Much effort went into creating sims, uploaded personalities obtained through destructive scanning of a person's brain. These efforts have largely been successful. Whilst officially banned in the ...
Earth, far future: We built multi generation ship which can get 20 000 people to another solar system in next 20 generations (600 years) For scope of this question assume that ship itself is well ...
Would it be possible for a fully modern civilization (i.e. quite like our own, perhaps slightly more advanced, with near-future tech) to arise on an Earth-like planet devoid of uranium, plutonium, ...
In the bible, one of Jesus's earliest miracles was turning jugs of water into wine. Let's assume that I need some wine - and it doesn't have to be good wine - but I need some wine for my guest. I h...
Some Details Suppose an Earth-like world with the following changes: Atmosphere: 67% nitrogen, 31% oxygen, 2% other Average surface temperature: 16.7° C (62° F) Day/night cycle: 20 hours Gravi...
With today's technology could mankind create a system of rings similar to Saturn composed of different masses of water particles and silicate minerals that would freeze? How could mankind accomplis...
I was thinking of a scenario in which a population of snakes gets stranded on an island in which they are literally the only animals. This hypothetical island does not even have insects for the sn...
This is a followup to my previous question concerning the potential orbits. I've decided on a barycenter with each body in its own orbit--the primary planet having the center orbit, the first moon ...
Specifically, I was wondering if a core of magnitite or some such other magnetic metal could be a planet's core. This is in relation to my other question, found here: Can airborne floating/flying...
When I asked my previous question about love on multi generation ship, I left blank the where are the people going. Simply because I do not know. Now I am in search of software which would ease s...
A character of my story is in the following situation: He is in the middle of a forest and has lost his way out. He wants to be sure to keep straight on and not to move in a circle. He has no co...
Would it be possible for a planet with surface conditions suitable for humans landing on it to have a very strong magnetic field, with field strengths on the planet's surface similar to the surface...
I'm sure that this has been asked before, but I need floating islands for a fiction story I'm writing. It takes place 5000 years after a catastrophic event (on a vaguely earth-like planet populated...
Rogue planets are generally not to healthy for us humans to live on. No permanent source of heat or light means that generally they are a pretty cold place. Plenty of other problems arise too, but ...
Ordinary granite is a tough rock"”the toughest on planet Earth"”but it still cracks easily, exposing it to the wrath of erosion. But the granite that makes up the Yosemite landscape is different. ...
So I'm trying to make an orbital city, kind of like the ISS, but on a much bigger scale. And against all logic and reason, I want there to be balconies. Like, where someone can just step outside, w...
The planet I'm working with has two different moons, both around the same size (3/4ths that of the main planet). Is it possible for the planet to support the orbit of these moons, especially with t...
So, according to Other blood colors it is entirely possible for other blood colours to evolve based on what base they use, but why? What would be the benefits of these different bases? What purpose...
First, for scale, this map is about the size of the continental US. Assume that the mountains are about the size of the Rockies. These mountains are jagged on the outer edge, and more sloping on th...
In previous questions on this topic, I've devised a genetically-diverse creature that uses a cold fusion internal engine to provide tremendous amounts of short-term (sprint) energy. However, there...
I know, it sounds like a geek swearing at Windows 8 on his work-owned computer. But actually I was just reading Peter Clines (Fold and then had to order 14 for instant delivery), and when I got to...
Assumptions Space travel is hard. Interstellar travel takes a long time. Chances for a successful trip and colony becoming self-sustaining are not considered super high. Therefore, each colony ...
Solar wind density is very low even at Venus it is only 10 or so H+ ions per cm$^3$ but it is moving at a brisk clip of 400 km/s for the slow wind and 750 or so for the fast wind. So (feel free to ...
Because who needs a space craft? Picture this: While performing a routine spacewalk, outside your small, 1- man space pod, a fault in the propulsion system controls causes the pod to explode, laun...
This question is almost exactly like Could plants develop intelligence, but now I wonder (how) could plant life develop sentience, to the point where it becomes as intelligent as humans? Is a brain...
