General Relativity and Gravitational Waves: Exact Solutions of Einstein's Field Equations
Lingaraju
Abstract:
This study delves into the exact solutions of Einstein's Field Equations (EFE) within the framework of
General Relativity, focusing on the Schwarzschild, Kerr, and Friedmann-Lemaître-Robertson-Walker
(FLRW) metrics. These solutions are pivotal in understanding a range of gravitational phenomena, from
the properties of black holes to the dynamics of the expanding universe. The role of gravitational
waves, as predicted by General Relativity, is explored, emphasizing their significance in testing the
theory in the strong-field regime and providing insights into the universe's most extreme environments.
The study also discusses the challenges inherent in solving the EFE, the importance of numerical
relativity, and the future of gravitational wave astronomy, particularly through the development of nextgeneration detectors and the integration of multi-messenger observations. The findings underscore the
continued relevance of Einstein's theory while highlighting the potential for new discoveries that could
extend our understanding of gravity and the cosmos
