I am an average person being hunted down by a homicidal cyborg. He is about 90% metal, with his only remaining organ being a brain and all other meat on him being tissues which serve only as an anc...
In my other question I tried to find out if it makes any sense to colonize other planets or moons instead of just building space stations. The answer I accepted seems very well elaborated to me and...
Let's say Earth's nations meet up and decide to start to colonize space in the next ~50 years. What would the first resources/materials be, that we gather in space/from other planets that we need t...
I'm creating a human race that has 3 sexes: male, female & hermaphrodite. Is there any biological rules that limits what should be the ratio between sexes or I could just pick whatever works b...
This is sort of on the more realistic side of worldbuilding, but maybe somewhat exaggerated for the sake of a setting. What's the fastest atmospheric pressure drop in weather records? This questi...
The basic idea is that a building (house, business, etc...) would be on a type of foundation that would allow it to be lifted into the air (not by a lot, I'm thinking inches at most) to store energ...
I am starting a theorycrafting thread in a video game forum. It deals with the creation of a Hegemony created by the descendants of a colony ship that was cut off from returning to Earth (wormhole ...
This is the link of what I have in mind, https://www.youtube.com/watch?v=jKvnn1r-9Iw , can a planet rotate chaotically through this system and still be habitable? If it's going to collapse after a ...
In the climactic final battle Faction A engages Faction B on Faction B's planetary base, both in orbital and ground combat. Realizing they can't win, Faction A activates a device that transports an...
Mars gets somewhat nice In about 1.6 billion years, the sun's habitable zone will have moved outward, increasing the carbon dioxide in Mars's atmosphere. According to Wikipedia, its surface temper...
So, you have eight planets in the solar system. Mars, Saturn, etc etc. **What would happen to poor old Earth if, for some yet unknown law, some handwavium, or that statement, the aliens did it, if ...
Radiating heat into a vacuum is a no-go, so a spaceship that generates any kind of heat is going to be in trouble. I had an idea for a potential solution - dumping your heat into a disposable heat ...
Is there any way to explain how did humans in my planet end up with extreme dimorphism without resorting to polygyny nor "magic"? I want men to be around 6ft (183cm) - 230 lb (105kg), while women ...
So I'm creating a character that is an extradimensional being that exists outside of time. If we experience time as a linear event, how would time be perceived if this being has the ability to see ...
Okay, so my character is relatively short (5'6 feet). Her bones are hollow,but similiar to a birds-very dense to make up for strength. Her wingspan is 16 feet. I want her to stay as humanoid as pos...
Slimes are a common monster we often see in games such as Minecraft, Terraria and Slime Rancher, but it is never explained how such an animal can exist. How could the body of such an animal even ex...
I'm currently working on a Sci-Fi story. Many of the super-materials in my story are composed of "Neo-Matter". List of Neo-Matter particles: Up-Neotron, Down-Neotron Neo Matter is essentially lik...
Let's use Mercury as an example, we can pretend it orbits in the habitable zone of the Sun, would Mercury's magnetic field be able to protect an Earth like atmosphere? And would the lower gravity m...
To be very-very simple: The very main setting of my world is a very special and very small galaxy, the galactic core of which is a quasar - with the "iconic" light beam in the middle, serving a sp...
Tau Ceti e is possibly a good candidate for colonisation as it has a yellow dwarf sun like earth. But it's mass is estimated as >4.30 ± 2.1 of earth. (See Wiki) I remember from a documentary th...
Imagine we have a shade launched in space that can be turned opaque and transparent. We can use it to communicate in binary, and mathematically sound extraterrestrials can pick up the pattern. Of c...
I've worked a couple of Habitat for Humanity mass builds where entire houses go from a poured foundation to complete in the course of a few days, and whole neighborhoods are built in a week. There'...
Humans are derived from arboreal shrew-like animals that survived the cataclysm which wiped out the larger dinosaurs. As far as I am aware this series of events is entirely the result of chance. Wo...
In the mobile game "The Path To Luma", the main hero travels to very tiny planets. Let's not think about where is the sun and how we leap through such small planets. What I want to ask is, if there...
I'm creating a world with different oxygen density, about 15%. When given same fuel and air pressure, how will the fire burn up in this 15% oxygen density atmosphere compared to our world? And the ...
