My understanding is that Hawking's radiation is a theory used to explain how blackhole's conserve energy. For example, we think blackholes grow in size as they consume matter. Any particle that enters the Schwarzchild radius (SR) of a blackhole is absorbed. QM purposes that virtual particles in the quantum field 'pop' in and out of existence all the time, but that they come in particle/anti-particle pairs that quickly annihilate one another, thus conserving energy and momentum in the universe. Hawking used this notion to theorize that virtual pairs that happen to 'pop' into existence on the event horizon (SR), are split up and do not annihilate eachother as they usually do. One particle 'falls' into the black hole, while the other escapes and appears as Hawking Radiation. Since the black hole grows fractionally by swallowing one particle, and since the other particle in the pair is emitted as radiation, energy and momentum are conserved. Is this a fair description of Hawking radiation? Also, if I made an error, please correct it. Thank you.
