...makes stuff go in gravity? and what is a black hole do they go away. what makes stuff go in so fast gravity with so much force. what happens to the stuff that goes into the black hole another dimension does it shrink
what makes matter go in so fast
 
Have you considered reading about black holes first? Its amazing how much information is available everywhere about black holes.

A black hole's event horizon (the point where nothing can move fast enough to escape) is a sphere if the black hole is not rotating - if its rotating the shape is ovoid.

Only the tiniest black holes go away (evaporate) due to Hawking radiation - black holes the mass of a star or more do not go away.

Not sure what you mean by "what makes stuff go in gravity" - gravity is a force that pulls matter. Gravity makes "stuff go in gravity". And I don't know what you mean by "go in so fast gravity with so much force" - what are you asking?

The matter that enters a black hole becomes part of the mass at the centre (the singularity). It is not theorized that it goes into another dimension, though its possible that black hole singularities are doorways to the other universes ("branes") in the multiverse.

Read this for starters, then check out the external links in the article:

Black holes are believed to be the process of a dying star: Yellow star, red giant, (shrink in on itself) white or brown dwarf, and then gravitational squeeze so hard it punctures a hole in space/time.
Yes, I think it is a sphere, but even if you could see it's dimensions (you can't because light can not escape it), I think it still would appear more like a hole than a sphere, because it's broke the dimensions we can see.
They also are believed to be different sizes--most microscopic (see the Hadron Collider scare), and now are known to move! Even the big ones.
 
A black hole is a very dense sphere that does not even let light escape.

Black holes slowly evaporate because they radiate very small radioactive particles constantly.

Gravity is the attraction between two masses, the black hole has a large mass so any other mass would be attracted to it (sucked in)

A black hole wont blast you into the fourth dimension (since technically we are present in all dimensions at once)

If you meant will it send us into a different universe, there is no scientific evidence to prove either side. We cannot say for sure whether it will or wont. I am leaning toward the will side.
