How Does Gravity Affect Light?

The video explores the relationship between light and gravity, starting with historical predictions by John Mitchell and Henry Cavendish. It delves into Einstein's general theory of relativity, explaining concepts like gravitational redshift and the equivalence principle. The video also covers the deflection of light by gravity, using Huygens' principle and Einstein's calculations, which were verified by Eddington's observations during a solar eclipse.
