A classic staple of science fiction and superhero stories,anti-matter is matter composed of antiparticles, subatomic particles that have exactly the same properties (mass, intrinsic angular momentum, etc) as your everyday particles, but opposite charge: antiprotons are negative, antielectrons (also known as positrons) are positive, etc. In some cases (photons, neutral pions) the particle is its own antiparticle.

Antiparticles do exist naturally; however,antimatter normally only exists for brief moments before coming in contact with normal matter, and it can only be formed as a product of radioactive decay, or when particles collide at very high speeds. When electrons encounter positrons, both particles mutually annihilate and emit gamma radiation (at high energy, they can produce other stuff). When protons and neutrons encounter antiprotons and antineutrons, they also annihilate, resulting in a star of pions shooting out. These ultimately decay into high-energy gamma radiation. The result is many times more powerful than nuclear fusion (relative to its mass; it's the purest example of Einstein's famous equation E = mc²). Antimatter is often used as either a fuel or a weapon in fiction, both cases due to its high energy potential.

How high energy? One gram of matter, converted to energy with 100% efficiency, creates 90 terajoules of energy.^[1] Compare to "Little Boy", the nuclear weapon used against Hiroshima in 1945, which was built from64 kilograms of uranium and released only 63 terajoules. (So basically,Hiroshima as a Unit of Measure is approximately 0.1% matter-to-energy conversion potential.)

As noted on theKinetic Weapons Are Just Better page, you have to get something of massm whipped up to 87% the speed of light to have the same amount of energy as a matter/antimatter reaction where both the matter and antimatter that you're annihilating have a combined mass ofm.

One of the big mysteries concerning the Big Bang has been why there is so much matter in the universe but not nearly as much antimatter, since all known processes for creating massive particles create both in equal quantities. The weak interaction (that describes processes like beta radioactive decay and such—it's also where the now famous Higgs mechanism takes place) explains how a there might be a small imbalance in the amounts of matter and antimatter, but that imbalance is not nearly enough to explain the existence of... nearly everything we care about. The strong interaction (that describes how protons can stick together in a nucleus even if they have positive charge) would be a nice candidate to do it, but that's much more easily said than done. So, yeah, we have no idea.

The explosive aspect of antimatter is also often explored, usually in the form ofplanet-destroying weapons. Alternatively, controlled matter/anti-matter reactions could be used as a source of power: given that it does not naturally occur in useful quantities, it would be something like an ultimate battery - with massed solar or nuclear power producing the energy needed to synthesize large quantities of antimatter for use as starship fuel, weapons, or any application needing very high energy/power density.

Don't hold your breath waiting for such marvelous feats of technology, however: antimatter is currently the most expensive stuff on Earth, priced at about $62.5 trillion a gram. Not that a gram of antimatter was ever produced—in fact, so far we don't know how to effectively store it. Put it in any regular container and it would annihilate against its walls. No good. Electromagnetic traps for have been devised, but those can only store a billion antiprotons or so. That's one millionth of a billionth of a gram. Ish. More than this would be difficult because all these antiprotons have negative charge, and hate being close to each other. Alternatively, we could store antihydrogen atoms which are electrically neutral, but that also makes those electromagnetic traps much more difficult to use. Still, scientists have been able to store 309 antihydrogen atoms for more than 1000 seconds. Now all we need to do is store one trillion billion (ish) times more hydrogen. No small feat—butScience Marches On.

Of course, instances in which a series gets the known properties of antimattercompletely wrong are also not uncommon.

A common form ofUnobtainium.

Anime andManga

• Perhaps the most famous depiction of antimatter in anime is that ofEvangelion Unit 01 shooting down theAlien Geometry Angel Remiel with a giant positronic sniper rifle. The fact the beam should explode as soon as it hits the air is glossed over in the show, butsupplementary materials suggest the positrons are "jacketed" with a neutrino field. Thismakes no sense at all, butlet's all just go with it.
• InNadia: The Secret of Blue Water the engine powering the Nautilus runs on antimatter, in the show described as "particleannihilation." There is a dedication plaque in Atlantian language declaring theNautilus is actually the starshipEritrium, recycled as a submarine.
• Starships inCrest of the Stars use antimatter as fuel, much as inStar Trek.
• The tendency of antimatter to annihilate air molecules it comes in contact with is actually used inGundam Seed, where theCool Ship fires its positron canons ahead of it when heading back into space to clear out air resistance. Called, "Positronic Interface."
  • And then we havethe moment whereMu La Flagacompletely blocks an antimatter cannon with his Gundam's shield, protectingthe Archangel. When asked, the director first said the shield's anti-beam coating stopped it; when it was pointed out that the weapon was antimatter, he admitted that he forgot that part.
• The titleSuper Robot ofCannon God Exaxxion is powered by an antimatter reactor. According to theBackstory, the aliens who created it were said to have found an asteroid made of the stuff, which they harvested for fuel until its orbit decayed and it crashed into the nearest planet and practically wiped out their civilization.
• Imperialdramon ofDigimon Adventure 02 has an attack called "Positron Laser". Like inEvangelion, it's not explained how the beam doesn't blow up as soon as it leaves the cannon. Although in this case, it's more likely to be just a cool-sounding name and the beam has about as much to do with positrons as it does with lasers.
• Antimatter warheads areone of the proposed explanations of the "reaction weaponry" inMacross. Authors stated that they initially wanted to use straight-up nukes, but due tothe cultural conventions couldn't showthe good guysnuking 'em right and left. So they thought up a fancy new name, and later proposed AM as an explanation (which is really the same, as antimatter annihilation isalso a nuclear reaction, just other type than most well-known fusion and fission). Nowadays, as the taboo is weaker, they often just plain call them nukes.

Comic Books

• TheJustice League'sEvil Counterpart, the Crime Syndicate, comes from an antimatter universe. (To travel into a positive universe and back, they must switch the polarities of their particles mid-course.)
• Pre Crisis, the antimatter universe Earth was rather the planet Qward, as the Crime Syndicate lived in one of the matter universes. Post Crisis, both the Crime Syndicate Earth and Qward are worlds in the same antimatter universe.
• InDC Comics' 1986Crisis Crossover,Crisis on Infinite Earths, an antimatter wave erased several universes from existence- without exploding or disintegrating itself in the process. It was brought about by another antimatter Evil Counterpart too.
• TheMarvel Universe has the "Negative Zone" dimension, which is made of antimatter (though there seems to be some positive matter in it as well.)

Fan Works

• The fear that ignorant wizards might be able to transfigure or conjure antimatter drives Hermione Granger to push the limits of Arithmancy, in the process discovering a new exemption to Gamp's Law, in theHarry Potter fanficThe Arithmancer.
• In theMega CrossoverNo Tendo, antimatter can be made and contained by humans thanks to tech shared bythe BOLO, a mountain-sized AI tank encountered on a planet reached by thestargate. And what appears at first to be a simple throwaway detail about the benefits of working with the BOLO turns out to be the weapon that packs the biggest punch against Heru'ur's fleet.

Film

• The Rocky Horror Picture Show: "Yes, Dr. Scott. A laser capable of emitting a beam of pure anti-matter."
  • "Then it'snot a laser."
  • Alternatively, "Then itdoesn't matter!"
  • In a bizarre case of life imitating art,this article describes a recently-discovered process by which a laser can be used to produce a surprisingly large amount of antimatter.
• The Giant Claw has an antimatter shield that destroys anything the military fires at it.Why it doesn't explode the air is never addressed.
  • The air molecules were probably too busy laughing at the ridiculous giant buzzard to notice the antimatter.
• A blatant misuse of the term appears in the original 60sBatman film. The villains de-hydrate some of their mooks and smuggle them into the Batcave, where they are re-hydrated. A single punch from Batman or Robin makes them instantly disappear because of flaws in the re-hydration process (they had accidentally used heavy water from the atomic pile). Batman's scientific opinion? They were reduced to "anti matter".
• The plot ofSolar Crisis concerns theflinging of an anti-matterbomb to cause apre-emptive solar flare.
• Asimov's positronic robot brains are retained in some films based on his work (I Robot,Bicentennial Man).

Literature

• Isaac Asimov's robots had "positronic" brains, something which Asimov himself would later admit was both ridiculous and impossible once positrons in particular and robotics in generalbegan to become understood. His stories continued to use positronic-robots for years after his admissions, but solely becausethey were within the already-existing universe.
  • Given some of Asimov's descriptions of how positronic brains worked, it would have been entirely reasonable toRetcon these positrons as merely holes (in the semiconductor sense) — especially considering that Dirac's view of positrons as "holes in the sea of negative-energy electrons" was still pretty kosher when Asimov started writing his robot stories.
  • The initial point of "positronic" brains was that the matter-antimatter interactions would be so quick that they could mimic the speed and complexity of human brains. It's doesn't make sensethese days, but it was passable at the time.
• The primaryMacGuffin in Dan Brown'sAngels & Demons is an Antimatter bomb. Also, readCERN's commentary on the book, it's quite enlightening.
• E. E. "Doc" Smith'sLensman universe had arather early (late 1930s) example of antimatter bombs, butthey worked a little differently than we'd expect. His "Negative Matter" was said to consist ofDirac positrons, had negative mass, and some other properties that perhaps hinted at negative energy. Later research has treated antimatter quite differently. It did still cause mutual annihilation with matter roughly as modern science would expect, however, producing copious amounts of hard radiation in the process.
  • Smith didn't think the implications through, though—the gamma rays were treated as a nuisance side effect, not a far-more-deadly weapon in their own right.
• The Night's Dawn Trilogy by Peter F. Hamilton features antimatter as a crucial plot point. In the setting of the series, antimatter exists in a practical form, usable as an exceptionally high-yield fuel for propulsion, generating energy or blowing things up. Antimatter is so effective, however, that is has been outlawed and carrying, using or manufacturing antimatter is investigated and punished by the Confederation. The ban was put in place when antimatter bombs were demonstrated to be especially effective at destroyingplanets. Still, black market manufacturing stations produce and distribute antimatter.
• Jack Williamson'sSeetee stories were written around antimatter—called "Contra-Terrene" (C.T.) in the stories. InSeetee Shock it is used to fuel a power station broadcasting free energy to the entire Solar System, breaking the back of the corrupt mega-corporation Interplanet. InSeetee Ship concentrations of antimatter (such as the titular spaceship, built by antimatter aliens) are found to have an unusual property; they movebackwards through time!^[2]
• Aside from occasional use in weapons and as a power source,Perry Rhodan once featured aliens from an antimatteruniverse as peaceful but explosive visitors. (The science was a bit dodgy at the time, with any given chemical element supposedly only reacting with its corresponding anti-element...but the destructive potential of unprotected contact was played to the hilt.)
• OneChoose Your Own Adventure book involved thePlayer Character meeting an "antimatter" version of themselves, created as a side effect of theBig Bad's actions. Most of the endings involved the PC and their anti-self touching each other and ending all existence through the violent release of energy.
• InMikhail Akhmanov'sArrivals From the Dark series, several advanced races use antimatter as their primary (in some cases, only) ship-to-ship weapon. The first novel,Invasion, shows just how superior antimatter is to weapons used up until then by humans: missiles (both conventional and nuclear), plasma cannons, and swarms (like mass drivers but shoot a spread of icicles at high velocity). This forces humans to use thisImported Alien Phlebotinum in later books, although the fourth book,Dark Skies, shows that even plasma can be effective if used insufficient quantity (i.e. a fleet of plasma-armed ships obliterates a relatively small human battle-group armed with antimatter weapons).
  • The books also make it a point that antimatter isnever used on a planet, as it would more likely kill you and everyone around you than the enemy.
  • The last novel of the series has humans bombarding planets from orbit using antimatter weapons. It takes an hour for a cruiser armed with two turret-mounted annihilators to turn an Earth-like world into a charred rock. The book specifically mentions that this is almost never done, though, as Earth-like worlds are rare, and nobody likes wasting them. The only reason this is done is in an attempt to stop a war with a race ofReptilians by destroying their leaders (they are hardwired from birth to obey a strict hierarchy).
  • Interestingly, the novels fail to explain how antimatter weapons can damageDeflector Shields. After all, they're not made of matter and, as such, would not interact in an explosive fashion with antimatter. Antimatter should be as harmless as space dust to shields. So much for an author with a physics background.
• Antimatter is an extremely-dangerous weapon inAndrey Livadny'sThe History of the Galaxy series of novels. It is a WMD, as it can annihilate armadas, as well as small moons. Apparently, in the 1000 years of using the weapon (extremely sparingly), scientists have not figured out how to control the yield.
  • One of the novels,The Backup Spaceport, features newStiletto-classSpace Fighters powered by an antimatter reactor (all reactors before were fusion-based). The difference is that it does not use regular antimatter but the so-called "Vetletsky antiparticles", which only react with tritium. This ensures that, even if antimatter containment is lost during battle, the ship is not destroyed by matter/antimatter reaction.
• In Alastair Reynolds'Revelation Space (and itsuniverse), antimatter weapons are small, hard to get, andextremely destructive; one character has the bombsimplanted in his eyes (the eyes are artificial) and can destroy the planet. Since Reynolds is an astronomer and writes fairlyhard science fiction (except for theCosmic Horror Story elements), this is all pretty well justified.
• One story inLarry Niven'sKnown Space universe concerns a visit to a planet that - unknown to the explorers - is made of antimatter. In a later book, it is discussed that the crew of a ship armed with antimatter weapons will expend their ammo at the first possible justified opportunity, for their own safety's sake.
• InDragonriders of Pern, the ships that brought the original colonists to Pern had antimatter-fueled drives, and remained in orbit after being stripped of anything useful. This comes into play inAll the Weyrs of Pern, when those same two-thousand year old engines are deliberately detonated in an attempt to alter the Red Star's orbit.
• In theHumanx Commonwealth novelThe End of the Matter, aLost Superweapon is used to eliminate the threat of a rogue black hole by summoning a "white hole" composed of antimatter fromAnother Dimension; the two then begin a process of mutual annihilation over hundreds of thousands of years. It is noted by one of the awed protagonists that it was a good thing they didn't try to set off the device inside the black hole, or the entire process would have occurred at once.

Bran Tse-Mallory: "I've always wanted to see aquasar, but not from up close!"[3]

• TheSten series has Anti-Matter Two, which is technically not antimatter as we know it but an alternate-universe equivalent with similar properties. It is used to power starship engines and as ammunition in weapons (ranging from the tiny amount in Willygun bullets to the large amount inplanetbuster missiles).
• TheUplift series features antimatter beams as merely one of a truly staggering variety of weapons employed by Galactic races. When you have weapons that alter probability or shunt you into another universe, mere antimatter seems tame by comparison.
• The Culture uses CAM - compressed anti-matter AKAanti-neutronium
• InSergey Lukyanenko'sA Lord From Planet Earth trilogy, anti-sodium and anti-helium are used by the protagonist in the second book during a space battle. The enemy ship, however, figures out how to defend against each attack.
• Martin Gardner'sThe Annotated Alice goes into a rather amusing digression over Alice's concerns about whether or not milk from the Looking Glass world is safe to drink. While much of it is devoted to the concept ofMirror Chemistry (and is indeed one of, if notthe most familiar examples of the topic in the popular consciousness), Gardner also speculates that Looking Glass milk could be made of antimatter. Either way, Alice's worries are pretty well justified.
• InThe Killing Star, we detect incoming alien speceships by looking for the presence of 0.5 MeV gamma ray photons—photons emitted when positrons and electrons annihilate each other in an antimatter rocket engine.
• The ships inTour of the Merrimack use antimatter reactors. This poses some tactical problems; you can't shoot down a ship in atmosphere without the risk of causing a massive antimatter explosion.
• Antimatter is used as a power source inInfinity Beach, but it is carefully regulated. The novel begins with a massive explosion apparently caused by antimatter of unknown origin.
• Dread Empires Fall has this as both fuel and warhead. In fact, missiles burn fuel until they reach their target, and whatever's left goes into exploding. It's one of the few justified cases ofArbitrary Maximum Range. It also one of the factors that contributes to the missiles having a very short tactically-viable range, in conjunction with point defense.
• Antimatter rockets are a popular propulsion method inRobert Reed'sGreat Ship universe. Since it's so effective at pushing the ships, they need only a relatively tiny amount for interstellar voyages.
• Some stories from theStar Wars Expanded Universe featurepositronic processors (likely an AsimovShout-Out).

Live-Action TV

• An episode ofLost in Space also had an evil counterpart of John Robinson (played by the same actor) from an antimatter universe, but no explosions.
• TheDoctor Who serialPlanet of Evil also features antimatter treated more as a radioactive substance than an explosive one.
  • In another, the Doctor claims that an antimatter explosion will turn everyone into "un-people, un-doing un-things un-together." Which is almost certainly wrong, if only because it's very hard to figure out what it's supposed tomean.
  • Easy: It means they're dead.
  • Omega, in "The Three Doctors" is trapped in an antimatter universe on the other side of a black hole.
• Antimatter is a common source of energy inStar Trek.
  • Typically, it is used as a fuel to powerwarp drives and other energy-intensive apparati aboard a starship (such as energy weapons, shields, base power load for the whole ship). According to theStar Trek: The Next Generation Technical Manual, the warp drive is powered by colliding beams of deuterium^[4] and anti-deuterium, regulated by a shapeddilithiumcrystal under extreme heat and pressure into an energy form that can be harnessed.
  • On occasion, it's used as explosive energy: 'photon' torpedoes are per canon loaded with this stuff and normal matter, sent over to another ship, and BOOM. Well, they're supposed to, anyway.
    • And in the episode "Obsession", it's used for a demolition charge. One ounce of antimatter reacting with matter supposedly produces an explosion thatblows half the atmosphere off an Earth-like planet. While the basic idea of an antimatter bomb isn't too far off,the numbers certainly are; in reality, an ounce of antimatter annihilating an ounce of normal matter would, as a bomb, have a yield of only a couple of megatons. You'd need at least some millions oftonnes of antimatter to get the kind of effect they describe.
  • InStar Trek: The Original Series episode "The Alternative Factor", there are two versions of Lazarus, one made of matter from our universe and one made of antimatter from a parallel universe. If they ever get together in either universe, both universes will be destroyed. This would not happen in real life, although you'd get a sizable explosion.
  • In another TOS episode, "The Doomsday Machine", the titular planet-eating menace fires a beam that Decker described as "Pure antiproton, absolutely pure!"
    • Which should not damage a starship with workingDeflector Shields. Antiprotons would have no reason to interact explosively with an EM field (or a graviton field, depending on which fluff explanation you prefer), although they would certainly wreak havoc if they touched the hull underneath.
  • InStar Trek: The Next Generation, android Data has a "positronic brain" in a deliberate homage to Asimov. Having Star Trek levels of technology still makes the concept no more plausible, though.
  • In "The Best of Both Worlds", Riker's plan to kidnap/rescue Locutus/Picard from the Borg ship involves lighting off an antimatter spread, which is essentially a giant fireworks display to give cover to the infiltration shuttle carrying Worf and Data.
• In the season 2 premiere ofWarehouse 13, antimatter is stolen from CERN to power one of the villain's inventions.
• In an episode ofBuck Rogers in the 25th Century, a character who can teleport is badly injured from contact with asingle particle of antimatter.
• In an episode ofEureka, a device is activated by the mere presence ofcontained antimatter nearby, when both are stored in a bank vault. Apparently a town full of geniuses can't figure out that antimatter by itself isnot an energy source nor is it radioactive. It appears to be a greenish liquid stored in a test tube. Unless you want it to blow up, it should be stored in a vacuum environment kept away from the container walls by a magnetic field.

Music

• InBrave Saint Saturn'sAnti-Meridian (the third part of a sci-fiRock Opera trilogy), the crew of theUSS Gloria serendipitously discovers a relatively cheap means of producing antimatter. By the album's end, this discovery has solved Earth's energy woes and revolutionized space travel.

Tabletop Games

• GURPS: Ultratech briefly discusses antimatter. One microgram is enough to vaporize a normal human and incredibly expensive. There are also stats forantimatter bullets.
• ACthulhu Tech supplement had a weapon fired antimatter at relativistic speeds after burning a vacuum in the air with a laser.
• InTranshuman Space, antimatter is manufactured on Mercury, using solar energy to drive the particle accelerators, and used among other things to catalyse the most advanced fusion drives.
• InStarfire, starship missiles can be fitted with ordinary nuclear warheads, or with antimatter warheads. Antimatter warheads are more powerful, but are also much more dangerous to the ship carrying them. If an enemy destroys a ship's missile hold, the unfired nuclear missiles stored in it will simply be destroyed and become useless, but the unfired antimatter missiles in it will detonate.
• Mutants and Masterminds has Negator, a villain who first emerged when his Earth-Prime counterpart got forcibly merged with his counterpart from an antimatter universe (similar to the Crime Syndicate example above). Some scientific credence is given to the concept, noting that if the thin yet resilient force field that keeps the two halves separate yet functioning is ever nullified,bad things happen.
• In oneParanoia mission, the PCs discover along-forgotten antimatter bomb capable of destroying the entire Complex, and have to keep it away from fanatics who would actually detonate it.

Video Games

• TheGalactic Armory mod forStar Ruler adds antimatter generators, thrusters, and weapons. Antimatter has the advantage of needing tiny amounts of fuel storage, it has the most efficient and nearly most powerful thrusters, and the antimatter weapons are devastatingly powerful. However, the generators are extremely expensive, and very,veryfragile. Ships carrying antimatter tend to explode violently when their armor is breached.
• Pokémon Diamond and Pearl:Word of God states that theLegendary Pokémon Giratina is supposed to be the living personification of antimatter, and that it and its world are constructed of antimatter. Functionally, Giratina switches forms when in your world - Earth (or Poke-Earth, whatever) - and its original state only occurs in its own world, unless you go back into its world and bring back theGriseous Orb, which lets it retain its natural form.
• Traditional capship power source, in theWing Commander universe. Also used on the Excalibur and its descendant, the Dragon.
  • Several capital warships also use anti-matter guns to engage targets, occasionally to the player's chagrin given that only one or two blasts are required to destroy their fighter.^[5]
• Sam and Max: The Devil's Playhouse hasSam and Max destroy the entirePenal Zone with an "antimatter bomb".
• InSword of the Stars, Antimatter is the final level of reactor technology development. Strangely, however, M/AM ships have very small explosions compared to normal ones, even though Antimatter is far more destructive when uncontained. There are also antimatter weapons. Developers have stated that they will not be inventing any new power source beyond Antimatter for the sequel, but instead have techs that optimise its use.
• The aliens inUFO Alien Invasion use spacecraft powered by anti-matter.
• InMetroid Prime 2, the Annihilator Beam, appropriately enough, is stated to fire an annihilation reaction of matter and antimatter.
• InShadow the Hedgehog, the "Diablo" mech has an attack called "antimatter cannon" which looks more like an expanding energy field.
• InMass Effect, military starships are propelled by matter-antimatter reactions created by combining antiprotons with hydrogen atoms. The stations that produce them are high-value targets in wartime. Antimatter is also used as a weapon similar to nukes, but are much rarer in comparison and strictly regulated.
• Super Robot Wars W: The Earth Federation never gets the N-Jammer Canceler technology, which played an important role in the plot ofGundam Seed by allowing the Federation to use nuclear weapons. In the game, antimatter warheads are substituted for the nukes as needed.
• InStar Ocean: The Last Hope an alternate earth is destroyed by an unstable antimatter engine.
• InEVE Online, hybrid weaponry such as blasters and railguns can be loaded with anti-matter charges, there are readily available anti-matter warheads for everything from dumbfire rockets to super-capital torpedos, and Gallentean spaceship technology uses anti-matter as a fuel source.
• InWing Commander, M/AM plants are the primary powerplant for capital ships, and also serve to power theExcalibur andDragon superfighters in WC3 and WC4, respectively.
• InX-COM: UFO Defense, the aliens use Antimatter as a power source for their weapons and UFOs. Said Antimatter is generated by analien element called Elerium-115.
• InSins of a Solar Empire, ships that have special abilities use Antimatter asMana.
• Free Space has two missiles that use Antimatter warheads in the first and second games, called the Tsunami Bomb and Helios Torpedo, respectively.
• A sign on the wall inPortal 2 advises you to:

Know your allergens. Pollen. Animal Dander. Plastics.Antimatter.

• In the two most recent games in theX-Universe series, the Terran corvette weapon is the matter/antimatter launcher, a coilgun that fires a bomb containing matter and antimatter separated by a force field. When the force field is compromised by impact or by reaching the end of its range, the matter and antimatter mix withthe usual result. According to fluff, Terran ships also use matter/antimatter for power generation.
• Protoss Scouts inStarCraft are armed with antimatter missiles for air-to-air combat.
• In the Polaris questline inEV Nova, you can equip your ship with a matter/antimatter reactor.The Polaris are several centuries ahead of the rest of humanity technologically; everyone else uses fission (either traditional or liquid-thorium-fueled).

Web Comics

• Antimatter is used in explosives inSchlock Mercenary, usually consisting of minuscule amounts of antimatter encased in fullerene molecules - breaking these up will cause a massive explosion. Most notably, a minor character once smuggled antimatter out of a facility in paper bags. ResidentMad Scientist Kevyn turned his uniform insignia into an antimatter grenade, whichwhen used, destroyed an enemy base, and though indirectly, brought downa spaceship in orbit of the planet.

Web Original

• Darwin's Soldiers has an Anti-matter universe. The ability of this universe to interact with our matter universe isdependent on plot necessity.
• Antimatter inOrion's Arm is generated by massive orbital "farms" and usually used in engines.
• Antimatter is central toThe Pentagon War. Hyper Bombs require 250 kilograms of positrons, and the starshipMercurand carries 100 tonnes of antihydrogen as fuel.
• Anti matter can be used magically inChaos Fighters and they are coated with magic to prevent reaction with air molecules.
• Tennyo from theWhateley Universe is half made of antimatter.

Western Animation

• OneScooby-Doo special has an antimatter-powered car explode.
• The Mondays, the evil versions ofThe Secret Saturdays, supposedly come from an antimatter universe. "Mirror Universe" and causing the laws of physics to become corrupted describes it effectively. And this is a show that actually had some impressive sci-fi concepts.
  • They actually use the real effect of Antimatter whenArgost absorbs the Antimatter powers of Zak Monday and the Matter powers of Zak Saturday, despite Zak's warnings not to do so.He should've listened.
• The Specialists, of a series of shorts on MTV'sLiquid Television, met their antimatter counterparts, who were chromatically opposite but otherwise identical. Typically, the short plays loose with the properties of antimatter.

Real Life

• PET scans rely on antimatter to work. The subject is injected with a radioactive tracer substance that emits a positron when it decays. When the positrons annihilate nearby electrons in the body, gamma rays are released that the machine can detect.
• According tothis article, physicists at Lawrence Livermore Labs have developed a way to create large numbers of positrons by shining the lab's Titan laser at a gold target. They use one of themost powerful lasers ever built to makeantimatter. Fromgold.
• While pure antimatter weapons are still a pipe dream, there has been talk of using antimatter components as a trigger in more conventional nuclear weapon designs to greatly increase their power and/or compactness—perfectly sound as far as the theoretical side goes. Still expensive, but less so than a pure antimatter weapon due to the lesser amounts of antimatter required. Also because a pure antimatter weapon is necessarily fail-deadly, while such a nuclear hand grenade is not.
• Antimatter in the form of antineutrinos is very common; it can be produced by many nuclear reactions. However, neutrinos tends to ignore normal matter. And when we say "ignore", consider this: The nuclear reactions taking place in the core of the sun produce both light and neutrinos. Thelight takes somewhere between 10,000 and 170,000 years to work its way to the sun's surface. Theneutrinos, on the other hand, exit the sun at the speed of light without interacting with any of the material in the wayat all.
  • A few centimeters of lead will block half of the incident gamma rays. It would take a few light-years of lead to absorb half the incident neutrinos. On the rare occasions they do interact with normal matter (and with enough of them, they eventually will) they induce a beta-decay in the target (even if it wouldn't normally be able to beta-decay). Neutrinos convert a neutron into a proton and an electron.
• Electron - positron colliders were quite common in physics.
• To study normal matter, physicists like to use particle accelerators. To study antimatter, physicists use anantiproton decelerator.
