米斯纳已经证明，在克尔黑洞对无质量波场的散射中，某些模式会以黑洞的转动能量为代价被放大。我们在这里表明，这种效应的存在可以从基于霍金定理的简单考虑中推导出来，即黑洞的面积永远不会减小;没有必要详细检查波动方程。这种新的方法也揭示了存在类似的米斯纳过程中，一个带电的波场被放大后，被散射的带电黑洞，从而提取电荷和库仑能量从孔。这种方法的额外副产品是克尔黑洞和附近自旋粒子之间存在自旋-自旋力的简洁证明，重子和轻子数守恒定律超越的例子，以及霍金定理量子违反的例子。这种违反的起源进行了讨论。
Misner has shown that in the scattering of massless wave fields by a Kerr black hole, certain modes are amplified at the expense of the rotational energy of the hole. We show here that the existence of this effect can be deduced from simple considerations based on Hawking's theorem that the area of a black hole can never decrease; no detailed examination of the wave equations is necessary. This new approach also reveals the existence of an analog of the Misner process in which a charged wave field is amplified upon being scattered by a charged black hole with consequent extraction of charge and Coulomb energy from the hole. Additional byproducts of this approach are a concise demonstration of the existence of a spin-spin force between a Kerr black hole and a nearby spinning particle, examples of the transcendence of the conservation laws for baryon and lepton numbers, and an example of a quantum violation of Hawking's theorem. The origin of this violation is discussed.
