Why does it always seem like we're looking at one side of a black hole? I know they are pretty much theoretical, but all that stuff has to go somewhere. Is it like the back end of a funnel??

Ok, so does a black hole have to have another (opposite facing) black hole connected at their vertex? Do they form in pairs like this?

Good question...
There is most definitely a "white hole" in theoretical cosmology/general relativity. The math behind it is called Schwarzschild geometry. The complete Schwarzschild geometry consists of a black hole, a white hole, and two corresponding universes connected at their horizons by a wormhole. The problem is that while general relativity allows for white holes, the second law of thermodynamics (entropy increasing in time) does not. The link below explains this with some nice graphics.

A black hole is a point in space (surrounded by a spherical "event horizon").
Depending on what you mean by "other side":
a) the rest of the universe (what is on the other side of the Sun? the rest of the solar system, moe stars, other galaxies...)
b) the singularity: the point towards which any matter inside the event horizon must inexorably go.
Mathematically, something weird happens to our perception of dimensions.
In "normal" space, we can go where we want (freedom in spatial dimensions) but we are condemned to go towards the future along the time dimension.
Inside the event horizon, it could be the reverse: freedom in time, but condemned to go towards the centre. Also, from the point of view of the matter falling in, the "trip" to the centre will take an infinite length of time, which makes the "other side" meaningless (because you get there after a duration longer than infinite).

If you mean a white hole, that is only a theory. and those expel what going into the black hole on the other side of the universe. But there is another theory and one thatis more accepted. That there is no other hole at the endbut where matter space nand time ceases to exist all together and itis at the exact center point. and that point is called the sigularity. And it also mind you is theory.

what makes you so sure that you're just looking on one side of the black hole????
a black hole is a 3 dimensional hole with a singularity in the center.
some black hole are thought to be rotating.
as they consume matter they grow bigger.
some scientists think that black holes may "evaporate"
how in just don't know as even light cannot escape from it(that's why they appear to be black.) others think it may be connected via "wormhole "(even if there isn't any worm in it nor is it a hole.)
to a quastar or a quasi stellar object.
God bless,

Perhaps more black hole.
It's not so simple a question, but I would say everything they've sucked in must be there

yes it is like a funnel
