How can a character explain baryon asymmetry (there is more matter than antimatter) by the universe being a simulation with a slightly imbalanced random number generator being employed at the point...
In the story I'm creating, a major weapon type of humanity will be Antimatter based weaponry. This is a fairly new technology, as antimatter production facilities have just reached the size and cap...
Antimatter gets used a lot in SciFi due to it's mind-bending energy density. If you can store it in a form that requires no power and is at least mildly idiot-proof then you've just solved half of ...
Are there any areas of space where an antimatter object, the size of a small house could survive without coming into contact with any or extremely minimal amounts of matter? I had assumed in all a...
In your space journey your ship systems have spotted an unusual source of gamma rays: it's the size and the mass of a planet and it has a pulsating behaviour. Further observations shows that you ...
The environment is set in (ideal) space with no air for the bullet to interact with. It should encounter nothing until it reaches its target. The bullet is assumed to be a perfect sphere with a di...
In a far future, antimatter is used for energy storage: Huge space stations with powerful solar arrays orbit the sun a bit inside Mercurys orbit, using the energy to create small amounts of anti-hy...
Let's say our villain fires an antimatter rifle from behind a magnetic field over a km from the target. The bullet is traveling over 1000 meters per second. If it reaches its target, the 13 gram bu...
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...
I've been thinking of the idea of creating and adding an alien species that's antimatter-based (being from a universe where antimatter became the majority instead of "normal matter"). However, I'm...
I was wondering if a vacuum created within a particular material in the shape of sphere could be used to harvest anti-matter from virtual particles? Within the vacuum, theoretically, virtual parti...
Say 200-300 years in the future, humankind has colonized much of the solar system, using a combination of laser thermal drives and solid-core nuclear rockets (fusion never really panned out). Sudd...
I have an idea for an extremely crackpot engine design for a future society I may incorporate into my story. What would happen is individual antihydrogen molecules injected into the center of car...
Now, taking out the cost to produce/collect it, assume somehow we perfected a formula or find a natural source (because that is currently very prohibitive), how feasible would be to use antimatter ...
A fictional starship that I am designing functions via a form of Bussard ramjet that uses hydrogen from the interstellar medium as reaction mass, not as fuel. In order to accelerate the propellant...
So I found the base of these pesky rebels on this planet and I am tasked with destroying the planet to eliminate the rebels once and for all. Unfortunately, my death star has malfunctioned and has ...
I am dealing with a dystopian story that tries to come up with some kind of total surveillence or control from higher authorities. The authorities threaten to kill those who disobey them by simply...
Supposing we had many thousands of antimatter bombs (they can be detonated in many different locations), how much total antimatter would we need in order to wipe out all humans on Earth? Supposing...
I've recently discovered something great: the Schwinger effect. It says that if you concentrate enough power thanks to laser into a single point in space, it will spawn a pair of proton and antipro...
In a previous question, it was established that antimatter could be "mined" through positron-emitting isotopes. By gathering positrons from decaying positron-emitting isotopes (potassium-40 and al...
Imagine we had an easy way to produce antimatter, we could use it for interstellar travel, deadly weapons or more; but I've thought: How could we use it to produce electricity? As Antimatter annih...
In the science fiction setting I'm working on, one of the factions are supposed to be using naturally occurring antimatter because the systems they reside in have sufficient natural sources of it. ...
Setting aside concerns of containment for now; how much energy would it take to create antimatter? And how much of it would we get back using it as a fuel in a matter-antimatter reactor? What I'm ...
So aliens have arrived in the solar system. They have faster-than-light travel technology and the ability to handwave away the supposed causality violations that such an invention causes They're ...
I have an idea for a Sci-Fi story that involves a planet with a third moon made entirely of antimatter, before I delve further into this concept, I would appreciate input on how to make this sci...
Lets say I have this nice gun which can shoot a certain amount of antimatter. After hearing answers about why that won't work, I added a magical coating to the projectile making sure the antimatter...
Antimatter annihilation is the best source of energy per weight. However, antimatter is not readily available anywhere within reachable distance, it's insanely difficult to produce and contain. Ho...
Is it possible to contain similarly charged particles in a magnetic field or traps, in generally large scale (say, all of them have positive charge), and could be utilized as power reserves quite e...
How much wattage would you need to accelerate a four petaton spaceship by 1g for a year? This should be about enough to reach near light speed, which is perfect for interstellar cruising, but I'm w...
Assuming the wars of the far, far future aren't either fought exclusively by unmanned spacecraft/robots/drones or in ways so incomprehensible to us that comparisons are meaningless, the only foolpr...
I've been looking into anti-matter and a relatively realistic way to contain it through gravity in my story. I'm probably incorrect in the theoretical physics of the idea but, I'm imagining that th...
Forget about how we get it there, some kind of top secret experiment on mars gone wrong in all the right ways. If somehow Mars's core was mixed with some amount of antimatter, and assuming 100% of...
If half the earth was made antimatter and contacted the other half all at once, would the resulting energy be enough to "destroy" the observable universe? I did some math based on the mass of the ...
Consideration For the sake of argument, please assume the following: The planet in question is around the size of Earth The planet may contain native intelligent life, artificially engineered Th...
After writing this question, I came up with a new question. Consideration The considerations are mostly similar to the linked question (reading it is highly encouraged, as I am trying to post as...
