If an extraterrestrial race were to send a signal to earth containing a virus (technological or psychological), how could that signal then infect our technology and then be received by humans?
so in my world the rivers and lakes (not sure about the sea yet) are made of blood that'll never dry up. The blood maybe fresh or not (I still haven't decided yet,probably both anyway) i also haven...
I want to design a realistic interstellar spaceship that uses centrifugal force for only the crew quarters. But while looking up for designs I found the most common ones are the torus or ring desig...
I've been thinking of having an underwater structure in a world with ice, but I would think water from currents would melt the ice. Would there be any way to keep it frozen and have an underwater ...
This came out of a discussion of an all female colony world, but I'm interested in the more general version of this question. Is there any function in society that requires male levels of strength ...
I'm creating a fictional world which includes tree dwelling octopuses that thrives in swamps and tropical rainforests. I'm wondering what evolutionary pressures could lead to the rise of such crea...
We have, perhaps, all experienced those 'heat' packs wherein a local disturbance causes a crystal structure to rapidly dissipate through the medium, releasing heat in the process. Nothing really 'm...
The muroids are a superfamily of rodents consisting today of mice, rats, voles, hamsters, lemmings and gerbils. There are at least 1750 different species of them, proof apparent of their environme...
The story takes place in Alpha Centauri, with this binary orbiting just over 1 AU from Rigil Kentaurus. The star system will tightly packed, but following the 10 Mutual Hill Radii separation setup....
This question on space stack begins to tackle how a bird could fly inside an O'Neill cylinder, https://space.stackexchange.com/questions/27665/can-birds-fly-inside-an-oneill-cylinder. Here is the ...
So for this question there's a Mad Scientist/Dark Lord that wants to engineer a race that can out breed mankind and carry him to victory. He has access to sufficiently advanced genetic engineering...
We are in a far future setting where humans (or transhumans I should say) achieved two things: be able to modify themselves genetically to the point where they can have completely different organ...
I'm thinking to build an island by pouring lava into the ocean, with the advanced technology, around 40 years later, by making a special pipe connected to the ground (maybe near volcano/es) since t...
Bronze is an alloy of copper and tin, and copper is a significantly more abundant metal in the Earth's Crust, at about 70 PPM compared to tin at 2 PPM. Because tin was the limiting factor in bro...
After centuries of careful search and travel, some intrepid extraterrestrial explorers have finally found another inhabited world! Elated with their discovery and exhausted after their long journey...
Previously, I asked about the plausibility of a sulphuric acid dragon. As it turns out, the answer was right on Wikipedia, namely a. thiooxidans and the snottie Snottites are highly acidic biof...
Imagine a huge salt flat like Bonneville or Salar de Uyuni. Due to other logistical concerns, commerce between the economic powers on either side of the flat is forced travel across it. This has re...
Okay, so I want you to think of someone similar to Clayface here, only he's not limited to just clay. What I got for him so far is that he was once an ordinary man until a cluster of specifically...
I will be making several posts on this community regarding questions which involve the design specifications of an alternate human species I designed. Because I'm not a biologist, and I have no ide...
This is a submission for the Anatomically Correct Series Residing in South Africa, the Grootslang is a creature of African folklore being depicted commonly as: Being 37 to 40 ft long having a co...
So, mechanical computers are a thing, as are pneumatic and hydraulic actuators. Combining those ideas, it's not that hard to design simple purely-pneumatic/hydraulic robots--provide them with a so...
Leaving aside the matter of how well would humans fare on the surface of Mercury (we only have to factor in the weight of their life support: air, water, food and spacesuits), and assuming material...
In the "Legend" trilogy and its sequel "Rebel", author Marie Lu envisioned a far future where Antarctica is a superpower decades after the United States splintered into two separate countries. The ...
It's the future. The setting is about as "hard-ish sci-fi" as it is possible to be, with the one big exception of a viable FTL engine. Humans have began spreading out into the galaxy, colonising n...
The year is 2100. While climate change has wrought serious damage to the biosphere, humanity has at last managed to become carbon neutral, and has even developed technology that can be used to redu...
