"Black holes were first discovered as purely mathematical solutions of Einstein's field equations. This solution, the Schwarzschild black hole, is a nonlinear solution of the Einstein equations of General Relativity: It contains no matter, and exists forever in an asymptotically flar space-time."

(Dictionary of Geophysics, Astrophysics, and Astronomy)
