JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]A custom-built laser has cooled antimatter to near absolute zero. The work, carried out by researchers with the CERN-based ALPHA collaboration, holds significant implications for the study of antimatter and its properties, and of foundational theories of the universe. Antimatter is nearly identical to matter in terms of its behavior and characteristics, but it possesses the opposite charge. When matter and antimatter come into contact, they annihilate one another. Experimentation remains difficult for this reason. The movement of an antihydrogen atom in the ALPHA magnetic trap,...Read full articleRelated content from Photonics MediaArticlesTimekeeping Breakthrough Offers to Rewrite Nature’s ConstantsResearchers have long dreamed of the secrets they could unlock by raising the energy state of an atom’s nucleus using a laser.
