Question

In Haskins Radiation why do negative energy virtual particle goes inside black hole and positive virtual particle escape?

Answer 1

Answer:

This rotates its Killing vector so that its energy becomes negative and the pair have no net energy. This allows them to become real and the positive particle escapes as Hawking radiation, while the negative-energy particle reduces the black hole's net energy. Thus, a black hole may slowly evaporate.Hawking radiation is black-body radiation that is predicted to be released by black holes because of quantum effects near the black hole event horizon. It may happen that one of these photons passes beyond the event horizon, while the other escapes into the wider universe ("to infinity").
