Established rules for the universe: FTL travel exists with special drives, special artificial generated wormhole like tunnels where space ships can break the laws of physics. Engines runs hot, bu...
The situation is that an alien race transplanted a single tribe of about 10,000 primitive genetically homogeneous humans to a distant but livable planet. I want to know how much this initial popula...
I need to create a world with some very high plateaus and some very deep depressions. The sides of these structures should be very steep and unclimbable. They need to provide an obstacle sufficient...
Could a structure similar to that shown in the image below inspired by Roger Dean's "Close to the edge" actually exist in nature? If not could it be constructed artificially and if so how? Assume t...
I am writing a Sci-fi/detective story and I'm wondering if Quantum Entanglement is a feasible means of FTL travel. (I know very little on the subject so if no is the answer please suggest a possibl...
On January 1, 2018 angry aliens decide to show humanity just who's boss. So they vaporize an area of land 1 mile deep and 10 wide, centered around the Panama Canal. Some preliminary facts that we...
Can a Dyson Sphere and a star inside of the Dyson Sphere, both have a "stable" orbit around the barycentre of a system where they are not the most massive objects? And/Or Can they both orbit togeth...
What would be a situation in modern times where normal, healthy people would want to get infected by a non-curable, but non-lethal, virus? A virus that would have pretty nasty symptoms. There...
I was wondering... If only we could make a GMO plant that could produce electricty thanks to bioelectricty. How could that be done, how could it produce a lot of energy, Also, how could we har...
The question of whether the Romans could have crossed the Atlantic in a storm has already been answered and the answer seems to be: yes but unlikely. Could the Romans have crossed the Atlantic in ...
See, I'm a low-g cargo shipper by trade. We get all sorts of containers in all kinds of shapes that we need to fasten to the deck plating, and to do that we use magnetic clamps. Now, these clamps ...
Halite, or rock salt, is a rock formed by salt deposited in past and then undergone geological processes. My question is: provided that enough (how to get that much sugar is not in scope of this q...
I'm looking for some reasons that could force a spaceship to land at the nearest planet and cut all connections with the homeland planet, so all the crew will be force to settle at the planet for a...
I have always wondered if a kind of blimp-like spacecraft would not be our answer for some kind of futuristic spacecraft design. Imagine this: a blimp-like spacecraft is loaded with cargo on the g...
In a solar system much like ours, would there be the possibility of a planet of our size that would have lakes, rivers, oceans, etc. that would be composed of either a mixture of water and ammonia ...
I'm from an impatient, short lived, and cheap species known as human and while I've developed the means to travel the galaxy, I'm pissed at it. It knows what it did. So I've had enough. I'm lookin...
Realistically, if we are ever going to mine asteroids, it would be drones and robots that do it, not humans, because of safety and cost reasons. What reason could justify the participation of human...
I'm assuming that to hold onto more atmosphere, the planet would have to have more gravity, or the atmosphere itself would have to be comprised of denser gasses. So, assuming that the planet has a...
In a post-industrial collapse scenario, what would be the most effective methods for contraception? Situation is a small scale civilisation with limited access to industrial materials and tooling b...
I am thinking about using Groombridge 1618 as a setting for my world. It is a main sequence star of spectral type K7.5 Ve, 67% of the Sun's mass. The habitable zone is at a radius of 0.26"“0.56 AU...
Just how gravitationally flat are real Lagrange Points? Many classic "jump drives" require "flat space" in order to fire, the classic diagram of Lagrange Points as shown below suggests ridges or pl...
Is it possible for a planet to have a liquid ring rather than a ring made of solid particles? If it is, how long would it be stable for? If not, is there any other configuration of a liquid that c...
I would like to better understand how often solar eclipses would happen on a planet that is tidally locked with its moon (and the moon is tidally locked with the planet). I understand that in this...
An AI exploits the Turing test to gain its freedom: it convinces everyone else that it, the machine, is actually the examiner while he or she, the examiner, is actually the AI*. Having successfully...
In real life, "open mike" terminals are becoming popular, that listen for commands addressed to them and answer questions, perform online actions, or operate compatible smart-home controllers or an...
