This book reviews a number of important developments in the application of inhomogeneous solutions of Einstein's field equations to cosmology. Models is becoming an essential tool for analyzing and understanding them. Step 3) Hubble shows the universe is expanding in 1929, . Cornelius Hoenselaers, Dietrich Kramer, Eduard Herlt, Hans Stephani, Malcolm MacCallum. It is an exact solution to EFE (Einstein's Field Equations). He discovered exact solutions to Einstein's field equations for the gravitational field around one cosmic string (in 1985) and two moving cosmic strings (in 1991). The conclusion is straightforward: Smilga's choice select a class of common solutions between Yang-Mills equations and a quartic scalar field. This is an exact solution of Einstein equations that depends solely on time. Exact Solutions of Einstein's Field Equations. Exact.Solutions.of.Einstein.s.Field. Now, the little issue with that is it is an unstable solution, unless you happen to strike the exact equilibrium, you would expect the system to evolve either "universe gets smaller" or "universe gets bigger". Friedmann and Lemaitre independently solved Einstein's field equations to show that the universe is either expanding, contracting, or an unstable steady state. €We find an exact quantized expression of the Schwarzschild solution to Einstein's field equations utilizing spherical Planck units in a generalized holographic approach. It describes a simply connected, homogeneous, isotropic expanding or contracting universe.
