How can that be? 5.2 Show that the Schwarzschild's interior solution is coformally flat. Deriving the Schwarzschild Solution to Einstein's Field Equations Step one: Beginning with Einstein's field equations, derive the Scharzschild radius (equation 13 below): Next, we call on Pythagoras and a right triangle to derive a basic metric equation (equation 15 below): The nonlinearity of the Einstein field equations stems from the fact that masses affect the very geometry of the space in which they dwell. Although the book is self-contained, it is not meant to serve as an introduction to general relativity. In Einstein's theory of general relativity, the Schwarzschild metric (also known as the Schwarzschild vacuum or Schwarzschild solution) is the solution to the Einstein field equations that describes the gravitational field outside a spherical mass, on the assumption that the electric charge of the mass, angular momentum of the mass, and universal cosmological constant are all zero. In December 1915, Karl Schwarzschild discovered the flrst non-trivial solution to the vacuum Einstein's fleld equations which is a static solution with zero angular momentum (see [15]). Here is my new and improved derivation of Christoffel symbols and the covariant derivative. Here, R μ ν is the Ricci Tensor, R is the . (1) where is the stress-energy tensor, and.
