Following the first direct detection of GWs by the LIGO Scientific Collaboration and Virgo Collaboration, and the success of the LISA Pathfinder mission, we can firmly claim that we are heading into an era of discoveries with the opening of a new window on the universe: the GW window. Black holes are primary sources both from ground and space based experiments. There is a fil rouge connecting stellar black holes and supermassive black holes that I will describe in this talk. Gravitational waves will provide the perhaps most promising pathway to determine the black hole mass function in the entire spectrum, and over a wide large range of redshifts, from cosmic dawn to the present. The impact on astrophysics and on fundamental physics of such discoveries is discussed: are the black holes of the Universe Kerr?
