Humans got a one time ticket to the other side of the galaxy, traveling $2r$ in just a few days (where $r$ is the distance from earth to the super massive black hole: 28,000 lightyears) The stars ...
The Premise Setting a near-ish future world, where people live a full life and then upload their minds into different hardware and continue on. Setting a timeline for this, when (what year) are w...
Lets suppose we have a material that is not equal affected by gravity as everything else,I don't care how, anything from dark matter to fairy dust works, but the point is that the weight formula fo...
One of my more brilliant characters is taking a terraforming class and at one point, early in the story, she has to leave the action to take an exam. The question presented in that scene is listed...
You're the head engineer for an advanced civilization. Humanity has long since spanned the stars, as as vast as her civilization has become her need for power has increased exponentially. To feed t...
There seem to be honest scientific exploration in the field of the alcubierre warp drive if you believe some articles on the net. So to be a little bit scientific accurate in a story using it, I wo...
I'm trying to design a species that is largely aquatic and yet capable of walking / running (loosely) on land. I've already figured out a gill and lung type respiratory system to allow them to brea...
Could a planet with an atmosphere composed mostly of neon, with oxygen and carbon dioxide making most of the rest, support life as we know it (specifically on a low gravity planet)? If so, what imp...
This is about "giants" inhabiting a fictional earth-like planet somewhere in the Universe (like those in the movie Prometheus, for example). Assuming that all the conditions (temperature, gravity,...
Could neon or argon glow naturally in any way? What would be needed in the atmosphere? P.S. Please don't change my question?
Slime molds are a fairly well-known grouping of organisms, performing a valuable function as real-life detritivores and bacterivores, as well as inspiring fantasy tropes such as oozes. Many slime ...
I need an Earth where the atmosphere has become unbreathable for humans and animals because all plants have died. But everything else should stay pretty much the same. So here are my questions: ...
In my world, instead of mammals, birds have become the dominant order. Similar to how Quadrabirds replaced the grazing mammals; Aquabirds will take up the niche cetaceans occupy. My goal is that t...
I'm wondering what natural phenomenon would allow a planet to have a part of its surface always under daylight, a part of its surface never seeing said light, and a third part where day and night c...
Let's say you're an alien and you want to make sure your species outlives your planet or whatever disaster you currently face, whether it be natural or engineered. You load up a bunch of self-repli...
We've seen questions about multiple planets in a single orbit before, using Lagrangian points, through orbiting each other as they go around, etc. I'm looking at the creation of a hypothetical syst...
Terrorists gain complete control of the world's nuclear weapons and they want to destroy the moon. Could they do this with ICBMs? If not, is there enough power in the arsenal to destroy the moon if...
I was wondering if three planets can rotate around each other so that: Two of the planets are smaller and rotate around each other Both of the smaller planets rotate around another, bigger plan...
This is assuming that the direction of the gravitational gradient remains the same ("down") - it's just the magnitude that's varying. I don't need an accurate figure, just a ballpark one, which is...
I am writing a story set in a fantasy world, with an atmosphere similar to Earth's. Would it be possibly to have a forest situated near wetlands which create radiation fog at night, which drifts in...
Finally, I have done it. I have bought a large and beautiful four bladed windmill. A smock mill to be precise, really high and all functional. There is the whole ancient machinery in it, completely...
The Spriggan is a tree-like creature native to the Elder Scrolls, where they are often found in forests and groves. In appearance, a Spriggan appears to be made of entirely wood and a glowing sou...
A mad scientist finally creates a strong AI, but this AI is a complete Narcissist (due to a strange glitch in its programming). It believes that it is a god and wants humanity to worship it. But ho...
Could humanoids similar to the cubic-based beings found in Minecraft be physically plausible? The requirements are not that human can take such a shape, but rather that a being of such size and sha...
Is it possible for traffic lights to work underwater? Even for a short period of time. I understand that any electronics inside would short-circuit pretty quick. But could it be protected by the ac...
