In fiction, black holes can be all kinds of things. In science, they're something predicted by theory and apparently confirmed by observation, but there's still a lot scientists don't know about them. You can find out what is known from any number of web sites.

This idea usually promoted by science fiction is that a black hole is a natural "hole" in our existence, perhaps this is because of the ambiguity of the name we have termed for them.
There is no hole in a black hole. Imagine it more as a tiny star, like our own but much smaller. It is however much denser, it's mass probably exceeds many times over all the mass in our solar system. It is so heavy as a result that whilst things far enough away can orbit it like any other star there is a point, an "event horizon" that if crossed means an object will be pulled towards it. This happens with conventional stars but is closer to the star and instead it just burns up. When a object crosses the event horizon here it is drawn in and crushed.
Because the star is so massive and heavy it's gravitational pull makes it impossible for even light to escape it. This is the reason for it's darkness and the term black hole. Many people seeing the "einstein"-ian model for a black hole get the wrong idea. Einstein favoured a model of a rubber sheet with a ball placed in it to explain gravity in relation to relativity. Modern scientists explain black holes by using a image of a small ball bearing or object of similar size pushing down to create a sort of whirlpool or very deep depression in the sheet. It isn't hard for people to think "well it's stretched so far, why doesn't it break?" and this makes the thought of gateways attractive and easier to grasp, however it is wrong because the image is misunderstood. A massive object doesn't pull space "down" onto another plane, but inwards, it doesn't move above or below our 3 dimensions of space. The model goes wrong because it is two dimensional and uses the earth's gravity to illustrate it by pulling the sheet "down" but leads to a lot of confusion.
The only possibility of evidence for such a thing would be in the mass in a black hole could be accurately measured and if the mass inside was not equal to the mass of the star's orignal mass+ what had fallen into it. Of course this experiment is impossible because of measurements and not knowing it's original mass. But if they were unequal it would point to mass going somewhere "else". But this should not occur, because black holes do not go anywhere, they are points in our universe. Things falling into them are crushed into their base particles or energy, E=mc2 measn energy and mass are interchangealbe which allows a black hole to take unescaping light or objects that fall into it and turn it into it's mass, crushing it to become like the star. Nothing comes out in a different place or escapes.

No. Black holes are not gateways. They might not even be black holes but Dark energy stars. You'd have to read alot of Stephen Hawking to get a firm idea of what the might be but new realm of existance inside a black hole is not possible.

We are not sure. Nothing ever comes back out so we don't know where it leads. But it may not lead anywhere.
Perhaps over billions of years everything is going to contract into a 'superior' or 'master' black hole. When everything becomes so dense it my lead to another 'big bang' thereby our current universe is gone and an entire new one will be created.
Or at least so I teach in high school science class.

Some say another dimension... it's all theory as to what's inside.

until someone goes into a blackhole then returns to tell the tale . . . it will all still be speculation and theories.
current theories suggest other dimensions, so . . . . who knows???

How the heck are we supposed to answer that, thats a question that
can never be answered, seriously. This question goes along with the question about what happens after death? i mean, you just wasted points asking a useless question that nobody can answer.

you die in a black hole
the gravity will kill you
