Carnivorous plants live in nutrient-poor, highly lit habitats, such as bogs or rocks. For example Earth's biggest carnivorous plant, Nepenthes rajah, lives on mountain-tops with high concentration ...
I remember a cartoon about some spy guy. In that cartoon they did mass media by projecting from the surface of the earth to the moon in the night sky. Would that technique be possible? Could an e...
So last year I started writing a post-apocalyptic story, and then realized I had no idea what the world was really like, and quite a few things just didn't seem to make sense. One of the biggest t...
In a story I am working on, I need a scene in which one of the main characters finds himself outside in precarious weather conditions, unable to see unaided much farther out than an armlength or so...
If there are several races with very distinct appearances (e.g. Nordic-pale vs. Arabic-tan skin, red vs. black hair, etc.), how much space / natural barriers do I need between their homelands to ju...
I want to have an upper atmosphere composed of a gas which is lighter than "air" so that my human occupants of a planet can harvest it and use it to fill blimps and hot air balloons. I'm planning ...
Almost all of our terrestrial furniture is designed and depends on gravity. Beds to lie down in, chairs to sit down on, tables to place things on top. None of these would work in a zero-G environme...
I was just wondering what kind of rule changes court layout etc would happen to have a 'basketball' game in a zero-g arena? I'm assuming the most likely thing to stay is a ball and 2 opposing bask...
I'm building a post-apocalyptic setting where the cataclysmic event is a volcanic eruption from Yellowstone that releases a blanket of ash that reaches from California to just before the Midwest. E...
After asking this question, What's the worst natural disaster that could hit New York City in our lifetime, it looks like the most popular answer was a Tsunami. A tsunami, however, from the sources...
Once geological processes have created a landscape a number of factors come into play in order to reshape it. This includes weather and climate effects such as wind, rain and ice reshaping the terr...
*By life, I mean something more complex than microorganisms. Something closer to what we have on Earth. similar to this question: Is it possible for complex life to evolve on planets without oxyg...

So I'm writing a story on a population of lizardmen who have subdued all the human population. Since lizards spend lots of their time soaking in the sun, I'm not sure how should I go for the night...
I put a force field dome over my city. How would that affect the weather inside the city, and outside it? Specification of the city: 10 × 40 km on the surface 1 km in height dome would be 2 to ...
In relation to this question, how could I create a force field dome over that city? Specifications of the city: 10 x 40 km on the surface 1 km in height has a city wall of 100 m all around the ...
Note: This question assumes an earth-like biology. Could a microbe (probably virus) be created that transformed humans into plants? What I mean by this is that the microbe would take human cells, ...
Let's take a world that is based heavily on Elon Musk's specific ideas of Mars colonization, to whit: Launch technology from Earth evolves to be to <$100/lb cost to launch ratio, due to reusab...
First off, let's get definitions out of the way: A "race" here is defined as stable, heritable, phenotypic, clearly visual distinction between large demographic groups living in different geograph...
Would a civilization that is trying to permanently colonize a landless world with no atmosphere (think Europa's sea) be able to do so? Permanence matters - it means you can't simply build domes th...
I'm trying to design a food chain. For the sake of argument lets say it's based on flying creatures over a particular mountain range. Sun Plants/Fungus etc Tiny Insects Small Birds Hawks Large Ape...
In many stories we hear about people whose genetic structure is modified after they're born (Spider-man, The Fantastic 4 and practically any other superhero you care to mention). However current sc...
Disclaimer: the overall idea of the world as presented is basically lifted from Strugatsky Brothers "Inhabited Island". The details of the question are for a derivative work in that universe. Imag...
I was wondering what would happen if there was a planet with a "shell" of stone entirely surrounding it (not connected, just held in place by gravity), with a few holes all the way through the oute...
If I want an Earth-like planet, what kind of star can I use to achieve that ? According to the Harvard stellar classification, our Sun is a G-class star. The best would be to have: Temperature ...
