“To perform this calculation, we had to

guess how a black hole interacts with the Hawking radiation field that

surrounds it. This is because there currently is no theory of quantum gravity

that could suggest such an interaction. However, it appears we made a

well-educated guess because our model is equivalent to Hawking’s theory in the

limit of fixed, unchanging black holes.

While our model is just that—a model—we were able

to show that any quantum interaction between black holes and Hawking radiation

is very likely to have the same properties as our model”
