A century after the advent of the theory of general relativity by Albert Einstein, we are witnessing an outstanding year 2018 in black hole research. In three ground-breaking measurements with the MPE-led GRAVITY experiment, we could for the first time directly prove the gravitational redshift from a massive black hole, follow the orbital motion of accreting matter very close to the point of no return, and weigh the mass of black holes more than a billion light years away. With its unique image sharpness and sensitivity, GRAVITY is revolutionizing observational astronomy.
