 Schwarzschild metric -
The Schwarzschild metric is a solution to vacuum field equations, meaning that it is only valid outside the gravitating body.
The Schwarzschild solution appears to have singularities at r = 0 and r=r_s; some of the metric components blow up at these radii.
If one asks that the solution be valid for all r one runs into a true physical singularity, or gravitational singularity, at the origin.
