Einstein's Lens

Gravitational lensing provided the first proof of Einstein's new theory of gravity and handed astronomers an incredible tool in their quest to uncover the deepest mysteries of our universe. This presentation explains how gravity behaves like a lens, distorting and magnifying our view of the cosmos, and tells the story of the scientific discoveries confirming this idea and how astronomers currently use lensing to explore the early universe, the nature of dark matter, and extra-solar planets.
