WebApr 25, 2024 · Its energy is equal in size to the pair with the opposite sign. This then falls into the black hole along with one of the particles, decreasing the mass of the black hole overall. The horizon of the black hole gets in the way of recombining some virtual pairs, so these conversions virtual->real will happen. WebNov 15, 2011 · For a particle to escape a black hole, a quantum fluctuation must occur near a black hole's edge. When this happens, sometimes one particle will tunnel out before the …
WebMay 23, 2024 · In order to have a pair of real particles with zero total energy, the only physical possibility is that the positive-energy particle can escape to infinity, while the negative-energy particle falls into the black hole. In this way, the strong gravitational field of the black hole can convert a virtual particle–antiparticle pair into a pair of ... WebAug 12, 2013 · Hawking radiation is the thermal radiation predicted to be spontaneously emitted by black holes. It arises from the steady conversion of quantum vacuum fluctuations into pairs of particles, one of which escaping at infinity while the other is trapped inside the black hole horizon.
