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.

=========================.
But to give only such explanation of “ black hole” is not complete.
There is another alternative.
There is another interpretation of “ black hole”.
A “ black hole” is not a “region of space in which the
gravitational field is so powerful that nothing, not even light,
can escape its pull “ but…..
but region with very small density (critical density : p = 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=10^-30 g/sm^3)
that the “ black hole” is only a model of our Universe / Vacuum
as a whole .

And nobody know that the “ mini black hole” keeps in itself.
What is “ mini black hole “?

Into what e = elementary charge unit, m_e mass = the electron and m_p = mass
of the proton is.
By this gravitational force a motion which induces a counter-force
(counter-gravitation) which agrees with this one, the electric charges is
caused in another particle.
Q ^ 2 = m_eT* V ^ 2 *r
Into what m_eT = mass of an elementary particle (eT), V = speed on a stable
circular orbit and R = radius of this trajectory is
By the ratio of gravitation and electric charges, that is the state of
motion and the together storage of eT to cluster the different particle
types are valid.
The principle in nature is therefore electric charges are very simply
produced by motion this one covers the gravitation (compensatedly). This has
the consequence that it does not give any hypothetical particles for
Gravitation. (Gravitonen) exactly, as little as photons.
This behaviour is exactly, like in cosmology so correct at the construction
of atoms

If the motion is rotation , or movement in a closed circuit, as in
vortex motion, then the inertia will be localized, and thus have
momentum.
The distinguishing characteristic of the so- called blackholes is
their Localized Persistence of Individuality, and this is the same as
vortex motion.
Wave motion is not localized, as it will not revert to original form,
when distorted. but will travel in the direction normal to the new
wavefront, their being no persistence of individuality or memory of the
original form of the wave.
On the other hand, a vortex ring , if distorted from the circular , or
elliptical will spontaneously revert to it's original form ,
displaying persistence of individuality, and memory of it's original
form.
The so called event horizon of a blackhole is the interface closed
circuit of vortex motion, within the medium, the resulting reaction not
allowing light to escape, as it is no longer a wave, in the normal
sense, but still an energy source, contributing to the inertia and
momentum of the vortex, or so-called blackhole.
