million years. While the latter still lives in the form of eight species, the former had been extinct for two-and-a-half million ...
Saturn has rings of debris which orbit it, and it is possible to get a satellite into an orbit that will at least last a few years, so my question is as follows; How many satellites (or just the pu...
My VR machine isn't the plug-it-to-your-brain type, but instead it's more like a "reality sphere" around your body that have some kind of gravity machine to keep you in the center of the sphere and...
The exoplanet in question is Proxima Centauri b. How might the mid-to-upper-level atmosphere of that planet be dangerously radioactive and full of airborne nuclear reagents, without it being the do...
I was thinking for ideas for new species for the planet I'm currently worldbuilding, and it occur to me if there could be a species (humanoid) where everyone looked exactly the same, and if this co...
Good day fellers. My question is - how can one decrease the digestibility of consumed food? I mean, if two characters consume the same amount of the same food, the one with such ability will get...
How long will a 400 km wide 30 km deep pit (trench or crater) with a relatively shallow (for stability) gradient of slope of 20 degrees from the edge to the surface of the planets crust be expected...
Thermal energy is everywhere on earth. If it could be transferred into electrical energy it could serve as a great energy source. This idea is violating the laws of thermodynamics. But it's not ...
Say a snake-person was between fifteen and eighteen feet long on average (this includes the "human" part of the body). That's around the length of an anaconda, but I imagine it would have to be thi...
In my world, a group of "lamplighters" seek to turn off unused stars to conserve the energy for later use. This serves a few purposes, but mainly: It delays the heat-death of the Universe to some...
In the Crescian society, on alternate Earth, the nobles have a refined sport of settling disputes with mutual assassination. The unspoken rules are that they must be carried out directly by the no...
I am working on a super-earth, about 1.5 more massive than Earth. On this planet, there's a large variety of megafauna and flora across the world. The biggest trees over there can grow to be 36 met...
I am curious that if there were a gas giant sitting close to a red dwarf with an Earth-like satellite orbiting it: How could we determine the way the planet appears in the sky and the way it i...
Essentially I'm looking for a plausible way that a planet could have odd, extreme seasons. Basically I'm wondering how (or if) a planet could work that has a week long day during the summer and a w...
as the title, is there a way to levitate entire body of water in earth and make it stay in the sky (not cloud and still in liquid form) ? either natural or man made. the water either flowing or c...
By "bryophitic", I mean "non-vascular land plants", being the liverworts and the mosses. (Hornworts are comparative latecomers, so we won't be talking about them.) Without vascular tissues, these...
i want to make an armor made of liquid, for example like dew accumulate and attached to the person or just dip into water and the water attached/carried on (just example), but it also condense the ...
