Have you ever wondered about what a black hole is? I was wondering if it could be a solid object. Like a neutron star, only it has gravity. Objects don't get sucked it, but rather broken apart and fit on top of each other atom by atom. And with the gravity even pulling in light, it would appear black.
Is this a possibility?

We don't think they are holes. The theories about wormholes and such arise because we aren't sure what will happen to matter when it is compressed into an infinately small point which is what a black hole is. It supposedly could compress things to be smaller than atoms making them no longer matter as we know it.

One of the end points of gravitational collapse, in which the collapsing matter fades from view, leaving only a center of gravitational attraction behind. General relativity predicts that if a star of more than about 3 solar masses has completely burned its nuclear fuel, it should collapse to a configuration known as a black hole. The resulting object is independent of the properties of the matter that produced it and can be completely described by stating its mass, spin, and charge. The most striking feature of this object is the existence of a surface, called the horizon, which completely encloses the collapsed matter. The horizon is an ideal one-way membrane: that is, particles and light can go inward through the surface, but none can go outward. As a result, the object is dark, that is, black, and hides from view a finite region of space (a hole).

A black hole is the last stage of a star after it has gone beyond the nova and super nova stages. It has exremely high gravity which does draw or such other objects in including light. The objects are then either crushed or torn apart by the g-forces inside the hole.The boundries of a black hole are called the event horizon, once you get there, you pretty well are not coming back.

Precisely what a black hole is isn't known. That's because beyond a certain point (..the event horizon) within the gravitational sphere of a black hole all the known laws of physics break down. For instance, mathematically trying to determine what the exact center of a black hole is returns a solution that an object of infinite mass (..all the mass in the universe) contained within zero volume is located there. For this reason it's impossible to know beyond any doubt what the final fate is of material drawn into a black hole.
P.S.
Neutron stars have gravity :)

Black holes are "solid objects" the thing is we think it is an infinitely small solid object. The matter that is sucked in does get broken apart and the mass is added to that of the black hole, like you suggest. But the gravity is so intense that particles as we know them cannot exist.

The size of a black hole depends on its mass. Very small mass ones will rapidly evaporate due to Hawking Radiation. Most of the one that we see discussed are in multiples of solar mass. If they do exist they would not contain atoms but would most likely be much denser than a quark star. Often we forget as the mass of the black hole increases that its density decreases. For extremely large mass black holes things would appear as they do here. You are in one right now. Our universe is a black hole.

Actually the theorics affirm that the gravity is so strong that the phenomenon known as space-time is broken and that is the reason they are called black holes.

In referring to "black-holes", Hawkin, was using,"hole", as a metaphor for the un-explainable. It is simply an anomaly with an infinite amount of mass ( they think ) Many theorize that it is a hole in space time ... where you go in ( dead ) and pop-out in an another location in space ... bottom-line ? no one really knows.

i guess that could be i can tell uve really thouht about this and thats a great question. But black holes are still in the stage of theroys and it may be awhile befor we find out.

It's called a black hole because it's not visable (black) and everything falls in it (like in a hole).
The term doesn't describe it's physics.
