So, on a previous question of mine, someone answered that it would be feasible to build a city on a waterborne floating island using a pumice layer below the ground. That got me thinking about the...
Ecologically, when you're within the latitudes of 23.5 degrees, you'd find yourself in rainforests rich in diversity but poor in nutrition. The forest floor is a barren mess simply because the can...
Cosmic rays are energetic particles coming from space that hit the Earth's atmosphere and produce a lot of secondary radiation (some of which we see in visible light as aurorae). Would it make sens...
Tech level - comparable to contemporary; no fossil fuels, all fuel has to be produced synthetically, as simplest to produce (and store!!!) was selected methanol. Theoretically quite good - superio...
A quote from Story of Your Life (the short novel that Arrival movie is based on) Colonel Weber frowned. "You seem to be implying that no alien could have learned human languages by monitoring o...
This question's main focus is the building aspect of the nanites. Rulez: No pseudo-science. No handwavium. The backstory is not (that) important. Lame puns ahead, proceed with caution. P...
Lets say there is one being (it can as intelligent as a dog or an average human). But lets also give it/him a bit more unorthodox situations. He/it doesn't need to sleep and eat. Nor also his cel...
What restrictions this planet must have to make it possible? Planet can have any size, be made of any material A human must be able to land in it and observe it, dust added to the planet from the...
Word on the street is that carbon nanotubes may be the future of construction. Apparently, a skeleton of this material would be stronger yet lighter than a skeleton of steel, which could mean exte...
Far into the future, humanity is largely split into 2 groups. The first group consists of space-dwelling humans, who live in enormous space stations equipped to sustain human life indefinitely, ...
Can you have separate countries in a post-Earth world where humans are colonizing space? I am not talking about physical territory per se, but rather the different identities between separate state...
There is a settlement moving along the terminator line on Mercury: I can build it within $\pm 2^{o}$ of the terminator, that is, in the daylight side or the night side. There are going to be lots o...
This is not a very hard-science-fiction tale, but more about human relations and adaptability, but I still want it to sound plausible. A space faring civilisation that descend from humans uses bio...
I want to create a modern population which is adapted to stress. Meaning people could take immense mental pressures without getting into mental disorders. I thought a way to do this would be to bri...
Year 2317 C.E. traffic report: heavy traffic expected along upper Curiosity sector H-311 going towards Juno boulevard, there is an accident at Exit C right lane, so vehicle leaving for Europa via t...
In the game "Stelaris" torpedoes and missiles are different categories of weapon. Presumably they wanted to include numerous kinds of weapons for the player to chose from. These weapons are all lau...
Without magic, is it possible for a plant to channel light (all colors) to/through its roots? What I'm thinking is having a giant cavern with a bunch of these plants above. The roots go down and ...
Imagine that you want to colonize Venus. But a day on Venus lasts 4 months, and that's terrible. The big brains at the Science Palace have decided to make Venus spin faster, so that the length of d...
Setting So for generations a ship has been traveling through space. After reaching their desired destination you are left with a group of people who have been used to their largest spaces being no...
I have read in a book review of "Fallen Angels" that a high-tech torture machine, which "administers drugs and medical attention while busy cracking teeth, flaying skin and breaking bones" and "ren...
It has become accepted knowledge that the planet Earth was birthed via a swirling cloud of dust and gravel clumping into larger and larger pieces of rock. It began 4.54 billion years ago, and 100 ...
Would it be possible for a civilization with absolutely minimal knowledge and use of electricity (Light-bulbs, basic electric motors, and archaic radios) to reach space? I was thinking that a soli...
In my world, an intelligent species has evolved to the point of space travelling. However, this species can eat only one single type of food (which is a product of another species on its planet). ...
So one theory of the universe is that eventually the universe will collapse, "The Big Crunch". And the cycle between Big Bang and Big Crunch has cycled previously and will cycle over and over agai...
If we had to keep a channel for lunar communication with modern technology such that it was always open regardless of earth-moon positioning, how would we do it?
