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...
I want to put a circular city in geostationary orbit. The city will have a radius of 20Km. I was thinking of using quantum trapping/levitation to achieve this. Here's what quantum trapping is: ...
In a previous question on this site I asked about the side effects of a having ludicrously strong, permanent, static magnetic field on the surface of a planet, capable of pulling in non-magnetized ...
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 ...
Can two objects solar powered, equal in weight, traveling on the same orbital path in the opposite directions propel each other to intersect on the opposite side of the Earth in alignment to propel...
I asked a similar question earlier: What would happen if electricity stopped working?. But I was also thinking about what would happen if magnets stopped working. This question is very related to w...
The Volt Dragon is an incredibly dangerous beast that reeks havoc on any attempted air travel. This dragon generates many small but powerful magnetic fields whose strength can be varied voluntarily...
This is a bit hard for me to put into to words, but it is an idea I have been working on for a few days, with input from a few other people. I have actually brought up part of this in a previous qu...
I am trying to create a planet with low gravity that keeps an atmosphere and has an ocean that covers the whole planet. Basically I am developing beings (separately from this question) who can live...
I've been playing with ways to make my world interesting, and also further justify the limited use of ferrous metals. One idea I had was that my world might undergo regular and intense geomagnetic ...
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 ...
Inspired by this question from yesterday. Solar flares can give off a large amount of radiation, but on Earth this is typically absorbed before it reaches anywhere but the poles, and even then on...
Is there a way to induce a solar flare / coronal mass ejection (CME)? For instance, could a very tight glob of charged particles reconfigure the the Sun's corona leading to this type of event? Is ...
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...
Let us assume that my new world has within its rings, shells, and blobs of remarkably cool magnetically-involved stuff such that its magnetic field is toroidal (shaped like a donut) rather than sph...
Would a starship that was propelled by magnetic monopoles fly faster and longer than ion engines (assuming magnetic monopoles exist) of course.
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...
The purpose of a magnetic field is to shield against solar winds, which are relativistic ions produced by our Sun. This is a typical O'Neill cylinder with 4 islands. I'm looking for a cost effectiv...
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...
So I have a story about humans far off in the future on a different planet that have evolved to be more in tune with electromagnetism and magnetism. Their technology mostly works because of magneti...
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'm trying to find some type of space weather or other natural occurrences that would result in the intensity of Earth's magnetic field dropping for a few hours to maybe a week or two at most. Pola...
Could a species, over centuries of evolution, evolve a special organ that stores pure energy and allows it to control its own magnetic field? What possible steps would have to happen for this to oc...
I'm curious as to what the implications to any navigation system are: ship trekking aviation etc. Will their compass change shape (as being spherical), or might they dump the compass alltogeth...
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 ...
Our Earth and Venus each keep a thick atmosphere because of a magnetosphere. Most terraforming scenarios of Mars involve transferring water and other gases from the ground to the atmosphere. We no...
Say that you have a cuboid "planet" that can retain its shape. Can it have a cubical iron core (as opposed to the spherical one described in this question) and generate a magnetic field? Would the ...
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...
In the story I'm writing, a gas dwarf (named Eden) is discovered in a triple star system. Its atmosphere is mainly oxygen and water based, and its gravity is slightly higher than Earth's. Unlike o...
Suppose human being evolved a special type of sensory organ that can detect Earth's magnetic field, beside discarding compass when hiking what else can we benefit from this extrasensory gift in the...
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...
Would it be possible to somehow inject astronauts cells with safe amounts of magnetic metals, or use some sort of magnetic properties, to hold them down to a space station floor with magnets?
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...
Assuming it was possible to create an artificial magnetic shield on the moon, would it be possible that a sufficiently powerful field could hold onto an atmosphere despite the low gravity. Thanks
So having read a couple of other questions on here, and postulating over this for a while, here's my question. Is it possible to have two magnetars in a distant binary orbit, with an earthlike pla...
The binary stars system is comprises of a red giant with 6 solar masses and a Sun-like star, the exoplanet is orbiting in the Goldilock's zone with a molten iron core which generate a magnetic fiel...
Is it possible for a planet and moon to generate electricity in some way? Could a combination of magnetic fields and iron content in the crust or core produce electromagnetic induction due to the r...
Imagine a world with a very wacky magnetic field, the magnetic poles are not aligned at the top of the axial tilt and the sun is active enough to cause huge northern lights each night. I know elec...
It's typically regarded that life needs liquids of some kind to evolve. But liquid is just a state where molecules can move around freely in order to interact with other molecules instead of being...
This theory, what I call the world shift theory, states that the Earth's original orbit was solar stationary at one of its poles constantly facing the Sun, building, over time, the magnetic poles. ...
Specifically, I was wondering if a core of magnitite or some such other magnetic metal could be a planet's core. This is in relation to my other question, found here: Can airborne floating/flying...
