Schwarzschild and Kerr Solutions of Einstein's Field Equation -- an introduction

摘要: Starting from Newton's gravitational theory, we give a general introduction into the spherically symmetric solution of Einstein's vacuum field equation, Schwarzschild(–Droste) solution, and one specific stationary axially Kerr solution. The Schwarzschild is unique its metric can be interpreted as exterior mass. only if multipole moments mass angular momentum take on prescribed values. Its suitably rotating distribution. Both solutions describe objects exhibiting an event horizon, frontier no return. corresponding notion black hole explained to some extent. Eventually, present generalizations
