Without elementary particles, there would be no X-ray machines, no Internet, no electricity. Since some elementary particles can penetrate matter without destroying it, they are a boon for scientific and medical applications. Because we don’t already know all the elementary particles? Researchers have taken up the task of investigating this area. They are deciphering the protein structure of viruses or revealing cavities in the Egyptian pyramids. If the German Synchrotron Research Center succeeds in sending light particles through matter, it could be evidence of a new, previously unknown elementary particle. This is important because we still don’t know what about 85 percent of the matter in the universe is made of. It is called dark matter. If we understand what the universe is made of, we will not only know what holds the world together on the inside, but also on the outside. Professor Christian Schwannenberger and other leading scientists will take us to the German Synchrotron Research Center in Hamburg, to the tunnels of CERN in Geneva, and to laboratories and field research. We will also learn about the story of particle physics from influential researchers such as Wilhelm Conrad Röntgen and Peter Higgs. ـــــ #Documentary #DW #DarkMatter #Physics ـــــ Invitation to dialogue at DW: https://p.dw.com/p/OYIo More documentaries are available on our websites in English: http://www.dw.com/ar/tv/docfilm/s-3610 / dwdocumentary / dw.stories
