8.962 General Relativity (Spring 2020, MIT OCW): Lecture 12

8.962 General Relativity

8.962 General Relativity (Spring 2020, MIT OCW). Instructor: Prof. Scott Hughes. 8.962 is MIT's graduate course in general relativity, which covers the basic principles of Einstein's general theory of relativity, differential geometry, experimental tests of general relativity, black holes, and cosmology.

Lecture 12 - The Einstein Field Equation

The Einstein curvature tensor, a variation on the Ricci curvature, defined so that it has vanishing covariant divergence. Using this tensor, we at last build a field theory for spacetime, motivating the Einstein field equation by arguing how to generalize a gravitational field equation to relativity.
