One of the points made in a number of recent questions regarding underwater races has prompted me to review one of my older pieces of world-building. Namely: the difficulty of producing common stru...
Here is a link to the water canopy theory. My question is: how this water could end up there, high above the surface? I was thinking about two possibilities: a comet spreading ice/water as it pa...
I read somewhere that the lowest depth for a sustainable underwater habitat is estimated to be three-hundred meters. Any lower and the pressure becomes too great for structures that are currently w...
You've got to love the rainbow, it's an awesome sight. But I don't want humans to have the pleasure of seeing the rainbow. What change to the earth, atmosphere and so on, is needed so that humans ...
Taking genetic manipulation of humans to change them to live in other environments, besides maybe gills what other physical changes would need to be done for a human to spend 95+% time living in th...
After circumstances make the shallow water in the oceans uninhabitable, great white sharks retreat to the deeper parts of the ocean, about 600 feet down (182 meters) to survive. The sharks can not ...
Another user's answer to a recent question, specifically the way it was worded, gave me a vision I cannot shake. Our intrepid adventurer, Joe A. Venture, is making his way through a subterranean n...
Following on from this question and assuming the race in question had developed the ability to create tools how would they approach the need for mass calculation. Our early computers were used to ...
I was thinking about people who once told me that I must feel the rain earlier than them (I'm tall). So I thought of a world where the rain falls so slowly that the humans of different size living ...
What can cause water to be foam-like, in lumps, but still liquid? Something similar to goo (jelly like but liquid and opaque)? I have a planet and such kind of water, which is drinkable and the te...
Let's say there is a city, about the size of New York City, that is made only out of stone, steel, and glass. This city would be completely underwater. Assuming no humans are alive in this city, ho...
I'm trying to build a world that is almost completely water, but I couldn't come up with an explanation for WHY the world was like this. The world has the same gravity and atmosphere of Earth. It a...
On another world, there is giant ravine leading into a cave where a sentient species live (Let's call them Cavers). They have limited access to materials; the only resources they have are rocks, m...
Many worlds have an apocalyptic/cataclysmic event. If mine is a Great Flood, how long would it take for much of the world to be habitable land again? Keep in mind, by the events of the present, the...
Let's say I'm an extremely rich and somewhat secretive research group who wants to carry out experiments and such away from the prying eyes of the public. One of the obvious ideas for the location ...
I am working with a story. I wish to make my story somewhat logical by adding some science and thereby not making it to appear fantasy. This story is on a fictional planet far away from Earth. Let...
I have a planet where the equator temperatures are near boiling point (90ËšC or 194ËšF) during the "summer". What qualities would an animal need in order to survive these kinds of temperatures to c...
Anatomically speaking, could an aquatic mammal develop a horizontal fin that instead of being localized at the end of the tail extends up the sides in a similar manner to how an eel's fin extends u...
I was making a planet for a game and I was wondering how the world would be affected if it never had salt water, but instead a huge fresh water supply. Then I thought about what it might do to the ...
I previously asked What measures might an ancient civilization take to protect itself from extreme heat? The answers gave some useful suggestions as to how cities could be adapted. For convenience...
Following on from my previous question here concerning the ancient civilization I have called the Androy and their struggle to survive terrible drought conditions on their planet. After years of s...
It is still a myth as far as our modern civilization is concerned, Atlantis located somewhere within the devil's triangle and it's inhabitants had struck down many planes and vessels daring to dist...
I want to design a creature capable of surviving long periods without drinking water, but I am not sure how that creature could store water. These are my ideas but I am looking for something more e...
Imagine there is a micro-city built on the ocean floor in the pacific ocean covered with a durable dome with a 1 mile radius to keep water out. At this moment let us assume that the dome holds up b...
In my Pathfinder RPG campaign setting I have two continents separated by an isthmus. An artificial canyon carved through the isthmus from one ocean to another divides the continents. The canyon i...
In a solar system much like ours, would there be the possibility of a planet of our size that would have lakes, rivers, oceans, etc. that would be composed of either a mixture of water and ammonia ...
In a different question, someone mentioned "technology dichotomy", where they said "you can't invent time travel without first inventing the wheel". Then I read the question In a society of flying ...
This is a world with underwater merfolks and other humanoids. They have opposable thumbs, so they can use tools humans can use. Lets assume there's different subspecies and races of these merfolks,...
I'm trying to build a setting in which humankind would have no other choice than to live underwater to survive. Suppose there was a nuclear war in which a huge part of the human population died, ...
I'm considering the mechanics of a "shock and awe" scene in my novel which could see an old dam being brought down. The era is equivalent to that of the middle Roman empire, so introducing explosiv...
BACKGROUND: I have been working on a game called Rise: The Vieneo Province. Vieneo is a terrestrial moon (all details can be found here) but we have an atmospheric composition we arrived on from ...
I need you guys to help me out here. I'm developing clothing ideas and I need to understand what animals and plants may be used to create such clothes. Part of a story that I'm creating is a wate...
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?
This might be a little difficult to explain, but basically: the concept of "atmospheric ocean" is a gas that is found pretty much everywhere on the planet. Probably very dense and sinks to the surf...
I'm brainstorming for a rocky planet with similar mass to that of Earth's, orbiting a red dwarf star. It is tidally locked with no natural satellites, yet I'm bent on having liquid water on both su...
I am writing a DnD module where fishmen are invading island nations. The islands would naturally have adapted to this in some way as the raids have been happening for years. What method would these...
So there's a planet that is used as a farming world (food) for its system. This planet has a single, Mediterranean sea-sized ocean on it and lacks any other major surface oceans (he hasn't excluded...
There have been more than a few questions covering Alcubiere warp drives, many about what happens with one at FTL and a few about using them at sub-light speeds. I'm curious about what happens at ...
Ice is strange, in that the solid form is less dense than the liquid water it freezes from. This causes Ice to float on top of the water. How would our planet earth be different if something chang...
Since fire doesn't burn under water aquatic alien sophonts will use alternative technologies. The question is, which alternatives to fire can they use? I am interested in all aspects of fire, (hea...
Is it possible for under water Atlanteans to make explosives? These Atlanteans have no magic but do have gills. They look like normal people other than the gills and webbed hands and feet. They...
Assuming the ocean is deep enough and not overcrowded is there any upper limits to the size a "sea monster" can grow? On land creatures are limited by gravity, they have to be able to generate the...
I am working on a scenario where a climate protection organization tries to breed sapient Cephalopoda as a help in their fight against climate change. The breeding goals of the evolving species are...
Question: Could a planet contain all of its (vast) oceans underground? I imagined a planet with no surface oceans - and no water cycle above ground - but where life was still possible. My initia...
Defining what is a super intelligent civilization: An industrial civilization that invest on scientific progress and that builds and manipulates computers, robots and nano-machines, has effi...
In the answers to this question I learned that some cephalopods communicate via color: Some cephalopods are capable of rapid changes in skin color and pattern through nervous control of chromat...
I want to develop a water-dwelling, intelligent species that could ultimately reach space.1 My question here is about the biology of such creatures. I want my creatures to live in the water, not ...
In most representations of mermaid cities, they either live in implausible magical palaces, or in some more or less elaborate cave systems. Assuming the only difference with our world is the prese...
I have a bomberplane capable of carying a nuke. A large nuke. Let us say that I don't like the idea of wiping a city from the face of the earth. Instead, I decide to mass-produce solid CO2, and dro...
I was wondering: what if a planet (such as earth) suddenly had all surface tension removed (mainly in water, because all carbon based life forms need it.). What would happen?
