Black holes are indeed collapsed stars and they discovered them as they discover new stars, by spectral analysis of the radiations (including light) from out there. I think you guys have been affected by to many movies tho. They are not such giant vacuum holes as in the movies. Indeed the gravity is extremely powerfull and indeed they do curve light, but do you ever knew that our little sun curves light by 0.25 degrees? It's proven. So you need more gravity for more curving.. so nothing SF, just physics.
But what happens when so much gravity is condensed in one place is hard to guess so we'll have to gather more evidence before we will know what really happens there.

Mmmmm - what a very interesting question.
However, I have a far more interesting question.
Who is it that is going round space digging these black holes?
Also, what happens to all the stuff that comes out of the black hole? Does that become another planet?
Then we come to the absorbing question of, why would anyone WANT to dig a black hole in space?
And now we come to the mind boggling answer.
GOLF
Yep - Golf.
It must be some supreme being up there somewhere who is building a golf course - and why not?
The new planets are the hazards.
Okee Dokee - now we have established that - why would this supreme being build a golf course just for him/her self?
Well, of course He/She wouldn't, would they?
So there must be more than one supreme being.
This is getting interesting, Mmmm?
Right, so these supreme beings are building a celestial golf course. What if they have now finished?
What are they going to use for a ball?
It can't be the planets they've created from digging the black holes, coz those planets will be black - stands to reason - so it must be the older planets.
Therefore, is Earth about to be whacked into a black hole by an enormous golf club?
Let's suppose it is.
Well, as we all know (I'm working jolly hard for my 2 points, aren't I?) all the planets hold each other in orbit.
If we get whacked by this enormous golf club, it will mess up the entire universe.
But, does that matter?
Maybe - just maybe, all the planets we can see are really golf balls in a Tesco carrier bag. All waiting to be whacked.
How embarrasing - a Tesco carrier bag.
And that's the answer to Life, The Universe and Everything - and I know - for I am Slartibartfast and I designed Norway!
Especially all the twiddly bits round the edge.
Won an award for it, you know!
Good Morning.

And in march the believers of drivel... *heavy sigh*
You're not alone, man...don't let the idiots get you down.
Still, you may have some misconceptions of your own regarding black holes. Their gravity isn't "astronomically more powerful" than regular stars...at least not for your run-of-the-mill black hole. The power of their gravitational field is a direct function of their mass compared to regular stars. In addition, regular stars (and black holes)don't "pull comets [or other objects] from the middle of nowhere into its orbit." Comets coming from 'nowhere' generally follow a parabolic orbit around the star, returning to the middle of nowhere after the encounter. To actually orbit the star would require secondary encounters with planets around the star. A star (or black hole) cannot make any other object go into orbit all by itself. All of the periodic comets in our solar system have either been orbiting since the formation of the solar system, or they attained orbit through interactions with the various planets of our system (most often Jupiter).
The intense gravitational field around a black hole does not behave any differently than that of a regular star...at least not until you get VERY close, meaning thousands of miles or less, not millions. Black holes are not cosmic vacuum cleaners, they are just a big mass in a small space...and for the most part, Newton's and Kepler's laws of gravity and planetary motion apply just the same as if they were a star of equivalent mass. (Again, until you get VERY VERY close to them....much closer than the radius of the star from which they were formed.)

You forget one tiny detail about black holes. They're not just a collapsed star with a strong gravitational pull.
They've been compressed so much that they're volume continues towards 0 causing their density to skyrocket towards infinite. This is when physics, as we know it cease to exist- when dealing with the concept of infinite.
Also, black holes also have an event horizon- which is a zone surrounding it. It's the point of no return. If anything enters it, it will not come out. Ever. Not even light can escape which is another concept difficult to deal with in physics as we know it. Light being trapped? And possibly compressed?
Keeping these inmind and Einstein's theory of relative space and time (bending space and time- like all the planets sat on a mesh net and made impressions), people have theorized that because of the black hole's infinite density, it causes the mesh net of space to rip. What's beyond that is beyond our comprehension.
As for seeing a black hole, yes it is impossible to actually "see" the black hole itself and even if we could "see" it, it'll be as small, maybe smaller than an electron. Evidence of black holes are the color disks of dust and such that circle around it just beyond its event horizon.
Other evidence is the orbits of large distant celestial objects (stars, planets) around a point in space. What's at that point? A black hole.
And something about the dopplar shift also gives evidence of black holes.

One theory that cannot be confirmed nor denied is that space as we know it is a plane, or fabric. We have all seen gravity diagrams of the earth sitting on this grid of space fabric and its sinking down into it which creates its gravity. another idea is that beneath our "time" or fabric is another layer. There could be several layers. Taking a starship out to the edge of space may set you on the plane below, or above. You would continue to cruise forward with no change in pitch or yaw, save for measurements giving some strange readings.
The plane above or below would indeed be a different dimension of the exact same area of space. Same planets, same bodies. Those bodies would co-exist on every plane (lets say 3 layers of space fabric). But there could be aliens, or another species, or advanced humans on the plane below. Why?
It would be because of the vast amount of time required to travel from our spot in space, around the bend of the edge of the universe, and back to our exact spot, but on the plane below. If you think about it, Two or 3 different beings could be existing on earth. That MIGHT have something to do with sightings and supposed ghosts and whatever you want to believe in. BUT, we wouldnt know what was happening on the other plane at all, absolutely zero communication.
But.. if you had an engine that could tear a hole in space, you could pop into the other plane without the travel time. You WOULD then be in another dimension of TIME, and possibly matter. Same space physics would apply. Same fabric, just a different plane.
Most hyperspace engines in the sci-fi world, just slice a thin layer of the fabric of space up, and the ship enters its "skin". Space supposedly being indefinite, at least to us, the ship would snap into an extremely high velocity that you cannot control. Other engine ideas "jump" you from one point to another, instantaneously. The engine would punch a hole in space where you are, and where you need to go, say a 30 light year distance max, and pop, out you go.
A wormhole could be a portal to the next plane, or it may be punching through all layers of space fabric, if any. Then you would end up as nothing, or below the planes of space, which would be impossible. Everything that exists must exist on one plane or another.
Just some food for thought.

I thought you would just die if you went into a black hole. Your body would be compressed to the size of a speck of dust. That's how hard the gravity is in there.
The pull of a black hole is so strong that even light can't escape it. If you had a small black hole on a table and shined a flashlight past it, there would be no light on the other side of it from where you are.

I lived in a place we call the "sticks" and me and a friend of mine went walking in the woods one afternoon after school. We went straight down to the creek that we normally went to, but decided to go farther than normal and see where it went. We ended up at a bigger creek and to the left there was an area that to this day I swore was another dimension. It was summertime and all the trees were in full bloom, except for the square spot to our left. All the leaves and grass in that square were dead. All the trees and everything were dead. We were a little scared and decided to walk back up to my house and all at once we were completely lost. My dad was calling for us to come home we had been gone four hours in what seemed like 15 minuets time. He had to come and find us and we were nowhere near where we had come form. It was almost the freakiest thing that has happened to me in my life. My answer lies in the fact that we both seem to think all these years later that if we would have thrown something into that area, that it would have disappeared. I have since moved from that place, but sometimes wander if the square has gotten bigger?

Actually a black hole pulls in matter , so ultimately it must come out somewhere. (Possibly white holes). The point comes when time would also be effected and in theory a black hole could bend light and time so an object going through would appear somewhere else. Unfortunately the gravity would pull apart any object that went through... so its unlikely if anything could ever prove this as it wouldn't come out the other side like it went in.

I think you need to relax a little. Maybe you live too close to a black hole, and are being negatively effected by the gravitional pull.
People will believe what they believe. So, since you must favor the Big Bang theory, as well as the theory of an inflationary expansion, then what is your opinion of what the "universe" looked like before expansion?
Was it one gigantic black hole, or what?

Honestly you have to fill your heads with little bit more realistic data. Black hole can not be seen because no light is emitted or reflected from that. But its presence can be felt by observation. The presence of a very high gravity even bends light that is coming from other stars. It is not another dimension or does not take you another parallel universe and any other nonsense
