* Antimatter may sound rare and extremely dangerous, but actually it's quiet common. For example beta decay, one of the forms natural radioactives slowly radiate away, always produces anriparticles. Powerdul enough gamma radiation ie photons may also create positron electron pairs upon being absorbed. The reason, this doesnt cause a catastrophy is that the masses involves are absolutely minuscule. For example it takes six times ten to the power of twenty six protons to make a gram. Thats about how many grains of sand are estimated to be in the Sahara desert.

A classic staple of science fiction and superhero stories, [[http://en.wikipedia.org/wiki/Antimatter anti-matter]] is matter composed of antiparticles, subatomic particles that have mostly exactly the same properties (mass, intrinsic angular momentum, etc) as your everyday particles, but some properties are inverted: antiprotons are negative, antielectrons (also known as positrons) have a positive charge, antineutrons and antiprotons have negative baryon numbers, etc. In some cases (photons, neutral pions) the particle is its own antiparticle.

* In the IncarnationsOfImmortality novel "Bearing an Hourglass", Satan sends Chronos on a fantastic journey. Since Chronos lives backwards, Satan claims he has sent Chronos to a Contra-Terrine (i.e. antimatter) galaxy where, Satan claims, time runs backwards so Chronos can interact normally. Chronos himself is protected by his time cloak. It turns out [[spoiler:Satan's lying, bigtime. Chronos was really sent to a movie studio Satan owns and interacted with scripted, magical movie sets]]
* The primary MacGuffin in Dan Brown's ''AngelsAndDemons'' is an Antimatter bomb. Also, read [[http://public.web.cern.ch/Public/en/Spotlight/SpotlightAandD-en.html CERN's commentary on the book]], it's quite enlightening.

* Antimatter warheads are ''one'' of the proposed explanations of the "reaction weaponry" in ''Anime/{{Macross}}''. Authors stated that they initially wanted to use straight-up nukes, but due to [[NuclearWeaponsTaboo the cultural conventions]] couldn't show ''the good guys'' [[NukeEm nuking '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 is ''also'' 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.

* Antimatter is the fuel of choice for starships in ''VideoGame/StarControl'' and mentioned by Commander Hayes to be expensive to make -however the Melnorme sells it quite cheaply-. It also powers the Utwig bomb [[spoiler: that you must use to destroy the Sa-Matra]], and oddly enough can be found as an exotic ore on certain planets.

* The plot of ''Manga/AssassinationClassroom'' all traces back to [[spoiler:the BigBad Shiro trying to utilize antimatter as a new form of energy by producing it from living humans. Koro-sensei is the result of a captured MasterAssassin who was unwillingly forced into the experiments, with his body converted into gelatinous tentacles to contain the antimatter. Ultimately, the issue arose that the antimatter would continue past the subject's cell division to catastrophic levels, as a mouse that underwent the same procedure blew up the moon where it had been secluded in fear of such an event.]]
