The idea of a planet where ammonia replaces water as the dominant liquid in the environment is quite popular in science fiction. I tried to develop a scenario where these kind of oceans are plausib...
How many moons would be required to induce almost continual tidal pull to create a near constant tidal riptides?
On Earth, civilization grew up around river valleys. Rivers are useful as a water source, a food source, and a waste disposal system, but their most important function to a civilization is enabling...
Could a species with an incredibly advanced electroreceptive organ (such as that of a shark) be able to use it above water? The gas-mix in which the sense works must be breathable to humans, and it...
Chainsaws in games and films are an epitome of gruesome dismemberment. In Zombie attacks they are used to cut through cloth and flesh while in games they can dismember if not cut from skull to groi...
Rust Monsters are one the few original monsters in D&D that didn't fade into obscurity. Probably because of their ability to turn James' favourite metal items into dust. Rust monsters are ba...
Would an organism that evolved on a world with a short day length have a faster metabolism in comparison to one that evolved on a slower rotating world?
I'm working on a scenario operating on Clarke's Third Law, with nanotechnology percieved as magic to humanity, and I want to create a non-spiritual afterlife for humanity. My intention was to simpl...
I am trying to construct a terrestrial planet that is almost entirely made of silicates but with a core that's able to generate a magnetic field. I really don't want to use iron, nickel, or cobalt,...
Would it even be feasible under science fiction logic? It would allow nuclear weapons to be mass produced if the nuclear pasta could actually be collected and contained safely.
I'm working on a story about Earth or an Earth like planet with current or very near future levels of civilisation and technology drifting or speeding out of the solar system. Currently my method f...
Here is a big one for you engineering fans to chew on. First off, a little context: The giant robot in question is called Mazinger Z, considered to be fiction's first pilotable mecha, launching t...
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 mass...
As you know, mythical animals like the gryphon, dragon, wyvern, roc, etc can carry things as they fly. For a big creature to fly, it either needs to massively increase the spread of their wings or...
In my world, taking place sometime in the near future, scientists decide to mess around with genetic engineering. The goal is to create hybrid supersoldiers with animal genes ad have them perform e...
Is it physically possible for a complex crater to form and remain stable after an impact event large enough to deform the Earth's crust globally, insofar that the surface of the planet becomes unre...
Let's say that around 4-5 million years ago, members of the earliest proto-humans, maybe Australopithecus, get whisked away to another habitable planet/parallel dimension - doesn't matter how at th...
I think it would make sense for hurricanes to be combatted using shade balls to block the evaporation of the ocean into the storm. What would we need to stop a hurricane? Info on shade balls.
These humans must never see the ocean and should still be able to survive. They can only get out of the land if they improve the technology level. Is it even possible? The lakes or seas should prob...
I like the idea of elves having a distinct weakness against iron, to the point where they're intensely scared of it and can't stand the touch of it. My question is: Assuming the Elves are mostly...
Consider the following GIF: The brooms from this Fantasia scene are always busy. They dance around energetically in a military-like march, never stopping to rest. When their wizard overlord is o...
First question so hope I'm doing this right! Working on a setting right now where a bio-engineered virus/plague is wiping out a large portion of humanity. Most died upon first exposure. Some surviv...
Malevolent Spirit: Malevolent spirits are swarms of barely visible machines that have accidentally been imprinted with a deceased person's memories. They posess swarm intelligence and communicate w...
The cold fusion generator is ready, loaded with tons of heavy water. The scientists stand by ready to measure the energy output of the amazing new technology. They turn it on, and as expected, ge...
For a story I have, modern civilisation must be destroyed by a worldwide disaster. The objective is roughly something that: Could be man-made or aided (if not now, maybe in the future) Decimates...
