Abstract: In 2015 the LIGO detector observed, for the first time, a gravitational wave passing through the Earth produced by the collision of two black holes. Such an event was a milestone for astrophysics and it provided a spectacular confirmation of Albert Einstein’s general theory of relativity. Since then, 90 gravitational waves have been observed by the LIGO and Virgo experiments. In this lecture, I will discuss how those novel astronomical messengers are already unveiling distinctive and puzzling properties of the most peculiar astrophysical objects in the universe: black holes and neutron stars. In the next decades, those sounds of silent will provide us with the unique and wondrous opportunity of peering back to the time the first stars formed, and eventually to the very earliest moments of the universe, shedding light on its origin.
