This paper is a mathematical treatise and historical perspective of Karl Schwarzschild’s original 1916 solution and description of a Non-Euclidean Spherically Symmetric Metric equation. In the modern literature of the Schwarzschild Metric equation, it is described as predicting an output of a “Coordinate Singularity” anomaly located at the surface of the Black Hole Event Horizon. However, in Schwarzschild’s original 1916 metric solution there is not a “Coordinate Singularity” located at the Black Hole Event Horizon, but there is an actual quantitative value for space and time, that is predicted there. This paper and work compares the Schwarzschild Spherically Symmetric Metric equation original 1916 results with the results predicted by the modern literature on the Schwarzschild Metric. This work also describes conceptually the physics behind the Gaussian Distance Curvature and Reduction Density equation that Schwarzschild used to eliminate and avoid a “Coordinate Singularity”. This work reveals that Schwarzschild’s original 1916 solution, predicts that the Inertial Mass Volume Density, Escape Velocity, and gravitational field acceleration is reduced at all points in the inhomogeneous gradient gravitational field. This reduced Schwarzschild Gaussian density also reduces the gravitational tangential velocity, and acceleration in the inhomogeneous gradient gravitational field.
