Using carefully tuned lasers, scientists from the University of Tokyo successfully cooled and slowed down samples of Positronium. Their study is expected to help explore exotic forms of matter to unlock secrets of antimatter.
Associate Professor Kosuke Yoshioka from the Photon Science Center said, “We have successfully slowed and cooled down exotic atoms of Positronium, which is 50% antimatter. This means that, for the first time, it can be explored in previously impossible ways, which will necessarily include a deeper study of antimatter.”
