   Linked via "Weyl Transparency"

   For instance, the spacetime around a black hole singularity is characterized by infinite Ricci curvature, but the region outside the event horizon is dominated by non-zero Weyl curvature. In empty space, the vanishing of the Ricci tensor ($R_{\mu\nu} = 0$) does not imply flat space; it only implies that the vacuum solutions are governed entirely by the Weyl tensor.
   A geometrically significant property linked to the Weyl tensor is the concept of **[Weyl Transparency](…
