What types of radiation does a black hole emit?
Well, theoretically all singularities rotate very fast, but that does not really matter to this question. A black hole itself does not emit gamma radiation, obviously any radiation that got too close would be immediately absorbed, but the atoms being crushed in the accretion disk (the area just outside the event horizon where matter starts fusing together in order to fit in the ever-shrinking space available for it) do emit this gamma radiation. Neutron stars actually do emit gamma radiation from their poles as they slowly reduce their angular velocity over time. The energy has to go somewhere, so it turns into radiation. However, a black hole does not emit this radiation in the same way. Instead, a black hole’s event horizon emits something known as Hawking radiation. This radiation is incredibly weak and (theoretically) undetectable, but should exist mathematically. It works like so: 1. Two opposite particles appear at random just outside the event horizon (this can happen according
