Antimatter - Essay ExampleFor the electron, for instance, there should be an antielectron superposable in every way just now with a positive electric charge. In his Nobel Lecture, Dirac speculated on the organism of a completely new Universe made out of antimatter (The History of antimatter, 2001)In 1932 Carl Anderson, a new-made professor at the California Institute of Technology, while studying showers of cosmic particles in a spoil chamber discovered antielectron, He c tout ensembleed the antielectron a positron, for its positive charge. After almost 25 years in the year 1955, antiprotons were discovered followed by antineutrons in 1959.In 1965, a unique mould at CERN (Conseil Europen pour la Recherche Nuclaire), a European organization for nuclear research called starting time Energy Antiproton Ring (LEAR) was engaged to successfully produce antihydrogen atom, which is a real a real antimatter atom. The brain piece of ass this is to trap these antihydrogen atoms by first slowing them down and then carry out unblemished comparisons of properties of hydrogen and antihydrogen particles.Matter and antimatter are entire opposites. So perfect, in fact, that when the meet they annihilate leaving behind a flash of pure goose egg. Nothing else remains antimatter annihilation is the eventual(prenominal) clean source of energy. It is the perfect conversion of mass (m) into energy (E) according to Einsteins famous prescription E= mc2, where c is the speed of light. The trouble is, however, that antimatter cannot simply be harvested or mined. It has to be made, and making it requires vastly more energy than annihilating it produces. every(prenominal) the antimatter produced at CERN in a year would provide barely enough energy to power a light bulb for a few seconds. (Gordon Fraser)Antimatter ApplicationsAntimatter may be the stuff of science fiction but at laboratories like CERN it is a commonplace tool for research. In hospitals and industry too, antimat ter is in everyday use for diagnosis. Positron Emission Tomography, PET, for example relies on antimatter. It works by attaching radioactive atoms that emit positrons - anti-electrons - to biological tracer molecules that find their way to specific areas of the body. When the radioactive atoms decay the positrons they emit immediately annihilate with electrons and the resulting flash of energy appears in the form of two gamma-rays of equal energy. These escape from the body back-to-back and are detected, allowing doctors to follow what happens to the biological tracer molecules and thus learn valuable information about the workings of the body. (Antimatter Decelerator, 2008).Negative and Positive sides of Antimatter The eighties US Strategic Defense Initiative program (better known as Star Wars) included several projects which looked at the possibility of using antimatter as rocket fuel or to drive space-borne weapons platforms. (Gordon Fraser)Antimatter, converting all its mass in to energy, is the ultimate fuel. However first the antimatter would have to be manufactured - there is no mine of antimatter. (Gordon Fraser)Antimatter is difficult to produce - all the antiprotons produced at CERN during one year would supply enough energy to light a 100 watt electric bulb for three seconds (Gordon
