Space itself is wobbly. We exist on a choppy sea, its surface roiled by disturbances caused by the movements of black holes hundreds of millions of light-years away. The detection of these 'gravitational waves' by observatories such as LIGO is a story of scientific persistence and precision engineering, resulting in a completely new way of looking at the cosmos. The lecture will highlight the latest results from LIGO's observing run, discuss the nature of black holes - the most mysterious of astronomical objects - and explain how the gold in your jewellery was made.

This lecture was recorded by Chris Lintott on 4th December 2024 at Conway Hall, London

Chris is Gresham Professor of Astronomy.

He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.
