The module provides an introduction to Einstein's theory of General Relativity. We lay the necessary grounds of differential geometry and tensor analysis with familiar concepts and non-relativistic mechanics before discussing the fundamental ideas behind Einstein’s theory. We show how Newton’s forces are being eliminated in favour of curvature of space-time, where matter and curvature are being related by Einstein’s gravitational field equations. We find Schwarzschild’s solution and discuss implications such as perihelion precession of planets, bending of light, gravitational redshift, time delay, black holes, and gravitational waves. Moreover, we show how General Relativity plays a role in current technology such as satellite navigation.
Aims & Objectives
