Abstract
Because of the very definition of black holes --- no light escapes them and falling objects get infinitely faint when approaching --- it is impossible to ever prove that they exist. However, electromagnetic and gravitational-wave observatories have now `seen' black holes. Datasets from these observations, released in 2019 and late 2018, give important hints about the environment, origin and growth of black holes.
