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...
For a SF story I'm wondering how thick a planet's rings can be? When viewed from the inside, can the ring material be so dense that visibility would only be a couple of meters? What would it take t...
I created the above illustration to help convey my meaning, here is what everything means so that you can read it effectively: E = Earth V = Venus M = Mars The dots in the lower left hand cor...
I want to write about a planet that has a high average temperature, but low enough to be comfortable. Just because of curiosity, I would also like to know the lowest comfortable. Additional Info:...
The only such media I've seen is Fallout, which is obviously highly fantastical. I mean, they mutant animals and irradiated zombies running around! But realistically, is there anyway that life cou...
I am creating a world in which a civilization has achieved advanced spaceflight and has begone colonizing other planets in their solar system that is similar to ours, but with more planets. However...
I'm aware that 'tatooine' worlds don't make good habits for planets, normally. From what I've read, either a planet has to orbit one star really closely, or orbit both stars from a really long dist...
So this planet enters our solar system from the 'south' pole at 30 kilometers per second. A bit faster than the first Interstellar asteroid ever discovered. Of course, it plunges into the Sun's ph...
I was not entirely sure how to word the title question, so allow me to put my question into more detail here: Suppose there was a planet with just the right conditions to allow humans to live ther...
Inspired by this question, so credit to them for the core idea. How might a slow fire energy weapon reliably neutralize its target? Here are some details about the precise design I had in mind: I...
My story is based on a Glacial Climate setting or an Ice Age. However the transition is gradual and humanity was given some time to adapt. The transition began in our real-world technological equiv...
Background: I'm toying with the idea of an alternate Earth that never developed wireless technologies. Radio transmitters, Wi-Fi, etc... were never invented, meaning that light-speed communication ...
Elves and human share many similarities, from body type to the ability to perform magic. However, elves retain a slim, lean build throughout their life, and are incapable of becoming obese. The big...
In my world, a scientist and engineer by the name of Guoliang Guan successfully uproots and moves a quarter of a million tons of habitat, industry, miscellaneous chemicals, storage containers, rock...
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...
Dateline: 2067 Setting: A research base at the bottom of the Marianas Trench Depth: 10,000 meters. Mission Duration: Thirty days A research base lies at the bottom of the Marianas Trench, housi...
I'm thinking of a world where the earth's moon is densely crowded with dark materials. Solar power plants, dark buildings covered with radiation shielding, large dark open pit mines etc. Imagine th...
In this world, a planet with very dense vegetation (earth-tropical-forest-like) and silica containing soil was attacked by spaceships which fired very high energy laser beams across the planet's en...
From pictures I've seen, all rocky planets in our solar system are some shade of grey, brown, and red. Ignoring stuff like atmosphere and oceans and plant life of course. I was thinking of a world...
I'm working on a story that has several worlds but I focus only two of them now. World A is our present, world B is a fantasy-ish one which is very similar to ours but evolution has been different ...
Enter Iaeptus - A million man mission born on a fleet of ten thousand ship to the outer solar system. Their commander : Minevera, a brain-in-a-vat super computer. With a weight of 5 tons, a neuron ...
In my world ... Actually, in every hard sci-fi world with casual interplanetary travel, the G-force involved in acceleration would becomes so high that no unmodified human being could realistically...
While trying to figure out a way that individuals could own spacecraft in my sci-fi setting without having access to things that could double as weapons of mass destruction, I settled on the widesp...
Obligatory Premise In the year 2201, Diego OfeAde has been in control of Mars for 50 years. He has moved mankind into Valles Marineris and his aggressive population expansion program has seen t...
In my world, all terrestrial bodies in the solar-system of over 900 km size have a significant human presence. Earth-moon Travel is as common as an interstate road trip, and Interplanetary travel i...
