I was recently introduced to the South Atlantic Anomaly. As I understand, for satellites and space craft, this is a natural feature that can wreck space craft by taking even computers designed fo...
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...
I have some plasma life forms that have evolved within the photosphere of a star and also capable of existing on a neutron star and the ergoshpere or accretion disk of a blackhole. This lifeform c...
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...
Magnetic white dwarfs (MWD) comprise almost 2 % of all white dwarfs and they are characterized by having a strong magnetic field, whose strength varies between 1 T and 100 kT. Compared to the Earth...
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...
Imagine a gas giant as massive as Jupiter has a enormous planetary ring which will expand and contract throughout its orbit around a main sequence star. Then there is a moon as massive as Mars an...
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...
Many stars, including the Sun, periodically display starspots, cooler areas of the surface associated with higher local concentrations of the stellar magnetic field. They can sometimes be a couple ...
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...
For an artificial gravity ring station, could you make a central hub, using similar magnet technology used to levitate magnet trains here on earth, to reduce the amount of mass rotating? My thought...
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 ...
Spacecraft in my Scifi setting use strong magnetic fields for many purposes. Fusion containment, magnetic nozzles, gauss guns, magnetic fields as pusher-plates for nuclear pulsed propulsion and def...
I will be using solar antimatter production via Schwinger pair production like the VARIES project but I need to store it for bulk use. The containment will be a satellite orbiting the sun close eno...
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...
I want to have a two-world binary planet system where both have intelligent life, orbiting a single star. The two planets are assumed to be tidally locked to each other and orbit each other every 3...
On Earth the planet's magnetic poles line up fairly well with the geographic poles. This makes things like navigation very straightforward as all compasses point to (roughly) the north pole. How...
The probe in my mind is unmanned, with a super-reflective surface to deflect most of the energy from the Sun on all wave length, only absorb enough to power its operation. Please also elaborate i...
I have a planet similar to Venus(similar size and atmosphere) that has floating continents in the atmosphere due to strong magnetic fields. If it is possible, what would the continents need to be m...
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...
Let's say I have a terrestrial planet superficially like earth, except that it rotates much slower (about 10-15 days per rotation) and its atmosphere is ideally several times thicker. If I want thi...
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...
If there were an absolutely terrible accident, and part of Earth's core was displaced toward the surface, making a bubble of liquid nickel and iron, what would be the major problems with this?
I'm working on a setting for an RPG, and I'm trying to build my planet so it's unique and interesting, but also semi-plausible. My question is, could you have a planet in stable orbit around a mag...
I have a hypothetical world in the works and I have a rough idea of what it might be like. My idea is that the planet was life-supporting with a widely varied biosphere. The magnetosphere failed a...
I was thinking about how an MRI uses a strong magnetic field to align the spins of hydrogen atoms in the body. What I was wondering about was if the human body experienced a magnetic field much st...
So for the story I'm writing, I'm designing is a gas dwarf with a very strong magnetic field and a planetary ring with a slightly inclined orbit. However, the rocks within the ring are very sensiti...
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...
It has been determined by observation of the stars that the gravity on Flat Earth is due to it accelerating upwards at 1G. This is what holds people and objects to the surface. It has also been det...
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 ...
What is the most powerful magnetic field that could be generated by a planetary object? The measurement of 'powerful' will be field strength ($\mathbf{B}$-field) at the planet's surface, in teslas....
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...
If I push a couple of magnetic asteroids into mars gravitational field, could they form an interlocking series of magnetic fields able to protect mars from solar winds? Size limits for asteroids ...
To my understanding, part of the reason life is able to exist on Earth besides its ozone layer is due to its magnetic field, which protects the planet and its life against solar winds and keeps the...
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...
