Course purpose

The purpose of the course is to introduce General Relativity to the student and then apply this theory to describe:

1) the dynamics of particles and electromagnetic fields in the presence of general gravitational fields;

2) gravitational waves

3) the evolution of our Universe

4) black holes

Learning objectives and syllabus

During  the course the student is expected to acquire a basic understanding of the concepts and principles of General Relativity and a working knowledge of the mathematics used in this field. Specifically, the student should be able to discuss and explain the physical ideas behind the phenomena described by Einstein's theory of gravity, General Relativity, and in a skilful way use the relevant mathematical methods in problem-solving.

Learning objectives:

- The Principle of Relativity: the role of coordinate transformations in Physics

- The Principle of Equivalence and why General Relativity is a theory of gravity

- The mathematical methods used in General Relativity, including tensor analysis

- Einstein's equations: how to derive and solve them

- Why the presence of matter and energy affects the geometry of spacetime

- The basic tests of General Relativity, such as the bending of light in a gravitational field

- Gravitational waves

- The role of General Relativity in Cosmology: maximally symmetric spaces

- The Cosmological Principle and its implications

- The standard Model of Cosmology

- Black holes

 

Examination form

The examination is divided into two mandatory parts (with grading weights given below):

1) Home problems (weight: 40%) to be published on Canvas. Each set of problems assigns 40 points. 20 points in each set are required to be admitted to the oral exam.                                                      

2) Oral exam (weight: 60%). It consists in a 10 minute-long blackboard presentation on a topic chosen by the student among the ones addressed in the course followed by 40 minutes of questions on the concepts and equations discussed in the course. The student will be asked to re-derive some of these equations on the blackboard.
