In the last part of the semester, we will write Einstein’s equation for the entire universe. However, much less is known about realistic material sources for these vacuum solutions, and there does not seem to exist a single exact solution of Einstein's equations com- One can also discover new solutions of the Einstein field equations via the method of orthonormal frames as pioneered by Ellis and MacCallum. /FirstChar 33 << A paperback edition of a classic text, this book gives a unique survey of the known solutions of Einstein's field equations for vacuum, Einstein-Maxwell, pure radiation and perfect fluid sources.
