Public talk (in German) “Einsteins Gravitationswellen – Wir können das dunkle Universum hören!”

For thousands of years we have been looking at the Universe with our eyes. But more than 99% of the Universe are dark and will never be observed with electromagnetic waves. Since the 14th of September 2015 everything has changed: gravitational waves were discovered! We now have a new sense for the Universe and can finally hear its dark side. Since then we have listened to several mergers of binary black holes and that of a double neutron star. And nobody knows which other dark secrets wait for us out there.
