论文摘要
弱重力猜想意味着具有电荷与质量比$ q/m \ geq 1 $的必要粒子，因此，极端带电的黑洞可以完全蒸发而不会留下危险的稳定稳定的极端残余，同时又不透露沿途露出裸奇异性。换句话说，这种不平等确保了电荷的发射速度比黑洞的质量快，这反过来既与此类当事方的重力相互作用均弱于电磁相一致。为了将这一论点扩展到非超级黑洞，我们从带有（$ M，Q $）的黑洞中解决了质量和充电（$ M，Q $）的问题。我们发现一个更通用的条件$ Q/M \ GEQ Q/M $，显然可以在极限限制下降低到弱重力猜想，但是它放松了完全蒸发非超级黑色孔的条件。这种情况还使我们能够将理论的粒子含量与黑洞状态的光谱直接相关。
The weak gravity conjecture implies the necessary existence of particles with charge-to-mass ratio $q/m \geq 1$ so that the extremal charged black hole can completely evaporate without leaving a dangerous stable extremal remnant while simultaneously not revealing a naked singularity along the way. In other words, this inequality ensures that the charge is emitted faster than the mass of a black hole, which is in turn coincidentally consistent with the fact that gravitational interaction for such parties is weaker than electromagnetic. To extend this argument to non-extremal black holes, we solve the problem of a charged shell of mass and charge ($m,q$) from a black hole with ($M,Q$). We find a more general condition $q/m \geq Q/M$, which obviously reduces to the weak gravity conjecture in the extremal limit, however it relaxes the condition for complete evaporation of non-extremal black holes. This condition also allows us to directly relate the particle content of the theory with the spectrum of black hole states.
