WebEquipped with these approximations, the reduced-order field equations are easily integrated and the first-order (in ℏ) corrections to the metric are obtained. We also compute the corrections to the black hole event horizon, surface gravity, and minimum temperature as well as corrections to the photon sphere and quadratic curvature invariants. WebAug 3, 2012 · This seems, at first, to contradict the whole idea of a black hole. Let B denote a macroscopic black hole—perhaps the one in the center of the Milky Way—and let A be some other macroscopic body, perhaps a rock or an astronaut. Finally, let B* be a heavier black hole that can be made by combining A and B. General relativity tells us that the …
