A black hole is a concentration of mass great enough that
the force of gravity prevents anything from escaping it
except through quantum tunnelling behaviour (known as
Hawking Radiation). The gravitational field is so strong
that the escape velocity near it exceeds the speed of
light. This implies that nothing, not even light, can
escape its gravity, hence the word "black". The term "black
hole" is widespread, even though it does not refer to a
hole in the usual sense, but rather a region of space from
which nothing can return.
