Relativity and Gravitation study the nature of space, time, and gravity under relativistic principles. This field replaces classical notions of absolute space and time with a unified spacetime framework. Gravitation is interpreted as the curvature of spacetime caused by mass and energy. Relativity explains phenomena such as time dilation, length contraction, and gravitational redshift. It is essential for understanding astrophysical systems and cosmology. Relativity and gravitation describe black holes, gravitational waves, and cosmic expansion. Mathematical modeling uses geometry and tensor calculus. This field has transformed fundamental understanding of the universe and continues to guide research in astrophysics and cosmology.
