Two new accelerators, one at the Stanford Linear Accelerator Center (SLAC) in Palo Alto and another in Japan, have begun to yield results that could reveal exactly how the symmetry between matter and antimatter is broken.
San Francisco, CA -- The seemingly unremarkable fact that the universe is full of matter turns out to be something physicists can't quite account for. According to the big bang theory, equal amounts of matter and antimatter were created at the birth of the universe, but precious little antimatter is to be found in the universe today. Everything we see, from our bodies to our cars to the stars in distant galaxies, is made of matter. Cosmic rays and high-energy physics labs routinely create antimatter particles, but they soon interact with particles of matter and vanish in bursts of pure energy.
