Webthe black hole starts from the Hawking temperature and nally vanishes when taking into account the quantum backreaction. In the end, the black hole temperature approaches zero, which implies that the radiation temperature should also be zero in the quasi-equilibrium assumption. Now, one might wonder how the black hole temperature could … WebOct 29, 2024 · R S ( M) = 2 G M c 2, where G is the gravitational constant and c is the speed of light. It is okay if you do not follow the details of the equation; the basic point is that if you put an amount of mass M or larger in a sphere of radius smaller than RS ( M ), then voila—it will become a black hole.

The metric describes a frame that is accelerating to keep from falling into the black hole. The local acceleration, α = 1 ρ, diverges as ρ → 0 . The horizon is not a special boundary, and objects can fall in. So the local observer should feel accelerated in ordinary Minkowski space by the principle of equivalence. See more Hawking radiation is theoretical black body radiation that is theorized to be released outside a black hole's event horizon because of relativistic quantum effects. It is named after the physicist Stephen Hawking, … See more Hawking radiation is dependent on the Unruh effect and the equivalence principle applied to black-hole horizons.
