Question	—	What would it feel like on the surface of a planet while it collides with another planet? Let's say that something horrible has happened and a Mars-sized planet is knocked out of orbit and is hurtling towards an Earth-sized planet. How much time will they have? How will this affect the inhabited planet? Obviously the impact itself means the end of life on that world, but this is happenin... (more)	—	about 8 years ago
Question	—	Bailing out of a train A group of robbers in the Old West (of America) are planning a daring heist. They intend to rob a newly commissioned train on its maiden trip across the country. This train will have an upper-class crowd celebrating the trip, along with a great deal of private security. The plan is to pose as waiter... (more)	—	over 8 years ago
Question	—	Fusion Power and Plasma Propulsion In the classic idea of a Tokamak Fusion Reactor, plasma races around an electromagnetic track. Is it plausible to "spin" off some of this rapidly moving plasma and direct it to nozzles for use in propulsion? Or is it more reasonable to generate plasma at the engine itself, as in the Vasimr Drive. (more)	—	almost 9 years ago
Question	—	Deadly, Heavier than Air Gas In a given fantasy world, I need a deadly (yet not magical) gas that will naturally pool in low depressions and valleys. The level of magic is not high, so I'd like it to be an actual chemical that an astute reader/player might be able to identify. Ideally, it should be mostly opaque in large quant...

Question	—	Dietary Requirements of Giant Spiders Giant Spiders are a traditional element of fantasy worlds. They prey upon most human's primal fears, and are easy to make as evil as possible. (Note: Not to scale) But are they actually plausible? What kind of environment would be required to sustain a sizable population of giant spiders? What c... (more)	—	over 9 years ago
Question	—	What do we get if we eat the moon? Imagine we have a machine that can consume celestial bodies, breaking them down into component elements and storing them in big bins somewhere. If we fed that machine a moon, what would wind up in those bins? Assume: Earth's moon. We do not concern ourselves with the planet the moon is orbiting. I... (more)	—	over 9 years ago
Question	—	How big would a pair of wings need to be to allow an adult human to fly in a given environment? Lets indulge in a bit of Mad Science, here. Assuming the world described here: Making the Enterprise Fly (60% of earth's gravity, 50% denser atmosphere) what is the wingspan needed to allow an average adult human to fly? Assume feathery wings, and that the resulting winged human needs to be able to... (more)	—	over 9 years ago
Question	—	Making the Enterprise Fly No, not that one. This one. I want to see the USS Enterprise fly, but I'm curious how it would be accomplished in any realistic fashion. Now, the world I'm building that needs a flying Enterprise has some advantages that might help us. Gravity is at 0.6 Earth Standard, and the atmosphere is consi... (more)	—	over 9 years ago
