Related to my other question. What would be best conditions for a natural super colony of pearl oysters and the best conditions for them to produce pearls naturally. Shallow or deep waters? Slow...
I want this world to have two things, typically on the complete opposite end of geological timescales: Land fauna is incredibly "Young" - Pretty much nothing larger than a "large" insect (Some li...
First, specifying format in this question I will be giving temperature ranges that sometimes appear backwards. This is because I am listing average temperature ranges from southern to northern lat...
Let's assume the planet has only one half the mass of the moon and is covered by shallow ocean. To eliminate water pressure at extreme depths, assume the ocean is also quite shallow, with a maximum...
Enter the [Insert cool and awesome Latin name here] - this species is 3 times the size of a lobster from front to tail, and a powerful hunter. Operating in swarms, they are my worlds equivalent of ...
In an alternate timeline, Ceasar lives, forges an alliance by marriage with Egypt and dominates the entire Mediterranean. He then performs a raft of economic and political reforms that basically sk...
BACKGROUND I'd like my earth-like world to have a naturally formed narrow strip of land that bridges a major sea. Now, before anyone rushes off to comment about island chains and land bridges, I'l...
I've been trying to figure out a model (or find a relevant paper) for calculating the approximate day/night and periapsis/apoapsis temperature variation for an earth-like planet that has a high ecc...
Scenario: Say we have a massive release of greenhouse gases into Earth's atmosphere, however much for the ocean around Antarctica to get just warm enough for hurricanes to form during the summer (2...
I am writing a fiction set in the 'dark ages', a pre-industrial, pre-gunpowder world. On Earth that would be no later than 800 AD, but this doesn't have to match Earth. There is no magic, and I won...
In a fictional setting, an Earth-like planet is orbiting another, Jupiter-like planet. For explanation see my previous question Which astronomical or cosmological event would explain periodical lo...
For my future world, I've decided that coastal cities need fresh water and there isn't enough of it to go around. I don't know how jellyfish work. Is it feasible or completely impossible for sci...
/Edit : so, I would like to create character which is supposed to have some metal grafted under his skin, but by under his skin I mean straight under, like a second layer. This is supposed to be li...
What would be a situation in modern times where normal, healthy people would want to get infected by a non-curable, but non-lethal, virus? A virus that would have pretty nasty symptoms. There...
Scenario The straits of Gibraltar never quite opened and the entire Mediterranean basin is dry land apart from a few large salt water lakes at the lowest points ~5% by area. The Europe "“ Africa la...
My world - basically Earth all along, unless told otherwise - is populated by humans and few fantasy-based "races" (actually, species - any interbreed offspring, if possible, is infertile): elves, ...
The Scenario: A technologically advanced mother culture wants to manage mass outbreaks of virulent disease in its technologically regressed colonies, who are inclined to resist most of what the mot...
So I have a brain parasite that needs to enter the skull of a host organism (in this case humans) with the least amount of effort, but is too large to enter through the circulatory system and must ...
Background story: In near future (max 10 years from now) mega-rich person suffers yet unknown disease. He obviously employs every doctor possible and spends loads from his fortune on researching, w...
In a SciFi world I'm building with other people, we'd like to create a planet with an infection outbreak going on. There are wildlings. They are pretty primitive, have stone tools and wood houses. ...
In Plague-inc the most typical strategy is trying to infect everyone, while staying hidden by not harming infected people (when a virus, bacteria, fungus is found, people start working on the cure)...
I have been working on the idea of a mammal following an evolutionary path similar to whales, which started as semiaquatic before becoming fully dependent of its underwater enviroment. So how could...
Let's suppose Paleozoic marine creatures (Trilobites, early fish, and many else) has appeared in oceans of 2017. What kind of advantages and disadvantages will they have when they compete with mode...
Has a loose base in this earlier question of mine, although today we will be working with modern (roughly) tech levels and bacteria. It was pointed out in the accepted answer that bacteria might be...
An illness has been slowly spreading throughout the inhabitants of my agrarian society, decimating villages. The first sign of infection is the excessive production of slimy yellow saliva, and sinc...
Is it possible that there might be a virus (of the giant, ancient, frozen-in-glaciers type) that is, for lack of a better explanation, double-layered? As in the first layer affects the host and the...
I'm interested in developing a world that has somewhat extreme seasonal changes (hot, but liveable summers and cold, but livable winter) with a very cold non-habitable polar regions. Would axial ti...
I created a world a few month ago for a role play game, Ryuutama. The game system is higly based on season and weather, but I'm not good in time gestion as GM. I so decided that regions will have t...
The Black Death, which claimed an estimated 75-100 million lives, was one of the most devastating events that is still well known today. What conditions would allow the plague to spread and kill ...
I have an idea for a short SF story, where an alien race infects a tiny village with a virus, which eventually spreads to entire Earth. And I need to know what minimum time is required to infect th...
Ignorance is curable, living is forever. Robert A. Heinlein1 Cutting to the hard data: Due to some or another reason2 the genetic information stored inside cells (aka DNA) of my Immortals d...
A common trope in zombie mediums in to base the virus off of rabies. While this choice does have some obvious reasoning to it, it has been long over done. Relatively recently, The Last of Us came o...
Would it be possible that other planets, or even other random celestial bodies, contain different types of pathogens? According to Wikipedia, the known types of pathogens are: virus, bacterium, pri...
I am trying to create a planet for a fantasy role-playing game where the equator is an impassible region of ice. Ideally, I want to find a science-based solution to this and not have to resort to ...
Part 1 On Earth, we have seasons due to our planet's tilt. In my last question, I proposed an alternative world where the seasons were instead caused by an eccentric orbit. Now I'm going for somet...
A Milankovitch cycle is defined in Universe Today as a cyclical movement related to the Earth's orbit around the Sun. There are three elements to a Milankovitch cycle that affects the amount ...
The orcs in my world are humans who have been infected by two different diseases: An airborne mutagen that permanently denatures their myostatin receptors, which prevents their muscles from being...
I am aware of the square-cube law, so what conditions do I need for this to work ? The tortoise will be a similar size to the isle of Wight and will walk around in shallow areas in the ocean. What ...
My Kepler Bb world has in total 8 seasons. 4 of those are transition phases. Their year begins on the first day of spring and their months with 9 day weeks are 65 days long. But that is just in Kep...
I did some quick research on DNA and I know it can be damaged by different sorts of mutagens. I also know that this kind of damage can lead to cancer. Though I'm not entirely sure of where exactly ...
I won't claim to be a biologist, but I'm fairly certain that it's really hard for disease to survive in space because most bacteria and viruses need a host in order to survive for long periods of t...
If there existed a planet that was made completely of liquid water, no solid matter at all, what would the core of such a planet be like? Let's assume that this planet has conditions similar to ear...
By using antibiotics too frequently, some argue, we're setting the world up for a pandemic that we cannot treat. Every time an antibiotic substance is used, the bacteria that survive reproduce. Ev...
So I'm thinking about an underwater civilization and everything related to it, and I got to thinking about how they would communicate over extremely long distance. I knew that underwater species l...
If there's a habitable planet that orbits two suns like the above orbital route, what would possibly occur on that planet? Would it have two yearly seasonal cycle (compare to earth)? Would it be...
In the future, AI systems sanitize humans as they walk through doorways. Home surfaces self-sanitize. Food is mostly 3D printed from cleaned particles, including Vitamin K and possibly some probiot...
Would it be possible for a virus to extend the average human life-span (but only by about 50-70 years max) if the infected people kept it controlled enough where it wouldn't (alternatively) kill th...
Had a random thought. I was wondering if a uranium deposits underwater could result in radiotrophic plants or bacteria to sustain an ecosystem. One issue with this, is radiation has very short att...
What are the effects of introducing 2600 sharks of the primitive Edestus Gigantus specie* in modern waters in different places on earth? Will they survive, how ? for how long? can they destroy the...
