Whilst not strictly relevant to this question, the questions and answers may interest the curious: this is the 4th in a series of question here - 1, 2, 3. My population (in excess of 500,000) und...
In the movie Kingsmen, there is a poison which behaves differently from most other poisons. It has to be ingested in order to kill, but that is not enough. It is harmless until a radio signal is b...
I was inspired by Dead Space which had cloned organ banks for transplants due to mining accidents. I honestly found this idea intriguing so what I'm wondering would it be practical or do better alt...
How fast can nanites work Tangential to the above question. This is for a novel about a somewhat near future. The conceit is that very advanced nanites, plus computers that are able to read our mi...
For visual reference: Apes are visual species who rely more on their eyesight than any of the other senses. As a result, they see the world in three shades of color, whereas other mammals see i...
For a space-based story I am writing, I was hypothesising about how to have organisms that can thrive the vacuum of space. Ignoring plausibility of such a creature evolving, I realised a few probl...
What I'm using your information for: My planet is small, has a thicker atmosphere than earth and it's orbiting a white dwarf. The main reason I chose it to be a white dwarf is that I read somewher...
Rats are commonly associated with illness and disease due to the role they played in The Black Death. However, some works of fiction portray rats as carnivorous swarms, devouring people indiscrimin...
I was thinking of a life form with a similar surface temperature to Earth, as well as a similar temperature variation to that of Earth. Could such a life form evolve an organ for generating temper...
If you have miles of steel pipes 10m thick, could you pump water from the sea to the centre of Antarctica, then pump it into the air like a geyser so that it falls around the pipe. As the fallen se...
After several centuries in exodus, humanity returns to earth to recolonize the planet. Naturally, their first question is the same as mine: Where are the best place(s) on earth to settle? Paramet...
During an ice age, would it be possible for a great lake to be frozen while a relatively nearby river was still running? To help illustrate my point: Would it be possible for Lake Michigan (or par...
Dragons are awesome, but they're still vulnerable thanks to their low-numbers and a certain type of people... So, to prevent those from killing even a single dragon I came up with the wedding ring...
Planetary conditions: ~0.5x Earth gravity (guess: 0.9x Earth density, 0.777x Earth radius, so about 0.42 Earth masses... but that's probably not important). Atmosphere broadly similar to Earth but ...
I assume a planet like earth. Obviously the Amazon river is fed into the Andes mountains as well as other rivers that give water to the system. Could the same amount of water come from a specific c...
I'm currently bouncing around ideas for a sci-fi / cyberpunk world and one of the major technologies in this universe is the manufacture and usage of metallic glass. I don't want to handwave too ...
I'm writing a soft scifi novel that has its fair share "fi" but every now and then I feel it important to acknowledge some "sci." In this scenario, a spaceship is in orbit and about to land on E...
I'm creating humanoid specie with two subspecies Hairy races - roughly based on humans, chiss, mirialans, with standard males & females sexes Tentacle races- roughly based on asari, twilek, t...
I'm creating a near future world where one faction is using high energy density batteries that enable their vehicles to outperform gasoline based technology. Like cold and silent aircraft and helic...
What would the consequences be of a high number of solar systems being within close proximity to one another? I'm mainly interested in the consequences for life on multiple planets. When I say 'clo...
My character has a prosthetic, or technically you could say a bionic or cybernetic, left eye. For one reason or another, the replacement eye couldn't be connected directly to the optic nerve. Inste...
I've created a fairly fleshed out, detailed FTL concept. Basically, you have a circular starship, with a ring of tungsten encircling that, held in place by an antigravity ring beneath it. The rim o...
Flame lickers work by sucking hot air into a cylinder and then relying on the cooling of the air by the cylinder wall to create a partial vacuum to pull the piston back. see video In an alternat...
This is Yeola~Camay. A double planet orbiting Sharro, an ordinaryish star somewhere in the universe of Far Far Away. As you can plainly see, Yeola is the planet on the left & Camay is the p...
Is there any reason an elevator, moving from the central hub to the outer ring, would not function on a rotating wheel space station with artificial gravity? Any parameter of the radius or rotatio...
