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 ...
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 ...
I'll address storage of antimatter, because that is the one thing in your question humans have done successfully so far. While we may someday build an antimatter-based propulsion device, it's a way...
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...
*By complex life, I mean something more complex than microorganisms. Something closer to what we have on Earth. Similar to this question: Is it possible for life to evolve on planets without water...

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...
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...
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...
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...
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 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 ...
One way would be to do something similar to how Michael Moorcock ended the world of Melnibone' and the Young Kingdoms at the end of Stormbringer - and in a battle of the gods, it really doesn't mat...
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...
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...
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...
A plant chasing humans would be unrealistic, but I think a plant generating a trap for human-sized animals could be possible in principle, given the right circumstances (maybe it evolved from one e...
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...
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 ...
Giant winged beasts such as the Roc and the western dragon feature strongly in mythology. Is there a maximum size on a biological winged flying creature? How would an atmosphere different from Ea...

As the title suggests, what happens to a planet geologically and geographically over time? This question came to mind from the many sessions of Civilization I have played where when you set up a c...
I'm interested in writing a story about inhabitants of a permanent base on Mars, a few decades after all life on earth has (presumably) been wiped out. Preferably, I'd like them to still be there, ...
