General Relativity and Astrophysics

General Relativity is Einstein's theory that describes how gravity works, explaining it as the curvature of space and time caused by mass. Instead of seeing gravity as a force pulling objects, it shows that massive objects like planets and stars warp the space around them, causing other objects to move along curved paths. Astrophysics uses this framework to study celestial bodies and phenomena, helping us understand the universe's structure, behavior, and evolution, from black holes to cosmic expansion. Together, they transform our understanding of space, time, and the cosmos itself.
