Black Hole Evaporation Phenomenon
The discovery of a temperature seen by an accelerated fiducial observer adds a new dimension to the equivalence principle. Identical thermal effects can be expected to happen near the horizon of a very massive black hole. Nonetheless, in the case of a black hole a new phenomenon can take place, that is, evaporation. In contrast…

The Decay of Black Holes
Black holes are areas of space where the gravity is so strong that nothing, not even light can escape. However, that was the understanding held until 1974, when the astrophysicist Stephen Hawking proposed that black holes are indeed radiant objects, emitting a variety of particles by a mechanism involving tunnelling through the (gravitational) potential barrier…

The Equivalence Principle & Black Holes
The equivalence principle is one of the laws of nature and it is connected with the nature of gravitation. In general relativity theory, the equivalence principle states that a gravitational field is locally equivalent to an accelerated frame. To be precise, it says that a freely falling observer or system will not experience the effects…
