  Small,quiescent black holes can be considered as candidates for the missing
dark matter of the universe,and as the core energy source of ball lightning.By
means of gravitational tunneling,directed radiation is emitted from black holes
in a process much attenuated from that of Hawking radiation,P SH, which has
proven elusive to detect.Gravitational tunneling emission is similar to
electric field emission of electronsfrom a metal in that a second body is
involved which lowers the barrier and gives the barrier a finite rather than
infinite width.Hawking deals with a single isolated black hole.
