Gravitational waves -- minuscule distortions in the fabric of spacetime -- were first predicted by Albert Einstein in 1916. They are created in cataclysmic events throughout the Universe. Using some of the most precise rulers ever built, gravitational waves were detected for the first time in 2015. This ground-breaking discovery has opened a new window onto the cosmos: Gravitational waves provide unique information about the most energetic astrophysical events, revealing insights into the nature of gravity, matter, space, and time. To date, many tens of gravitational waves originating from the collisions of black holes and neutron stars have been identified, giving us extraordinary new insights into the inner workings of our Universe. In this lecture, Dr Schmidt looks at the universe through Einstein's eyes: she will discuss the detection of gravitational waves as well as some of the most remarkable observations in recent years and their dramatic consequences for our understanding of the Universe.
