I am aware of biological constraints to our size, such as the issues presented by Vsauce in this video. However, letting the biological factors aside, what is the perfect size for a technologicall...
Answer this question: "What would happen to a high-pressure creature in a low-pressure atmosphere? The hypothetical creature has evolved on a planet with an atmosphere that's much more pressuris...
The hypothetical creature has evolved on a planet with an atmosphere that's much more pressurised than that of Earth. It's humanoid in appearance, in that it has two arms and two legs as well as a ...
The situation: A planet largely composed of water, with land masses being island chains scattered planet-wide. At all times there is precipitation of some sort, whether it be snow or rain based on...
In the question; Hollow-boned Humanoids Nathaniels humanoids were a flying mammal species called soarfolk. But let's say that I want a sapient mammal to have hollow bones but not fly. These furred...
I'm thinking of a planet incredibly similar to earth. It's located in a solar system where everything is 1000x bigger than ours. The sudden turn to this is that humans aren't scaled. The Earth ha...
My continent features a large canyon, perhaps 100 miles long and mile across. It is deep enough that descending to the bottom is dangerous and impractical. It is located primarily in an arid scrubl...
Could a humanesque creature derive all its nutrients from drinking blood? Would a vampire get more energy, warmth or nutrients from fresh blood as opposed to frozen? What about fresh blood vs. old...
Okay, so I'm a fiction writer and I love neo-futuristic tech, but when I write I like to be as realistic as possible. One such technology, which I'm thinking of using in a fictional series, is the ...
For my current purposes, assume we have two planets identical to earth. So, could two of these planets form a stable binary system, and still be close enough to see the green foliage on the surface...
Say an early human civilization is arising on an earth-like planet (Earth, in fact) with one notable difference to the sky: a small ring of debris orbiting the planet. Assume the ring is clearly vi...
(I have tried to fix this question as best as possible with the help provided from the staff of the site.) I have started to develop my own crustacean species that resembles ants slightly. I would...
I have an idea for a planet that orbits two stars. These starsslowly orbit each other, have equivalent masses/sizes, and while one is slightly red, the other is slightly blue. When I talk about the...
Long ago, I made a post with a scenario on how planet Earth would be affected if our moon were the size of Mars. But I've decided that it be more reasonable if our moon were closer in size to Tita...
To avoid being too broad, I'd like to use the portals for purely altruistic purposes (health, environment, safety), and not for scientific or military acheivement (e.g. - not an instant space eleva...
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 ...
Could a humanesque creature derive all its nutrients from drinking blood? One of the linked question's answers talks about the vampire becoming a filtration system from humans, could the vampire f...
A few definitions: permanent - not permanent on the scale of the Earth's lifetime, but good enough to last a couple hundred years - seeming permanent to those who were born there at least. size o...
How much blood does a vampire need? Could a humanesque creature derive all its nutrients from drinking blood? Both these questions have some good answers and my question is based off them both......
Other blood colors The link about talks about other color's of blood that could be if made with either different metals or different oxygen carrier's. What I want to know is if you mixed iron bloo...
I was just wondering how would a humanoid like Ant species develop communication. I know how they communicate with each other in nature using pheromones and touch. Would it be possible that this sp...
Would it be possible to produce a pair of human brains that are connected by a wormhole that has each end inside one of the brains? What I had in mind is that the wormhole would have neurons insid...
So, after multiple users informed me that my previous question was a little to broad, I decided to narrow my focus a little bit. Using only hard science, could there be a planet composed, with the...
So as an experiment, I took a bunch of machine learning algorithms (neural nets, genetic programming, traditional optimization, etc ...) and connected them in a mess of reinforcing loops, along wit...
Space exploration is great and amazing, and I want my fictional US government to fund it to the tune of $1 trillion per year, instead of the (comparatively) meager \$17.5 billion it is getting now....
