My opinion about =93 black hole=94
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D..
A black hole is a region of space in which the gravitational field is
so powerful that nothing,
not even light, can escape its pull after having fallen past its
event horizon.

=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
..
But to give only such explanation of =93 black hole=94 is not complete.
There is another alternative.
There is another interpretation of =93 black hole=94.
A =93 black hole=94 is not a =93region of space in which the
gravitational field is so powerful that nothing, not even light,
can escape its pull =93 but=85..
but region with very small density (critical density : p =3D 10^-29g/
sm^3).
And the detected material mass of the matter in the Universe
is so small (the average density of all substance in the
Universe is approximately less than p=3D10^-30 g/sm^3)
that the =93 black hole=94 is only a model of our Universe / Vacuum
as a whole .
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D.
