Movies like The Matrix and video games like The Evil Within have popularized the idea of a simulated reality. I'm talking about a human connected to a computer and able to experience similar thing...
Charge-type breath weapon: Creatures with this type shoot singular, high-damage, high-precision "charges" of (insert dragon's element here) that explode upon contact. Examples: Toothless from the m...
Hypothetically speaking, if we would find another planet, the size of Earth, with atmosphere as dense as Earth's atmosphere is, and we would insert (in some hypothetical way) nitrogen, oxygen and C...
Say 200-300 years in the future, humankind has colonized much of the solar system, using a combination of laser thermal drives and solid-core nuclear rockets (fusion never really panned out). Sudd...
So, to quote pterosaur.net: Unlike the wings of birds, the wings of pterosaurs would have tended to change shape under aerodynamic load - something often referred to as 'passive cambering'....
In my understanding bacteria is a simple thing to grow as it requires: a Nutrition concentration at the right Temperature with the right Gaseous concentration at the right pH with additional Ions a...
As conclusion of this question it seems that under a dense atmosphere it would be a good idea to place the main city in mountains. Just there is the inconvenient issue that top of mountains lack fl...
I am designing a fictitious continent, and as part of this I am also designing the prehistoric development of the continent up to the present day. A particular tricky part of this has been that, i...
In my world, Rhino's have mutated and evolved to become larger than elephants. If I wanted to put some sort of dwelling on one (assume its trained) how would I go about doing that? EDIT: The dwel...
This world has gravity, air, and clouds. If humans are weightless yet still has mass, it's gonna take some force to accelerate them. How fast can they move on air, say, if they had fins like divers...
I mean as in a city that is not situated at the bottom of the ocean but is not floating on the surface of it either. What would a plausible size and population size be for this kind of construct? C...
I'd like to know if a climate with snowy and gloomy winters and rainy and cloudy summers is possible. Because the climate of Russia in summer is sunny enough and the Icelandic ones isn't so snowy....
A friend of mine has a race of creatures in her headworld and has been wondering about a biological answer to justify the color of her race's blood even though magic is a bit sprinkled in there. ...
I am developing an alien race whose homeworld is a Dyson sphere planetoid (they used collected planetary and asteroid matter to construct a "hollow planet" around their sun, along with "night" sola...
Trying to figure out how much a 1 foot tall fairy would realistically weigh using these 2 guidelines Fairies are just scaled down humans. Their bones are not hollow because their flight is assist...
The fossil record indicates they evolved far back in their ancestry from something not dissimilar in appearance to a lobe finned fish, but with an extra pair of bilaterally symmetrical fins, though...
To be able to colonize another world, there are some requirements; the harvesting of energy, enough recourses, handling of the environment (pressure, temperature and gravity and so on) and availabi...
The planet in my story, Ser, is actually in reality a moon orbiting a larger body called planet Rea. Ser is located in the L1 Lagrangian point, which means it takes the same amount of time to orbit...
In my world, humans live on a moon of a gas giant that has extreme weather conditions. They also: have crystals that can store energy. possess the ability to make floating islands (on which they...
Mostly what it says on the tin. If a spaceship, let's say about 200 meters long and 100 meters wide (made of modern materials) was approaching Earth and slowing down (say from 100 km/s to 3km/s), h...
Cryostasis, suspended animation, cryo-preservation or cryosleep (the marketing guy's prefer this last one as "Oh yeah, we gonna kill you in a manner we that will hopefully make it possible to reviv...
So, let's say there's a white dwarf star that has recently been born (by recently, let's say about 3 million years ago) Now around that time, a rogue planet, about the same size and mass as earth, ...
We have all heard what too much CO2 can lead to, but so far the biosphere have never been exposed to too low levels of CO2. But what if it did? And please, this topic has nothing to do with the ong...
Have a creature that doesn't really need vitamins or minerals, it only requires energy which goes through a energy-matter conversion to build what it needs. Radioactive materials would be great sou...
Allow me to present Lyr, one of a handful of worlds crafted by artist Chris Wayan: The one detail among a vast many that is important to this question is that its salinity is about 1.5%, roughly...
