When I say multicellular I mean it's made of more that one viruses. Basically it's a bunch of viruses that act like viruses but use the viruses made by infected cells to build a "multicellular" lif...
Suppose we walled off a 1000 km square. These walls would be made of unobtanium (so they don't break), and have no cracks or holes that go all the way through. They are also around 15 kilometres hi...
Early life, and many modern organisms have what we call 'blind guts'. Food enters and exits via the same opening. However, that is inefficient and has been widely replaced with 'through guts'. Fo...
I have a mountain in a story that basically needs to be taken down (inadvertently) by human action in a world with premodern (so mediëval/ early renaissance at best) tech levels. I have been thin...
This is sort of a follow up on my question Could a "multicellular" virus exist? in which part of the consensus was that viruses simply can't hold enough DNA. In theory, could DNA form in a structur...
We know that in biology, a species evolves to better survive its planet and its various climates and geography, which is mainly a result of natural selection. But, sometimes, this natural selecti...
I am wondering if habitable planets could form around stars in super dense dwarf galaxies. There are some super dense galaxies such as M60-UCD1 and M85-HCC1 which can have a typical distance betwee...
This is a submission for the Anatomically Correct Series Giant seahorses are often portrayed in fiction as being ridden by merfolk or other underwater people. I'm wondering if such a creature ...
So in the world I'm building, I'm considering to give one of my characters the ability to quantum entangle specific particles on demand. Now although for many years we thought quantum entanglement ...
Those of you who are familiar with the DC Comics hero Firestorm know that he can alter the chemical structure of any form of inorganic matter, provided he knows the chemical equation. In my story, ...
Hideaki Sena's cult classic novel, Parasite Evil and it's video game sequels revolve around the premise of mitochondria gaining sentience and usurping mankind after aeons upon aeons of multicellula...
Premise/question Correct me if I'm wrong, or if humans have terraformed the planet by the time you're reading this, but Mars is mostly desert-like. It has large ice caps which contain most of its ...
In the universe of my story, the Earth is ridden with metahumans with uncanny powers that do all sorts of different things. Of course, to do all this, they would require a tremendous amount of ener...
Many know that the Lantern Corps of DC Comics are capable of constructing objects of any shape or size out of hard light using their power ring fueled by their emotions. However, I'm wondering what...
The setting I've cooked up for a D&D campaign I'm running features a fair amount of buildings that have been totally abandoned by civilization for hundreds or even a thousand years. Obviously w...
The characters in my world use oxygen spheres like the top answer to this post (a leather balloon filled with air) to safely traverse land filled with smoke. How would you know when you are runnin...
I am currently working on a character backstory for somebody whose fictional character gets sent back in time an era before his species existed (essentially to bronze-age times or even earlier, it'...
I am working on a world where an event, like a celebration, occurs during every lunar eclipse. I would like to have lunar eclipses occurring more frequently--maybe even once a month--in order for...
in most science-fiction stories that include alien races, said aliens have a roughly humanoid appearance (being an erect bipeds). now while it's likely that the vast majority of sapient life (being...
In many fantasy works, the world typically has giant caverns that house entire civilizations and ecosystems that are (mostly) disconnected from the world above. However, this concept, at least in ...
In my story, there is a planet. The planet's name is not really important for the sake of this question, so we're going to refer to it as "dead planet". Background: Dead planet is entirely hot d...
Let's say you have a planet about the size of Earth. It has three moons, each roughly the mass of one-third of the Earth's moon. Would this cause tides of different magnitude than those on Earth? A...
In this world, people have the legal right to fight anyone to the death, for any reason, as long as the fights are done before an official whose sole job is to regulate these duels. The officials i...
So, as I understand it, the spacecraft would need to move in the opposite direction to the orbit. Are there any calculations I could make to attach a clicking-tock onto this? If the spacecraft were...
The moon is similar to earth but orbits around a gas giant, the sun has ended its life cycle and so the only energy received on the moon comes from tidal interactions heating its core. On earth an...
Basically, the title. Trying to figure out how reasonable stealth in space would function, and while I have mitigated it, I am looking for methods to improve it. But mainly, is creating a sort of h...
We may all have some familiarity with winged skulls - from Avenged Sevenfold's album covers to bikie shirts. However, for my science-fiction/horror story, I am curious about how these creatures wou...
Working on a medieval setting I thought of the idea of a biome similar to Minecraft Ice Spike Plains where this ice structures naturally occur. These structures in particular are tall and sharp tow...
Would it be feasible to have an interstellar vessel be constructed in flight after smaller sections are boosted up to speed? The idea here is about using laser sails which would be easier to use wi...
First question on stack exchange I've been lurking and learning for years and finally decided to pose a question for a novel I'm working on. Given the appropriate advances in material sciences an...
In some birds especially owls, we can observe a structure called facial disk, which is mainly composed of feathers and helps to direct sound to their ears. While being more common in owls, adding u...
as the title, my question is how big a pelican like creature with its pouch mouth need to be in order to carry grown up human and still fly. since as far as i know hollow bone is to fragile for hu...
This is a post-apocalyptic setting I'm working on. The world has been overrun by invisible monsters from another parallel universe. They can be heard and smelled, and they can form claw prints on t...
The Diclonii are an evolutionary offshoot of modern homo sapiens from the Elfen Lied series. Most Diclonii can get distinguished from humans thanks to small bone and cartilage horns resembling cat ...
I want to create a glutton creature that can open its mouth wider than the prey item like snakes do, but also can bite through that big hard object and even chew it; this creature doesn't swallow p...
Brief setting notes: it's a "basically earth" type situation, a spinning ball of rock in space with the same size and gravity and atmosphere and magnetic fields and everything else. The main diff...
On plain Pilar forest biome of planet X, you have mostly 3 types of vertebrates: those who burrow under the ground those who run through the widely separated trees those who live above ground le...
My temple was built near a kaolin surface mine, which is itself topping an old deep mine (where they used to mine radioactive metals, rare earths and possibly other miscellaneous, if need be). This...
In the large pillar forests of planet x, a group of vertebrates, in order to hunt down the fast climbing creatures that inhabit their habitat, rather than developing speed as well, went on another ...
In my book series, I'm worldbuilding a planet whose culture is based on Celtic mythology and history, and in order to be consistent with real life I feel like the whole planet's environment needs t...
Earth sized planet in the goldilocks zone. Similar mineral composition and surface water. Photosynthetic life evolves and thrives on land and sea. Atmosphere and climate comparable to the beginnin...
My augmented society of humans have managed to engineer their power-hungry cyborg components to run on a hydrogen fusion reactor. Whilst they have so far managed to fuel it by drinking lots of wate...
I, Rey Skywalker, am officially the greatest Jedi in existence. I successfully took down the remnants of the empire single-handedly, defeated my arch-enemy Kylo Ren, and killed Sheev Palpatine, t...
My fungus starts out as an extremely small spore, this small spore will bury and implant itself near the spinal cord and cerebellum, and will then secrete an enzyme that hijacks and later puts it i...
While the intended end state is that this planet can support space-faring lifeforms, the solution under question needs a sanity check. I cannot commit to many numbers with how speculative this all ...
One of the planets I'm thinking of for my book series has all of its landmass in the northernmost half of the northern hemisphere (it is thus mostly a water world) and is completely geologically de...
I'm trying to come up with idea's that have some plausibility of sending information FTL. So we can entangle particles together. When you measure them you influence them. If you measure one up the...
Now octopuses are quite smart already capable of camouflage and puzzle solving. given this I was wondering whether Octopuses could Convergently evolve sapience (human level intelligence) and wha...
In modern day society, few or many people have been fascinated with integrating robotic parts to their bodies. But sometimes that idea is taken to the next step, in which people want to have their ...
The species I have created looks eerily humanlike, practically indistinguishable from human except for a reptile-like tail and an exposed brain. The top portion of the skull is replaced with a gla...
