Not Photon pairs pop up, but Fermion pairs seem to do, according to Quantum FFF String Theory, direct dressed up by their own gluons into compound Quarks to form Plasma.
The black hole horizon is in fact a vacuum collider of opposite rotating vacuum particles creating mainly fermion pairs dressed up Quarks and plasma. see: Ball Lightning Comets and Sprites.
