The discovery of the massive black hole in the center of the Milky Way was honored in 2020 with the Nobel prize. Yet, our research nowadays goes way beyond the discovery. We don’t ask anymore whether the black hole exists, rather we use it to conduct physics experiments in the sky. It is perfect laboratory, located at a mere 26.000 light years in our cosmic backyard. This allows for breath-taking precision measurements that not only test Einstein’s theory of general relativity, but that even reveal that beyond the black hole, not much more matter can hide in the Milky Way center.
