Greg Pawloski is an expert on antimatter. As such he works on one of the great unsolved mysteries of physics: what is the cause of the great asymmetry in matter and antimatter? Physicists have long theorized that there are antiparticles for every particle in the Universe and that these annihilate one another in pairs. Yet, if there were an equal number of anti-matter particles, there would be no matter in the Universe.
