In a post-post-apocalyptic world with adequately schizophrenic tech, a tinkerer decides to build a submarine engine around a lump of radium, or some other reliable source of heat. But instead of us...
I'm currently trying to set up an underwater race in my world"”merpeople if you will"”and I'm trying to figure out how their city would look. I'm basing their religion and lifestyle on native civil...
My mermaids have returned, and now they're dragging semi-conscious people about 700-ish meters underwater. Is it realistic for the person to still be alive at this point? (Y'know, for about ten sec...
Suppose, that in a particular area of the ocean on an earth-like planet, all water molecules are transmuted into an exotic variety of $H_2O$ that is identical to normal water in every way except wi...
For my world I would need a really large swamp (or similar kind of wetland). It should be about 200km in diameter, which should be quite possible given a large enough flat terrain and enough rain. ...
Imagine a planet orbiting a star some billions of lightyears away from us, the planet is 4 times the mass of Earth and is covered with ice 100km thick on average. It is believed that liquid ocean e...

Is it possible for a planet to have a liquid ring rather than a ring made of solid particles? If it is, how long would it be stable for? If not, is there any other configuration of a liquid that c...
Humans lay road to gain fast access to distant places until aeroplane is invented, I would presume the mermaids living underwater can make use of the strong water current to get around the ocean qu...
Right now merfolks are totally envious of us watching a live stream video of cat(fight) via WiFi or satellite internet, ok ok I get it's not the speed but its latency... Urrrr. Nevermind that I sin...
A habitable (human could survive in its atmosphere without suits) desert planet which used to have large oceans is quite common in ScFi. I was thinking about the processes which could have been res...
A generation spaceship (a spaceship designed for multiple generations of humans to live in) could sail through the galaxy for hundreds of years before finding another planet, let alone a planet wit...
Whales and dolphins surely do not have ears similar to ours and yet they can pick up ultrasound underwater without fear of water pressure damaging the eardrum. Any idea how the mermaids with ears l...
Let's use the sea turtle and the terrapin as an example, need I say more? I used terrapin because like the mermaid which is half fish and half girl so a terrapin would serve as an excellent example...
I must admit this legendary or mythical creature is really fascinating and I am talking about the half fish half woman. I know most fish have the ability to control buoyancy as they can easily mov...
So this is a small map of all the continents on the small planet of Parsas Decem. As far as most of the rivers go, I've got it figured out. What I'm wondering is, can salt water flowing in from t...
There's a planet called eaglypt whose surface is 100% barren desert. However, there is a twist: the planet's core consists of liquid water, and there are a few places where this water seeps through...
I have a race of octopodes with the same intelligence distribution as humans. I want them to "colonise" land to a similar extent as we have "colonised" space; have regular transport between the oce...
I've got a species that lives in the Southern Ocean along the Antarctic coast, and they are basically a sentient crossbreed of Orca whales and elephant seals. They are omnivores, have opposeable th...
I'm trying to create a planet which environment is not immediately lethal to humans, (reasonable oxygen level) however after closer inspection turns out not to be specially Earth-like. One issues ...
Aqadatio is a planet which is completely flooded. This flood was generated by its own government to get out of debt (long story). The inhabitants of this planet are technologically advanced, more s...
My story takes place hundreds of years in the future after global warming has made life at the surface uninhabitable for most life forms. What's left of mankind survived because it became popular t...
before I get into my question I wanted to thank everyone for their input in my first thread about the general principles of river drawing. I have taken your comments under consideration and began r...
I'm new here but I've been a worldbuilder for the last decade or so. I'm pretty late to the 'mapping out your country' party and I've only been at it for about 8 months, but I'm starting to see som...
First of all, I tried to look if this wasn't answered before. Found this and this but neither is exactly what I need. Some Context There's this race of humanoid fish people. They live in cities b...
You have an underwater civilisation, be they merpeople, octopus people, partially evolved humans or not. One thing that is always considered as a necessity in the development of any society is mini...
Looking to how I can make Nagas and Mermaids able to exist and evolve in my story, I came across this post which explains how Nagas could evolve from humans: Anatomically Correct Naga In the top a...
In my colonizing business, some colonists build a underwater base on a all-about nice planet. They are using food storage right now; but now they need to start farming. Ive looked up some farming t...

Reading questions of How much TNT needed to blow up Mount Everest and the Moon - and especially the comments below it, I have to ask it: Can we blow up the sea? Detonating atomic bomb undersea ma...
In a world I'm currently developing, I'm working on a merpeople equivalent (more or less physically identical to your bogstandard mermaids, for the purposes of this question), and I want them to we...
tl;dr : the earth has been gradually flooded, over the course of a few hundred years. Also, there are now large lumps or ice raining out of the sky (not very often), causing massive tsunamis. I ha...
Let's pretend these magnificent and beautiful creatures are able to reproduce asexually so we can forget about their mating habits or their partners. I have yet to witness any hard shell eggs laid...
Assuming a situation similar to this, where the moon causes slower but massive tides that slowly encircle the globe. Would the poles be constantly underwater or not underwater (like A or B below)?:...
In the world I'm building, there is a single continent. However, in the deeper parts of the ocean, there are hydrothermal vents. They're pretty necessary to my story, but I can't figure out why the...
Imagine an Earth-like world in all respects except that the Moon is much much closer. I think I'm right to say if the Moon were very close that tidal forces would slowly rob it of momentum and it ...
What examples are there in science fiction of molecular shields that can cancel out or "eat" certain molecules--and are they plausible? Is it hypothetically possible to create a giant levee that is...
In my fantasy world, there has been a longstanding presence of underwater civilizations, both alongside and independent of surface-based kingdoms. In the style of Tolkien's Beleriand, various conti...
Is there a way to design a river system in an O'Neill/McKendree-style cylindrical habitat to passively feed into itself in an endless loop, from one end of the habitat to the other and back again? ...
I rediscovered this article recently and loved all the creative answers on how a mermaid might build underwater. This, for me, brought to mind Atlantis, the kingdom that sank into the sea. I've...
We currently have jet engine in flighter jet, space shuttle, some race cars but nothing underwater where breaking sound barrier(air) is concerned. I'm imagining in near future many manned electric ...
So we all know that the majority of sea creatures use fins that move either from side to side or up and down to propel themselves. But our boats don't do that. Our boats use propellers - a rotatio...

Context On my world, there is a lot of water: sea, oceans, ... There are also firm land and islands, so it's interesting to travel on the water. The problem is that there is NO wind at all, and lo...
