Science in Seconds - Antimatter

Science in Seconds Know Everything RUMOURS - Antimatter Torah Kachur: Everything has an opposite, the yin to the yang, the black to the white, the Betty to the Veronica, and it's no different than with matter. Some theoretical physicists, like Dirac, thought matter would be lonely out there in the universe, so they proposed its partner, antimatter, the opposite or mirror-image of matter. Antimatter is created in a lab, wherever high-energy collisions take place, resulting in positrons, anti-protons, and anti-neutrons, particles that are the opposites of the stuff of matter. But then, wherever matter and antimatter occur in the same place, they annihilate each other into high-energy gamma rays. So, although antimatter may be created, for instance, when cosmic rays enter the Earth's atmosphere, they rapidly come in contact with matter and destroy one another. (Cue passionate monk protecting the world from evil science) In the middle of the Milky Way there's a giant antimatter cloud that emits so much energy it is the equivalent to 10,000 suns, but it is unclear about the origins of this giant store of antimatter. New evidence from the integral gamma ray observatory has found this anti-cloud is lopsided, so lots of really smart theoretical physicists were wrong. It also means that the antimatter cloud was likely not produced by exploding stars, or supernova, but instead, is possibly produced from low mass x-ray binaries or stars being eaten alive by a larger neutron star, or black hole. Antimatter is important because it's cool, it explains behavior of matter in the universe, and it powers the Starship Enterprise. And where would we be in life without Captain Picard?
