General Theory of Relativity is one of the most profound theory of physics that forever changed our understanding of space and time. However, how to understand General Relativity. This seemingly daunting task challenges young minds and science lovers. In this video, you will learn about the spacetime geometry, the curvature, from Special Relativity how we move to curved spacetime, light cones, Minkowski metric, geodesic equation and various other concepts in General Theory of Relativity.
