Course Overview:
This course will further extend our understanding of general relativity. We begin by studying linearised gravity and gravitational waves before studying stellar collapse of cold stars and the inevitability of the formation of black holes.
We discuss singularities, the causal structure of spacetime using Penrose diagrams and give a formal definition of a black hole. We then study larger classes of black hole solutions including the Kerr--Newman and Reissner--Nordstrom solutions and study their causal properties before studying the laws of black hole thermodynamics.

Learning Outcomes:
By the end of the course, students will be able to
- Understand linearised gravity and gravitational waves.
- Understand the gravitational collapse of a star to form a black hole.
- Understand the causal properties of various different spacetimes by constructing Penrose diagrams.
- Explain the concept of a black hole and identify its mass, angular momentum and electric and magnetic charges.
- Understand the laws of black hole thermodynamics and the need for a theory of quantum gravity.
