Question A realistic reason for gods to be incapable of meddling with mortal affairs?
So, gods. What are they. Gods are a race of various creatures that share a two important characteristics: They're connected to The Source. They can successfully produce offspring (though without god powers) with any animal (including humans and dragons) how that happens isn't clear, but it has some...

Question How to prevent this micromachine swarm from doing anything besides what it was intended to?
So, there is this entity in my story, Slenderman, who's ultimate technique is the Blackout. Blackout causes electronic devices and light-based communication to fail within a 5 km radius of a chosen point. In layman terms, it makes everything foggy (that fog are the machines themselves), pitch black ...

Question So, magic is based on swarm robotics and nanotechnology. How can I have Anti-magic fields?
So, at its core, magic is using a swarm of tiny (50-100 micrometers), naturally occuring robots to deliver substances to a given location and initiate chemical reactions that lead towards the desired result. It involves physics, chemistry, programing and communication. So, how to prevent sieges from...

Question The best realistic spell to brick firearms
Okay, so, how does magic work? Magic, at the end of the day, is a swarm of tiny machines (hardly visible to the naked eye, but still within the 10-100 micrometer range) that carry out a task. Individual machines have tiny manipulators with a "hand" that they can use to lock together and share info a...

Question How low can the density of a living creature be?
In the anime, called Attack on Titan, the primary antagonists are these huge, humanoid creatures, called titans. Titans have sizes between 15 and 4 meters. Larger titans aren't unknown, but they splatter, more precisely, they nuke when hitting the ground. The reason why smaller titans don't nuke th...

Question Nanomachines and deception are the essence of magic, how can I explain meteor showers and similar large-scale weather spells?
So, dragons have access to this thing, called word magic. Word-magic spells are typically need way more energy and processing power than regular magic, they also have nasty cool-down times. A dragon has so-called spell slots, larger spells take up more slots and need more time to have prepared again,...

Question How could a human-shaped fluid creature move like an actual human?
So, there are creatures with insane regenerative abilities, like casually putting their severed head back on their neck and it's fixed in mere seconds. The reason for that is that it's not true regeneration. These creatures are made of a fluid, so if any part falls of or gets damaged, it can quickly...

Question Futrinka street and the plausiblity of comfortably habitable giant-pumpkin houses
So, there was this pupet show about two characters, Mazsola and Tádé. They lived in a BIG pumpkin, that had been hollowed out and repurposed as a house. It looked something like this. Now, I kinda like the idea of a big pumpkin house, especially if one was to carve the windows so the lights woul...

Question "Where are you going dragon, don't you dare leave your rider behind!" How can a rider keep up with their dragon?
So, let's suppose I finally made it. A creature that's very agile, able to resist most small-arms fire and has a whale-oil breath weapon. Flight is solved with bones, as strong as carbon fiber, (laughs in limpet teeth) and even more muscle on the pecs. This example dragon's name will be.. Gyvaris. ...

Question Aftermath of the "Were plague": Dealing with "Strays"
One morning, as Gregor Samsa was waking up from anxious dreams, he discovered that in bed he had been changed into Legosi from Beastars. He felt a dull pain a bit above his behind, as he lifted his head up a little, he saw the rest of his body was covered in short, light-grey fur, his feet, s...

Question How could wyverns fight effectively if they can't carry stuff around?
So, two nations are in a war, land is off-topic as it's filled with zombies and necromancer zombies. The other logical option is the sea. Now, one nation has these creatures, called wyverns. Wyverns are quadrupedal creatures, capable of flight. They retained five digits on both their forelimbs, wit...

Question Is there any plausible in-between of Endotherms and Ectotherms?
Someone in the comment section of my previous question pointed out the energetic problem of ectotherms with human intelligence (the brain needs a lot of energy). I still want to keep my lizardfolk restricted to warmer climates, as all the other suggestions just didn't work (lizardfolk don't have bl...

Question What to remove to make a realistic Omni-Directional Maneuver (ODM) gear?
One thing I like about Attack on Titan are those lovely Omni-Directional Maneuver (ODM) gears! They're the perfect combination of a jetpack and a grappling hook. I love how the thrusters are placed at the center of mass (the hips), I love how it requires a full-body harness to distribute the force, I...

Question Realistic "Titan hardening" for living creatures: what's the hardest substance a biological process can produce?
SPOILERS FOR ATTACK ON TITAN, READ AT YOUR OWN RISK... Hardening, or Titan hardening is an ability posessed by certain types of titans in the anime Attack on Titan. Since the setting has rifles and cannons, hardening comes in handy to protect against them. Now, I'm not trying to imitate the ridic...

Question Would roleplaying as wacky Nazis help my deities maintain their mental health while they're stuck in a bunker?
So, once there was a war between the titans and the gods. In the end, the gods' leader, Anon, found a way to permanently remove the titans from the world, but the victory extracted a terrible price. Titans and gods were fundamentally the same creatures, and the source of their power was also the sam...

Question What's the deciding factor in what my Foresight can predict?
When you have foresight, it's guaranteed that confusion will be your epitaph (thumbs up to the one person who gets the joke). Basically, it only grants you advantage on actions, so you still can't automatically succeed in, say, rolling a d20 (not on the table, in the game), aka: you can't immediately...

Question Is it possible for psychological trauma to cause a lasting coma?

Question How could an illusion effect covering all senses scare someone to death?
The "Weird" spell in my world is basically a magical version of the US government's goals with the "MK Ultra" project from the 1950s: it induces a shared hallucination in every creature within a 9.1m radius of the spell's ground zero. It manifests the victims' worst fears (and possibly combines them...

Question Can you replace goethite with something else in limpet teeth to decrease its density and maintain its strength?
The limpet teeth's microscopic structure is analogous to man-made short-fiber composites. Its strength depends on the direction of the force, relative to the orientation of the fibers. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3350734/ For worldbuilders, this thing is a gift from Glarnak (our aw...

Question The best role for a dragon in protecting a settlement?
One of the plotlines, I'm currently working on, is about a dragon who is forced to serve a settlement to "pay" for some of his past "crimes". For clarity's sake, we call the dragon Gyvaris. Gyvaris is a roughly horse-sized, hexapodal creature with both reptilian and avian features. Intelligence is ...

Question My mysterious "ruins" wander around and change on their own, what'd be a rational way for them to do that?
Civilization is fairly young in my setting. Thus, the sheer number of ruined buildings and abandoned structures, found throughout the wilderness, seems strange. The ruins vary a lot: has-seen-better-days forts, modern suburb houses, post-communist concrete slabs and lonely staircases (in-universe ca...

Naturally, he outsourced it to us. The device has to play the song in high-quality and loud-enough to drown out gunshots a...

Question Why would the Ressurectinator cause phantom pain in the people it brings back?
The Ressurectinator is a handy machine than can bring back people from death. Unlike the virgin Lord of Light, the chad Ressurectinator does that without human sacrifice and/or permanent scars. You only need the person's brainscan. Everyone has one, it's constantly updated and nothing can destroy it...

Question What would make a bigger animal be able to fight effectively against humans with firearms
Basically, I have a creature that is larger than an average human, and smaller than a bigger shire horse. So, size is adjustable. The bodyplan is similar to that of a horse, except for a longer neck and a powerful tail for ranged attacks. This animal was supposed to be fighting humans armed with var...

Question How could a scientifically plausible Rust Monster quickly erode iron-based metal objects?

Question Anatomically Correct City-leveling monster
In many fantasy stories, dragons are portrayed as giantic monsters that can destroy cities, if not, then at least a castle. Now, we can theoretically create something flight-capable even with masses of 250-500 kg if we're willing to abandon evolution. We can also make that creature powerful enough t...

Question Dragons have an armor that is similar to that of sungazer lizards. Why would the dragons have the spikes as well?
A Smaug giganteus. If you do as much as think about slaying it, I'll force feed you gasoline and shove a match down your throat. Sungazers are awesome. They're so awesome I decided to base some parts of my dragons' appearance on them. Dragons in my setting are hexapodal, roughly horse-sized, omniv...

Question Is a 500 kg flying creature possible?

Question Would stronger tendons and bones allow for stronger muscles for the same weight?
Follow-up to this question: Would linear increase of a muscle's dimension increase the power as well?

Question Would linear increase of a muscle's dimension increase the power as well?
The square-cube law applies to bodies with the same shape, and require them to be increased/decreased in all three dimensions. If you were to take a cube, with every edge being a long, and expand it to be 3a in length on the y axis, it would be three times the weight and area. And with that, you just...

Question The Requiem quietly plays: Is it possible for molecular machines to read and modify proteins in the brain?
So, I had a concept (a bit large for a single question). One of it's parts is nanomachines rewiring the brain of the subject.

Question Justification for predominantly late-medieval style buildings in a modern world

Of the six limbs of classic dragons, the forelegs always stuck out like a sore thumb. They're dead weight in flight, etc...
