Schwarzschild Metric

The Schwarzschild metric is a mathematical description of how spacetime is curved around a spherical, non-rotating object like a star or black hole. It explains how gravity affects the paths of objects and light near such an object. Essentially, it shows that mass distorts the fabric of space and time, creating a "well" that influences motion. This metric provides the foundation for understanding phenomena like black holes and gravitational lensing, where light bends around massive objects, and helps us understand the structure of spacetime in the presence of a spherical mass.
