I was looking through a bunch of different ways we can shape a map of the Earth and it got me thinking. We map out planet as a stretched rectangle with NSEW as Up Down Right Left, with the Equator ...
The organisms in the oxygen based ecosystem we have today is perfectly adapted to each other. The ocean is filled with water, and on land it falls from the sky. Plants, algae and cyanobacteria spli...
First let me say that I know almost nothing but the basics about nuclear fission. I know more about nano robotics but I've got no degree in the matter, just a rather in depth curiosity and a lot of...
Assume that a species of bigfoot-type animal/person exists. Most of this also applies to ogres or trolls, whatever big dumb giants your particular setting has. My world's specs: They range 7-10 f...
this video surprisingly has some similar properties i try to make and better at explaining the science properties (without me knowing the science stuff before) warning!! don't watch the video when...
Creating a map of Koppen climate zones for a very Earth-like world is quite easy, with the right instructions. However, what if the climate is several degrees cooler? Do I simply shift all the clim...
(maybe this should be part of the "anatomically correct" series. If so, feel free to edit accordingly, as I don't know how to add it to that list) Could a roughly human sized, human weight, biped...
This is strictly Earth based. Would it be possible for a society to develop their own civilization underwater (nothing fantastical like Aquaman or whatever, but more of a grimy, hardscrabble existe...
Fact 1: The cause of a sunset is from the angle of the sunlight, because the amount of scattering increases as the light passes through more and more of the atmosphere. Fact 2: Higher frequency ...
If people were attempting to build a space station beyond the Hill Sphere, (outside of the area where Earth's gravity dominates), and wanted to mine the raw materials for the station from dwarf pla...
I see that asteroid mining had already been extensively discussed in the context of today's technology (Ex. Is Asteroid Harvesting economic?) and the answer is a definitive "No" - it's not economic...
I'm looking to know about minerals that space miners can extract from other planet surfaces or directly from asteroids. Something that Earth as a planet may need in the future.
I'm thinking about underground humanoid cvilisation without knowledge about outside world and how could they have eyes? Known fact is that a lot of animal living in dark don't need eyes. (cave or...
The Ozoa are a peculiar race. They are native to a large gas giant similar to Saturn and physically look similar to what we would call "jellyfish". Within their "head" the Ozoa contain a lifting ga...
WARNING PROBABLY CONTAINS DISGUSTING STUFF So base of my previous question about will there complication to the body, especially the guts, if basically a single Senzu bean make a person never need...
I was certain somebody would have asked this before, but after scrolling through the Similar questions list I couldn't find any duplicates. For this question, let's say that an asteroid or comet s...
I am working on a story where I will take the geography of our world but install new peoples, cultures and histories. This will likely include fantastical elements as well as mundane. In working ...
One of my main problems when it comes to drawing maps is how landmasses get distorted at different points. One of the continents in my story stretches almost to the north pole, but it looked very d...
I have only encountered the "Sonic Boom" a couple of times in my life, once when I was lucky enough to watch Concorde fly over my town in the late 70's. In a story I'm writing someone claims to ha...
In my pre-electricity world, fast communication is achieved by means of lighthouses, each being able to direct strong and precise beams of light towards distantly visible lighthouses. However a pr...
I have seen Isaac Arthurs video of O'Neill cylinders and read through many descriptions, but it still is not clear to me how exaclty the two counter-rotating cylinders are placed in regard to anoth...
For some reason, all the nations in the world have banded together. Their goal? Go to the Moon. Their budget? As much as the planet and humans can throw at it. How fast could we build a reliable a...
I've quite a few alien species that utilize a non-food-based metabolism (one of them being nuclear power). Does a species that has a metabolism not based-on plants or meat (such as using nuclear ...
There's an important aspect of my headworld involving volcanoes which I planned many years ago. Recently I revisited this concept to refine it further, only to run into a few questions that I've b...
I'm making a Region of a planet with very high humidity, mostly covered in fog at ground level. I am open to having seasonal changes and would like there to be a few sunny days lets say 1 out of 15...
