Somewhere on DeviantArt, there is an insightful tutorial by someone named "Uzlo" on how to create anatomically believable angels. Among the instructed details is the possibility of developing a se...
Tengu are humanoid creatures with many avian features, including wings and beaks. Now, this is a problem when it comes to disguises. Disguises in this setting work by covering one's body in utilit...
The creature was originally a human, altered by an external agent that basically remade its body (carbon based). The creature is roughly 2 meters and relatively light. It is humanoid and boneless, ...
For a story, I need to find a way to justify the limited cognitive capacities of an entire race that thrives on biomass, capable of eating anything that is inherently biological. This race is dri...
Imagine a spaceship entering Earth's atmosphere, it has lost control of its engines and is relying on its reverse thrusters to decelerate before crashing into the Pacific ocean. So in an attempt ...
I don't know much about hurricane/cyclone and how to created it (nor know the difference much, so bear with me if i make mistake), so I want to know what kind of plant organs or ability need to ach...
I'm curious what factors a terrestrial planet impacting the Earth would require for the impact to cause negligible damage to the larger planet, while destroying the Earth.
How might an enterprising spacer, mining the rings of Saturn, go about quickly measuring/estimating the velocity of and distance to a nearby moving object (asteroid, habitat, pirate, etc)? Bonus po...
This, ladies and gentlemen, is Melalo, described in the Book of Creatures website as "the oldest and most feared of Ana's children." His name literally means "filthy", "dirty" or even "obscene"....
What modification would a plant "” especially tree "” develop in a world where everything is made of sugar, caramel, cake, syrup, soda, etc.? Think of something like Willy Wonka's Chocolate Factor...
I've got my wizards, who operate by vanilla human biological laws and metabolism. They've got an organ in the pelvis which has its own mechanism - not breaking the laws of physics - which stores en...
A plot point of my novel is that the pilot accidentally finds a planet that is being purposefully hidden (i.e. been deleted from all star maps). It starts with him arriving at a location that is j...
A human crew of 6 has been sent on mission to Mars The lowest energy transfer to Mars is a Hohmann transfer orbit, which would involve an approximately 9 month travel time from Earth to Mars, a...

I was wondering if there is a scientific way to explain how my characters are capable of extreme levels of strength when engaging in combat. My characters are biological but have implants that all...
Please note: I am asking about planet orbiting a star, not a moon orbiting a planet. So I've been trying to get this planet down for a long while now but there are still so many pieces of the puzz...

So in my world there's a creature as big as a common rodent or as big as a rabbit in size. They live in packs, usually burrowed, but occasionally come to surface to get food. The alpha male is task...
Ecosystems like the african savanna have lots of megafauna which to some extent compete with each other for the same prey/vegetation, but still coexist just fine. So how do I construct similarly d...
You are 70 years old but you look 50, this because you have always maintained good health, mentally and physically. After experimenting with various clones before, you decide it's time for you to ...
So in my setting there is a small and exclusive group of people that have access to devices that work like computers (but which are not the same as computers. They do not use semiconductors and ele...
While I'm working on the Magical Artillery, let's look at another common spell. Mage Light is a very handy invention. When cast, the spell creates an orb, 13 cm in diameter. The orb radiates whi...
Imagine your spaceship encountered a gravitational anomaly and discovered that you are lost in space, your computer tells you that you are still inside the Milky Way galaxy but it cannot find the S...
Pegasuses in most works of media are often depicted as hexapods with four legs and two wings: The only problem is (from what I understand) no vertebrates on earth are hexapods, so I've decided ...
In modern day society, few or many people have been fascinated with integrating robotic parts to their bodies. But sometimes that idea is taken to the next step, in which people want to have their ...
So, in the S.S Portland (The main setting of my story) there is a variety of rooms. A lounge, a lab, etc. so, i was thinking that at some point, the lounge would be changed out for a 0-g pool. A ba...

A major plot point for my story is the Protagonist stumbling upon a planet that was purposely hidden from the rest of the galaxy (at the edge of the galaxy) as it's being used by high level governm...
Consider a planet with Earth like gravity but an atmosphere that is 10x what Earth has at sea level (atmospheric composition is equivalent to Earth). If the vegetation is similar to Earth's, would ...
We have a variety of ways of describing our location here on Earth. We can refer to a nearby landmark (eg "by the City Hall"), we can describe our location relative to an area (eg "in the South of...
