I've been working on a fantasy race recently of sentient bipedal salamanders (sorta) and was talking with a friend about them until one of us realised that since they're amphibians they would breat...
A light-year distant from Sol saw the collision of a massive space-born battle fleet against an awe-inspiring dreadnought. At one point in the battle, the flotilla fired rail-guns with 100 metric ...
There's been a few questions about making big bugs before and the consensus in they can't get much bigger than 3ft or so (which in reality is still huge). Catch is, you need quite a bit of extra ox...
I know a similar question was asked whether gas masks could be used to survive in space but it didn't quite focus on the parts I'm interested in. I'm building a world in which space travel is regu...
In the distant future, space-stations use centrifugal force to emulate gravity, effectively being a cylinder (or something similar like a wheel) spinning around a central axis at high speeds. A sp...
Plastic is a huge problem in our lives. One of the ideas is to engineer plastic eating bacteria or fungi. Experiments already begun, and accidents already happen: a team of international scient...
I have a colonized asteroid that is roughly spherical and has been hollowed out. To create artificial gravity I spin the asteroid creating a strip of 1g gravity around the "equator". What would hap...
In a future Earth it has been discovered that earthworms can actually create wormholes. There is a lot more to this and I will be asking other questions, however at this point I just want to know...
I am developing a species that gives birth to live young after a very brief pregnancy. The infants are somewhat underdeveloped due to this fact. The harsh environment of the mountains means that th...
My semiarboreal humanoids have a build quite similar to humans, apart from some more specialized arboreal adaptations. They live in rainforests quite similar to the Amazon Rainforest. Though trees ...
I have recently been interested in Antarctic bases. They seem really interesting to me. I don't know all that much about them. One that came to my mind is SANAE IV. Some bases can support more th...
Dragons are biologically immortal creatures that have evolved the most versatile sexual reproduction in existence, they can morph through a cocoon into any other species from the animal kingdom tha...
What would be necessary in order for bubbles to rain down from the sky, whether they are actually soap or something else? Would it even be possible? Aside from a bunch of little kids (which would ...
I'm trying to create a system where a gas giant has two moons in binary orbit with each other. I'm trying to get that James Cameron look with the gas giant on the horizon, but also have a equally s...
EDITED to address the above suggestion. See below. Most animals breathe in oxygen and breathe out carbon-dioxide. Most plants take in carbon-dioxide and release oxygen. Waste products from ani...
it's pretty straight forward, how could a scientist such as a doctor, identify that nano-robots are the cause of some disease without knowing what it is looking for ? It would somehow need to be b...
I have a spherical spaceship that is about 2 kilometers in diameter with an outer clear, yet strong shell. This spaceship is largely made up of empty space occupied by air. Aside from this the spac...
My Dino theme park business didn't end well and I reluctantly fall into depression and decided to go into suspended animation to seek a cure. 200 years later, a lady claims she works with the milit...
I am new at this site, but I've been creating a fantasy story for a while. Now, I'm stuck. I would really like cat people (neko) in my story, but there is a problem! you can't just stick cat ears o...
An evil scientist has engineered a plague that would kill anyone with an xy chromosome pair. This plague has systemicatically spread throughout the planet, killing all males within the population. ...
My fantasy world is slightly larger than earth so that discovery of the continents becomes harder (about 20% surface should do it). But at the same time I want to preserve most aspects to make it l...
Between a species that is hermaphroditic and a species that has males and females, then what would be the pros and cons of either one from a biological standpoint? Anything not regarding the biolo...
Okay, trying to figure out this math guys! This may be simple math to some of you, but not me!!! I googled various ways of asking this question and got some good results, but I'm looking for a sim...
The problem is the following: let's say we have a miniaturized satellite*, X; we know its position, velocity, acceleration, the forces applied at any given moment; we also know its mass, its d...
Suppose we begin to colonize the moon. Assuming the building materials and biological material are all imported (not taken on-site), would it be possible for the moon to become massive enough to fa...
