  6. More about the Schwarzschild Geometry
    Schwarzschild metric

    Schwarzschild's geometry is described by the metric (in units where the speed of light is one, c = 1)
    ds2 = - ( 1 - rs / r ) dt2 + ( 1 - rs / r )-1 dr2 + r2 do2  .
    The quantity ds denotes the invariant spacetime interval, an absolute measure of the distance between two events in space and time, t is a `universal' time coordinate, r is the circumferential radius, defined so that the circumference of a sphere at radius r is 2 pi r, and do is an interval of spherical solid angle.
