When the Schwarzschild Metric is applied to the invariant components of the expanded Metric Tensor, the space-time interval, ds2, is given as: *attached screenshot. Determine the space-time interval, in the plane of rotation, and a non-orbiting reference frame, for a Schwarzschild Black Hole of 50 Solar Masses (m = 9.95 x 1031) when the radius, r, equals
