This question was stimulated by the question How would an aquatic race develop computers?. The answers obviously were based on the aquatic civilization being earth based, but what about a totally ...
Consider a dual-star system, with the distances between S (larger star) and J (smaller star) similar to Sun"“Jupiter. A planet P rotates around J on a 90-degree ecliptic and is Earth-like otherwise...
Would it be possible for a creature to have a nervous system working at 250 volts? What kind of physiology would it need to sustain that? Could you use that creature as a power source, to power a ...
I had in mind a sci-fi setting where humans have begun terraforming nearby planets without the benefit of faster-than-light travel. For example, Wikipedia lists a handful of terrestrial planets wit...
Let's see if I can explain my thoughts accurately with an example. Imagine that a mad scientist decides to kidnap a few men and women and decides, just for fun, to switch their sexual organs, but ...
Giant Spiders are a traditional element of fantasy worlds. They prey upon most human's primal fears, and are easy to make as evil as possible. (Note: Not to scale) But are they actually plausib...
I've been thinking about a cyberpunk universe where nanobots are a universal force capable of achieving many things, examples include: Biological and medical modifications of the human body Const...
Real x-ray vision, the ability to (at least) detect X-rays as a 'visible' light (or any other detection system) seems it would be very problematic. X-Rays are a high energy form of electromagnetic ...
A modern day Earth nation is at war with another. That other nation is extremely advanced but they are also pacifists. Instead of killing peoples their gun rounds and shells have the effect of worm...
A group of behaviorally modern humans was cut off from the rest of the earth-like planet. At the time of the separation, humankind had reached a technology level including cattle ranches, brass, wr...
This is for a video game project. In a future where living in the Earth's surface has become undesirable. People are building colonies in Earth's orbit. If materials from Earth are used to build ...
I was reading this question and realized that I didn't actually know enough to give the answer that I wanted. Obviously in the near term, all our raw materials come from the Earth. The only oth...
Given a Medieval or Middle Ages level of technology - leather bellows, etc how close could craftsmen come to achieving a near total vacuum in an enclosed space. In context, I'm trying to create a ...
Think of HAL9000 playing a chess game with Frank Pool: Thank you for a very enjoyable game. Would that have been literally enjoyable? In a world where A.I. exists, as depicted in this kind o...
I realize that creating worlds with multiple moons and/or suns is risky, but I'm toying with an idea to see where it goes. So, a planet has 3 moons. One is large like ours, the second is about half...
Can large amount space debris be used to block sunlight from falling in a particular land area (about the size of Hawaiian islands)? If so, how much space debris will be required? What will be the ...
On Earth, photosynthetic organisms require additional nutrients to survive; in addition to "feeding" off of sunlight, plants respire and absorb water from the ground in order to grow. However, th...
On Earth, the planet itself is negatively charged and the clouds are positively charged, causing lightning to travel from the clouds to the surface. While there are significantly smaller wisps of l...
Suppose there's a planet that has similar characteristics of Earth and can provide life, suddenly shatters in many pieces and scattered over the system. A small but very dense object is attached in...
When designing a world it is convenient to decide how places will be named: Elements like the continents and the oceans. However, it is likely that the different cultures of the world will not ag...
I heard that some scientists placed chickens under 2.5g for 6 months, and they survived. A normal human would black out at 5g. A trained astronaut could take up to 8g before blacking out. 20g woul...
If a planet existed in an orbit where the asteroid belt is, would the orbits of all the planets be stable, and what would the climates be like on these planets? Assuming there could be a planet in...
A space colony that resembles the design of a Stanford torus generates artificial gravity by centripetal force. Discussions about benefits of such fake gravity can be easily found: no more constan...
I am currently designing a megastructure which is supposed to provide living- and workplaces for about 100.000 people. It is supposed to be designed in a way that it provides everything the inhabit...
In a future where all cars and public services are self-driving the way, I am assuming traffic congestion would be seriously limited, if not removed completely, because the road network would also ...
