if black holes are accepted as fact, and matter and light are sucked in due to a high gravitational force,then it must go somewere? if it passes through the black hole and emerges on the "other side" as a white hole as has been stated by others,then surely we would have found a white hole by now. as in all that light and matter shooting out into space must be vissible from anywere in the universe? I mean this thing sucks in stars..

you make a good point. but the answer is white holes don't exist. they break several scientific laws now and aren't really considered an option. anything sucked into the black hole is just added to the singularity (central point) and it stays there for billions of years until, very slowly, the black hole radiates off all of its mass, thats called hawking radiation.

If you approach a black hole too much, you will cross the so-called event horizon: beyond that limit, even light cannot escape (what astronomers observe is the radiation emitted by the hot gas approaching the event horizon).
All matter which enters into the horizon falls into
the so-called singularity, where general relativity formally predicts an infinite density: we need a new theory unifying gravity and quantum mechanics to predict what really happens there.
If Hawking is right, when taking into account quantum mechanics all the matter in a black hole will evaporate after a very, very long time, transforming into radiation.
There is indeed a solution of the Einstein equations, the so-called Einstein-Rosen bridge, which could in principle connect two regions of our universe or of different universes: unfortunately this connection is unstable,
and nothing can travel between the two extremities. As another possibility, one could try to create a wormhole, as suggested by the physicist Kip Thorne (see also novel Contact written by the astronomer Carl Sagan), but this is different from black holes, highly hypothetical and not so easy to realize...

A black hole is referred to some as the universe's hoovers.
A black hole body is conical shaped. The wide bit - the 'black hole' is surrounded by the 'event horizon' which is observed as a swirling mass of various matter.
At the other end of the black hole, the point of the cone, it is called a singularity.
Everything that is sucked into the black hole around its event horizon is spat out as sub atomic particles at the singularity.
This answer represents the latest thoughts on the physics of black holes.

If a black hole could exist any matter entering it would be confined in a non dimentional point at the center.
A black hole would be an area in space that could not separate two objects.
It would be a 3 km diameter sphere contining no space with no way of separating it's center from the event horizon which would be 1.5 km from the center.

Yes, it goes somewhere: into the black hole. There is no "other side". Yes, we probably would have noticed white holes by now if they existed, but there's no good reason to think they do.
"Black hole" is a bit of a misleading term (as well as, apparently, being an extremely rude one in Russian), since it's not really a hole at all. Anything that falls in just gets squished together with whatever else is in there.

Sorry, but since a black hole emits gravity in all directions, the light cannot escape out the other side.
There are theories that the black hole opens a gap in space and time and the energy can escape that way.
I personally believe, that energy escapes from the black hole via the gravity field.

u got a point
BUT a black hole is not a hole its like a pressure cooker it sucks stuff in and squishes them to unimaginable levels the stuff it sucks is turned to other forms of energy and particles maybe they turn to dark matter : / as well our knowledge is still very basic,
black holes emit heat and x-rays and other particles that's what the stars and stuff turn into.
what I'm trying to say is that black holes are not holes they are points of almost <<
so inshort black holes turn stuff into other stuff and don't transport them to other dimentions BUT i might be wrong its not like I have a space ship and went there to study them.

Why does the matter have to 'go' anywhere. When you put an object into a bag it doesn't 'go' anywhere, it just adds to the overall content of the bag. In the case of black holes, the bag just gets bigger.

black hole sucks in everything and light cannot escape through it so there is noyhing as white hole and everthing reachs its surface

A 'Black Hole' is not a tunnel it's a bottomless pit.
