Not sure if this is the right section to post about this topic, but I've just been really curious about black holes. Where would you end up if you went through a black hole? Do you think there is another galaxy when you go through a black hole??? Does time change in a black hole????? Also, someone asked me this question, but if nothing travels faster than light, how does a black hole pull light inside of it?

What do you guys think??? Would be nice to hear other peoples thoughts on black holes! =P

And how come we never see black holes....or how do we even know they exist....?

Almost comical, if you've ever taken 6th grade science you'd know this.
Black holes are an opening in space itself, caused when an object of great mass causes a rupture (like a star going supernovae). Nobody knows what would happen if someone went through a black hole, because they would be dead. To put in perspective, you'd be stretched out to about the thickness of a sheet of paper. However, there are a set of opposite occurrences, known as white holes, that shoot out matter.
To answer your questions directly, time doesn't exist in a black hole. There are no physics, time, light, anything. As for the light thing, its not about speed, its about direction. Black holes have an infinite pull of gravity, and light has a finite speed. Anything with an infinite pull will inevitably take what has finite properties.
We don't need to necessarily see black holes to know they're there. In all reality, we have no proof. The concept of a black hole is all theoretical since we technically can't prove it. Usually scientists determine where they are when light is obscured, because the hole will pull the light around it inside. There are far more than we know of, because we can't see them all.

No one has a clue what happens in a Black hole.It could be a giant Cannoli riding a dung beetle's monocle for all anybody knows.

Because we can measure a black hole's gravitational pull, the gravity of a black hole is so massive that even light doesn't escape, the milky way rotates around a black hole.

Well, black holes exist, but no equation invented yet can explain it fully, there have been a couple of theories from known scientists like Stephen Hawking that have tried explaining these black holes, but they are all theoretical and can't be tested..

In theory.. You would be ripped apart by the gravity and the density of an black hole.

Can you travel through a black hole? I think you got this mistaken by a worm hole, which in itself is a theory as well -.- And if "in theory" you would want to make a worm hole, you would need the energy output of a black hole to even be able to do that, so that's rather difficult.

Does time change? Well, time is relative yo.

Black holes are awesome and scary, don't want touch one with a 10 billion miles pole.

If you went through a black hole, you would be stretched along infinity until you no longer exist.

I remember watching a great video on Youtube that explained what would happen if you went through a black hole. I will look for it and come back if I find it.

1. The other side.
2. At the time I'd have bigger worries, like dying, or why I was so close to a black hole. There's more than one galaxy though, so uh, yeah, there's always another galaxy different from the one you're in, when you go through a black hole, assuming of course, you go through a black hole. It still holds when you don't go through a black hole too.
3. Time? Oh, time. Yes, and it changes into a moose. Black holes are full of moose.
4. With gravity.

In all seriousness though, if you really want to know about black holes you should brush up on your physics. Read lots of physics.

You can also read this.
http://en.wikipedia.org/wiki/Black_hole

Oh, we don't see black holes because light can't escape the gravitational pull and we know they're there because we don't see them. They can be used to magnify objects.
Edit: a moose, not an moose.

While the majority of your post is correct I cant really stand one thing that I have to point out: "The concept of a black hole is all theoretical since we technically can't prove it. " applying that logic we cannot prove anything. That'd be because black holes are about as proven and verifiable as the "theory" of gravity. They're quite well established.

As for the OP, I really suggest you take college astronomy if these things interest you. I can say my college astronomy courses were some of the most exciting learning I've had in college thus far and I'm two years past most of those science courses now. If you'd like some direct answers I'm sure you can just youtube around for some videos by Neil deGrasse Tyson. Him and Lawrence Krauss have given many "generalized" or understandable talks on issues that involve things like black holes for those uneducated in the field. There is a commonly quoted colleague of Richard Dawkins who has a particular way in which he'd wan't to die in relation to black holes. You can find that here:

http://www.youtube.com/watch?v=JXEiKPxCSdA&t=1m27s
Explination of the quote lasts from the time linked until 2:50.

Amazing things :)

To the above poster: You really do an injustice to science posting something silly to an inquisitive person Wikipedia is about as fun to learn science as a boring lecture. There are many other means to which a person can become very well versed in the realm of science in fun and exciting ways. Youtube can be used for more than just degrading your mind with useless entertainment!

Most of your answer is... questionably correct to be honest, so maybe you should check your facts before saying its comical.

Where is this 'opening' in space? It doesnt exist, its a singularity, not an opening.

Black holes are irrelevant of mass its density thats important

White holes are predicted but never observed, quasars are what you may be getting confused with which dont generate mass and shoot out. They simply accelerate orbiting mass.

Black holes only have 'infinite gravity' at the singularity where as light cannot escape from a finite distance from the singularity, so the infinite gravitation is nothing to do with light escaping, more over you cannot be so naive when dealing with wave properties, especially null like waves.

The idea of having no proof of blackholes is identical to having no proof that the sun really exists, sure we can see its effects all over the place and measure them, but how do you actually see it. All we see is the indirect effect of fusion, right? Its a dumb point to say the least.

I just saw a special on the Science Channel titled Swallowed by a black hole. There is a star or a large gas cloud heading towards the Galactic Center. Scientist are eagerly awaiting the outcome. It will be the first time humans have actually seen (up to the event horizon) what happens when an object encounters a Black Hole. You may also want to check out TV shows such as The Universe, How The Universe Works and how the Solar System Works on History and the Science Channel. Lots of good info and very entertaining. I'm sure there are eps uploaded on Youtube. Enjoy your journey.

Portals to other dimensions, where you get crushed down to the size of a pinhead.

Lol

You die the end.

And you end up on the other side? What? Lol it's not a white hole it rips you to pieces the end.

Well, what we do know is this:

Black holes are a cosmic rift, or "tear" in the space and time mesh, and are created when a star creates the element iron, and cannot fuse it with another element, causing the star to burn all of its energy, and causing it to collapse within itself.

Because black holes can suck in light, they also suck in time. When something is being sucked into a black hole ( and becoming speghettified) from a third person view ( such as scientists watching the event occur) the object will never pass over the event horizon, because as we see it, time has completely stopped for that object. So, we will see it infinitely remain at the edge of a black hole, while in actuality, it has already got sucked in.

Black holes also expel Beams of energy occasionally, which is to believed to be the destroyed mass that got such in. These beams of energy are reffered to as Gamma Ray Bursts. Hypernova' also expel these Gamma Ray bursts.
