UCLA physicists offer a solution to the puzzle of the origin of matter in the universe
Most of the laws of nature treat particles and antiparticles equally, but stars and planets are made of particles, or matter, and not antiparticles, or antimatter. That asymmetry puzzled scientists for many years.
