Given eggs and sperm, and the means to preserve them for centuries, could an artificially intelligent machine possibly produce its own "children", so to speak? Assume it has everything it and its ...
I read somewhere that the lowest depth for a sustainable underwater habitat is estimated to be three-hundred meters. Any lower and the pressure becomes too great for structures that are currently w...
If there was a supermassive structure built on earth (30km tall, 10km wide/deep tower with slightly slanted faces), what sort of effects would this cause on the surrounding areas? Specifically, wha...
I'm trying to layout a scientifically correct evolution path for the octopus to develop intelligence on the post-human Earth. I'd like to know if it's possible for an octopus mom to choose, or use ...
Humans with a level of technology roughly equal to the present day, not more than a decade or two more advanced (e.g. they might have slightly more efficient rockets, or a more miniaturized comm sy...
Suppose NASA, SpaceX or any other aerospace company has managed to build a technology that allows them to fire a rocket to the moon, from "space". Basically, they have created a huge weather balloo...
Would it be possible to have a cold and remote polar region if the oceans are made of fire? By that, I mean that in the place of water, there exists lava.
Essentially, what would be the most efficient way of causing the Earth's core to cool as much as possible without damaging human civilization in any other way (the outcome can damage it, but not th...
I am looking for information on how the trees and the flora would be in a world with a denser atmosphere and stronger winds. I have read that due to the greater kinetic movement of the wind, that ...
What I'm thinking about is simply an animal,any with a protective bony-like shell covering its eyes. The shell must be openable for clear vision but when closed the animal still has the ability t...
I'm toying with an idea to have a plague sweep across the galaxy in my story. At first I was thinking to have a plague, something similar to the Black Death, devastate populations across the galaxy...
So Chlorine Trifluoride is a very dangerous chemical known to burn through things like concrete and asbestos. It's so bad that the Nazis, THE NAZIS, decided it was too dangerous to use. So I need a...
The context: There is a population of people surviving on a lunar-analogue's surface, descended from the crew of a crashed spaceship. The rest of their society is not relevant to the question, but...
I have a creature (a cat person) that wants to set its own fists/claws on fire, because it attacks via its fists/claws, and is fighting enemies that are fairly flammable. What can this creature do...
So I'm working on a story that at its groundwork has a lot of sciency things, and then has a lot of unsciency things attached to it. The story has an FTL drive which is the good old "fold space, pu...
I've tried researching this question myself, but the only data I can find is over huge timescales, like situations where the continents have reformed back into a Neo-Pangea. I'm not looking for an...
How could complex life like humans of or other animals evolve to exist in temperatures in excess of 100 degrees centigrade. This does not need to be natural as long as it can in theory be achieved ...
I've been thinking of using a binary model (a planet that rotates around two suns) for a possible story. The specific model is a S-type planetary system, where the planet orbits the the primary st...
After I reworked my map, I have a big plain (roughly 1165500 square miles). Can I still credibly divide the plain into different kingdoms and cultures or would a big empire with few cultures inevit...
So here's the picture, an island about the size of Sicily is on its own tectonic plate, it borders three other tectonic plates, it's separating from all of them at the exact same time. This is a f...
After reading this thread from a bit under a year and a half ago about the most cost-effective means of travel on Mars, where one of the answers mentions rail as the best option, I started wonderin...
I have a species of ambush predators that are going to be sentient space-farers one day. But to get them on that path I need them to evolve hands, which will lead to tools, and so on. They come f...
If an organism weighing roughly 20kg existed (same weight as a dog), similar also to the structural composition a dog. How much muscle mass would be required within those legs for it to jump 20m? ...
In a story I have been working on, there is a planet called Ieuclite. I want to have its surface be entirely covered in ice and have the people live in cracks and fissures. But then I thought, what...
Assuming the information in this video by the Cambridge University is correct, Planthoppers can jump as far as a meter. Their size ranges from 1cm in cooler climates to 5cm in the tropics. With ...
