The Lusca (its name meaning 'Octopus Shark') is a cryptid from the Bahamas, supposedly a 6-9 meter (or even 23 meter) long man-eating Octopus that lives within the blue holes, dragging victims down...
Is it possible to keep the egg of my humanoid character without hatching for centuries, but still able to hatch when proper care and the appropriate environment is provided? My planet is a extremel...
I'm in some urgent need of advice about linking together biomes in a realistic manner. Can a taiga connect to an alpine tundra to the north, and a steppe to the south? Then what would branch off of...
If there were people with wings, who didn't want to be naked all the time, what clothing could they wear, without it interfering with their flying? Note: I am assuming arm-wings, like birds, but y...
I searched the site and found answers saying hard light can't exist. Apparently in the three years since the last question was asked, scientists started making inroads on making solid light a reali...
Two Earth-like planets collide at a (relatively slow) speed of about 1,000 kph. For all questions regarding the size and composition of these planets, just think about Earth - and these two planet...
In a lab at Caltech Ken Libbrecht has been simulating snowflake formation and under absurdly exact laboratory conditions, they have been able to create almost identical snowflakes. Clearly, in th...
I'm making a world which is set on a planet with two smaller "bubbles" of atmosphere at the poles, and a more stereotypical atmosphere that surrounds them. Each of the three atmospheres has a diffe...
Suppose there exists a magic-based civilization. Their mining techniques are medieval and their understanding of organic chemistry and biology are on the Enlightenment era level. However, they are ...
I have a civilization that lives on a planet located inside a nebula (and orbiting a normal, sun-like star). Would this nebula somehow interfere with/ obscure the sight of a rogue neutron star/ b...
There's a lot of talk on futurist blogs about mining asteroids for propellant and other resources for space travel, but I have something else in mind. Could a spaceship, starting out in geocentric...
I have an idea for a futuristic way to travel for my Story. People get into a capsule, and it launches itself extremely fast in the air. What would be needed to make this happen for real and what c...
I am trying to recreate King Arthur's the Sword in the Stone using chemistry. I have a couple ideas how this could be done Would any of these work or how it might work? Arthur removes the sword f...
Suppose some magical civilization on Earth-like planet can create portals. Any given portal entrances are spherical surfaces of the same radius. Any particle enters one sphere and exits another in ...
Newborn humans are born in a very undeveloped stage compared to other mammals. This is because if they stayed any longer in the mother, their head would become too big to fit through the birth cana...
Our protagonist lives on one of a group of remote islands where she makes her living harvesting a peculiar fruit. The edible part grows in the middle of liquid-filled sacks that hang near the top o...
I want to write a story on Earth as it is now, with the sole exception of one large island nation. I plan to introduce elements of mysticism into the story as well, but I would like to keep these s...
Can we create any electrical equipment which works in the opposite way to a bulb, such that is whilst it is switched on all the light in the surrounding area gets absorbed creating darkness?
In my world there is a forest of huge trees which people can't or won't chop down. The trees are similar to redwood trees but they have a large crown and no lower branches. The forest is quite dark...
Are there any unique challenges life would face evolving on a planet orbiting a Cepheid Variable star? I'm aware this is a broad question, so to narrow it down, consider this a question about Grea...
The chicxulub asteroid impact caused climate change, and the climate change caused a mass extinction. But many land-based animal groups survived, crocodillians, lizards, snakes, turtles, frogs, sa...
Say a group of people travel to a different planet where they have to wear spacesuits to live (because there's no oxygen and because of the atmosphere's density). What would happen if they planted ...
A violent way of rendering a planet uninhabitable being the obvious: accelerate a large enough object to a sufficient velocity that everything on the planet goes the way of the dinosaurs. Put brie...
The setting I'm interested in would involve a cold planet (cold enough for most bodies of water to be frozen - I'm thinking of an average global temperature of -20C or below). The simplest way woul...
In this world, a progenitor has created a mass of order out of chaos, with the possibility of entropic fluctuations increasing the further out from the center you get. What do I mean by entropic fl...
