>to earth?"

Good question.  What many scientists believe is
that most galaxies have black holes at their
centers.  Therefore, the closest black hole to
earth would likely be the one at the center of
the Milky Way -- if it is really there.  There
is good evidence, however, that a black hole
does indeed exist at the center of our galaxy
and of many galaxies.  Incidentally, our solar system
is about 26,000 light years from the center of our
Milky Way galaxy.
