We discuss new and fascinating observations of gravitational waves with three of our favourite cosmologists.

On the sixth day of advent we find out why gravitational waves are so important in revealing the secrets of the Universe.

On the fifth day of advent we learn about the heroic effort that led to the detection of gravitational waves and the excitement of their discovery.

On the fourth day of advent, we remember one of our most exciting cosmological events, watching the announcement of the detection of gravitational waves in 2016.

Straddling the boundary between pure and applied mathematics.

This year's Nobel Prize in Physics has gone to Rainer Weiss, Barry Barish and Kip Thorne for their role in the detection of gravitational waves.

Find out what gravitational waves will tell us about the Universe: from understanding its birth to figuring out whether black holes have hairs.
