The Kruskal-Szekeres "coordinates" are said to "extend" the so-called "Schwarzschild solution", to remove an alleged "coordinate singularity" at the event horizon of a black hole at r = 2m, leaving an infinitely dense point-mass singularity at "the origin" r = 0. However, the assumption that the point at the centre of spherical symmetry of the "Schwarzschild solution" is at "the origin" r = 0 is erroneous, and so the Kruskal-Szekeres "extension" is invalid; demonstrated herein by simple counter-examples.
