(it is not really a hole)

A black hole is what remains of a massive star when it "dies." All a star is, is basically a huge fusion reactor. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star.
*(The balance between the gravitational forces and the explosive forces is what actually defines the size of the star.)As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed, and extremely massive, core. The core's gravity is so strong that even light cannot escape. A.K.A- blackhole.

When someone with the intellect of Steven Hawking wrestles with the concept daily - what do you really think a layman's grasp of the concept is? A "hole" in the sense that matter "falls" into it due to its immense gravitational field. A quantity of mass and energy so great that it collapses under its own gravitational field. A singularity that distorts and deforms space so much that anything moving within its field is sucked into it. "Black" because the field is so great even light cannot escape. Yet it emits radiation?? Not an easy concept for anyone!

A black hole is a huge chunk of mass. Gravity is proportional to mass. Nothing to do how dense it is. SO when the mass reaches a critical stage the gravity is so huge that the light doesn't escape from it. So it appears black. So there is no hole there. It is big spherical ball producing a large gravitational force.

It is a massive gravitational hole. they call it black but in fact its invisible because no light can escape from its huge gravity and it sucks everything in universe into it .to where? nobody knows. scientists say that if something can pass through blackhole and come out from the other end of it, it may even be in another dimension and another time. they recently found out that black holes are essential parts of universe and they say that they need new physic to describe it.

A hollow via definition is a around void of a surrounding substance.provided that no longer something is in a hollow we see it as black. the belief of black hollow stems from a answer of Einsteins field equation of singularity whose radius is defined by way of fact the "Schwartzchild's Radius". hence as in line with definition of singularity a black hollow is in fact an atomic mass shape. The greater vast a Black hollow is, as in line with Schwartzchild's radius and quantity the fewer its density. If the sunshine radiation from Stars does not escape the form horizon of the Universe than the Universe could be the main important quantity with the smallest density than in own discrete inherent platforms.hence this might in good shape the Schwartzchild definiton of Black hollow. So the Universe has been mentioned yet in basic terms via the barriers of human beings.

If you start from feet and than move up towards leg and if you go a lil bit up you gona find black hole.

some time sits white in color as well but , it is termed as BLACK hole

I Dissagree wtih people who say things cannot escape Black whole, things can go in and come out as well.

Black holes can be thought of as sort of electro-magnetic "grounds" between different neighboring dimensions; even points of contact between the "= & -" of inter-relating membranes of matter and energy. They may be pathways between different Dimensions or Universes but we'll never know firsthand in our lifetimes at least. They are pathways to the "lost" dark matter and energy scientists can't seem to find yet.

Define know? We have a generally accepted theory that they're the point in space where a super dense object has collapsed on itself and is exerting a gianormous gravitational pull on all things nearby. What are they exactly? We dunno, we can't get close enough to find out, I mean they might be the anus of a giant space slug.

It's simply a name coined for a collapsed star that light can no longer escape.

That's the simplest way to describe it.

Something enters, it's never heard of again - not even light.

it is an area in which the gravity is so strong that not even light can escape, therefore give it the term "black"
