Criticism of the clarification on Schwarzschild solution by Christian Corda (3)

This writer claims that the original Schwarzschild solution is equivalent to the standard Schwarzschild solution and that the difference between them is merely a matter of different coordinate systems. This, of course, is contrary to reality because Schwarz's original solution is based on a singularity point at the center of mass, while the standard solution results in a singularity point at a certain distance from the center. The writer has tried to evade this clear truth with arguments that contain a lot of effort and affectation that do not get rid of the contradiction but move it to another field. He claims, for example, that the point of origin of the coordinate system in the original solution is not a point, and that the relationship between the radius and the circumference of the circle in this system It is not the simple, well-known relationship...etc. It is known that changing the reference system cannot turn the point into a sphere, cannot change the relationship between the radius and the circumference of the circle, and cannot change the geometry of the space. Changing coordinate systems does not do any of this, but it only changes the analysis of quantities into their dimensions. For example, the distance between two points remains in its shape and length regardless of the reference system with which we look at it, but it only differs from one system to another in the way it is analyzed into its three dimensions.
