So I have a story about humans far off in the future on a different planet that have evolved to be more in tune with electromagnetism and magnetism. Their technology mostly works because of magneti...
The older man looked at the younger one. He took a deep breath and began to tell his tale, just like he was told before when he himself was that young. I've been here way longer than you, let m...
Friends, Many years ago"”in a book about building space stations"”I read that humans can thrive and maintain enough bone density and muscle to successfully reacclimatize to live at 20% Earth's Grav...
Spaceships are a peculiar thing; as are the things inside them. Humans... Humids... Humies - the colloquial term for those crazy enough to make a living by crewing these hulks of metal. A special b...
In the History Channel program Clash of the Gods, some of the highlit characters have been given some interesting physical liberties. The episode "Minotaur" features King Minos with a meerkat-like...
Although the fossil fuel coal had been used as a fuel since 1,000 B.C., it wasn't until the arrival of the Industrial Revolution from the mid-1700s through the 1800s that coal began to replace b...
This is possibly not quite the right place to ask this question but it's fundamental to the world I'm working on so here it is; if faced with a potent existential threat, in the form of an outside ...
Is it reasonably possible for a type of human to exist that rapidly tans in the presence of large amounts of sun/radiation and loses it again afterwards, in a matter of minutes? Also, how might suc...
Imagine a character with a healing ability similar to Wolverine or Deadpool (as in able to recover from most injuries in minutes). The ability is always "on," and works like a sped-up version of th...
I am working on a story where ships are tricked and crash land on a volcanic planet due to some sort of electromagnetic interference. The survivors of the landing essentially become gladiators on ...
If all the fresh water were at least 25% deuterium, would humans be able to survive? Would there be significant other detrimental side effects to human physiology as a result?
I'm imagining that a group of humans was transported to a different planet almost 100 thousand years ago. The planet is similar enough to Earth that they can survive, and already had other earth-...
I have built a Tchou-Tchou 'hyperloop' wagon that reaches 310Â km/h on a 500 meter test rail. One of my investor customers wants to try the Tchou-Tchou, but I am a bit concerned about his safety. T...
So, normal humans can tolerate up to 4g of acceleration. If I had the tech to freeze and thaw people, would being frozen aid in tolerating high-g forces, or would the brittleness of your froz...
I remember reading Tarzan by Edgar Rice Burroughs. The protagonist is a an extremely strong man, capable of hand to paw combat with lions. The origin of his strength is attributed to living among g...
I'm looking for answers that focus on changes in internal anatomy that allow humans to survive in a high-g environment. If dramatic visible change can be avoided, that'd be great. Problems Circula...
A mad, egomaniac, scientist has developed a way of extending the natural growth of humans to create an army of 20ft (6 meter) tall soldiers. Physiologically, they are three times the size of norma...
The Average Human Achieves IQ Scores 60 Standard Deviations Above The Average Person of 2016 By the time the year 3016 rolls around, the human race for the first time ever has achieved an average ...
What would be the effects of high or low gravity on human body development? How would the human body develop under a different gravity? Many science fiction stories explore the idea that people fro...
In a non-magical world where homo sapiens has evolved into several races or breeds (like dogs) or even species as in Q10102 and Q12190, that can interbreed for the most part, how can one model the ...
Question simplified and clarified as requested... thanks for the feedback! If humankind evolved on a planet with a consistent, gentle environment, would it negate the need for them to develop varia...
Let's suppose regular humans (same intelligence and pretty much same features) but they usually have 3-6 babies at a time. To me, many breasts seem like an evolutionary disadvantage. Something you...
(Perhaps termite people would be more appropriate) In my world, the Gbajumo (think race of semi-gods) decide that the humanoid beings of the world have become too cocky and comfortable in their su...
Imagine that the average number of children born per birth without any artificial intervention was three (i.e. triplets were the norm) and that 98% of pregnancies gave rise to 2 to 4 children, with...
In one of my more recent questions, one Xandar The Zenon commented that a mutation that creates the gene for red or orange pigmentation on the human skin is more likely than green, blue or purple. ...
I need a planet where the day cycle is short, in particular 16 hours. I read What determines the length of a day on a planet? and Is it physically possible for a planet to have seasons of different...
This answer states that "guided evolution" would help babies develop under constant 3-4g's. This answer has inspired me to ask , what sort of genetic tinkering would help humans adapt to life on a ...
I know that humans can naturally have more than 1 hair color, whether that is in a transition from 1 color to another or they are born with it. Like for example there are babies with both red and b...
I recently came across this paper detailing a plan to use 12 superconducting rings around earth to strengthen our magnetic field. I'm planning on using this same idea for my own worldbuilding. An ...
For space travel: would you need to recreate earths air composition? Or could you just get by with the top 2 or 3 main components, i.e. either 78% nitrogen and 22% oxygen, or 78% nitrogen, 21% oxyg...
Is there any combination of factors that would allow the average human to walk on a cloud without the aid of magic or technology? If so, could buildings and cities be constructed on clouds in those...
Supposing you took Earth or a planet like it and doubled its mass, the gravity would obviously increase in whatever proportion to that. As a result, humans as we know them would be ... thicker, (...
It is late in the day, and humanity has made the fateful step: digital transcendence for some. The last few weeks before the Singularity were singularly chaotic, with widespread violence by opponen...
In Can I significantly shorten the days on a planet that can support human life? I asked about changes needed to a planet to support human life with a much-shorter day (12 hours or so instead of 24...
Logically a born and raised on a planet with Earth-like gravity would move slower on a high gravity planet, and would be both faster, and possibly clumsier in low gravity. In my world humanity has ...
How can a part of a continent (super or other) remain unexplored by the apparently civilized majority? The undiscovered part must be habitable but inaccessible, by land or sea, so that the rest of ...
My generation ship aliens have 2 thumbed hands. No, not the 2 thumbs on the same side that some humans have but the 2 thumbs on opposite sides. So it would be kind of like this: Except more rept...
The Snakebot of Doom - now dubbed Jormungandr by the first humans to encounter it and survive - is busy steamrolling New York into rubble, having first nuked the capitols of every member of the Nuc...
Some Details Suppose an Earth-like world with the following changes: Atmosphere: 67% nitrogen, 31% oxygen, 2% other Average surface temperature: 16.7° C (62° F) Day/night cycle: 20 hours Gravi...
This question is focused on a purely chemical messaging system for humans that provides the same degree of nuance that spoken human languages convey now as well as all the information that smells c...
Short variant of question: I have few big natural caves (really big). I want to transform it into shelters capable of keeping ~2.000.000 humans in hibernation, sleep, suspended animation or othe...
Some of our ancestors were more robust than modern humans. Could they adapt to a 2-g world better than we might? Maybe even 3-g? Over time their bodies could evolve, i.e. only the most robust wou...
I'd like to know if a planet without any animals except humans can exist. The cause of this absence of other species could be anything but the humans should not have any social interaction with som...
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...
In the future, humans decide to conduct a long term experiment in which they make robots that move and think exactly like humans. They also need to eat, drink and breathe the same as humans. These ...
If I'm writing a sci-fi story and I wanted to include humans with modified eyesight that see into the ultraviolet and infrared bands of the electromagnetic spectrum, what would I have to change abo...
We're in a military space cruiser, designed for in-system patrolling. We're selected to test out a prototype FTL drive. The initial tests are supposed to be short-ranged in-system hops. A disaster...
Imagine a meta-human, one engineered to be immortal. A combination of cybernetic enhancements, genetic engineering, and other scientific modifications have made it so this human will not die from a...
I plan on writing a story about a human born in the wild and raised by wild animals. I have heard of stories of real humans being raised by wild animals, mostly in Africa. I have also done some res...
Humanity has been exposed to prolonged nuclear radiation for thousands of years. In the past, hundreds of nuclear bombs dropped; then nuclear warfare ceased for thousands of years. Assume that hum...
