The goal of Antimatter Matters is to collect the right elementary particles to assemble an atom. You have to avoid hazards like quantum entanglement, antimatter collisions, cosmic radiation and solar flares messing up your instruments—not to mention the actions of other player-scientists pursuing the same goal. Along the way, you'll learn something about the strange and wonderful world of quantum physics: how a handful of elementary particles interact in various ways to form the nuclei and atoms that make up ourselves and everything we experience in the world around us.
