Interview with Reinhard Genzel, director at the Max Planck Institute for Extraterrestrial Physics (MPE) and architect of the 30-year programme that led to the discovery of the Schwarzschild precession around the black hole at the heart of our Milky Way. Genzel describes the general relativity effect observed by his team and how it can be used to study the galactic gravity trap.Reinhard Genzel receives the Nobel Prize for Physics 2020 Digital Story: Reinhard Genzel
