Spacetime and Geometry

The book provides a clear introduction to general relativity, focusing on its foundational concepts and mathematical framework. Key applications explored include black holes, gravitational waves, and cosmology. Readers will gain insights into the Einstein equation and the geodesic equation, learning how spacetime curves and how matter interacts with it. The text also covers the generation and detection of gravitational waves and offers a modern perspective on the universe's expansion. Additionally, it includes an introduction to quantum field theory in curved spacetime, preparing students for advanced research in gravitational physics.
