I could venture an answer about singularitys and the unfortunate events that will transpire if someone 'enters' a blackhole but as others have done this rather well let me just add an important caveat.

There's a good chance black holes DON'T exist! I've read Hawking's book - he says as others have that the laws of physics break down inside a singularity - some people have interpreted this to mean that reality breaks down - if you think about that its entirely non-sensical - how can the laws of physics 'break down' - they could change, sure, it would just colour our ideas about exactly what physical laws are - so what can he mean?

Black holes are indeed predicted by General Relativity by the singularity itself is of infinitesimal size. Very small things are described (very accurately) by quantum mechanics, very massive things by relativity - both are incredibly accurate but they don't work well together. Since blackholes are the domain of both field it highlights the problem. All Hawking said is our ability to predict whats going on breaks down because the two theories don't work together.

There have been reformulations which take quantum mechanics more in to account - search for 'gravastars' or 'black branes' which are both candidates for what a black hole REALLY is.

inside a black hole there is what is known as a singularity. A singularity is a point with a huge mass that occupies no space, so that it has an infinite density.
If someone went inside a black hole they would not be able to get back out because you need to travel faster than the speed of light to get out (and going faster than the speed of light is not allowed). As you approached the singularity of the back hole time would start to slow down for you, and the closer you got the slower time would run so it would take forever to reach the center - not a very nice fate.

There is actually nothing inside a black hole. If somebody goes into a black hole, it will crush you instantly because of the huge amount of gravity.

hi im a photon please follow me on a wild ride into and back out of a black hole. let us begin in normal space as you should feel comfy here being familiar with it and all. Stay close now because time seems to be changing here as we approach the event horizon of the black hole, this is a really nice one it has the exact same mass as the Milky Way galaxy! now in normal space the speed of light is the speed limit for just about everything but as we penetrate now by falling into(penetrating) the event horizon all the laws of physics change because we are no longer in normal space its so dense and hyper in here its hard to tell whats going on but fear not we wont be here forever, I got a confirmation that something amazing is about to happen! I can tell by the excitement picking up in here that the black hole is now being acted upon by two new forces, they are angular acceleration and tidal force. We must have been in here for a while because the black hole is now approaching another black hole, I'm told it has the same mass as this one does. Lets see what happens next. The two black holes are not on a direct collision course that rarely happens, rather they are beginning to orbit one another around a central axis. Now dig this both black holes have enough gravity to restrain light their gravitational power is therefore capable of accelerating things faster than light within their event horizons, whats more if we consider and ad to this the angular acceleration the two black holes are exerting upon each other the two black holes will soon be orbiting one another at a speed of about 10 times the speed of light around a central axis with their event horizons just barely touching each other. Can you see how this is happening now look at how the black hole is foot ball shaped now rather than spherical. Here we go hold on tite! using the gravitational power of the second black hole we now are escaping from the gravitational power of the one we were in, we have to do this at the central axis they are orbiting one another with an orbital period of about 1 second so if we want to be shining ourself in the direction of earth we have a one in sixty chance of this unless we go now! You blinked! Let me explain what just happened. We came out faster than the speed of light were accelerated around the second black hole and were tossed into normal space agean where we must now follow the speed limit. Behind us is a Pulsar flashing once every second and in front of us is the earth, Wasnt that neet?!!

A black hole is an object predicted by general relativity with a gravitational field so strong that nothing can escape it — not even light.

A black hole is defined to be a region of space-time where escape to the outside universe is impossible. The boundary of this region is a surface called the event horizon. This surface is not a physically tangible one, but merely a figurative concept of an imaginary boundary. Nothing can move from inside the event horizon to the outside, even briefly.

Let's suppose that you get into your spaceship and point it straight towards the million-solar-mass black hole in the center of our galaxy. (Actually, there's some debate about whether our galaxy contains a central black hole, but let's assume it does for the moment.) Starting from a long way away from the black hole, you just turn off your rockets and coast in. What happens?

At first, you don't feel any gravitational forces at all. Since you're in free fall, every part of your body and your spaceship is being pulled in the same way, and so you feel weightless. (This is exactly the same thing that happens to astronauts in Earth orbit: even though both astronauts and space shuttle are being pulled by the Earth's gravity, they don't feel any gravitational force because everything is being pulled in exactly the same way.) As you get closer and closer to the center of the hole, though, you start to feel "tidal" gravitational forces. Imagine that your feet are closer to the center than your head. The gravitational pull gets stronger as you get closer to the center of the hole, so your feet feel a stronger pull than your head does. As a result you feel "stretched." (This force is called a tidal force because it is exactly like the forces that cause tides on earth.) These tidal forces get more and more intense as you get closer to the center, and eventually they will rip you apart.

For a very large black hole like the one you're falling into, the tidal forces are not really noticeable until you get within about 600,000 kilometers of the center. Note that this is after you've crossed the horizon. If you were falling into a smaller black hole, say one that weighed as much as the Sun, tidal forces would start to make you quite uncomfortable when you were about 6000 kilometers away from the center, and you would have been torn apart by them long before you crossed the horizon. (That's why we decided to let you jump into a big black hole instead of a small one: we wanted you to survive at least until you got inside.)

What do you see as you are falling in? Surprisingly, you don't necessarily see anything particularly interesting. Images of faraway objects may be distorted in strange ways, since the black hole's gravity bends light, but that's about it. In particular, nothing special happens at the moment when you cross the horizon. Even after you've crossed the horizon, you can still see things on the outside: after all, the light from the things on the outside can still reach you. No one on the outside can see you, of course, since the light from you can't escape past the horizon.

How long does the whole process take? Well, of course, it depends on how far away you start from. Let's say you start at rest from a point whose distance from the singularity is ten times the black hole's radius. Then for a million-solar-mass black hole, it takes you about 8 minutes to reach the horizon. Once you've gotten that far, it takes you only another seven seconds to hit the singularity. By the way, this time scales with the size of the black hole, so if you'd jumped into a smaller black hole, your time of death would be that much sooner.

Once you've crossed the horizon, in your remaining seven seconds, you might panic and start to fire your rockets in a desperate attempt to avoid the singularity. Unfortunately, it's hopeless, since the singularity lies in your future, and there's no way to avoid your future. In fact, the harder you fire your rockets, the sooner you hit the singularity. It's best just to sit back and enjoy the ride.

As Steven Hawking's theory says, there is nothing inside a blackhole. Ever heard of a wormhole? well, it's the same thing with blackhole. Transfering from one black hole to another.

If anyone goes in the blackhole, they are gonna get transferred to another blackhole, orrr they are gonna get ripped apart painfully....=( =( =( =(
