Is it possible, given a strong enough magnet, to rip out iron based molecules out of the blood stream/body of a person/animal? Would such an event be the thing that kills someone or are there other...
This is a small arrow shaped creature that can fly without wings. Can it use electromagnetism to fly? Or maybe something to do with ions? Or however ufos are theorized to work? I'm not quite sure...
I'm thinking about a design like this generation ship, which obviously has spin gravity. Would the fact that the ship is rotating affect the use of a magnetic sail? The magnetic sail as a sort of...
Imagine an Earth sized planet consists of only ferrous metals, the creatures living on the planet move around like a maglev train basically they interact with the world and among each other electro...
Imagine a race of humanoid alien living somewhere in the universe evolves weird sensory organ which can only picks up frequency of light ranging from 800MHz up to 2.5GHz which is in the microwave s...
I searched the site and found answers saying hard light can't exist. Apparently in the three years since the last question was asked, scientists started making inroads on making solid light a reali...
For the purposes of this question, let's use the definition of nanotechnology from the tag wiki excerpt: "technology that works with sizes of less than 100 nanometres". An EMP can vary in frequenc...
(As of 2020, February, the 19th, 12:23, I have decided to use a different method than the one originally proposed. The method itself answers the question) Imagine a spell an effect of utterdarknes...
The robot in question is a large, worm-like mining robot built for digging tunnels. It has electromagnets positioned throughout the segments of its body, for the purpose of pulling metals out of th...
Energy released in an exothermic reaction depends on bond energies of reactants and products. Since molecular bonds are electric in nature, at the first glance, increasing Coulomb's force should in...
Stars are never green. When a star's spectra "peaks" in the green range, it also releases a significant number of waves of the adjacent colors - so "green" stars appear yellow or white. I want ...
Someone invents a machine that creates electrons. It takes in some electrically neutral matter, and produces electrons of equal mass.1 Let's consider two quantities of negative charge: $q$ is the...
Wikipedia states: "Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) across an electrical conductor in a changing magnetic field." This one ...
I'm conceiving of a world where humans can readily terraform worlds that were once considered "dead" due to the planet's magnetic field being long gone. In such a situation, what could humans do t...
I have a world where there are two types of beings. One type, let's call them X, exist in our "dimension," and the other, let's call them Y, exist in another "phase" or dimension. Only 10% of X b...
An event has occurred several thousand kilometers from the surface of the Earth. Let's assume some sort of tear in the universe has appeared, from which extra-dimensional or exotic energy is pourin...
Writing about suspended cities within a planet's atmosphere! The story itself focuses on the air forces that fight for each of the hundreds of floating city states living in the sky, but that's her...
A follow-up to my previous question-barrage: Properties of magnetically confined plasma shielding After some of the feedback, I'm splitting it into several smaller questions. In the world I'm b...
There are several ways to directly convert acoustic/mechanic signals into optic signals (e.g. opening/closing a shutter, or the acousto-optic effect). Is there any way to do the reverse, without us...
On a planet, a species uses magnets (i.e. float in the air) instead of wheels for transportation. Roads are easy enough, just slap some magnets in it, at it works. But I was wondering about the f...
James Cameron's Avatar featured floating mountains which stayed aloft due to the Meissner effect; they contained large quantities of the room-temperature superconductor unobtainium, which, due to t...
With specific attention to national electricity power grids. Some pertinent details needed to answer the question might be. What parts of the power grid get damaged by such an event How do they...
If a nascent colony world can be wiped out by a geomagnetic storm on a scale similar to the Carrington Event, what could the colonists build either in space or on planet to protect their electronic...
Suppose I take a group of alligators select the ones that emit the highest frequency of radiation (since all living creatures emit thermal radiation), and I breed those, and get rid of the rest and...
I'm not sure if it's even feasible, but I have a server farm in my book, of a size that puts it on par with Google's. I want to wipe out all the data stored on the hard drives, without destroying ...
In my universe technology is advanced enough to have non-jet and non-rocket booster technology. For a disc shaped UFO all of the technology is crammed in the ship and there was no more room left ...
Inspired by: How much electromagnetic transmission noise does Earth have to emit to be noticeable? Premise: Assume that the infamous Wolf 359 star system has one habitable planet and a second, hab...
Assuming the moon is the same size as ours and its core is generating a magnetic field, and the copper deposits are quite large, consisting of a tectonic plate containing huge deposits of native co...
Lengthy Explanation of Why I'm Here: TLDR; "force field" made of electromagnetic radiation. Recently, I've decided to compile a list of possible technologies available in the 22nd and 23rd centur...
My story takes place on an Earth-like, inhabited world that is far larger than Earth, has roughly 110% of Earth's gravity, and has unusually high (and generally unexplained) EM emissions permeating...
Inspired by a brief comment converstaion found here. I would like to investigate the design and development of an alien species whose technological development did not include an understanding of ...
An advanced civilization collects enough Magnesium and Oxygen, from all over the Galaxy, to equal the mass of a star, and then reacts the Magnesium and Oxygen to produce Magnesium Oxide. The civil...
A civilization creates a supermassive black hole with an electric charge such that the radius of its inner horizon is 3/4 the radius of its outer horizon. In nature, a black hole with this much el...
Part of a series I'm starting since the recent What could make a star green? did quite well and others could use the information here in their worlds. There aren't any "violet" stars. When a ...
If some kind of insane wizard began a ritual that would turn the inner core of the earth into gold, what would happen? Over the course of 15 days, the entirety of the core will become gold. Each ...
In my story, I have two huge generation ships racing each other to another star system. Assume they are on an exactly parallel path, neck-and-neck, about one astronomical unit apart. They are trave...
I've been thinking of ways that an FTL-capable galaxy would prevent weaponized FTL missiles. Ignoring causality violations and paradoxes, I'm looking for a way to keep something based on an Alcubi...
Would it be possible to create a constant EM field that disrupts electronics within it in a similar manner to the way an EMP from a nuclear blast does? Or would it be possible to have a planet wh...
I've been mulling whether the local gaseous makeup of air is changed by electricity running along a wire. My previous question is on hold, and this one is different anyway. I couldn't find exactl...
See, I'm a low-g cargo shipper by trade. We get all sorts of containers in all kinds of shapes that we need to fasten to the deck plating, and to do that we use magnetic clamps. Now, these clamps ...
QUESTION So recently I was doing research on Magnetic Coil based weaponry in the Halo universe, and while reading about how the "Super Mac" worked, I noticed that the theoretical speeds at which t...
I'm looking to build a scientifically plausible mining laser for my science fiction setting. The first approach that came to mind was a high-power laser that heats the surface asteroid until it bec...
I recently came across this paper detailing a plan to use 12 superconducting rings around earth to strengthen our magnetic field. I'm planning on using this same idea for my own worldbuilding. An ...
Within the next decade or two, Earth is attacked by an alien fleet. The various militaries have some forewarning and are able to destroy the attackers by launching most of their nuclear arsenal at ...
Setting: In a fantasy setting much like World of Warcraft (where huge liberties are taken regarding the level of technological sophistication), an evil emperor rules from a castle in which there ar...
Perpetual motion doesn't exist... or does it? In space planets continuously spin around stars for trillions of years due to inertia and gravity balancing each other out. What if a race of brilliant...
How do force field work in many sci fi fictional universes? I remembered the last time I checked the strength of the electromagnetic field a.k.a force field is proportional to the power output from...
Let's talk about the visible light "rainbow" In almost all depictions of the electromagnetic spectrum, visible light is shown as a rainbow, and adjacent parts of the spectrum are monotone in color...
After the WorldBuilding community helped Average Joe start his own microstate, Joe has become scientifically inclined, and uses his money to conduct somewhat dangerous research projects from...
I was thinking of a hypothetical universe in which electromagnetic waves decrease in intensity with the distance instead of the square of the distance. What kinds of effects would that have on that...
