"The general theory of relativity must be wrong at some point." - The world-renowned galaxy researcher Reinhard Genzel is convinced of this.
Using specially developed, extremely accurate infrared measuring instruments for telescopes, he and his team were able to detect a black hole - "Sagittarius A," 27,000 light-years away - in the middle of our Milky Way for the first time. For this, Genzel received the Nobel Prize in Physics in 2020.
The existence of such black holes had been formulated within the framework of Einstein's general theory of relativity, but according to Genzel, this basic theory of physics is only a transitional theory. In the future, he wants to challenge it with even more precise measurements. What does he think will replace general relativity? What are the next steps in galaxy research? And where is national and international research in astrophysics currently heading?
Prof. Dr. Reinhard Genzel is Director at the Max Planck Institute for Extraterrestrial Physics in Garching and teaches at the Ludwig Maximilian University of Munich and the University of California.
