I've created a small planet, about 90% the size of Earth, which orbits a pair of twin dwarf stars and is Earth-like in many respects. This planet's atmosphere is highly electrified, with lightning ...
There are a few million cubic miles of water trapped in the ice-caps that line our planet's poles. If all of it were to melt in a matter of a few short years (somehow), London would surely be left ...
In a parallel universe the uncertainty in position and the uncertainty in momentum are directly related to each other. What kinds of effects would this have on the quantum mechanics of this univer...
I want to know the how many people can live on Earth's oxygen. Is there a point when humans would use up all the oxygen? What would be the limiting factors? Given we have charts to show the rate of...
I want to create an inland forest on the western side of a large continent that features cenotes instead of rivers. Is this possible, and if so, how can I make it work? Any requirements for altitud...
Is it possible to directly convert radioactivity to turn it into electricity? If yes, then what is the conversion rate?
A hero travels to another world that is like the medieval age of Earth. He needs a portable power generator. Is there any portable, low maintenance, at least 10 MW, reactor or energy producer that...
A soft and vulnerable intelligent underwater species, you can consider them closely related to Earth's octopus - in the way chimps are closely related to humans. Consider that clothing is often wo...
I have a species of creatures that live in packs off the coast of my fictional world's one super continent. Humans have lived there for millions of years. At one point these humans had achieved the...
What would happen to to a planet 10 times the size of Jupiter, if there was a black hole the size of a golf ball in the core of the planet? Would the planet be eaten by the black hole? Or would t...
I was thinking of an organism that has evolved to get its energy through nuclear fusion. It has its own fusion rector inside its body that is capable of fusing hydrogen to helium to derive energy....
Sorry if this sounds stupid and/or messed up. So I'm writing this goofy splatter story in which my protagonists are fighting zombies. I'm trying to make the fighting as over-the-top and ridiculou...
A Golem is a creature of Jewish lore, they are living creature created by inanimate objects like clay, stone, hay or wood. They obey their master and will follow their orders. Creating a true golem...
I am creating a fantasy world on a planet entirely separate from our own. Since it is a different world, it makes sense that the food there would be different as well. Some of our fruit is simila...
A common topic in alternate history fiction works is the question what would have happened if a major war had been won by the other side. These usually focus on the events after the war, and the ch...
In most representations of mermaid cities, they either live in implausible magical palaces, or in some more or less elaborate cave systems. Assuming the only difference with our world is the prese...
Humans lay road to gain fast access to distant places until aeroplane is invented, I would presume the mermaids living underwater can make use of the strong water current to get around the ocean qu...
Suppose the mermaids share similar intelligent and technology with us, they also practise performing surgical operation like we do in hospital. Negate the issue of negligent during the operation th...
Unless of course the mermaids can use "super" low frequency like our subs, but wouldn't the quality become poor. How can the mermaids enjoy 4K quality digital TV programmes much like us without lay...
Let's assume that humanity in near future develops an AI capable of solving problems. The AI hardware/ software was placed in an underground bunker (solid walls, Faraday cage, no tools to manipulat...
Whales and dolphins surely do not have ears similar to ours and yet they can pick up ultrasound underwater without fear of water pressure damaging the eardrum. Any idea how the mermaids with ears l...
Let's use the sea turtle and the terrapin as an example, need I say more? I used terrapin because like the mermaid which is half fish and half girl so a terrapin would serve as an excellent example...
I must admit this legendary or mythical creature is really fascinating and I am talking about the half fish half woman. I know most fish have the ability to control buoyancy as they can easily mov...
I'm making a world with magic and most if not all tech will run on mana. I have airships in this world but I'm having a hard time deciding how large across the world should be. I want - even with a...
I'm curious about the impact of having a moon composed primarily of a material with a strong optical property: calcite, diamond, glass or something else similar. Would the traditional spherical sha...
