I'm working on a computer program which generates realistic planets for worldbuilding purposes. I've run into an issue with calculating my planets heat loss. While radiogenic and tidal heat generat...
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...
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...
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...
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 ...
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'm building a S-Type binary system where the primary star is a black hole. Yet the system formed as a O + K-Spectral class binary and the 20 solar-mass O giant went nova 2,7 myr after both the sta...
In the far future the posthuman successors of mankind have disassembled the stars and live on ultra slow and ultra efficient solar system sized computers, Matrioshka Brains. The last enemy of intel...
Fire is certainly high up on the top ten list of mankinds most useful inventions. It allows for a more efficient utilisation of nutriants, is the basis of chemistry and the material sciences, allow...
I seek to build a habitable moon of a giant planet, thus I looked at the Rouche Limit Equation to figure out how to get the biggest possible Hill Sphere for my moon to exist in. $r_H = a(1-e)\sqrt...
How do I calculate the thickness of the upper ice layer on cold ocean worlds like Europa, Enceladus, and Ganymede? I'm asking this for a programm I'm currently writing. The given/known quantities ...
My alien race is supposed to have the ability to communicate a lot of information extremely fast, more akin to uploading something to your partner's mind than telling him. This should happen via si...
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...
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 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...
I´m building a hard-sifi setting and want to use Stellasers (abbreviation for stellar laser) to provide thrust and power to interstellar vessels. This part one is only concerned with the construct...
While building my sifi world I dug into ftl-travel and encountered these mean bullies, causality and relativity. They told me I can't have faster than light travel, because effect can't precede cau...
