No planet in the center, just a large O shape made up of large chunks of rock that in and of itself itself orbits a sun, as if it were a planet (as distinct from a ringworld). I know most of the ti...
I'm currently writing about an Earth sized planet that is 33% water and has 4 moons all the same size as our moon. All moons are 243,000 miles from the planet's surface and the planet takes 392 day...
I've seen some cool art and scenes from the Cowboy Bebop which had trade lanes made up of what looks like large rings that accelerate and deccelerate a ship. I wanted to replicate a system like th...
In response to Write once perpetual storage, is such a thing possible? Separatrix pointed me at How could an ancient race warn the future in a universally understandable way? and How might modern h...
I've been trying to come up with a genetically plausible origin for dwarves, but with little success. By dwarves, I'm talking about the jolly and burly people similar to that of Tolkien's dwarves. ...
In a world where human and dinosaur co-exist, would it be a good idea to use dinosaur as a mount ? More specific questions : Is a dinosaur smart and docile enough to be ride ? Which species of ...
I've been thinking about doing something involving bubbles of stopped (already answered here), slowed down or sped up time. What would that look like for different speeds? Is there any way of ca...
I created the above illustration to help convey my meaning, here is what everything means so that you can read it effectively: E = Earth V = Venus M = Mars The dots in the lower left hand cor...
I have a super-earth world. The surface of the world is shallower due to extra gravity, so shorter mountain ranges and less ocean depths. The world orbits a binary star system at a distance of the ...
In the short story, a man is swallowed by a giant, fictional fish. In fact, he is swallowed whole along with his log cabin and a bunch of hand-crafted tools. In a "The Martian"-like narrative, he m...
So, on the Jungle world of Qualis, the Qualian species evolved from small, tiny lizards to intelligent humanoid who dominated their planet. They built cities, from small towns to large metropolises...
I've been thinking, could there possibly be an organism that is based on the element of helium? If yes, what would it look like? (Images are welcome)
A lot of worldbuilders that I know and have spoken too, insist that unbacked currencies and items with constantly changing values would be what the economy is based on. I, however, am skeptical of ...
For a story I require an intelligent [drepanosaur]. But to work with the plot the creature needs to still have traits that don't mix well with classical vertebrate evolution of intelligence. Requi...
We're all familiar with the heroes that can't die. Honey-badger (with the claws and the angry voice), Dreadpeel, that girl with the weird cheerleading obsession... Basically they all have the same...
One of my characters in my novel has the ability to manipulate air. Having the ability to snap his fingers and increase the sound so that it would damage the opponent through a shockwave. Could any...
I am planning to make one of my characters in my novel have to have an ability to create positron beams as an offensive ability. I wonder what the effects on regular matter like a wall or a body of...
First of all I would like to precise what my species of wyverns actually are. I do not plan to make them huge and gigantic like in many fantasy worlds. Instead they are rather small and can be the ...
In a world I'm currently developing, I'm working on a merpeople equivalent (more or less physically identical to your bogstandard mermaids, for the purposes of this question), and I want them to we...
I'm writing the last issue of my comic and I'm in trouble. My villain is a member of a cosmic cult that wants to absorb everything in the universe to create a conceptual/energy pangea out of space ...
This is the kinkajou: It looks vaguely similar to a monkey - it has grasping digits on its forelimbs, it has a prehensile tail like some New World monkeys, and it primarily eats fruit - but it is ...
My world is essentially a Neptune-sized gas planet that got seeded with life and its surface layer filled with oxygen, therefore gaining a sizeable layer with Earthlike conditions. Within this la...
This question is inspired by Could a species develop the tech necessary to land on their own moon without comprehending light? Consider following scenario: a civilization of alien tricksters abduc...
This question was originally posted in the Sandbox. It's set in the same world as this question, but is not related to it. I have a speedster character whose top speed is Mach 2. She holds back ...
Info I'm designing a prehistoric-dragonfly that has little holes or perforations in its wings. When the wind flows through them, they make music (the viability of flying with these wings will be c...
