Carbon dioxide turns supercritical above a pressure of 73 atm and 304.25 K (31.10 °C). The surface of Venus fullfils these conditions. The density of the air at the surface is 67 kg/m3, whi...
This linked video explains who and what Dr Manhattan is and what are his super-powers Dr. Manhattan's Superpowers EXPLAINED. Dr Manhattan character is from Watchmen Here some quotes from Wikiped...
As the title says, what modification is needed, so a creature cannot fart while still being able to excrete their waste? So creatures that can't excrete or doesn't have an anus like the Demodex i...
As the title says, Is it possible to map the firing of neurons in the human brain so as to stimulate artificial memories to the amnesiac person? This is based on this similar question; Is it possi...
A bit of backstory: I'm attempting to create a militaristic alien race composed of elite warriors capable of conquering the galaxy. They posses a variety of "enhanced" abilities such as immense str...
If this hypothetical moon were to come to exist between the Earth and Moon, how long would it survive? And could it transition to the moon's orbit, as a subsatellite? To clairify, this scenario is...
What type of climate would I have to have to face a perpetually foggy forest at the base of a mountain range?
I'm looking to design one of my warring planets around organolithium chemistry with seas and precipitate primarily composed of a clear organolithium solvent liquid - possibly ammonia. I've searched...
I know there are examples of land vertebrates moving back into the oceans, such as in the case of whales, and marine reptiles, but in every case that I know of when a land vertebrate moves back int...
Civilization is fairly young in my setting. Thus, the sheer number of ruined buildings and abandoned structures, found throughout the wilderness, seems strange. The ruins vary a lot: has-seen-bett...
So in my world, the main Antagonist has the ability to drain the life from things around her, turning them to stone in the process. That made me wonder how organic material would erode if it were p...
Would abnormally high levels of cobalt on a moon cause it to appear blue to those on the planet it orbits?
In theory, could any organism using protein folding or another biological process "assemble" the diamond allotrope of carbon, if it were at the correct pressure to do so? In other words, could some...
In an alternate Earth, a mass extinction wiped out a percentage of the most successful phylum ever--Arthropoda. All that survived of the class Arachnida were the really small varieties--the ticks,...
Imagine a VR headset with built in camera & AI with object recognition & photo editing software. The camera records the image. The AI is trained to pick out 'undesirable' images, objects,...
I'm working on a completely flat, underground world, where "world" means "universe" rather than the equivalent of "planet". Here's what I have so far: The world is a flat, apparently infinite (in...
The mad scientist community is...mad, to put it kiddie-appropriately. Their logic has the tendency to make 0% sense 100% of the time (provided, of course, that they ever bring it up.) So you can ...
My aliens want to build the heaviest chemical rocket possible: They never were much into space travel, since their planets' gravity is about 1.5 of ours. They made lots of bad experiences fighting ...
This question hopes to make a space tug crew's life tolerable. A supply pipeline links two civilizations. Due to the long travel time between the ends, cargo is "thrown" at the other side in unman...
I have been making a future colonization scenario where people have vast colonies on Mars and cloud top bases on Venus. These things are unbelievably large. I've already thought of a way to travel ...
The island of Themascryia is a nation of amazons, an all-female race that spend their lives training for battle. They are currently under siege by foreign invaders. This army comes from a powerful ...
On a planet with a geostationary moon, how can I determine the position in the sky of the moon depending on the position on the planet surface? For example, Pluto's Charon. The moon wouldn't move ...
Physical transformation relies on evolution, which typically works n the scale of millions of years and in accordance with environmental needs. However, is there any plausible way maybe through th...
I am working on a planet were life (trees, plants, food, animals, humans) would be bigger/taller than Earth. I have learned that oxygen level or gravity, for example, could help change the size of ...
