    "In 1974, Hawking showed that black holes are not entirely black but emit small amounts of thermal radiation.[29] He got this result by applying quantum field theory in a static black hole background. The result of his calculations is that a black hole should emit particles in a perfect black body spectrum. This effect has become known as Hawking radiation. Since Hawking's result, many others have verified the effect through various methods.[81]"
