Public talk (in German) “What gravitational waves reveal about the dark universe”

More than 100 years ago, Albert Einstein calculated that space and time can wobble and vibrate like jelly. These vibrations, known as gravitational waves, are created when stars explode or black holes collide. After researchers first observed these gravitational waves in September 2015, almost a hundred such observations have been made to date. They provide unique insights into the dark universe and its secrets.
