The dominant religion on my world (created by a race of dragon-like humanoids) believes that their species originates from an ancient being that sacrificed itself to defeat a great evil at the cen...
In a story I am working on there are 5 AI on a space station of varying levels of social, image recognition and general intelligence. At least one is good enough to pass a Turing test and do image ...
66 million years ago, something brought an end to the long-established dinosaur empire. The pendulum just kept shifting between an asteroid and a comet, astronomical bolides that actually have dif...
Is it possible that life could come about on land if a planet has a dense atmosphere? (This applies to non-carbon based life as well).
So imagine people were the size of house cats, and the world's land masses were scaled down accordingly (in volume). In comparison to the original size of the landmass, how big would England be? An...
What needs to be improved or added to the structure (device) of human lungs to be able to filter toxic chemical compounds in the air (for example, in mines the air may contain nitrogen, methane, ca...
The question is in the title, but I have bolded the main details to reality-check. I hope that makes it easier to read. Details: I had the idea of a fantasy/sci-fi animal that never stops growing,...
I am an alien from outer space who is visiting a planet called Earth. The species living here, humans, have a very primitive and strange culture. They seem to spontaneously burst into dance and son...
I'm working on a novel that takes place in a fictional universe which involves creatures with long forelimbs and short hind limbs. Some of these creatures includes amphibians , reptilians and mamma...
Reattaching severed limbs is a recurring theme in many monsters, but never has it been explained HOW they reattach their appendages. I doubt the neurons would magically realign and begin to functio...
I'd like to randomly generate between 1 and 20 million stars for a spiral galaxy resembling our Milky Way. This is of course far fewer than our galaxy (estimated between 150 to 300 billion), but I'...
So, I have this draft for a story. It's basically a parody(?) of the fantasy tropes originating from LOTR (the movies) with the twist that we're following the bad guy's lackeys, who he abuses more ...
I am writing a story where a person suffers from a medical condition where the gut produces too much of a liquid called diphosphane. Diphosphane is pyrophoric past a certain small concentration, an...
Hello there, it's my first time posting, so I'm sorry if I'm going against formatting. I'm making a continent for a fantasy setting, and have been firstly focusing on geography. This continent s...
So, I thought I had the hunger related bioluminescence for my Keplerians figured out. That once the hunger hormone reaches a certain threshold, the hormone receptors on some cells of a bioluminesce...
This is a slight continuation of my other post where I was trying to create realistic hollows with weather due to temperature changes due to bio minerals called Hearthstones. I was wondering if pla...
I am designing a cold-blooded dragon about the size of a house cat with a wingspan of 3 metres from tip to tip. It will climb on top of rocks at noon when there is ample sunlight overhead. I need i...
In most future sci-fi settings, it is apparent that laser weapons (or as Star Wars likes to call it, blasters) and energy weapons in general would have replaced most standard ballistics for main in...
I want to make an alien species evolve without fear, or atleast not fear as we know it. Intelligent life, as I understand it, requires fear to encourage an organism to keep itself alive. What emo...
Many people are excited with the idea of super-Earths--rocky, habitable exoplanets greater in mass, density and diameter (because I'd prefer to go the whole way than stop at the halfway point) than...
Context: In a near-future version of our solar system, humans have established multiple underwater colonies on Jupiter's moon Europa. Many of these outposts are situated next to hydrothermal vents ...
I'm trying to create a scenario where the local star is "quickly" (suddenly up to thousands of years) removed, dimmed with reduced output, destroyed (maybe), or otherwise fundamentally changed as t...
I am wondering how will it affect earth or none at all. Seeing that Jupiter by far is a gas giant and has really strong gravitational pull while Mars is mostly dormant, weak gravity and a terrestr...
Say in the future, humanity has developed technology to the point that it allows them to traverse through other universe, each universe having something either drastically different or not so diffe...
Short version A far future catastrophe burns/melts away large chunks of the Earth and Moon. For reasons related to my story's fantasy elements, the remains of the Moon have about one fifth their or...
