Dark matter. Unlike normal matter, dark matter does not interact with the electromagnetic force. This means it does not absorb, reflect or emit light, making it extremely hard to spot. In fact, researchers have been able to infer the existence of dark matter only from the gravitational effect it seems to have on visible matter. Dunkle Materie First evidence for Dark Matter has been obtained from the kinematics of galaxies as revealed by ground-based optical observations in the first third of the 20th century. Both in the context of stars within galaxies as well as in the context of galaxies within galaxy clusters, the kinematics of individual objects exceeded the Zwicky named this matter "Dunkle Materie" or, literally translated, "Dark Matter". Zwicky's work on dark matter did not have a very large scientific impact until 1970 when Vera Rubin studied the rotational curve of the Andromeda galaxy, "Rotation of the Andromeda Nebula from a Spectroscopic Survey of Emission Regions", Astrophys.J Dunkle Materie und Dunkle Energie haben lediglich gemeinsam, dass derzeit völlig unbekannt ist, um was es sich dabei überhaupt handelt. Sie beschreiben völlig unterschiedliche Phänomene. The Bullet Cluster provided the first strong evidence for the existence of dark matter. Dark matter, which makes up about 85% of the mass in the Universe, is more than simply dark. True, it can't shine by its own light, like hot coals, or even reflect light, like clouds or water. Neither electricity nor magnetism affect it. Dunkle Materie. Rund achtzig Prozent der Materie im Universum bestehen offenbar aus einem unsichtbaren und bislang unbekannten Stoff. Physikerinnen und Physikern mangelt es nicht an Ideen, um was es sich dabei handeln könnte - doch bisher tappen sie noch im sprichwörtlichen Dunkeln.
