The ancients considered the Universe unchanging, and had a special name for the planets, which they regarded as “wanderers”. Any changes in the night sky were seen as portents of doom – and a reason to fear the Gods. The advent of modern astronomy means that we no longer fear changes in the night sky, indeed some of us make our living from them!
In this lecture I will tell you the story of the modern transient sky, where stars live and die in spectacular explosions and amazing instruments such as the LIGO and Virgo gravitational wave interferometers probe the darkest depths of the Universe. The discovery of gravitational waves was awarded the Nobel Prize in Physics this month and has the power to reveal a plethora of new science from the merger of black holes and other exotic stars. Presented on Friday 20 October 2017.
