I'm spitballing a story where the main character goes through a monstrous transformation. Part of the conceit / my enjoyment is that she's an oncology researcher and will be tracking the transform...
Could nuclear energy be a basis for energy storage with foreseeable technology? One approach would be to use excited nuclear states, but I suspect they would be too unstable to ever be useful. Al...
Do {any, some, all} {unicellular, multicellular} plants require free oxygen? For example, would a cabbage asphyxiate over night, or even in daylight, in an oxygen-free atmosphere?
When water is electrolysed with graphite electrodes some of the oxygen reacts immediately with the anode to produce carbon dioxide. Does a similar reaction ever occur at the cathode, producing meth...
Can electricity be generated directly from nuclear decay? It occurred to me that in alpha decay two protons fly off rapidly, leaving their associated electrons behind. If the alpha particle was ca...
This is a multi-species animal army with predators of all shapes and sixes, foxes, lions, bears, tigers, leopards, wolves, lynx, eagles, falcons and so on. The herbivores have been excluded from t...
I have seen a variety of outer space megastructures across sci-fi and the minds of most astrologists, such as Bishop Rings, O'Neill Cylinders, Bernal Spheres, and much more. What most of these inte...
Right now I'm currently trying to calculate the average surface pressure at sea level of an atmosphere, but I'm having a struggle finding the relevant formulae with which to determine this number. ...
Inspired by many questions that make use of utility fog. Utility fogs are not, as the name might suggest, fogs, but rather lattice solids. Cells of the foam are pollen-like micrometer-scale mach...
Most animals that glide are rather light and small. Flying squirrels, Colugos, and sugar gliders all weigh but a few ounces. The largest gliding predators are snakes of the Chrysopelea genus. Agai...
My question is: what needs to be changed in the body of my genetically modified people so that they can safely drink toxic water ( most often industrial wastewater is contaminated with industrial w...
Contrary to popular belief serpentine dragons are not in fact magical or related to the European wyvern but instead are descended from the Chrysopelea. some common characteristics of serpentine dra...
Humans are not the fastest mammals on the planet, but for very long distances (more than 40 kilometers) we can overtake any species living on land. Except some dogs. The best runners on ultra-long...
My question: What is it that needs to be improved or added to the human body so that it can withstand critically (fatally) low and high (if, my genetically modified person is underwater or a very d...
Sort of two questions here, but very related. One about whether a mammal-like animal could evolve to have a chitinous endoskeleton, I guess. Then a question of whether, if they grow horns, that ske...
In my story, I have a small extended family of 30 to 40 individuals ranging in age from 0 to 50 who are on the run from Chinese and Japanese forces in 1400AD. No place in Asia is safe for them. By...
Short question: which hormones should high contagious fungi spores produce to make their human host spread the joy and infection (by hugging and kisses) on early stages of infection, and become p...
I'm thinking about designing an alien race. The race is carbon-based and evolved on a world with an average surface temperature between 40 and 60 degrees Celsius. Now, on Earth, almost all lifeform...
The response time of the human visual channel in a relatively quiet state is approximately 40 milliseconds, which provides a" frame rate " of 25 frames per second. At the same time, it is not just ...
For complicated reasons our hero's blimp in the Venus atmosphere at an altitude of 50 km gets a tear in it and sunlight floods inside (there is no gondola, the blimp is a semi-ellipsoid of breathab...
What needs to be changed in the structure of the human stomach so that a person is almost completely immune to poisons and toxins ( especially interesting regarding the poison of puffer fish, Gray ...
In many fantasy worlds, giants are as intelligent as human beings and others races that they either avoid stepping on or step on regularly. However, due to the square cube law, giants have a limit...
NOTE: If there is anything about this question that needs clarification or editing, please don't hesitate to let me know in the comments. Get ready, because you're in for quite a ride. I have t...
So, one of my D&D characters has a cut/relief-carved quartz crystal amulet (medallion shaped) that's both an arcane focus (crystal) and a holy symbol (amulet), and I thought it would be a good ...
I have posted a similar question where I asked how can two realities mix into one reality in which I received many helpful comments. I realise I should've expanded on the details I posted, so I wil...
This is my first world and I want to build in a way that is physically possible (if this is possible, otherwise make the necessary changes) for my civilization (which is mostly fleshed out) but I d...
Respirocytes are an artificial analogue of red blood cells. Tiny sapphire capsules that can absorb oxygen in the lungs and release it in the capillaries. From the capillaries to the lungs, they, in...
In my scifi setting small utility robot swarms are used for many purposes. I'm currently trying to estimate how much energy such a swarm would need to operate. Since biology, robotics and nanotechn...
Assuming all the primary hurdles in building a space elevator are overcome, would it be structurally feasible to attach intermediate stops along the length of the tether (between the planet and GSO...
I want to launch the heaviest booster + spaceship possible in about 1.5 of earths gravity, using the technology we currently have. To make things easier, imagine there was the same atmosphere as on...
Quantum Computers are considered a more powerful type of computer than so called 'classical' computers. While a typical classical computer could be considered as a black box that can solve Polynomi...
I am wanting to make a 3 world lagrange system around a Sol analog star that includes 1 gas giant and 2 terrestrial worlds with large moons. I want the terrestrial worlds to have a similar gravity ...
Let's say Santa got himself a new toy: a present delivery cannon. With this new cannon, he wants to deliver presents to children by shooting their presents from the cannon into their chimneys. Let'...
In FTL-free universes, interstellar travel is often done by vessels capable of continuous acceleration (the drives themselves are often magitech), which can use the effects of relativistic time dil...
I've had a number of interesting conversations with people about how the cosmic microwave background (CMB) will evolve in the future. The CMB is the sea of photons left over from the epoch of recom...
In my story, a ship is built in orbit around Earth, designed for a 20-person scientific expedition to a planet 11.4 ly away. It will accelerate at 1g for half the distance, then flip around and acc...
Prosimians on average are not as intelligent as their simian counter parts with the notable exception being lemurs which live in semi large groups. what I want to know is could a group of prosimian...
My planet is tidally locked, airless, and has no magnetosphere. It's located close to a flare star (5% solar mass, 11 Gyr old), and is in it's habitable zone. The strongest flare ever detected on E...
I am trying to understand if it would be possible for organisms to evolve by different means other than random mutations and natural selection. Eukaryotes were predicted to be formed by fusion with...
A thought occurred to me, and I wondered if it could be made practical... This video talks about the possibility of electrical battery powered planes, and in short, while it may be practical to bu...
We have at most 100 years to abandon earth. The 10-km asteroid which killed the dinosaurs has hit the moon head-on instead. As a result, the moon has slowed down and it's orbit will decay by 400,00...
Effectively what the title says; What would different observers experience while travelling through / seeing one travel through the tube, and how could they be used to cut travel times? (Just answe...
I am currently brainstorming a hard (like the hardest possible; everything that occurs in the story must at least be theoretically possible) sci-fi story which will take place far in the future. I ...
What is required for advanced lungs to filter dangerous chemicals (so to speak, to carry out the detoxification process) and then use oxygen? (It is advisable to take into account the above record,...
Stun-wizards specialize in blinding and deafening opponents at a distance. To do so, they can exert their magical power to manifest a spherical region of vacuum by essentially "telekinetically" pus...
