I was just reading this question, which just got me thinking about whether evidence of civilization would last longer on the moon. Civilization What sort of civilization am I talking about? I'll ...
My fantasy species has the ability to swallow small to medium appendages whole. They're known for biting off and swallowing hands and feet. A snake like jaw could work but how would it still mainta...
Because vanadium dioxide experiences a sudden phase change at 67° C, instead of trying to make small changes to gradually contract or expand muscles, could an alien instead have many smaller muscle...
Basically, I need one main character to be comatose and the other one trying to save him. The antagonist has to give the main character a specific time period to jump through hoops or whatever to g...
Hybrid dirigible airplane with an extremely large surface area on the top and bottom. Talking at least 100 km2. It would likely be several modular pieces put together, given its size. It would n...
The recent total eclipse, got me thinking about how it would look in my world. I have a earth-sized planet with a ring system, a couple of small moons and 1 or 2 bigger moons. How would a planet...
There are few examples of radiotrophic ecosystems on Earth. Of those discovered, the radiotrophs are limited to single-celled organisms and unique mutant fungi. The reason seems to be due to a lac...
I am attempting to make my species of elves more alien to humans. My plan is to change their physiology in a very specific way. How realistic would it be for them to have retractable claws simila...
Imagine technology, possible achievable in short time (maximum half of the century), that we can use to build aquarium that won't break because of internal damage (water pressure, badly distributed...
I know that certain animals have the ability to see in darker areas but not in pitch black due to a special ability they have in their eyes which also gives them that glowing effect. Could elves ha...
Since we just had an eclipse, I began to think: what would it look like if a planet had rings and two moons? Now, there are two solar eclipses going on at the same time! What would the sky look l...
My story premise is that a human expedition to Europa has happened and the travellers have tunnelled through the ice and formed a colony in the ocean. When they breached into the ocean, they disc...
So I'm thinking about writing a fantasy and I want certain parts to be plausible (though I'm sticking way towards the end of soft sci-fi). In the world I'm creating there is a cataclysmic tide tha...
Premise One of the many conditions needed to support life (as we know it) is a planet with a surface protected from deadly radiation from a sun or even other sources. In the grand scheme of things...
In a world naturally formed where some magic exists but is mainly used by sentient species, I'm trying to come up with a more or less scientific way to explain how this special, rare ore (going to ...
Among other things humans are fertiliser. Orcs are capturing humans as slave labor and fertiliser. What do human bodies produce/store that plants need to grow?
I am wondering about this map, from the game Albion (not Albion Online): The island on the right (Umajo) is an arid one, mostly covered by sandy deserts, except for an area of savannahs at the ver...
Spaceships are a peculiar thing; as are the things inside them. Humans... Humids... Humies - the colloquial term for those crazy enough to make a living by crewing these hulks of metal. A special b...
Is it possible for an asteroid belt to form around a sun? Think of our asteroid belt, but instead of where it is now, it would be where Mercury is. Also, and I didn't have enough room to put th...
This excludes metal stakes, knives etc. to the heart, it's not the bleeding out that's the issue. Just for some reason, a wooden stake to the heart ends a vampire. Why? Assume the type of vampire ...
I have a planet which was created by a God, who is experimenting with it by making it spin at an incredible speed. At the equator, the gravity is reduced to half by the centrifugal force generated ...
The ground shakes as a colony of Triopticpelorovenatorius Baromassobrachiosaurus (T.B.) shamble across the forest floor. A glorious mix of blue, purple, and green colors shift under the treetops as...
In a SciFi world I'm building with other people, we'd like to create a planet with an infection outbreak going on. There are wildlings. They are pretty primitive, have stone tools and wood houses. ...
A group of ships I've made are supposed to be modular in design with each modular hull segment being self sustainable both in terms of power needs and crew upkeep (oxygen, food, water, etc.) I've ...
The probe in my mind is unmanned, with a super-reflective surface to deflect most of the energy from the Sun on all wave length, only absorb enough to power its operation. Please also elaborate i...
