Seeing the invisible: Observing the dark side of the universe
Dr Sarah Bridle (UCL Physics & Astronomy)
Dr Bridle will describe in pictures âgravitational lensingâ, the bending of light by gravity, which is predicted by Einsteinâs General Relativity. The mysterious dark components that constitute most of the universe do not emit or absorb light, but they do exert a gravitational attraction, and gravitational lensing is one of the most promising methods for finding out more about them. Dr Bridle will review the current observations and upcoming surveys.
