Relativity Theory, proposed by Albert Einstein in the early 20th century, revolutionized our understanding of space, time, and gravity. The theory comprises two main parts: Special Relativity (1905) and General Relativity (1915). Special Relativity redefined the concepts of space and time, establishing the constancy of the speed of light and time dilation. General Relativity extended these principles to include gravity, interpreting it as the curvature of spacetime caused by mass and energy. This paper revisits Einstein's original concepts, explores recent advances, and discusses practical applications in astrophysics, cosmology, and quantum mechanics. Further, it highlights unresolved questions and the potential integration of relativity theory with quantum field theory.
