The Particle Physics Group, Gravitational Wave Group and Astronomy Society present an evening of discovery in the School of Physics and Astronomy. We encourage adults, families and children of all ages to learn more about the physics of the universe we live in via our hands on activities, lectures and demonstrations. Find out how we use kilometre size facilities like LIGO and the LHC to discover the invisible forces which influence everything from the smallest subatomic particle to the structure of galaxies.
