Title What is Hawking radiation? Media name/outlet Science Focus Media type Web Country/Territory United Kingdom Date 16/03/22 Description The idea of Hawking radiation is based on the fact that empty space isn’t actually empty. This is perhaps a difficult concept to grasp. Although empty space contains no mass, no particles or quanta of energy, the quantum fields which define them still exist in the vacuum of space.
The usual explanation is that these fields, because they are not required to have zero energy, can create pairs of ‘virtual particles’, normally a particle-antiparticle pair that quickly annihilate each other. But near a black hole, the explanation goes, it is possible for one of those particles to disappear inside the black hole and be lost forever, while the other one escapes as Hawking radiation.URL https://www.sciencefocus.com/space/what-is-hawking-radiation/ Persons Alastair Gunn
