I'm working at a story about the future of life in our Solar System. Humans have gone millions of years ago, but they left behind them a group of highly intelligent but not superhuman AIs with the...
Space is vast and lawless. Private travel is commonplace, and pirates have become a significant problem. People mainly fly orbit-to-orbit craft that have chemical rockets and no one is running arou...
My setting is a habitable moon with freestanding water orbiting a gas giant. Originally I thought the gravity of the jovian world would tend to draw water toward the tidal bulge of the moon itsel...
So, I'm familiar with Steam, Electric, and hand powered machines... What else can you do to power a machine (say, for example, a car or a pump)? Requirements: Assuming you build everything from ...
In the book I am writing, I am going for a a partially terraformed Venus setting. I like the concept of floating cities, but I want to be able to make it a little easier to live up there. If coloni...
On a world I am building, the day/night cycle last 9 years, meaning that there are interesting forms of life. Plants are the most interesting of these living things, which have many interesting for...
The conclusion of my question Is it possible to have a planet unsuitable for agriculture? was that the most plausible reason for preventing agriculture from developing (beside nomadic herding) was ...
Think about a scenario in which, on a given planet, a complex life form has already evolved. In your opinion, what are the odds, for this complex form, to evolve towards intelligence? With the...
I am making a game folowing the development of civilizations on an alien planet, however as i am almost done with the geography of this planet, i have come to realize that my continents which are s...
On the picture there is a building that slightly inspired me and convinced me that building like this indeed could be built in RL. However I have the following question. Could a building like th...
We know that Earth creatures can generate high-voltage electricity (your nearest electric eel can attest to that). We also know that ordinary air at Earth atmospheric pressure can be used as a las...
If I were to attempt the colonization of a planet with preexisting life, how would I manage to pinpoint a candidate planet from the comforts of Earth's orbit? I am interested in the stars somewhere...
I am writing a book where there is a binary system with a red and blue star. There is planet with the same properties as earth orbiting in a habitable zone around the 2 stars. The question How c...
Let's say that hundreds of years from now our posthuman descendants finally do good on NASA's promises and build an Alcubierre drive or a true reactionless drive (either one works for this example)...
Gargantuan carnivorous worms with layers and layers of flesh rending teeth are a pretty common sight in some science-fiction stories. They tunnel through earth and sand as fast as a car, sensing th...
I'm working on a planet containing an atmosphere composed mainly of sulfur dioxide, with, notably, only trace amounts (if any) of oxygen. Is such a planet one that could realistically pop up in ou...
I think of a world of islands floating in the sky. The planet basically is (was) our Earth. For some reason all that is left is a small ball covered nearly completely with water. Pieces of the shat...
So I'm creating a world in which humans have a close sister species very similar to the Japanese Nekomimi seen in anime and manga. Eventually, the humans turn on Nekomimis, perceiving themselves as...
So assuming their existed an Oracle, what effects would it have on society. Assume that everyone has access to it similar to using a library where the books can't leave. Properties of the Oracle ...
One of the inspirations for this was Tactics Ogre: Knight of Lodis, where I liked their depiction of slithering, combat-worthy mermaids. I've been trying to develop mermaids who make pilgrimages t...
So let's say you live in a terrifying post-apocalyptic world. For whatever reason, this world is now infested with cockroaches the size of chickens (similar to radroaches from the Fallout games, bu...
This question began due to a certain fictional monster. Where it was stated to be able to secrete explosive goo activated by its saliva, which would coat its boulder-like arms and explode when smas...
So Turbines in Space don't work, how about sticking beefed up versions of regular wind turbines near the top of a space elevator? My thought is that the elevator at the top experiences some serious...
Kind of a "universal donor" or "universal recipient"? Aliens that can take on the qualities of several kinds of species and recombine them to make a kind of "super" being?
Solar Sails are a great, low-impact way of driving your spacecraft. Whilst wind turbines are a low impact way of collecting power from the wind, however, they only work when the wind is blowing. M...
