A Study on the Theoretical Framework, Cutting-Edge Advances, and Scientific Impact of Relativity

Abstract

As one of the most profound theoretical systems in 20th-century physics, relativity revolutionized humanity’s understanding of spacetime, gravity, and the fundamental laws of nature. While its foundational principles—special relativity (SR) and general relativity (GR)—have stood the test of time, recent decades have witnessed remarkable advances in theoretical and experimental extensions. This paper reviews the core framework of relativity, emphasizes cutting-edge progress in gravitational wave astronomy, black hole physics, quantum gravity, and cosmological applications, and explores how these developments continue to reshape modern science and technology.
