The Wave Hunters

Does the universe wobble? Following the theoretical prediction of Albert Einstein, researchers are trying to measure gravitational waves. They occur as a result of tiny distortions in spatial geometry. With their research, the wave hunters hope to expand our understanding of space and time. With their experiments, the physicists from Hanover are working at the quantum limit. The problem: the measurements require extremely powerful and precise technologies in order to keep the gravitational waves from disappearing into the background noise of the light particles. To meet this challenge, a new technology is being used: squeezed light. Will they be successful in directly verifying gravitational waves for the first time?
