A team of alien researchers get bored one day, and decides to conduct an experiment. Seeing that the great ape Homo sapiens sapiens turned out so well ( in terms of technological development and ...
We all know the Kardashev Scale , and the energy output required to get to each level , but what would be the best way to transport those amounts of energy? I have come up with ways to distribute e...
Would a creature similar to semi-aquatic slime mold living on a mostly freshwater planet with shallow seas be able to build technology to the extent that modern humans do? Assuming that each indivi...
How would faster-than-light travel appear through window of a space vessel? All the movies and TV shows like Star Trek and Star Wars seem unrealistic: Star Trek credits: passing stars get bigger...
Gravity in our universe is an attractive force between bodies with mass [citation needed]. This allows matter to coalesce and form all the large scale structures we observe - planets, stars, galaxi...
Okay, so I'm a fiction writer and I love neo-futuristic tech, but when I write I like to be as realistic as possible. One such technology, which I'm thinking of using in a fictional series, is the ...
"How to convince humans to allow a machine take over?" - the answer is, of course, "Gradually." Start with putting one machine into every home, say an AI that is so dumb that it is not really an A...
Follow-up-question to this scenario: ~ 2750 A.D : Quite a few asteroids/celestial bodies have been move to a stable earth orbit and are beeing mined for ressources. I am currently designing the eco...
So let's say that an alien civilization that we have made enemies with decides to use an advanced non-lethal biological weapon on the Earth as a warning. The aliens, while not infamous for any tec...
I am looking for a (at least somewhat) plausible organic matter, which is able to store massive amounts of energy. After reading up on biobatteries and so on, I am aware that I would need something...
In the Hickhiker's Guide to the Galaxy: Mostly Harmless, on the planet NowWhat there are the Boghogs, and their way of communicating is to bite each other very hard on the thigh, so my question is,...
I'm imagining a super-powerful spacefaring race which has the capability to build or modify a star system or even galaxy by moving stars around, but I wonder if it's really feasible. Is it theoret...
What are the challenges involved in such a project? Could you use an asteroid re-direct style mission to do the job, or use some sort of fuel based thrust etc. Please limit answers to those concer...
In a short story that I read (don't have the link, but the short story itself is not relevant to this question), it is set about a millennia from now, where humans have long since made contact with...
What planetary conditions would have to exist to make computers and other complex electronics useless or at least difficult to maintain? Would ionised atmospheric conditions, constant solar flares...
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 f...
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 ...
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 ...
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, ...
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...
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 ringworl...
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 e...
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 assum...
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...
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 t...
