In today's Dr McNinja, the Vice President of the US (who is also a wizard) detonated all of Russia's nuclear weapons on the edge of space at once: Copyright belongs to Christopher Hastings, 2015....
Imagine a world with a dead core, like Mars, but covered in water. This world has managed to hold on to its atmosphere and quite a bit of its water as well. I'm sure the prodigious life there would...
In a world in which dragons (as animals, minus magical associations) existed, what natural defense mechanisms might other animals or plants evolve in response? How would a creature as devastating ...
I am sure most of you have seen Star Wars. In Episode IV: The Empire Strikes Back our heroes travel to Bespin, a gas planet with a habitable zone to refuel at the floating cloud city. Well of cou...
Let's assume a planet like ours, same size and same conditions. My characters live at approximately 60° North, in a boreal forest, with a climate much like the Nordic countries in Europe. They are...
For 10,000 years since Beringia, the bridge connecting Asia to North America, had vanished, the Asian and Native American races show great distinction. But if Beringia has persisted to this day, c...
In this scenario, corals, sponges and bryozoans have been extinct for 65 million years. In their place as reefbuilders are echinoderms, bivalves, barnacles and worms of the infraclass canalipalpat...
I've been interested in binary systems lately, and I was recently wondering what Earth would be like if it was in a binary orbit with another Earth-like planet. Both planets exhibit the following ...
It would be useful for a story I'm working on to color the world or various dominant parts of it red. I'm trying to look into the following alternatives, but am open to further suggestions. Essenti...
In my alternate Earths, the plant class Ginkgoopsida has retained its prehistoric diversity, unlike back home, in which only Ginkgo biloba remains. In order for that diversity to be possible in th...
Inevitably, we will be colonizing and impacting other planetary bodies, whether for establishing life or drilling/mining. Today, you can expect on Earth there will be environmental requirements fo...
I'm trying to figure out if a certain city, with these characteristics, is possible, geographically: Assume the city's the size of Renaissance London... With Renaissance London technology Doesn't...
Background We all know that our species evolve during and after the last ice age, (or is it sufficient to say that they evolve at the end of ice age?). A. Initial Condition Suppose I had another...
I ask this as a basis for a World (in this case Moons) Building I'm doing. I came up with a couple of different problems and some possible solutions to those problems: All of these questions pre...
I am developing a world on this continent: To know the world, I have to know how the weather works. Inside the white line is the continent. The blue arrows denote the flow of water. Up is north,...
Inspired by this comment: What if every animal as large as, or larger than, a ice-age vintage horse, except for those that are acclimated to cold climates, went extinct during the last Ice Age? I...
As part of my world's planetary history, an asteroid impact has delivered a sizable quantity of a previously unknown metal to the planet Earth. By sizable I mean a deposit large enough to sustain a...
I'm currently toying with a post-nuclear apocalypse, with most, if not all, human survivors living in underground bunkers or vaults, and probably away from previous population centers"”my test case...
There are lots of posts speculating about a planet (or whatever) where life evolves intelligence and goes on to produce technology, under different differences lacking something or another that is ...
Linked: What would the conditions on a methane world be like? What would animal life on a methane world look like and how would it evolve? Background: Okay, an intelligent race has evolved on a...

A weird question. But let me define "a world without electricity": It's not that we haven't discovered electricity. But rather, electricity doesn't work anymore. Nothing conducts electricity. El...
I am doing some work within the setting of the Exalted tabletop role-playing game. In broad brush strokes, the defining feature of the world is the five elemental poles: Water (west), Wood (east), ...
Imagine that you lived in this world: The planet has a diameter of 5000 km. The rotation time is the same as the orbital period. And here it comes: the orbital period is 1027 years. The planet's ...
Terraforming is the process of transforming a celestial body to become habitable by Earth-like life. Even when I try to imagine an advanced civilization, the cost, time and complexity to terrafor...
For the sake of this question, let's say that there would be a space mission that would send one man on a 40 year journey that will require him to be in a completely self sufficient habitat for the...
What kind of a scenario would have to occur in order for human beings to seek survival on the sea floor? It could be man made or natural, ice age or heat apocalypse, sudden disaster or gradual coll...
If you want to have a smaller star but you also want to keep your planet in the habitable zone, you need to put the planet closer to the star. This means shorter years. It is also possible to have ...
A group of settlers from a mid-renaissance era have setup an initial settlement along a coastline. Materials for shelter exist and fishing serves as the initial food source. What are the primary ...
