[Question] [ As we all know the Earth is flat. Once upon a time a group of explorers set off with the idea of proving that the world was round and that there was a route to the spice islands the other way, but the few survivors came back screaming about seeing ships falling off the edge of the world and something abo...
[Question] [ While the person of the king may go on trips or lead armies in battle, it is another thing to have an itinerant government. In the earliest feudal kingdoms of Europe, the entire apparatus of government moved with the monarchs. When Charlemagne was the Holy Roman Emperor, he had no official capitol. Many...
[Question] [ My colonizing business found a small planet with about 0.8G.

[Question] [ What are the requirements for mass distribution and body positioning that would enable a large creature (say, a panther) to walk on water (and still be able to dive down and swim if it wanted?) This should extend to hunting (chasing fish on the surface and then diving through the water to catch it) to wa...
[Question] [ I'm building an alien world for an artistic project. The world circles an m-dwarf star, and so the flora have evolved to photosynthesize longer wavelengths of light than on Earth, primarily in the near infra-red. **I've come up with an interesting symbiotic relationship, however I don't know if its scien...
[Question] [ I am writing a sci-fi novel in which humanity has colonized a majority of the solar system, and a few minor colonies on nearby stars.

[Question] [ I understand that there is an on-line site, named Impact Earth!, that allows us to calculate the damage caused by an impact of an asteroid using some parameters. In my novel, I have an impact from a solid rock with approximately 500 meters in diameter on the ocean bed, free falling at a 90º angle. Troubl...
[Question] [ Looking at a race based on Hobbits or Halflings, and I am wondering about the average weight and if that is affected by denser muscle mass (than human children of the same height), and the realism of their strength. Using D&D as my guide, but it seems...high for something that's supposed to weigh only 30...
[Question] [ Assume we have a sentient race that is both non-dimorphic insofar as males and females have no non-cosmetic secondary sexual traits, simply different reproductive organs and perhaps different cosmetic features, and *oviparous*, i.e. laying already-internally-fertilized eggs. (For instance, this is one po...
[Question] [ (New here!) As I am setting up the astronomic framework of my new world, I have real issues finding information, formulas and calculators to get the actual size (diameter or radius) or apparent size (disk size) of my moons.

[Question] [ The temperature, pressure and radiation are all not optimum on Mars for life. But if the pressure were several fold higher (20-30 mbar instead 6 mbar), the temperature 5C higher, and with less radiation could we manage an open air lake seeded with all the life needed and fish? This could provide food for...
[Question] [ I read a story about a Mars war. There was a lot of shooting by the Martians, which made me think about insurgents weapons on Mars. It makes no sense to me for all these guns to be accessible. Not having hunting or armies beyond perhaps a police force, they wouldn't have much in the way of guns. So what ...
[Question] [ **Disclaimer** I've had a look and the other Large Turtle posts seems to be world based or assuming the turtle already exists. **Question** My question is how large could an island sized turtle reasonably get and what ecology would reasonably be needed, eg large amounts of surface algae/plant life. **Wha...

[Question] [ I'm wondering if, using enough neodymium magnets (dont worry where the material is coming from) in a low martian orbit, could you produce a powerful enough magnetic field to protect the atmosphere from burning away? How would this impact interplanetary travel? How much maintenance would it take per decad...
[Question] [ Lately, I've been looking at Google images of "centaur skeleton", but they don't look that convincing to me. The problem is whether or not the last human lumbar vertebra would be the right size to fit on the first equine thoracic vertebra as easily as clicking on a strap. In a sci-fi horror, a mad scient...
[Question] [ So I have this idea for a creature that has a loop arch on its face. My only explanation for why is because it needs extra surface area for its sense of smell. But then I wondered what would warrant the need for so much surface area just to smell? Would dense air require it because there's more air to so...

[Question] [ I'm running a D&D campaign and am using a modified map of Venus for it that shows what Venus would look like with similar amounts of water to Earth. The problem I'm running into is mapping the ocean currents around the equator at this point of the map where a centrally based gulf has land on either side ...
[Question] [ For my world I would need a really large swamp (or similar kind of wetland). It should be about 200km in diameter, which should be quite possible given a large enough flat terrain and enough rain. The problem is that this environment needs to be completely isolated from the mainland: my small humanoids ...
[Question] [ I was recently redesigning some mostly hominid Aliens I designed a long time back in high school and felt were a little lackluster, and since they were already Tall, Wiry, and vaguely Shambolic-Looking before, I came up with the idea of giving them greater flexibility and strength by giving them a spine ...
[Question] [ I'm aware that variants of this question have been discussed before (such as "how to build a self-sustaining medieval city?"), but my question comes at the problem from a slightly different angle.

[Question] [ I make no assumptions to the nature of this planet. There are high chances it does not have an atmosphere or a lithosphere. But in a planet that shows a high level of radioactive activity, would it be advisable to probe for life, or is it improbable? Either way, why? How would we go about detecting life ...
[Question] [ It's typically regarded that life needs liquids of some kind to evolve. But liquid is just a state where molecules can move around freely in order to interact with other molecules instead of being packed tightly in the solid state. What if this "liquidity" was based on nano-particles of at least partiall...
