Introduction to String Theory, Lecture 5

String Theory Explained At the deepest levels of reality, the universe may not be composed of point-like particles but of unimaginably small, vibrating strings. This radical idea, known as string theory, proposes that all fundamental forces, including gravity, are unified in a single framework, potentially resolving the long-standing conflict between quantum mechanics and general relativity. These tiny strings oscillate in different patterns, much like musical notes on a violin, with each vibrat
