My opinion about “ black hole”
=================================..
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.
http://en.wikipedia.org/wiki/Black_hole
=========================.
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).

Black holes as so far described do not exist.

How can you talk about existence with black holes?

I've seen presentations about this curvature of space in which the black
hole, became sort of a tunnel. I believe that they even mentioned white
"gates" (i forgot the exact concept) as the other side of the tunnel.

With other words, a black hole as universe's recycling machine.

John ( n...@ hotmail.com) ask:
For a non-specialist, what's the conclusion?
=========.
1.
In 1900 Planck found what “ black body” / a model of Vacuum /
can radiate . The radiation goes only by “ quanta” particles (h).
This kind of radiation is electromagnetic radiation.
2.
In 1974 S. Hawking found what “ black hole” / other model of vacuum/
can radiate . This is another kind of radiation.
This radiation explain the thermal spectrum radiation of the
beginning
of star formation ( gravitation).
http://en.wikipedia.org/wiki/Hawking_radiation
3.
So, we have two different kinds of radiation:
electromagnetic radiation and thermal radiation.
4.
Hawking radiation has never been observed because it begins
from very small “ micro black holes “ in the vacuum. ...

What accounts for the profound gravity if there is no matter? Density
without matter?
