Question	—	Lifeform - resistant to gunfire but vulnerable to melee Is there a plausible makeup for a lifeform which is highly resistant to even very advanced firearms (or any ranged weaponry for that matter), but can be injured more readily (albeit still a major feat) by close-ranged machinery/arms? This could be a result of the materials the lifeforms consists of,... (more)	—	about 9 years ago
Question	—	How would interplanetary transits take place with a "space compressing" system? I have a fictional technology in my world that involves being able to create "tubes of compressed space" -- essentially, you have two stations and a (straight or curved) line of space between them that take much less time to traverse in distance. I'm interested in figuring out how to integrate this ... (more)	—	over 9 years ago
Question	—	Life on a Venusian world? I define "Venusian world" to be high pressure, thick atmosphere, and high temperatures. Assume the atmosphere is similar to Venus, but whatever gets the same effect and supports life is fine. I'm envisioning a six-limbed sentient species that's nearly blind and uses sonar to "see", and a primarily f... (more)	—	over 9 years ago
Question	—	How to avert AI. as a main player in the future? it's me again :) With the help of the fine people of this place I have been able to find solution for a number of problems and come up with compelling technologies. One question keep bugging me, however: How do I ensure, that people / people's skill are still the most relevant in space based comba... (more)	—	over 9 years ago
Question	—	How to avoid 'Geary-Syndrome' at relativistic speeds (in space)? Hello again :) My first questions had some wonderful answers, but brought me to the following problem: Although (in my eyes) really dull, the Cpt. Geary series (the Lost Fleet) tends to depict the relativistic issues with space combat quite well (timescales, speed distortion etc.) Is there anything... (more)	—	over 9 years ago
Question	—	Weather on a mini-ringworld/Banks Orbital An Orbital is a miniature ringworld used by the Culture in Iain M. Banks's Culture series. Wikipedia has details on their basic structure, but to simplify, the main difference from a Niven ringworld is that they're much smaller and orbit the sun like a planet instead of encircling it. What I'm inter... (more)	—	over 9 years ago
Question	—	Result of terraforming away the deserts The area of the earth covered by desert is more than 20%. (Sites range from 20-33%, I don't know why the wide range). With technology close to providing zero cost solar (not free, but declining each year by a substantial fraction) the ability to desalinate water and pump it over desert land will be...

Question	—	Could a theoretical cube shaped planet have a moon? I'm inventing a constructed world for a personal exercise in writing, and I was wondering if a theoretical cube shaped planet could have a moon. Is that physically possible? I am going on the assumption that the planet is artificial, and I intend on it being a rogue planet. (more)	—	over 9 years ago
Question	—	What would be required for a completely self sufficient 1 man habitat? For the sake of this question, let's say that there would be a space mission that would send one man on a 40 year journey that will require him to be in a completely self sufficient habitat for the duration of the trip. What would be required for him to be completely self sufficient, and not need any... (more)	—	over 9 years ago
Question	—	Can two civilizations on nearby stars develop independently but be at a similar technological level? One thing that a few science fiction films seem to get wrong: it is extremely unlikely for two civilizations to evolve completely independently and yet be within a few hundred years of each other technologically when they make contact. They are more likely to be millions or billions of years apart. ... (more)	—	over 9 years ago
Question	—	Would co-orbital planets with very similar convergent evolutionary paths be possible? Picture, if you will, four planets sharing the exact same orbit and orbital speed, and separated by exactly same distance from each other. Each planet is the same size and roughly the same gravitational pull and are stable in this arrangement. No satellites and each has no axial tilt. If each world'... (more)	—	over 9 years ago
