In science fiction stories it is either the inexhaustible energy source of the future or a superweapon of galactic magnitude: antimatter. In fact, antimatter can neither be found naturally in any abundance on Earth nor in space, is extremely complex to produce and thus difficult to study. In order to track down the origin of matter and antimatter in the universe, scientists are measuring the power of the electrical dipole moment of neutrons, which represents a measure for the different physical properties of matter and antimatter.
