Seeing the invisible: Observing the dark side of the universe
Tuesday 27 October
(To celebrate the 400th Anniversary of the telescope and World Space Week (4-10 October)) - part of the UCL Lunch Hour Lectures.
Dr Sarah Bridle (UCL Physics & Astronomy) described in pictures ‘gravitational lensing’, the bending
of light by gravity, which is predicted by Einstein’s 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 reviewed the
current observations and upcoming surveys.
