A black hole is a collapsed star that has tremendous pressures that draws in everything...even light. That is why it is invisible. It is not a portal as some people may dream.

A black hole is a concentration of mass
At the centre of the black hole, well inside the event horizon, general relativity predicts a singularity, a place where the curvature of spacetime becomes infinite and gravitational forces become infinitely strong.
It is expected that future refinements or generalisations of general relativity (in particular quantum gravity) will change what is thought about the nature of black hole interiors. Most theorists interpret the mathematical singularity of the equations as indicating that the current theory is not complete, and that new phenomena must come into play as one approaches the singularity.[12]
The cosmic censorship hypothesis asserts that there are no naked singularities in general relativity. This hypothesis is that every singularity is hidden behind an event horizon and cannot be probed. Whether this hypothesis be true remains an active area of theoretical research.
Another school of thought holds that no singularity occurs, because of a bubble-like local inflation in the interior of the collapsing star.[13] Radii stop converging as they approach the event horizon, are parallel at the horizon, and begin diverging in the interior. The solution resembles a wormhole (from the exterior to the interior) in a neighborhood of the horizon, with the horizon as the neck.

In a black hole is an event horizon. This event horizon is the point at which matter disappears because of acceleration. Einsteins general relativity and the Lorenz transformations describe this. I recommend reading Special and General Relativity Explained or some such title by Einstein. He walks you through it quite well. Basically what happens tho is that matter compresses upon the axis of movement as you approach the speed of light. In a black hole the gravity accelerates an object to the speed of light. As this happens the object smashes to almost no length. As this happens, time dilates as well. This means that as speed approaches the speed of light, time stretches out. So to someone at an event horizon, time is very close to stopped for them, but in the inertial frame of outside the black hole, the entire universe is born and dies in less than a second. This means that perhaps nothing actually reaches the event horizon, begging the question, what is causing the intense gravity? So yes, this is a crazy answer, but we live in a crazy place called reality.

Energy appears to be the most logical answer. Some theories suggest that inside the event horizon (The last point in the sphere around a black hole that anything can escape from) is where matter stretches out. If I remember correctly, it's called spagettification. Some people suggest it is a tear in the fabric of space time and behaves as a porthole to other universes. But we can observe some attributes of a black hole, such as the jets of high energy particles streaming from it's poles, as well as magnetic fields that interact with the matter outside of the event horizon which is believed to be the primary reason that enables matter to fall in, rather than stay in orbit outside of the black hole.

One theory I read about a while ago is that black holes gather energy and matter for millions or billions of years, then they reach a sort of critical mass and explode. When they explode, they tear a hole in the universe and create their own space inside a brand new universe. Thus, the Big Bang occurs in a new universe. The new universe is inaccessible from ours because the only passage to it is now gone (the black hole no longer exists in our universe).

Theoretically, there is a mass (usually in the order of several solar masses) of zero dimensions, or a singularity, at least in a black hole's simplest form. Thus, it is not really a "hole" per se, just a massive singularity from which at a certain radius no form of matter or energy may escape its gravitational pull. Or, in relativistic terms, about a certain radius it warps spacetime by an infinite amount.

Intense gravity
an implosion, an anomoly in space that could be a collapsed Star !
See Stephen Hawkings's "Black Holes and Time Warps"

Our laws of physics (as we know them) break down inside a black hole, humanity will need to develop an entirely different set of physics laws to describe the interior of a black hole.

I think Black hole which is taking everything inside.........does'nt have "solid centre " kindaof....( if we consider its eating things and all are collecting inside slowly or fast...watever.)
I hope that while Time wrap is happening in or near black hole, their might be chances that between event horizon and the centre of hole itself........some other unknown actions get "triggered on" and the things going into it, are getting their state changed to another things or get "TRANSMITTED " to other"place" or "side" in universe.
Imagine what do you do when suck air into mouth to give a big BLOW to fire or baloon......You sometimes clearly donot suck air to your ur stomach.....u just trap it in your mouth itself.....but the pumping 'IN' u use is from inside the stomach. That something is happening in Black holes also...i believe...untill there comes clear picture.
Give a thought to this....may be there are chances that my theory will prove to be true.

Can't give you an actually answer, as our current physics are not sufficient to describe the conditions "inside" a black hole.
