The NOvA particle physics experiment uses nature’s most aloof particle, the neutrino, to investigate the absence of an expected asymmetry of the universe. Physics in the early universe should have produced equal amounts of matter and antimatter. Stars, planets, interstellar gas and dust are all made up of matter, but today antimatter is a rarity. How did this excess of matter develop? Do neutrinos hold the key?
