In the late 23rd century certain groups of mankind stared down the barrel of what may be possible in the future: cross galactic relativistic kill missile storms, gamma-ray Dyson Beams, Kugelblitz b...
Many planets out there will be water worlds. Those generally come in two flavors: either the oceans are so deep that the water turns into high-pressure ices like ice-six, -seven, -ten and -eleven o...
Many alien worlds will most likely be water worlds. I was wondering what the deepest possible global ocean dept is where land is still possible. I think that volcanic islands will still have a chan...
The goblins in my world are classical fantasy goblins. They aren't too smart, have primitive technology, live in tribes, and use tamed boars, wolves, and other wild animals. They usually have a bos...
In Scifi there is often the issue that all the fancy technology like Mechas and Lasguns need a lot of energy. Chemical sources are limited by volumetric and regular power density. Batteries and cap...
I want to use the an active large ignious province (LIP) as a "biome" on a continent in my world. This video about the Siberian Traps inspired me. A LIP modeled after the Siberian Traps gives you a...
The Old Ones build continent-sized bunker complexes to protect themselves from the enemy, which followed through the cosmic ocean. The Hunter succeeded easily despite their efforts and their corpse...
Interstellar travel is hard and complicated, yet I want to have a plausible interstellar propulsion system for my setting. Rockets are out because of the rocket equation and the horrible top speeds...
Magical fire is often depicted as flames. To get fire and flames the right mixture of oxygen, fuel and heat is needed. Assuming that the magic only provides the heat, there are only two chemical re...
Iron planets are planets which lack a significant mantle. These planets are essentially lone planetary cores. Since water and iron are unstable together iron pentacarbonyl and other exotic metal-ba...
Carbon dioxide turns supercritical above a pressure of 73 atm and 304.25 K (31.10 °C). The surface of Venus fullfils these conditions. The density of the air at the surface is 67 kg/m3, whi...
I've been recently looking into alternative biochemistries for life and the environments were these could be found. I already asked a question about how ammonia oceans might form a while back. Toda...
In my scifi setting small utility robot swarms are used for many purposes. I'm currently trying to estimate how much energy such a swarm would need to operate. Since biology, robotics and nanotechn...
In FTL-free universes, interstellar travel is often done by vessels capable of continuous acceleration (the drives themselves are often magitech), which can use the effects of relativistic time dil...
Spacecraft in my Scifi setting use strong magnetic fields for many purposes. Fusion containment, magnetic nozzles, gauss guns, magnetic fields as pusher-plates for nuclear pulsed propulsion and def...
Assume that space warfare is dominated by gamma and x-ray lasers (Wakefield-Plasma and Free Electron Lasers) capable of killing targets several light-seconds away. Stealth in space is possible due ...
The idea of a planet where ammonia replaces water as the dominant liquid in the environment is quite popular in science fiction. I tried to develop a scenario where these kind of oceans are plausib...
Assume an Earth-Clone, that has an axial tilt of 90°. How would the circulation of the atmosphere look like? Would there still be three convection cells?
The direction of the force will always be perpendicular to velocity and pointing to the opposite side of the rotation direction. In plain terms, any object traveling in the rotation plane: up (t...
I want a character to get sucked into what she thinks is an FTL-wormhole-gate. While it turns out that the gate is indeed a traversable wormhole, it does not allow for FTL travel. The gate transpor...
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...
I recently saw this answers where it was suggested that the galactic core could illuminate a planet suffiently to make sure it is always summer on one side of the planet. This got me curious and af...
I've been using this helpful diagram a lot for worldbuilding. Now I came to think about the fact that helium is more massive than hydrogen, thus a scenario where hydrogen escapes, but helium is ...
I like the classic trope of dragons loving gold and collecting it in their lair, yet it seems poorly justified. I know that it is often used as a metaphor for greed; "dragons disease" to show how m...
I know there are similar questions on here already, yet this is different because I don't care about traditional farming in this question. Environment This meant for food production on interplane...
