I'm not asking about an exotic species in the modern world we know all too well the havoc that can be caused by the introduction of an alien species into an existing ecosystem. I want to know if a ...
Context I have been thinking about the Pip Boy device from the Fallout series of videogames. It is a portable, wearable computer that can gather a lot of data about the user. It looks like this: ...
I'm taking the example of a rotating wheel space station, in which artificial gravity is created through rotation due to the inertia inside. The idea in the 3D environment is that the wheel (2D) i...
Problem statement I am building a world where the flora and fauna is based on that of Gondwana, the lost supercontinent that consisted of South America, Africa, Madagascar, India, Australia and An...
Problem statement There exists a thriving Bronze Age civilization in a gigantic rainforest, bigger than the Amazon and Congo put together. This civilization is built in on the flood plains of a mi...
I'm designing an alien world on which its creatures evolved from four-eyed early life forms. However, there is a fair amount of other beings that have six or even eight eyes. How could such creatur...
Could a perfect mirror/s be made to reflect one side of the Earth from the edge of the solar system and viewed with an optical or radio telescope that is in orbit? The targeting mirrors and telesc...
I have a location in my story, the design of which needs a reality check. City Description: As my ship cut across the waves a blurred grey smudge appeared in the distance, as the hours passed...
So, this came about when I was attempting to construct create a unified Kaiju universe, and wondering about a hypothetical evolutionary path of Godzilla. However, I figured that it could also open ...
Let's say that a character moves much faster (>100 x) than a bullet. If he is shot at, could he theoretically catch the bullet (and put it in his pocket) ? What happens when he touches the bu...
So in my world interdimensional travel produces UV light. However, there are obviously other things which produce UV light/reflect it and look different. Being a non-physics person, can someone exp...
Some Context I'm creating a universe where humanity has reached the stars. They've colonized a few star systems and, obviously, FTL drives are a common thing. The part of the story I'm currently...
In my world, I have three dimensions, each of which have their own special properties. From each of these three dimensions come a master race of said dimension: From the first, the master race is...
I am designing a monster that is as large as a continent. It flies across the planet very slowly and has basically a snake form. Life cannot exist on the planet's surface so the animals are drawn t...
My current ongoing science fiction project has FTL travel that is instantaneous for the ships and their crews, but still, usually, takes years of real-time in the rest of the universe. This is goin...
As a small part of a SciFi story, a fully developed AI developed by advanced aliens (who think quantum computing is a neat, but outdated technology) happens to visit modern-day Earth. I'm talking a...
Today, dinosaurs, alligators, crocodiles, gharials and caimen are all that remains of a special group of reptiles called the archosaurs. Recently, it has been accepted by the public that birds did...
In a far future, antimatter is used for energy storage: Huge space stations with powerful solar arrays orbit the sun a bit inside Mercurys orbit, using the energy to create small amounts of anti-hy...
I am working on creating a sapient reptilian species from a mineral-rich Planet that has very little flora. I was wanting this species to use a super acid (specifically fluoroantimonic acid) excret...
Suppose a person, standing at sea level, could use telekinesis to exert a force around a sphere with a 10 cm diameter so that it becomes one-way permeable to air. As time goes on, the sphere become...
Idea prompted by Brian Greene's The Elegant Universe: String theory postulates microscopic dimensions in space. Could you conceal an object by rotating it into one of the microscopic dimensions a...
So I'm writing a book series called The Weasel Sagas (link here if you want to know more about that). Anyway, there's this character named Santa Muerte (her birth name is Beth but that's a story fo...
Suppose you want to build a large scale habitable structure in space or on a planet or moon without an atmosphere or any organics, and this would be a long term or permanent settlement, not a tempo...
So in this book series I'm writing (link here if you want to know more about that), there is this planet called Ryu 108. The planet is made up of two continents. The southern continent is heavily f...
Would it be possible to have a giant velvet worm? Not huge but big, like the size of a small dog, 20 kilograms?
