What are we learning from the eclipse?

Einstein's Light-Bending Concept

Einstein predicted that light should be bent by gravity, and Sir Arthur Eddington led an expedition to photograph the 1919 total eclipse of the sun. The photographs he took revealed stars whose light had passed near the sun, and their positions showed that the light had been bent exactly as Einstein had predicted. This video explains Einstein’'s light-bending concept using nothing more than a wine glass and an LED light.
