The spacetime geometry outside a black hole may be transformable through the event horizon as the black hole internal geometry, and conversely.(adsbygoogle = window.adsbygoogle || []).push({});

Consider Hawking radiation with respect to black hole entropy. While one quantum escapes to universal infinity, the other approaches the corresponding infinitesimal singularity. Entropy is alwaysconserved between opposite horizons, thermally isolated, singularity and Hubble area. The event horizon represents their mirror symmetry, at which the universal spacetime inverts to actualize the black hole spacetime and reciprocate the relative surface curvature. The hole itself, surrounded by the entropic cosmos, is thus anentropic in character. The relation that horizon surface area is proportional to black hole entropy holds for both perspectives,eitheroutside or within the hole.
