  The isolated black hole radiation of both Hawking and Zel'dovich are
idealized abstractions as there is always another body to distort the
potential. This is considered with respect to both gravitational tunneling, and
black hole "no-hair" theorems. The effects of a second body are to lower the
gravitational barrier of a black hole and to give the barrier a finite rather
than infinite width so tha a particle can escape by tunneling (as in field
emission) or over the top of the lowered barrier (as in Schottky emission).
Thus radiation may be emitted from black holes in a process differing from that
of Hawking radiation, P SH, which has been undetected for over 24 years. The
radiated power from a black hole derived here is PR e ^2__ PSH, where e ^2__ is
he ransmission probability for radiation through the barrier. This is similar
to electric field emission of electrons from a metal in that the emission can
in principle be modulated and beamed. The temperature and entropy of black
holes are reexamined. Miniscule black holes herein may help explain the missing
mass of the universe, accelerated expansion of the universe, and anomalous
rotation of spiral galaxies. A gravitational interference effect for black hole
radiation similar to the Aharonov-Bohm effect is also examined.
