Is there anything like 'Black Hole' in reality

Because if it exists, according to Hawking it must be emitting Hawking radiation, this means it would be glowing and it would be bright. But we have not seen anything bright in the middle of our galaxy or some other galaxy. So is 'Black Hole', just a fantasy?

"Is there anything like 'Black Hole' in reality?"

Yes, there is one at the centre of this galaxy. Sagittarius A.

"according to Hawking it must be emitting Hawking radiation, this means it would be glowing and it would be bright."

Hawking Radiation is theoretical, and has not been detected in nature, probably because the effect is too small to be observed.

The basic idea is that the gravity of a black hole at it's Event Horizon causes quantum vacuum fluctuations, which result in a pair of virtual particles, one matter, one anti-matter, they would usually annihilate each other, but at the Event Horizon of a Black Hole, one gets sucked in while the other escapes.

The black hole concept is based on an assumption that matter can crush itself under its own gravitation. That is false.

If you integrate the gravitation of every point in a body acting on a point outside and well away from it, you get a result that allows you to pretend that the mass is concentrated at a single point. That is called center of gravity or center of mass. As you move closer to the body you notice that some points are more massive, and net gravitation depends on which points you are near to. As you go below the surface, gravitation from the sides cancels, leaving only the gravitation from points beneath you. When you reach the center then all gravitation cancels and there is no net force.

So the foundational assumption of the black hole hypothesis is nonsense.

The thing in the middle of our galaxy IS bright. Have you not seen pictures of it? look at this one (http://www.windows2universe.org/the_universe/images/galaxies/m31_small.gif). What's that in the middle? A glowing thing. A super-massive black hole.
