The Role of Symmetry in Modern Physics: From Noether's Theorem to Gauge Symmetry
N. Kumar Swamy, Ram Krishna
Abstract
Symmetry plays a foundational role in modern physics, providing deep insights into the fundamental principles governing the universe. Noether's theorem establishes a profound link between symmetries and conservation laws, while gauge symmetry is central to the formulation of field theories describing fundamental interactions. This paper explores the relationship between these concepts, highlighting their significance in theoretical physics. We discuss the connection between symmetries and conservation laws, the role of gauge symmetry in field theories, and provide examples illustrating these concepts. The historical development of gauge theory and its applications in modern physics are also examined. This study underscores the profound implications of symmetry in understanding the laws of nature and highlights open questions for future research.
