Question	—	Can a planet's axial tilt naturally change a meaningful amount in only 100 years from its current cycle? Could a planet's axial tilt change a meaningful amount (what is needed to make inhospitable biomes even more inhospitable: hotter dry hot desert, colder north) over an extremely short period (100 years), without the interference of technology? To give a little context, I'm building a fantasy world a... (more)	—	almost 7 years ago
Question	—	Dwarfs can live for hundreds of years, but how? (Dermatologists hate them!) From the dawn of fantasy fiction, dwarfs have most often been described roughly in the same way: short and stocky, long beards, can smith stuff, good fighters, can live for hundreds of years aging very slowly after "puberty", heavy drinkers. But now, dermatologists want to know their secret. How ca... (more)	—	almost 7 years ago
Question	—	How could the current model of the Solar System have been recognized and accepted earlier? Many factors in history have contributed to society's taking a long time to accept the heliocentric (= the Earth orbits the Sun) model: the first that come to mind immediately are religion and, more generally, people's instinctive resistance to drastic changes in ideology. While the sphericity of th... (more)	—	almost 7 years ago
Question	—	A ribcage capable of surviving the bite of a Tyrannosaurus Rex What existing material (e.g. 410 steel, no unobtanium) and what thickness should the ribcage of a creature (of humanoid size and shape, let's say it's a genetically-engineered human) have, to survive the bite of a Tyrannosaurus Rex? The bite's strength can be up to 430,000 pounds per square inch in ... (more)	—	almost 7 years ago
Question	—	Could a forest grow near a salt flat? In my world there's a salt flat like Salar de Uyuni in Bolivia (of different size if need be) (source) Is there a chance a medium- to large-sized forest could have grown naturally in the immediate vicinance of the salt flat? What changes to the biome (or to the trees) would be needed, otherwise? ... (more)	—	almost 7 years ago
Question	—	To make a gas giant flammable (Warning: do not try this at home-system) Preamble Hello humans, we need advice. Let's say we have just successfully defeated and killed a Horror From Beyond Reason who happened to be multiple times the size of your planet (what's it called now? Earth?), and wanted to barbecue it (no, we don't wan... (more)	—	almost 7 years ago
Question	—	Could two planets follow the same orbit and never "see" each other? Imagine two identical planets planet A and planet B, orbiting the same star. Is it possible that these two planets follow the exact same "route" as they orbit their sun, but are just distant enough from one another, that their star is effectively always between the two, so that a hypothetical person...
