It isn't what's beyond them, it's what's in them.
Black holes, frequently found in the center of galaxies, are the result of large stars that have exploded and then violently imploded into themselves, compressing matter into an infinitely small area.
They are called black holes because they are so dense, with a pull of gravity so strong, that not even light can escape.
Scientists can detect black from the radio waves that are emitted by matter as it orbits and is drawn into them.

Black holes are extremely compact space objects that were once massive stars which collapsed inward due to the force of their own gravity. Consequently, black holes are very dense. If it were not for the effect that black holes have on the objects around them, we would be unable to detect them. A black hole has a powerful gravitational field which traps everything that goes near it. Scientists now theorize that some galaxies have huge black holes in their centers which release tremendous amounts of energy that powers the spectacular energetic events that go on within the galaxy. The fuel for the black hole, scientists believe, may be the trapped gas, stars, and dust that are pulled into the hole. Gas that is pulled into a black hole swirls down into the hole much like a whirlpool. By using a spectroscope, the Hubble Space Telescope has the ability to clock the speed of this gas as it swirls around the entrance to the hole. The speed with which the gas swirls is considered the black hole's signature. By knowing the speed of the gas, the mass of the black hole can be calculated. A black hole in the center of the M87 galaxy in the constellation Virgo, which is 50 million light-years away, has been calculated to have a mass equal to that of 3 billion Suns! An even more effective way of studying black holes is through the use of X-ray observations. X-rays have the capacity to penetrate through gas and dust much better than optical light. With the data delivered to us by X-ray observations and the Hubble Space Telescope, scientists now believe that the presence of black holes explains a lot of the powerful cosmological events which occur in the Universe.

What is beyond the black holes . You mean if you get into one, what is in it ??
Well, if this is the question .. then nobody really knows because no one ever been inside a black hole. I assure you that inside the black hole is very very dense dark environment where you will be squashed and swallowed into the black hole with no return.
Black hole are generated by the death of massive stars that are 3 times and more bigger than the sun. The massive star's mass collapse into its own self and form a hole in space that nothing can escape even light.

The best functional answer that current theory allows is "Nothing". According to current theory, nothing can exit a black hole, no information can ever come out from the inside (or other side) of a black hole. Since nothing can come out, it doesn't matter what is there, it may be nothing or it may be heaven or it may be an ultradense particle soup or maybe another universe or dimension or maybe just a true singularity and there is no "inside". Whatever the case we'll never know so the best answer is ... nothing.

Black Holes and Beyond
Einstein's general theory of relativity describes gravity as a curvature of spacetime caused by the presence of matter. If the curvature is fairly weak, Newton's laws of gravity can explain most of what is observed. For example, the regular motions of the planets. Very massive or dense objects generate much stronger gravity. The most compact objects imaginable are predicted by General Relativity to have such strong gravity that nothing, not even light, can escape their grip.
Scientists today call such an object a black hole. Why black? Though the history of the term is interesting, the main reason is that no light can escape from inside a black hole: it has, in effect, disappeared from the visible universe.
Do black holes actually exist? Most physicists believe they do, basing their views on a growing body of observations. In fact, present theories of how the cosmos began rest in part on Einstein's work and predict the existence of both singularities and the black holes that contain them. Yet Einstein himself vigorously denied their reality, believing, as did most of his contemporaries, that black holes were a mere mathematical curiosity. He died in 1955, before the term "black hole" was coined or understood and observational evidence for black holes began to mount.
Why Study Black Holes?
Here are some good reasons:
Human curiosity: they are among the most bizzare objects thought to exist in the universe.
They should be strong sources of gravitational waves.
As such, black holes should reveal much about gravity, a fundamental force in the cosmos.
Confirmation that they exist will strengthen confidence in current models of cosmic evolution, from the Big Bang to the present universe.
Black holes are all very well in theory, but if they really exist, how do they form?

A black hole is center of most galixies. It is like a very large eating mechine. gulping up any thing in it's path. There are stable black holes(black holes that seem just to be sitting there) and active black holes( sucking in anything in it path). Our galaxy has a stable black hole in it. If you look at space photos of galaxies at there edge you will see eather a flat disk(stable) or a funnel (active). type in galaxy photos on your go line and see what pops up.

A blask hole is nothing more then a very small dense object in space. So heavy it bends space. what is on the other side of a black hole is just more space.

A wonderful imagination and fantasy for science fiction writers. Not really any way to tell otherwise. If you sent a satellite into one, there would be no way for it's radio signals to escape, and of course, it probably wouldn't survive the trip in one piece. Even if it could survive the trip and somehow came out in some other time or place, how could it tell us? Only what mathematicians can theorize, or perhaps we can ask God?

Beyond black holes, there's more space..
Within a black hole there's ultra dense matter..
