Antimatter :: physics antimatter matter

What is Antimatter? Albert Einstein came up with the famous equation, E=mc^2 And thus defined mass as highly concentrated energy. With sufficiently high concentrations of energy, that energy can form matter. However when this matter is created it is balanced out by the creation of antimatter. When matter and antimatter come into contact they annihilate each other and release large amounts of energy. A teaspoon of antimatter, reacting with matter, would run a car continuously for 100,000 years. Not all particles have equivalent or rather, separate antiparticles. The electron and proton, as well as quarks, have antiparticles, such as the positron and antiproton because they have a charge to reverse. The neutron has an antiparticle because, although it has no charge, it has a magnetic moment to which the antineutron is opposite. The photon, however has only mass and directional velocity, thus there is no antiphoton. Protons and neutrons also have a baryon number and their antiparticles have an equal but opposite baryon number. The History of Antimatter The existence of Antimatter was first predicted when Paul Dirac combined quantum theory and special relativity in one equation. This equation, however presented two 'solutions' to the electron. Dirac interpreted this to mean that not only was there an negatively charged electron, but there was a positively charged antielectron which had all the characteristics of an electron but an opposite charge. In 1932 Carl Anderson detected the first antielectron. While studying the tracks of cosmic particles Anderson noted a track left be something with the exact same mass as an electron, but with a positive charge. It wasn't until 1955 that the first antiproton was detected. This discovery rested on the Ernest Lawrence's creation of the Bevatron which could accelerate two protons and collide them at energies of 6.2 MeV (Mega electron Volts). The detection of the antineutron came 5 years later in 1960. It wasn't until 1955 that the first antiproton was detected. This discovery rested on the Ernest Lawrence's creation of the Bevatron which could accelerate two protons and collide them at energies of 6.2 MeV (Mega electron Volts). The detection of the antineutron came 5 years later in 1960. The next step in testing the symmetry between matter and antimatter was resolved concurrently by CERN and the Brookhaven National Laboratory in 1965 with the creation of the antidueteron. A deuteron is a nucleus from by a proton and a neutron, the antidueteron was formed by combining an antiproton and an antineutron. Antimatter :: physics antimatter matter What is Antimatter?
