Is it plausible to assume that the total amount of water (edit: water molecules) on planet earth was, in different periods of earth's history, significantly lower or significantly higher, or rather...
This is a follow up question to Sky of Earth and Seas of Sky I have a medieval fantasy setting where people live in a vast expanse of giant caves contained in a sort of giant Stanford torus. This...
Premise/question Hydraulic mining is the process of spraying high-pressure jets of water into the ground to dislodge sediment and rocks. The muddy water from this is directed into sluices where va...
Something like the above (Natural Springs by Ellie Cooper) - either where the water originates from atop the tree through regular rainfall, or is directed up and into the tree via the spring (or ...
Many planets out there will be water worlds. Those generally come in two flavors: either the oceans are so deep that the water turns into high-pressure ices like ice-six, -seven, -ten and -eleven o...
The fleet in my setting are forced to leave the planet due to a volatile virus, and leave in pre-prepared spacefaring vessels capable of transporting ten million people per ship. The ships have alg...
I am creating an RPG and came across an image that I wanted to base my landscape on. It is shown above. Is it possible for terrain like that to form on Earth (ignore the wildlife)? If it is, how ...
Based on the planet from this question. The main thing that distinguishes this planet from, say, Europa, is the handwavium light-source, which I must assume is wrapped in a perpetual explosion wrap...
If we assume a terraformed Ganymede has a global ocean roughly 800km deep, that food is bountiful, and that it has been populated by a variety of life from Earth, how large could these creatures gr...
Imagine similar earth conditions of oceans and currents, and a renaissance type kind of ships of various sizes (ranging from sloops to ships-of-the-line), could a fleet consisting in 1500 (aprox.) ...
Landia, a land based civilisation, has recently established diplomatic relations with Aquatica, a civilisation of fish people. The two peoples exchange gifts to each other - including from Landia, ...
It's easy to imagine how would a water-breathing aquatic race outfit its spaceship - take a normal spaceship, insulate it, fill it with oxygenated water, possibly add some enhanced turbines to pump...
While reading this question about how non-primate mammals could develop a bipedal stance, I became curious about the broader reasons why animals could evolve to walk on two legs. I found some insi...
A certain imaginary stellar system had once a water world. But instead of evaporating away under the stellar wind, this lucky (or unlucky?) water world (made of only water and a gaseous atmosphere)...
Take a torus planet: It has the structure of a normal planet (ours): The diagram is not to scale. Assume similar proportions of Crust:Mantle:Cores as the Earth. Is has a similar volume (close...
Is it theoretically possible to extract all ice and water from moons with subsurface oceans like Ganymede or Enceladus? What would the consequences of isostatic rebounding be if this was done on ...
Imagine that when Christopher Columbus sailed West in his Carrack to travel around the world to reach India, he had never made it to land, because halfway across the Atlantic Ocean between Europe a...
On my Conworld, the oceans are purple. This is mostly for aesthetic purposes and my current explanation is an abundance of cyanobacteria. I'm not sure that this explains it correctly, so what could...
Hopefully this isn't two separate questions - I do feel like they are interconnected enough that they can be counted as one. I'm wondering if it would be possible for primitive human ancestors. Le...
Just as in the real world where horses were tamed to travel long distances quickly across land, would it be realistic for an animal to be tamed and used as an aquatic mount for quick transport arou...
Water, as is, with its physical and chemical properties, is the base of any living being on Earth. Water has a rather high specific heat capacity of 4.184 J/gC, which in itself has a great effect ...
A radical shift in the Earth's orbit has made the Earth much colder, with all the oceans freezing over, and the atmosphere liquifying and falling as rain. Humans live deep underground in areas of h...
This is strictly Earth based. Would it be possible for a society to develop their own civilization underwater (nothing fantastical like Aquaman or whatever, but more of a grimy, hardscrabble existe...
Assuming the same rules for physics apply to this world as they do for our own, how would a humanoid race that lives at the bottom of the sea be able to walk around like humans do on land? What kin...
Recently, I found this map of Africa's paleolakes in the Imaginary Maps reddit: Finding this map was mere coincidence, but this map definitely interests me. Now there have been multiple what-if...
I'm trying to create basically realistic mermaids, and working on developing body language and vocalizations. I have most of the vocalizations I can think of (suggestions are still appreciated), bu...
It makes sense to me that the best food in an underwater dome complex would be fish. Considering the massive amounts of aquatic life in the vicinity, it could work pretty well. However, I can't th...
Planet: earth like, half the radius of earth, gravity is .7g. Assuming this is possible and humans live on this planet, would it be possible to have 90% of the planets surface area be under water?...
First of all, yes I'm Australian, and yes I am using a kangaroo to type this up. If you take a look at Australia, it's a pretty sad place geographically. Very flat, very dry, mostly desert and for...
In this world, a progenitor has created a mass of order out of chaos, with the possibility of entropic fluctuations increasing the further out from the center you get. What do I mean by entropic fl...
Suppose some magical civilization on Earth-like planet can create portals. Any given portal entrances are spherical surfaces of the same radius. Any particle enters one sphere and exits another in ...
One way, I think, is if the gravity is exactly correct. However, while I think the water might be in a unstable equilibrium, I have been unable to work out the mathematics. Let's assume that such a...
Suppose that there was a tribe of nomadic mermaids whose lives were primarily centered around following pods of dolphins to eat. They live in the equivalent of the frigid antarctic seas. As they ...
I was thinking of an alternate history, in a part of a civilization, living along the Eastern Mediterranean, during the Bronze Age moves to the sea floor to found an underwater civilization. They ...
Two rivers converging into one is obviously extremely common, most often when one is clearly dominant over the other (whereby the lesser one is the 'tributary' of the greater) but also sometimes wh...
I'm writing a drama book and it's meant to be taken 100% seriously, and the main character was born with an allergy to $H_2O$. She does not have Aquagenic Urticaria, as that only affects the skin. ...
I am trying to wrap my head around the geography of a settlement in my world. The settlement is situated along the coast, along a river roughly 500m wide with temperate mixed forests surrounding i...
I'm interested in creating some construct of a society in the Twilight and Midnight zones of the ocean. By what means could they mine, farm, and trade in what is suppose to be a more futuristic so...
I want to put a story in place where a country lived underwater, and I am wondering of its viability. Here is the world description: It is a square of 100 km*100 km on the ocean with the weather ...
I'm writing a story that takes place entirely underwater, mostly in a deep sea town and shallower city. Both are underwater and populated by beings who can survive underwater. My thinking is that...
In a vaguely Medieval setting with some limited magic, how would an underwater city handle sewage? Sanitation was one of the biggest limiting factors in the growth of human cities, and being under...
I'm working on a sci-fi setting which includes an aquatic space-faring species. When a human space vessel is ruptured and depressurizes, the gas can escape rapidly and we immediately suffer from t...
This one is rather straightforward. A character falls into a magically-induced coma for about 10,000 years and then wakes up to find the world around him different in quite a few ways. There's not ...
Let's assume that there is a lake that has formed from snowmelt and rainfall. The lake has never been in contact with other bodies of water. How might this lake become a complete ecosystem?
I don't wanna reveal too much about my world, however, the basic idea is that there is a town of people who live deep underwater (they are biologically capable of doing underwater gas exchange and ...
Handwaving the origin of one such place, imagine a universe where every part of space is filled fully and evenly with liquid water (at, say 1 degree Celsius). What would be the experience of a soli...
A soft and vulnerable intelligent underwater species, you can consider them closely related to Earth's octopus - in the way chimps are closely related to humans. Consider that clothing is often wo...
I am creating a speculative evolution project for school (and partially for leisure) and I need a planet for my organisms to live on. I have a rough idea of what it may be like but I'm no expert in...
With the rise of global warming and our leaders not seeming to do enough about it, expanding our ranges past the earth's ground seems like something we must do eventually. Everyone always points to...
I have followed this forum for quite some time. Now is the time to ask my first question :) I'm currently working on a story in which a future, civilian luxury submarine is used to research some li...
