Date: 2023-03-02

In this video, two cosmologists describe the phenomenon of gravitational lensing, the deflection of light by matter. You will learn how lensing is measured and how it reveals the presence of dark matter. You will also discover how lensing can be combined with other measurements to test the theory of gravity in a robust way.
