PHYC40120 General Relativity & Cosmology

Academic Year 2022/2023

This module introduces the theory of General Relativity, the relativistic formulation of gravity. Based on the equivalence principle, Einstein's field equations of General Relativity are discussed, including their mathematical foundation in differential geometry as needed. Linearised field equations are derived to describe weak gravitational fields, to make contact with Newton's theory of gravity, and to explain gravitational waves. The classical tests of General Relativity, in the solar system and beyond, are analysed, including current experiments to detect gravitational waves. Exact solutions of Einstein's field equations are presented, such as the static Schwarzschild solution and its black hole interpretation. Kinematics of a continuum matter distribution and isotropic cosmological models are discussed, with an emphasis on the past and future evolution of the universe.

This module is suitable for 4th-year undergraduate and graduate students, of all areas of physics and astronomy.
