Surrey University – Gravitation Waves

Gravitational Waves have finally been discovered! The LIGO collaboration (Laser Interferometer Gravitational-Wave Observatory) announced the first ever detection of gravitational waves, coming from the violent collision of two black holes. It is no exaggeration to describe this as one of the most significant scientific discoveries of the century. Not only does it demonstrate that gravitational waves exist, it provides the first probe of gravity in the strong field regime; further proof that black holes exist; and the first evidence for binary black holes and black hole mergers.

To celebrate this tremendous achievement, we will give a series of short talks explaining what gravitational waves are; why they are so exciting; and the implications of these results for astronomy and physics as a whole. Our speakers include two astronomers Prof Justin Read and Dr Alessia Gualandris, a photonics specialist Dr Steve Clowes, who will give a simple laser demonstration of how LIGO works,  and a nuclear physicist Dr Arnau Rios Huguet.
