PX43615 General Relativity
Introductory description
Einstein's general theory of relativity (GR) is the basis for our understanding of black holes and the Universe on its largest scales. In GR the Newtonian concept of a gravitational force is abolished, to be replaced by a new notion, that of the curvature of spacetime. This leads in turn to predictions of phenomena such as the bending of light and gravitational time dilation that are well tested, and others, such as gravitational waves, which have only recently been directly detected.
The module starts with a recap of Special Relativity, emphasizing its geometrical significance. The formalism of curved coordinate systems is then developed. Einstein's equivalence principle is used to link the two to arrive at the field equations of GR. The remainder of the module looks at the application of general relativity to stellar collapse, neutron stars and blackholes, gravitational waves, including their detection, and finally to cosmology where the origin of the "cosmological constant"  nowadays called "dark energy"  becomes apparent.
Module aims
To present the theory of General Relativity and its applications in modern astrophysics, and to give an understanding of blackholes
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
The geometry of spacetime and the invariant “interval” in special relativity; geodesics and equations of motion applied to circular orbits within the Schwarzschild metric; 4vector formulation of special relativity; metric of special relativity; the equivalence principle and local inertial frames; motivation for considering curved spacetime; vectors and tensors in curved coordinate systems; geodesic motion revisited; motion in almostflat spacetime: the Newtonian limit; the curvature and stressenergy tensors; how the metric is determined: Einstein's field equations; Schwarzschild metric; observable consequences; blackholes; stability of orbits; extraction of energy; gravitational radiation and its detection; cosmology: the RobertsonWalker metric
Learning outcomes
By the end of the module, students should be able to:
 Explain the metric nature of special and general relativity, how the metric determines the motion of particles
 Undertake some calculations involving the Schwarzschild metric
 Describe the key features of blackholes
 Demonstrate knowledge of current attempts to detect gravitational waves

Interdisciplinary
The theory of General Relativity, like quantum theory, has been the result of collaboration between people working in physics and in mathematics with insights flowing in both directions. At its core is a simple hypothesis about observations (the equivalence principle), which leads to a theory of gravity based on the differential geometry of curved spaces. This module covers both the necessary mathematics and computes some of the consequences for the physical Universe.
