Brown and white dwarf stars are thought to have habitable zones but are very close orbits. Plus these planets will experience strong tidal forces and be tidally locked. But if you have a large Ea...
I need some help with the placement of the cities on a map of one of my continents. I'm not looking for opinions, but more for a reality check on how realistic it is in terms of where things are an...
A normal respiration is: $${\displaystyle C_{6}H_{12}O_{6}+6O_{2}\to 6H_{2}O+6CO_{2}+38ATP}$$ A normal cellular respiration uses O2, so my question is if it's possible to have a respiration with C...
I was told to post this question separately, so here it is. I need help with the geography and climate of my map. Blue circles are ports Gray circles are cities That one brown circle is a town ...
Is possible to have a geothermal plant (not necessary a very powerful one) to work for several millennia without the place where it is built over running out of heat? I found a page (don't remembe...
My creature is a 'chimera', so it is a combination of a few different animals. As a defense (or an offense) mechanism, it can coat itself in a flammable oil and self ignite. I would prefer to refer...
I was thinking of ways to make the human body stronger, so I was wondering why not lift weights with a higher level of gravity, hence my question. I'd like to know if there's some clothes, jewelry...
In a series I remember that a group of people were trying to make a colonization ship and they had a big problem: the air. Ships (like every object) aren't perfect and they have micro fissures in t...
Okay, so admittedly I was going for a title that was a bit more catchy than the actual question, but not by much. On a technical level, the real question is "Feasibility and challenges of why a la...
Long story short, this civilization found very little oil and natural gas in their world (or maybe they ran out of both), but there are huge deposits of amber and special pine trees which produce r...
Assume that Handwavium is a gas many times lighter than Hydrogen. Is it realistic to use this gas to make relatively heavy full-body armor (say, brass) lighter and/or more maneuverable? This seems ...
The setting for my story is a very foggy and windy place. There is a plant that grows on relatively short trees that needs to attract animals to spread its seeds, which are inside its fruit. Becau...
I'm building up a spreadsheet on worldbuilding (Stars, Planets, Moons etc.) and i'm struggling to find an equation, or a group of equations to help me figure out the light received by a planet orbi...
Blinding, amputation and other punitive mutilations have been used effectively in the past; however there are no accounts of deafening, e.g. removal of one's sense of sound, being carried out. How...
Two days ago I asked how we can detect a (really) small black hole. The best answer (to me) was "gamma rays". Since this black hole is relatively close to our planet (a few AUs), this could be a pr...
How Long could an "Eternal" Fire last? At some point there is a fire very spiritually important to a certain people - so important that they build a city around it, and begin developing an empire ...
I've read comics in which someone with pyrokinetic powers was able to block bullets with a sheet of fire. I have three questions How hot would the fire have to be to melt a bullet passing through...
Subangea is a giantic cave that stretches below the surface through endless cavities. From oil oceans to volcanic sinkholes and even upside-down forests, the environment is ever changing from one c...
Where would the Sun and Moon be on a flat Earth? Imagine a world similar to the flat domed depiction of the Earth with a Biblical Firmament all around it. If you don't know what that is, let me e...
Ok, so this is an very odd little question. I've been working out the economy of an industrial age world; figuring the major industries, trade routes, etc. I have a tropical region I was consider...
A mad, egomaniac, scientist has developed a way of extending the natural growth of humans to create an army of 20ft (6 meter) tall soldiers. Physiologically, they are three times the size of norma...
My race of space-going sentients want to weaponise a life form which is explosive in an oxygen-rich environment. To do so, they have access to any planet they care to use, terraforming, and the ab...
An ideal punishment for evil scientists or geniuses would be a judicially mandated, deliberate decrease in intelligence. Let's say that a judge ordered a person's IQ to be decreased from 200 to 110...
So I am working on a concept for a location, wherein a sort of oracle will exist. This oracle will in no way be super natural rather the strange behavior of the oracle (a human for the sake of the...
Once I heard a scientist saying the following: Imagine an ants' nest and all the ants living there perfectly organized, each one with specific duties to perform for the well being of the...
