Inspired (loosely) by societies like the Gunditjmara and natives of the Pacific Northwest, I always have envisioned a system of aquaculture for one of my concultures, though agricultural studies a...
QUESTION I'd like a nation in the world I'm working on to be able to transport natural gas and hydrogen, for fuel and possibly ballooning. Natural gas pipelines and cylinders were first invented i...
The title says it all. How would one go about creating a planet with aliens that have medieval grade technology (windmills and carts and stuff.) No high level technology. However, I want the aliens...
In the fiction, A Song of Ice and Fire/Game of Thrones, one high castle in the mountains, the Eyrie, has so-called sky cells. Those cells are left open to the cold sky. The Eyrie is 600 foot/180 m...
Inspired by this question from yesterday. Solar flares can give off a large amount of radiation, but on Earth this is typically absorbed before it reaches anywhere but the poles, and even then on...
I has this idea for quite a while. I searched for information on the internet but I could see no reference. All searches gave results on the same idea but the effect was not what I'm looking for. ...
My question is the following: How could I design and/or justify a habitable planet that is 80,000 km in circumference? The planet should: Be habitable Have a gravity similar to earth's Have act...
What existing material (e.g. 410 steel, no unobtanium) and what thickness should the ribcage of a creature (of humanoid size and shape, let's say it's a genetically-engineered human) have, to survi...
[![enter image description here][5]][5] Model Lightcraft under laser power While sadly the funding for this research has not been forthcoming, there have been proof of principle flights and ope...
In this world, the continents never split off from each other. They stayed connected into the one giant landmass called Pangea. Humanity developed on this supercontinent, separated by landmarks ins...
Background: I am working on a super soldier transhuman/posthuman concept for my fictional world. It takes the base human genome then uses genetic engineering to augment, delete, enhance, add, and ...
Considering a civilization that was here far before everything we know of, lets say around time of Gilgamesh. Warm climate, almost no winters, near the ocean with enough rivers, and people being ab...
Some of what I read in How could a 4D organism influence events in our world made me think in a different direction about a question I asked before. I'm trying to create a large sphere shaped fiel...
The idea is in a world with 2x the gravity (which follows from 2x the size), gravity would have less an impact in the oceans. Does that follow?
What would cause a place to be always misty? It is in a Fantasy setting, but I am looking for a feasible explanation.
I am creating a board game that requires an underground cavern world, with huge pipes that pump air for the civilization living there. The underground region is at about 35-40 degrees north latitud...
Let us develop an industrial electric motor from first principles. Alessandro Volta developed a battery whose ingredients were copper, zinc, seawater, and imagination. These ingredients have been ...
I was wondering if two bodies could be physically connected to each other such as the ones in the art I have attached. Is there any realism to it? Original art by Dave Melvin
I'm looking for a science based answer based on current technology. Given that we do commit some small amount of resources and time to searching for stellar objects, with our current technology, ho...
I'm looking into the destructive power of a 5km asteroid strike, a bit smaller than the k-Pg event. How does the angle of the strike affect the destructive capability of a land-based impact. For e...
Is there a way to induce a solar flare / coronal mass ejection (CME)? For instance, could a very tight glob of charged particles reconfigure the the Sun's corona leading to this type of event? Is ...
While pondering "Can radioactive moon affect life on a planet?", I got to wondering about plants that send out a tight beam of ionizing radiation. What kind of evolutionary pressure might lead to s...
This article references breaking ice through resonance, but is not specific enough for my case: Resonance method of ice destruction I have a situation where I would like a robot character to break...
Let's suppose that there is a canyon, several hundred kilometers in length, stretching from Leipzig to Geneva and reaching the depth of 30 kilometers. It is up to 60 kilometers wide, cutting throug...
Let us say that someone is 10 times faster at thinking or reacting than the quickest human, assume that they can survive these feats and their muscles can perform them and their senses detect them....
