I am working on a planet were life (trees, plants, food, animals, humans) would be bigger/taller than Earth. I have learned that oxygen level or gravity, for example, could help change the size of ...
Scenario A civilization is living on an ancient super structure, they don't know much about it, they just live there and have lived there for as long as they know. For our current situation we can ...
The original, irish lore around banshees has it that they merely foretell the death of someone, but do not cause that death. American pop culture has changed this, so they do bring death and destru...
When torturing people or executing them in slow and painful ways, your victims sometimes fall unconscious, which ruins the point of the exercise. After all, if they aren't feeling the pain, then wh...
As far as I understand for land animals, the max size is as big as an elephant. For water or underwater animals there's no limit, or at least as big as biggest blue whale. So what is the max size...
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...
Black holes are created by the gravitational collapse of massive stars. But in theory, black holes can also be created by any mass at all that is confined within a small enough volume of space, de...
Aquatic races are usually assumed to be stunted in technological development by the inability to create fire or forge metals. But what about doing chemistry at all? The development of chemistry i...
Planets that are larger and have higher gravity tend to have thicker atmospheres, since it is easier to hold onto gases. Higher air pressure leads to a higher air density, and therefore, a greater...
This question inspired by an answer to my previous question My goal is to identify an external device that can be attached to a person to puppet the person's body. A TENS units can cause a muscl...
In this world, women generally live naturally longer lives than men. The typical female lifespan would be 125- 150 years, and a male would be 30-35 years. Our society attributes this to an ancient ...
In my previous post, I asked about how tall trees could grow in my world. To be honest, I really need those trees to be huge for my storie, because a big part of the plot will be linked to those bi...
For a spacecraft cruising without thrust it is my understanding that the sort of spin gravity utilized in the film 2001, for instance, would actually be debilitating to the crew due to the coriolis...
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. Gyvar...
I'm building a world that has a feature that is meant to separate the world in half so civilizations on each half won't contact one another. The feature is magical in origin, but does not seem magi...
So I have noticed that most herbs come from the Mediterranean as confirmed by this site and those that do not often come from either actual Mediterranean climates or somewhat arid ones. So my ques...
In an alternate Earth, there are no bats. Instead, there are "flying monkeys" (which are actually lemuriform primates, rather like bushbabies or lorises.) And even though they have batlike ears, ...
I am writing a sci fi novel in which one of the primary factions is a lost space colony sent to Proxima Centauri (Alpha Centauri C) roughly 350 years prior on a generation ship. The trip took rough...
Would it be possible to have a planet created by a God - but still obeying the known laws of physics - to have a bouncy surface that would be strong enough to bounce any large incoming matter, like...
I'm thinking about making a dark (and I mean darker than Grimm dark) short adaptation of Cinderella. The gist of it is that, after a life of manual labor and emotional and verbal abuse at the hand...
Consider a magic system that follows the Eragon model; "doing it by magic takes just as much (biological) energy as doing it the mundane way". In Eragon, magical energy can be drawn from other liv...
In my story, I need a spaceplane, that is, a shuttle which can fly in an atmosphere as well as in space. It needs to be able to land from space, and then take off and go to space without refuelling...
I will be using solar antimatter production via Schwinger pair production like the VARIES project but I need to store it for bulk use. The containment will be a satellite orbiting the sun close eno...
I did the orbital period for a planet orbiting a mass = 1 sol with a 24-hour year, it's got a semi-major axis of 1.82 million miles - far and away beyond the Roche limit, still beyond the corona, b...
In the 1960s we were disappointed to find that the moon is a pile of dust and rubble with no easily accessible valuable materials. Well, we kind of knew it before that, but we weren't sure. Anyway,...
