Suppose humans have developed the technology to travel between star systems. This might be some science-fiction method like warp drive, jump drive, peanut butter drive, hyperspace drive or whatever...
500,000 people have been kidnapped from all over the world by aliens. The aliens want to see if humans have empathy, and they can't understand our languages, as we speak they hear just random nois...
So, I'd love to have werewolves in the world I'm building, but as it's a sci-fi setting I don't really want them to be magical. I can stomach some pseudoscience, but I want the process to be as rea...
Let's say humans moved to Mars and have lived there for millions of years. Mars is of now uninhabitable, though in this case some terraforming has happened. The poles have been nuked to release gre...
Many fictional characters,specially in the anime art have shoulders bigger than any other upper body muscle. Normally the obliques,chest and latissimus dorsi are the biggest muscles in the upper bo...
I remember playing this game back in 2010-2011, and In minecraft if you found a waterfall you could actually swim it up vertically, it was difficult but possible. Does this apply to real life to...
Usually when a population overgrows it expands in search of new land and if the fields are virgin and empty they become farmland and cities, but if the fields are already occupied and the resources...
I'm writing about a setting where building technology is quite advanced, but elevators have not yet been invented, so the limiting factor on height is ergonomic. What would be the maximum practica...
Very narrow question: assuming an immortality treatment keeping people at a biological age of a fit 30's, free of infections and cancers & ruling out death by aging, how long would people live ...
So some magical human-like creatures called Altum come from another continent (in my book) to this human populated continent (both are about the size of Europe). They want to help humans become a b...
In micro-gravity and zero G, people's muscles deteriorate. If you sent a set of already very physically fit soldiers to train/live on a high gravity planet, would they perform better than other sol...
This question is similar to "How would the human eye need to change in order to see in low light without any changes to physical appearance?", including the apsect of change to the human eye, only ...
In my world, 3-inch humans live on an Earth-like planet. My question, provided by a comment on a previous question, is: What would an anatomically correct 3-inch human look like? How strong would ...
In my world, which has an Earth-like gravity and environment, an adult, fit humanoid male is 3 inches tall. When I do a simple ratio calculation, I come up with him weighing 7.9 pounds. Basically, ...
Please note that I have had some incredibly helpful and useful suggestions here that I have decided to make some major revisions as a result. I will reduce the overall atmospheric pressure and part...
A small minority (on the order of one in one million to one in ten million or so) of men and women in this world tend to suddenly manifest their supernatural heritage/psychic abilities/superpowers ...
This is question is related to the medieval world from my earlier question in which several types of intelligent hominids evolved in isolation, until they were rediscovered, conquered, and bred int...
Well, today I have a fairly simple question. Is it possible for a human to have some sort of birth defect, mutation, disease or something that causes the human body to be unable to produce body hea...
Let's say that in a different timeline, humans evolved to eat insects. How would that change the world today Note: Suppose that this didn't have any mass changes on our anatomy and that our species...
It's common in sci-fi for large medieval-esque populations of humans living in the ruins of a former technologically advanced civilisation. My story is one of these, with a large population of huma...
Gender roles have been historically assigned at birth. As soon as parents establish the sex of their children, they are molded into certain social categories. But what if humans didn't display sexu...
For example, a street this wide to have enough blood run down the length shown in this photo? Assume that the blood isn't going down storm-drains for whatever reason and assume the stretch of road ...
Say we are able to mass produce clones for our clone army and give them memories. Then we decide to give them the same template/personality/identity/etc. What psychological effects would this have...
Exactly what the title says : Could mass human cloning be feasible? I have a two criteria : Clones must come out as adult Cloning process must take a maximum of 3 months Optional : Clones must...
Suppose an evil genius (in 2015) wants to kill as much of humanity as possible. But he's on a budget; despite his years of stealing priceless historical artifacts, and despite having been selected ...
Okay so I just got off an episode of Gotham where this electrician villain dude uses shock therapy to reprogram people to do his bidding. Then I remembered that the brain operates on a sort ...
I had the idea for a group of advanced humans using technology to rework their bodies so that they lay eggs instead of giving birth to live young, just like a platypus (possibly to survive in an al...
Just for curiosity, I am a diabetic and I was wondering if humans would suffer from the same ilness if they were on other planets? Does the climate on other planets help the immune system? Will the...
I'd like my world to have humanoid protagonists, while still reinforcing that they are ultimately not human, but have simply evolved in a similar way due to convergent evolution. To provide a const...
As requested by JBH, I edited this question to fit the Anatomically Correct Series. The classic zombie is no mystery to anyone: undead, eats people and multiplies by biting humans. Could they ever...
Say there's a torture technique that hangs people by metal chains (gruesome, I know; stay with me) and the room slowly heats at a steady rate. (Like boiling a frog in an increasingly hot pot of wat...
Assuming there were no extinction level threats to the dinosaurs, and they never fully died off (and survived the following ice ages), how would this affect the evolution and technology use of huma...
The world I'm building relies on the fact that the whole population is sterile, and all babies are conceived in vitro. They do not have bellybuttons anymore but they still have genitals, and do not...
Where am I? It is so dark around here... Hopefully I have a torch. It looks like I am in a very long corridor. Time passes What? No this couldn't be! I walked straight in front of me d...
As we see today the interconnection between the brain and computing is becoming thinner day by day, we could imagine a future that where we could install additional artificial neurons. In a world ...
Somewhat similar questions have been posed before, but what I'm really interested in is what selection pressures would be necessary to produce a subspecies of giant humans, about three meters in he...
I'm designing a mission to a planet orbiting 61 Virginis (27.9 ly distant), and want to stay within physics that we're aware of (e.g. no warp drive). I've asked questions here and here, and the an...
The origin of Superman is fairly well known. A baby is sent to a planet and gains super powers from being in the environment (technically the sun, but I believe you catch the gist). I'd like to mak...
My question has to do with living inside a spaceship, which is mostly made up of a force field containing a breathable, earthlike atmosphere. There is a constant outward pull of something like 0.3 ...
Executive Summary Thank you for considering Chronograph Talent Consulting for your talent acquisition needs. We select the best talent from all previous periods of human history and make them ava...
In a universe where humans can take elective surgery to render themselves ruminents, what would be the effect of that surgery in regards to weight? To keep things simple: The surgery involves th...
I have been thinking about which mutants from Marvel are most realistic and Zeitgeist comes to mind. Long story short, his power is weaponized acidic vomit. He can spew it a few meters away at will...
I've got a group of magical people living mostly incognito in an ancient society. They look and act exactly the same as regular people, but they are really magicians, and a side effect of having th...
It's been said that sweating is the human way of shedding off excess heat. But to do that requires a loss of water, which makes the overall sensation miserable and uncomfortable. Are there othe...
So, a visitor (whether they be from another planet or another reality) gets deposited on the face of the Earth. They find that the air's breathable, that water and suitable macronutrients are avai...
Suppose that there is a species of dogs that are much more intelligent than humans and can speak. The humans know that the animal is smarter too. The only reason these animals can't rule over human...
Could humanoids similar to the cubic-based beings found in Minecraft be physically plausible? The requirements are not that human can take such a shape, but rather that a being of such size and sha...
The title is pretty self-explanatory. How powerful does a computer have to be before it has the hardware capability to simulate and emulate a human mind in real-time? I'm leaving the question of ...
How dense would an atmosphere (that's presumably non-toxic) need to be in order for a human being (without wings, artificial or otherwise) to achieve unassisted flight (without killing said person ...
I am currently working on a world with a "human" species. The planet is similar to ours and these "humans" would evolve in a similar environment. I know that bio-luminescence appears mainly where ...
