Hawking radiation formula


m: mass

a: gravitational acceleration d: distance the mass mfalls

The mass is the mass of a virtual photon in our case and the distance is the distance a virtual photon moves in its lifetime. Since virtual photons have such a short lifetime they won’t get very far during that (24 nanometers for a virtual photon of orange light). So we can assume the gravitation to be constant and therefore use this formula.
