For over 20 years physicists have been trying to catch the first gravity wave without success until February 2016 when the Laser Interferometer Gravitational-Wave Observatory (LIGO) announced that they had recorded the ripples from two black holes colliding.
The Dr Pete Edwards talk will focus on this historic discovery, the technology behind gravitational wave detectors and explore the dawn of multi-messenger astrophysics.

Gravitational waves offer a new way to uncover the universe.
General relativity suggested their existence, but even Einstein wasn’t sure about them. It wasn’t until the 1970s that there was evidence of their existence, but it took 40 years to be able to detect them.
Now we can detect these ripples in space time, what do they tell us about black holes, neutron stars and the fundamental nature of the universe?
