Sumario:<HTML>Currently, Hänsch is also working with the ATRAP Collaboration at CERN, which is studying hydrogen and antihydrogen atoms. If it were possible to measure precisely up to 14 or 15 digits, then it might be possible to see whether matter and antimatter are the same or if they differ in some unexpected way. This could explain why there is more matter than antimatter in the universe. To explore these questions, researchers have to look where no-one has ever looked before, and for that reason, Hänsch has a passion for precision.
