Researchers based at the Stanford Linear Accelerator Center announced that they had delineated the mechanism by which the universe favors matter instead of empty space. The team of scientists had used Stanford University’s 1,200-ton (1,090-tonne or 1.1 million-kilogram) particle detector to study the process of charge-party violation (CP violation) ~ the interactions and relationships between matter and antimatter. Although scientists had long believed that matter and antimatter are distinctly different, obtaining proof of this had proved difficult. The new discovery provided significant support for the hypothesis, exciting the scientific community. As physicist Stewart Smith, spokesperson for the research group, explained: “After 37 years of searching for further examples of CP violation, physicists now know that there are at least two kinds of subatomic particles that exhibit this puzzling phenomenon, thought to be responsible for the great preponderance of matter in the universe.” (Kathy Sawyer, “New Insight into Reason Matter Exists; Studies Confirm Cosmic Mechanism,” Washington Post, 7 July 2001.)
