I'm trying to speculate on manipulating things on the level of quarks for a story. What could I do with that type of technology?
This is the world's tallest tree--the coast redwood. It can grow as high up as 115.5 meters. Any taller, and the transportation of water in its vascular tissues would not climb all the way. Bu...
There are several questions related to effects of different gravity levels on the human body, but none adequately answer a fundamental question: What is the maximum and minimum gravity that nearly ...
Would it be feasible to have an interstellar vessel be constructed in flight after smaller sections are boosted up to speed? The idea here is about using laser sails which would be easier to use wi...
In Star Trek, going faster then light will take you back in time (Possibly in real life too!). But I've noticed one inconsistency. Ships, even when going faster then light, have a finite speed. By ...
I have a species of megafaunal carnivore that are extremely mobile with territories spanning hundreds of square miles and lifespans of 120-150 years. They lay clutches of 2-3 eggs every 20-30 years...
I was thinking of a story with a Werewolf as a detective, using mostly conversational skills and his sense of smell to solve crimes similar to many of the UK types of detective stories (Morse, Lewi...
My advanced human civilisation often has high-acceleration ships travelling at near lightspeed. I know that time dilation would have a significant effect on the time experienced by the crews, but I...
The universe as we know it has ended. The concept of "natural" illumination ended when the last red dwarves and quasars died out. Now, only brown dwarves and blackholes dot the empty void that was ...
In an Earth-like planet filled with humanoid creatures (upright, two legs, two arms, head, etc.) the inhabitants have evolved to grow bowlegs. The question is why? What advantage would it bring...
What would be the economic trade offs of building fusion powered rockets vs building laser relays across the solar system? What assumptions would you need for each one of these to be the superior o...
For my middle-grade science-fiction novel, I need to come up with an invention or chemical that could rapidly create icebergs to refreeze the Arctic and slow climate change. Kurt Vonnegut's Ice-9 i...
Genetic chimerism is a condition in which a single organism is composed of cells with more than one distinct genotype. Elves inhabit this world, but do not possess magic in this reality. Instead, t...
It's something that's been used several times as a plot device on Star Trek, notably in the TOS episode "The Tholian Web", and the TNG episodes "The Next Phase" and "The Pegasus". I'm certain it's ...
First question on stack exchange I've been lurking and learning for years and finally decided to pose a question for a novel I'm working on. Given the appropriate advances in material sciences an...
In some birds especially owls, we can observe a structure called facial disk, which is mainly composed of feathers and helps to direct sound to their ears. While being more common in owls, adding u...
I was wondering what the best ways for turning minerals mined in the asteroid belt into useable materials would be, so far I came up with three methods, utilizing nuclear, electromagnets, and final...
Most of the humans on my alternate universe's Earth have gone extinct due to a global war, leaving a handful of survivors and the buildings to serve as a reminder of how great they once were. This ...
We may all have some familiarity with winged skulls - from Avenged Sevenfold's album covers to bikie shirts. However, for my science-fiction/horror story, I am curious about how these creatures wou...
Earth sized planet in the goldilocks zone. Similar mineral composition and surface water. Photosynthetic life evolves and thrives on land and sea. Atmosphere and climate comparable to the beginnin...
My temple was built near a kaolin surface mine, which is itself topping an old deep mine (where they used to mine radioactive metals, rare earths and possibly other miscellaneous, if need be). This...
In the large pillar forests of planet x, a group of vertebrates, in order to hunt down the fast climbing creatures that inhabit their habitat, rather than developing speed as well, went on another ...
In a setting where an empire establishes an island colony far to the north, what is the coldest climate such a colony could sustainably survive were that empire to collapse and stop sending supply ...
On plain Pilar forest biome of planet X, you have mostly 3 types of vertebrates: those who burrow under the ground those who run through the widely separated trees those who live above ground le...
I got an interesting answer to one of my questions and I would like to know some additional info. A myoneme (or spasmoneme) is a contractile structure found in some eukaryotic single-celled o...
