Assuming that there's not an issue with diseases spreading around, and that there's little to no issue with food allergies, what would the effects be of taking someone from a tropical climate to on...
Several science fiction books picture bigger Terran planets with higher gravity. I'm curious to know what would be the maximum gravity mammals similar to the one on earth could survive. Only bones ...
I have a colony of humans on Mars, living in enclosed cities to maintain breathable air. (If they need to leave, they suit up.) Assuming modern-day technology, how do I figure out how many people...
I am writing a book where organ printing has advanced such that humans can grow full hands, arms, legs, and every inside organ. This process is used to "make" soldiers in Earth's future because clo...
You gotta admit. That roguish guy you just met at space bar looks cooler with cig in his mouth. Not only he always shoots first, but also he manages to do so while puffing awesomely looking clouds ...
My people are traveling in a generation ship. For some reason they can't make the ship radiation-proof. Their solution: genetically modify their descendants to be radiation proof. How could one mod...
I am building a nocturnal humanoid race for my science-fantasy setting. They are slight, quick, sneaky and very good at being unobtrusive. They are pretty much the goblins of my setting; though not...
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...
A world I am working on has reached a sort of material production singularity. Recent innovations in space mining, artificial intelligence, teleportation, and 3D-printing have allowed for devices k...
Yes, I know that this is quite a BORING question (get it ;) ), but I really DIG this kinda stuff (no really). If you have watch an action children's show or a cartoon of some kind, we have all see...
Scenario: The Moon disappears slowly -- within 3 days. It is a result of natural causes and we don't have any control over this disaster. What will be the Major Effects On Earth and life on Earth?
We are in a future where genetics has advanced to a point where arbitrary modifications can be done to living beings. Now a geneticist wants to make a flying human. That is, he wants to modify a hu...
Okay, so my character is relatively short (5'6 feet). Her bones are hollow,but similiar to a birds-very dense to make up for strength. Her wingspan is 16 feet. I want her to stay as humanoid as pos...
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 ...
Though the job of breastfeeding is typically known to the women, there are documented cases of men producing breast milk. However, these reports are few and far between, which means that while men...
So, to make it normal for a human to have tetrachromacy, having four color receptors, would make our night vision nonexistent. In an answer in the question linked above, someone brought up the tap...
Current technological level. (in the setting there is an awful tech stagnation, so waiting for better DNA engineering technology is considered as waste of time) Possibility to use all contemporary ...
These people inhabit an underwater city. In the city there are pools that connect the dry habitat with the outside ocean, this of course mean that the habitat is unpressurized and therefore the in...
I'm working on a deconstruction of a high fantasy setting. The plot starts with a female protagonist being forcibly summoned into said setting with few to none of her memories. The world is popul...
Mars has a couple of problems with regards to colonization such as lack of atmosphere, lack of magnetosphere, weak sunlight, and a few others. Of concern in this question is how to shield human col...
If the North and South Poles' ice melted instantly, what would be the effect on humans and other animals? Would the sea creatures thrive? Would a lot of land get covered by water?
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...
Some of you have commented here: "How Do I Supplement Oxygen Intake?." I mentioned confidentiality, but that is no longer going to be a concern. We just want to do this right. The original concept...
Series Premise Made Short: For reasons that I'm not allowed to describe here (confidentiality), Earth's deciduous and tropical plant life largely dies off. A hardy and oxygen-hungry microbe infests...
WARNING THE FOLLOWING CONTAIN SPOILERS! I watched the first season of The 3% and I am wondering about the wisdom in the strategy adopted by this world. Spoilers Specifically, if the 3% ( "smar...
Suppose in the future (about 3-4 decades in the future), we start preferring smaller people as mates. The average size of a human would go down, maybe as far as or further than average heights from...
I was wondering on others people's ideas on how to take a Space Age civilization and send it back to the stone or bronze age. My own idea was that war and disease broke out, crippling the nation as...
No matter which mammal you are talking about, be it a rodent or a bat or a cat or an elephant or a whale, all have the same lung size--7% of the entire body volume. In this alternate scenario, the...
A person is born with no senses, so he can't hear, speak or sense. The only way in which the world can communicate with him is through brain signalling. So they can send different signals to his b...
The energy source both in terms of fuel and electricity on my ship is nuclear fusion. Very precise nuclear fusion: there is no helium fusion until there is absolutely 100% helium in the main fusion...
Would it be at all viable for a person to have certain plant characteristics such as: Chloroplasts in their hair and skin, with the skin maybe lookmuch darker because of extra light absorbance (m...
On the generation ship in one of my stories and possibly more, there exists a positive relationship between the egg laying humanoid aliens who have an egg pouch on their chest and the humans they a...
I'm developing a world in the near future where a start-up company develops an artificial womb. Now well-off people could grow their children from their eggs & sperm. My story is about couples ...
Let's say my eyes were ripped out in some horrible accident, and were replaced with cameras. Over the years, the cameras get better and better... 4k... 8k... 16k... etc. Is there a limit to how hig...
Follow up to this question. Is it possible to translate the inputs from the optical nerve to something readable by a computer?
Humans as Ambush Predators Homo sapiens and many of our ancestors practiced a form of hunting known as persistence hunting where we just walk after an animal till it keels over dead from exhaustio...
Lore: "Not much is known about the past of Unus Solum. What is known is scattered and fractured. Unus Solum was a planet that was subject to colonization efforts. The Ark ships that came were pre...
I was wondering, how would a civilization of humans who can see only in grayscale live their life? There is none of them that can see color. Everyone sees every thing in gray. Yet, color actually d...
Evolution is a great system for incremental refinements, but it's not very good at drastic changes, and can leave behind a lot of inconvenient vestigial elements. It's also rubbish at dealing with ...
It's 100 years in the future, and we've decided to end all war and crime. How do we plan to accomplish this? Through rigorous study of personality theory and human interaction, we've identified 5...
Here I will talk about the digestive system of my Kepler Bb humanoids. Mouth The teeth are much stronger than bone(Strong enough that they can eat bones no problem). Other than that and all time ...
This is assuming that the direction of the gravitational gradient remains the same ("down") - it's just the magnitude that's varying. I don't need an accurate figure, just a ballpark one, which is...
I'm looking for the perfect kind of apocalypse that not only can kill great parts of the people on Earth leaving the survivors spread in little primitive groups across the world ,but can also avoi...
Basically I want to create a world in which some of the humans have developed a higher body temperature in order to survive cold, harsh climates, such as the poles or even tall mountains. The reaso...
The concept of "age" on Earth is based on the number of revolutions the planet has completed since one's birth. In a setting where interstellar colonies exists, of even in a setting where multiple ...
It is well known that in respiration, we produce carbon dioxide, while plants, via photosynthesis, absorb CO2. My question is, if 50% of all people die today, will the total amount of CO2 decrease ...
Note: This question assumes an earth-like biology. Could a microbe (probably virus) be created that transformed humans into plants? What I mean by this is that the microbe would take human cells, ...
In my fantasy setting, dreams are located in what could be called a parallel dimension - commonly known as "The Void". Some people are able to develop powers related to the Void through long traini...
