Okay, so humans are finally transitioning to a space-colonial society. We sent ships out, colonize worlds, etc... We aren't really in the business of sending multigenerational ships. Instead we use...
It's the year 2050, and you're the planner for a manned mission to Pluto - New New Horizons. The mission will take 5 years round trip, and there are 40 members of the crew. What's the most effici...
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...
In the near future on our own planet of Earth, an odd plague has descended from space. It affects glass. Any glass whether natural or man-made turns into powder. The chemical elements are the same...
I've been inspired to ask this question based off of my answer, and the resulting discussion, to this question: Why would a species of intelligent parthenogenetics invent males? However, this is a...
Rules: No magic Eat, drink, and breathe air (mammal/reptile(amphibian ok)) Intelligent life form (no jellyfish or single-celled organisms) No artificial hearts (unless really ingenious, no swappi...
We have modern humans found in a near future, first world country on Earth. The primary technological advancements are in the form of extremely cheap and fast genome sequencing ($10USD/genome) and...
Let us assume that we have a moon with a reasonable iron core enough that it can retain atmosphere, (as per this question), now let us further assume that the people who settle on the moon are shor...
A top secret organization is planning to introduce a New World Order and replaces every human being (homo sapiens sapiens) with the evolved form of sub species of homo sapiens. Meaning we are sub s...

Many of the intelligent species on Earth, including us humans, are predatory. One of the reasons for this is the nutrient content of meat; a pound of meat is very calorie and nutrient rich especial...

Caveat: No cold fusion! Questions Q1: Where can my dragon source for nuclear energy on Earth set in medieval age and how does it convert this energy for fight or flight? Difficulty:âš Q2: How ...
Upon asking this question, I have learned why we can have nuclear powered ships, but not aircraft. The reason is because the shielding needed for the nuclear reactor is simply too heavy for the pow...
I am trying to build a planetary system with a maximum number of earth/near earth like planets/moons. What would the maximum number of possible earth like planets be? I am assuming that some woul...
An earlier question here concerning a cube-shaped planet got me thinking. Suppose an artificial world-sized engineering project as described in this answer The K-II civilization that built it ...
I am writing a science fiction movie script and a planet idea came to me a few weeks ago: A planet with equatorial icecaps and polar jungles. As interesting and intriguing as this is to think about...
I'm trying to make a world that human sex ratio is 2:8 (male:female). Most of the females are homosexual, and male is not necessary for reproduction. I thought it was easy at first, just say that t...
