General Relativity is a theoretical framework that describes how gravity arises from the curvature of spacetime caused by mass and energy. It extends special relativity, which deals with objects moving at constant speeds, to include acceleration and gravity, unifying them into a single framework. It provides a geometric interpretation for gravity, where masses move along the curves of spacetime, rather than being attracted through empty space. This theory has significant implications in cosmology and astrophysics, providing the foundation for understanding black holes, neutron stars, and the large-scale structure and evolution of the universe. As part of relativity in Science and Mathematics, General Relativity explores the intimate relationship between geometry and physics, bringing together the realms of measurement, motion, and force.
