Could underwater creatures with the intelligence of human cave men or possibly the intelligence of apes create technology (that is, more complex technology comparable to what we have now rather tha...
An aquatic creature made of a yellow goo moves through the water by moving its body like a squid. The goo can slowly dissolve small creatures and the planet's form of seaweed/kelp. It also has an a...
Imagine a sentient species with these attributes: not very advanced (think primal tribes) can breathe underwater good swimmers feed on seafood (fish, algae) live in a high fantasy world with orcs...
In an answer to this question Cyrus suggested that pre-technology merpeople might use shrimp or prawns in lue of maggots to eat away rotting flesh. Similar to how plants and (in some cases) anima...
We all know that lightsabers are used for cutting/melting through lots of types of materials (with few exceptions). Now what will happen if lightsaber is dropped into a lake and stays on? Wha...
Electricity pervades our daily lives, and makes possible a lot of technological achievements. Harnessing it helps the development of any civilization. The thing is, water - especially sea water - i...
There are a few million cubic miles of water trapped in the ice-caps that line our planet's poles. If all of it were to melt in a matter of a few short years (somehow), London would surely be left ...
I gave this a quick test on sandbox, and agreed with the comment that I should steer away from the physics part and focus on the geology, etc. Assuming Europa's ice crust is 10km thick as some spe...
I have a species of creatures that live in packs off the coast of my fictional world's one super continent. Humans have lived there for millions of years. At one point these humans had achieved the...
Unless of course the mermaids can use "super" low frequency like our subs, but wouldn't the quality become poor. How can the mermaids enjoy 4K quality digital TV programmes much like us without lay...
How big can an underwater animal really get before physics get in the way? (I'm sure feeding would likely get in the way first, but ignore that!). The Blue Whale is currently the largest animal...
I have a post-apocalyptic world where some intelligent animals become the new major world-controlling species. In particular, some new/evolved species of Cuttlefish and Octopi are beginning to fill...
Sperm whales can go 90 minutes at a time without needing to surface. I am interested in an idea for a creature that is air-breathing, but spends a lot of time at depths of (100m to 300m) and some...
James MacGuffin, famous archaeologist goes on one of many expeditions to Egypt. He crosses the Dead Sea from Jordan, and about halfway through, he is amazed at what he finds. A small group of large...
I want to have planet with as deep an ocean as plausibly possible. How deep can I go given these restrictions? Planet must be in habitable zone of a star Generally, planet should support life Siz...
I've built a device. It can change matter to energy and energy to matter with 100% efficiency. I've built myself a global presence, and populated the ranks of my employees with people such that I c...
In this scenario, corals, sponges and bryozoans have been extinct for 65 million years. In their place as reefbuilders are echinoderms, bivalves, barnacles and worms of the infraclass canalipalpat...
I have made my billions here in the present day, and I'd like to have a permanent underwater settlement. It is about as useless as the Mars One mission (yes, I went there), but some people may c...
I have some ideas, but I'd like my fictional Roman (100BC) General Mikey (ha) to build a submarine(s). This should be able to navigate in lakes and calm shores of the Mediterranean, succeed in bri...
Considering that the oceans are rising (and that humans don't seem too keen on doing anything about it) and that population is growing exponentially, is it plausible to imagine that in a not too di...
One of the first steps in technological is the ability of a civilisation to forge tools* humans achieved this by using fire and creating forges. There are obviously underwater heat sources but I d...
What kind of a scenario would have to occur in order for human beings to seek survival on the sea floor? It could be man made or natural, ice age or heat apocalypse, sudden disaster or gradual coll...
On earth most of our sealife is fishlike (excluding a few other species such as squid/octopus). As far as I'm aware there are no legged creatures which live solely in the sea. In my world I'd like...
