Without elementary particles, there would be no X-ray machines, no Internet, and no electricity. Some elementary particles penetrate matter without destroying it, and are therefore particularly interesting for applications in science and medicine. But do we already know all the elementary particles? This question is a concern for researchers who are busy deciphering the protein structure of viruses or showing us cavities in the Egyptian pyramids. If the German Electron Synchrotron (DESY) research centre succeeds in sending light particles through matter, it could prove the existence of a previously unknown elementary particle. This is important because we still don't know what about 85% of the matter in the universe is made of. We call it dark matter. If we understand what it is made of, we will not only know what holds our planet together at its core, but also the universe. Professor Christian Schwanenberger and other leading scientists take us to DESY in Hamburg and the European Organization for Nuclear Research (CERN) in Geneva to visit tunnels, laboratories and research facilities. In the process, they tell us about the history of particle physics and tell us about brilliant minds such as Wilhelm Conrad Röntgen and Peter Higgs. #dwdocumentary #documentary #bigbang ـــــ DW Documentary brings you information beyond the headlines.
