If $8.8 \times 10^{16} m^3$ of water volume is added to the surface of Venus, how would I calculate how much of Venus would be covered in water? The land of Venus has its topographical features wi...
Three natives who study their version of science on the surface of a large rotating habitat located in a cylindrical shape in the space between our solar system and Alpha Centauri, are trying to fi...
For starters, allow me to define more carefully what I am asking. For now I am not worried about any of the following, as if this question is answered they will be covered in later questions: Bon...
Here is a link to an online animation of stars' movements in a trinary system. Basically, the three stars are orbiting around a barycenter; one (yellow in the animation, mass = 1) closer to it a...
So I want a large power source to heat my new real estate on the Jovian moons. I create a micro black hole (MBH), maybe a few kg, maybe more and drop it into Jupiter. I expect the following to h...
Blood of most vertebrates contains hemoglobin, which contains iron. I've imagined a world where someone once had a seemingly stupid idea of using blood as a source of iron. Now, the world is analo...
My plot is to have temples,castles and cities built on top of the remains of previous structures repeatedly to create a multi-level underground dungeon. My goal is to figure out how many levels thi...
The end goal is to have human like beings with vestigial horns or antlers, but I am unsure of what types of horns they should be. Apparently there are three type of horn: living horn-bony outgr...
Given modern technology, what kind of bandwidth could you expect for communication with an extrasolar spaceship? For example, is HD video possible? Is it safe to assume it would vary by distance? O...
The sun is perfectly fine, but for generations, not a single human has seen sunlight. Earth is completely covered in black fog, reaching high up into the atmosphere, so that not even skyscrapers ca...
Consider an interstellar spaceship. It is a rather classical design, somewhat similar to the ISS Venture Star from Avatar: http://james-camerons-avatar.wikia.com/wiki/Interstellar_Vehicle_Venture...
This is in reference to Could an organism have evolved to kill its prey by shouting at it? However, most answers here speak towards the brute force side of the equation, measure by it's decibel le...
For a while now I've been building a science fiction world and I've been thinking what would be a feasible way to power a large ship capable of interstellar travel. I've always disliked the idea on...
Using my world changing invention and my massive intellect I have created the perfect defensive tool for myself and any minions valued friends I deem might need one. The tool is a super suit that ...
I'm designing a world, and I want it to have major geological changes over a short period of time. This includes continental drift, which I'm assuming should have some interesting results. In parti...
Our universe is described as having three physical dimensions, plus one time dimension, where the eigenvalues for the physical dimensions are all the same, but the eigenvalue for time is opposite (...
I'm currently writing a story, but however I'm having trouble with one part. The hero is faced with a situation where he has to create a fire strong enough melt 5 kg of copper, and he only has a ma...
Nuclear rockets, or as I like to think of them, "half way between a continuous small atomic explosion and reactor whose front fell off". There are many variants, and my aliens are using relative si...
I've read that even in a "perfect" vacuum, matter exists in the form of virtual particles that spontaneously pop into existence only to be immediately annihilated. This suggests to me that it might...
I know the default will be blue, but just HOW blue, i.e., wavelength in nanometers? I have a world with the following stats: Radius: 4628 km. Mass: .35 Earth (2,09076 x 10^24 kg). Atmospheric D...
I've been reading here for a little while, but this is my first question. I am trying to come up with either a concrete set of numbers for a single answer for a binary planet system, or a simple fo...
A star system consisting of two stars forms, with one being more massive. As such, the larger star soon exhausts its fuel and ends up as a neutron star. The secondary star has a semi-major axis of ...
There is a predator that lives in the forest. It is roughly the size of a large bear, and moves quite slowly - a person could outrun it at a light jog. Nor is it agile - although its arms and jaw...
If the holograms are really advanced like the hologram of Snoke in The Force Awakens and they are haptic, which means you can feel them, can they be used to make an immersive virtual reality envior...
I am creating a creature which uses infrasound to immobilize prey and I have done a little bit of research on the effects of Infrasound on animals, finding that 177 dB with a frequency between 0.5 ...
