Topic in Depth - AntimatterFor every action there is a reaction, for every plus there is a minus, and for every matter there is well…antimatter. This topic in depth tackles the complex concept of antimatter, from the Big Bang to solar explosions and the technology to detect it.
Big Bang Science: Antimatter The United Kingdom's Particle Physics and Astronomy Research Council (PPARC) addresses the issue of why, if matter particles and their antimatter partners were created in equal amounts after the Big Bang, they did not eradicate each other. Visitors can learn about experiments taking place at many scientific research...
Antimatter Factory on Sun Yields Clues to Solar Explosions NASA argues that new observations may upset theories about how solar explosions create and destroy antimatter. Users can view the many colorful animations and short movies obtained from the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI).
Antimatter Wikipedia provides a simple, concise explanation of antimatter and discusses scientists' successes in producing anti-atoms of hydrogen and anti-deuteron nuclei. This online encyclopedia also offers links to many of the physical terms related to the topic so that novices can easily understand the material presented.
The Reality of Antimatter This website, created by Space.com, summarizes the findings and mysteries about the natural presence of antimatter. Through this online article, visitors with little knowledge of this phenomenon can learn about the scientific theories, its huge energy potential, and its lifespan.
The Buzz About Antimatter This site, created by Physics Central, educates users about the cloud chamber track of an electron-positron pair. There is an image showing how "as charged particles pass through the supersaturated vapor in this chamber, they leave behind a visible trail of tiny droplets." Visitors can learn how matter and...
What's the Matter with Antimatter? Particle Physics in Plain English!, an outreach project for the Lepton Photon 2003 Conference at Fermi National Accelerator Laboratory, discusses how particle physicists are studying antimatter with the hopes of contributing to the current understanding of the universe on all scales, "from revealing the origin of...
Huge Underground Detector May Explain Matter-Antimatter Riddle The Argonne National Laboratory discusses the potential for the new MINOS detector at Soudan to prove neutrino oscillation. Visitors can learn how the study could help in the understanding of why we live in a world made up of matter.
Antimatter: Mirror of the Universe Perhaps best known as the fuel for the warp drives of the starship Enterprise, antimatter was first theorized by physicist Paul Dirac in 1928. Created by CERN, the European Organization for Nuclear Research, this attractive site offers a helpful introduction to antimatter aimed at the general reader. Features include...
Stanford Linear Accelerator Center: Physicists Discover Dramatic Difference in Behavior of Matter Versus Antimatter This Stanford University website announces the significant findings by the physicists conducting the BaBar experiment at the Stanford Linear Accelerator Center (SLAC) that a dramatic difference exists between the behavior of matter and antimatter. Students and educators can learn about B mesons and anti-B mesons and...
