Seeing the invisible: Observing the dark side of the universe

lensing


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.
