Query: Smooth Singularities Exposed: Chimeras of the Differential Spacetime
  Manifold   The smooth gravitational singularities of the differential spacetime manifold
based General Relativity (GR) are viewed from the perspective of the background
manifold independent and, in extenso, Calculus-free Abstract Differential
Geometry (ADG). In particular, the inner Schwarzschild singularity is being
`resolved' ADG-theoretically in two different ways. A plethora of important
mathematical, physical and philosophical issues in current classical and
quantum gravity research are addressed and tackled.
