A black hole is a point where gravity has collapsed in on itself and is so strong that even light cannot escape it. A black hole does not have a bottom because it is not really a hole. It is called a black hole because when it is seen... it looks like a black hole with no light coming out of it. It looks like a hole in space when looked at with a telescope.

In a way, they have a "bottom" but not the way a hole in the ground has one. Black holes are spherical, like the earth or sun, so the "bottom" would actually be the center of the globe.
They are hyperdimensional objects, that is they don't fit into the human concept of 3-D, they are more than that. The best way to imagine what this thing "looks" like is to think of a big funnel that points the wide end at you no matter how you move around it. The narrow point of the funnel is the bottom of the black hole.
The real question to ask is how does gravity escape the black hole when light can't.....But I can't share that answer just yet!

I'm no Physicist. However the answer as I understand the question is yes-simply stated. At the bottom of the black hole you will find a singularity. That is the most densly compacted remains of a huge star at least, I believe, 10 solar masses or more. It is a place where gravity is described to have gone mad. The best analogy I can come up with is to be able to derive an answer for the function of 1 divided by 0. In other words N=1/0. Black holes are generally found in the center of most galaxies and range from multiples of solar mass to hundreds or millions of solar masses. Their size/mass is determined by what stellar matter has been consumed by the black hole. I will defer further attempts to describe a black hole to the holder of the Newton Chair in Physics at Cambridge, the most respected, Dr. Stephen Hawking.

A black hole is not a hole in the ground. A hole in your shirt doesn't have a bottom.
Then again... a black hole isn't really a hole. It's a collapsed star who's gravity is so intense, nothing (including light) can escape ...
So... does it have a bottom? Well... I'M sure as hell not going to find out.

The term black hole dates back to before our understanding of what we think a BH is today. There are two working theories on a BH. One that it is an incredible distortion of Space and time and that it leads somewhere. Personally I think that this is a fantastical belief on marginally based on science. The second is that it is a incredible distortion of Space and time and no one really knows beyond theories. This is hitting on the raw edge of Science. One thing that is certain that how you and I understand things on earth (well outside of a BH) is very different from what things are like in one. If there is a bottom, I would put my money on the fact that there probably is. If it is bottomless or connects with something else, no one can say, as no one has been there yet.

No. The other end of a black hole is a white hole which spews matter into an alternate Universe. In other words, each black hole in this Universe is a big bang in another.

Many scientists believe that a black hole is a star that has died and then collapsed in on itself creating a highly concentrated gravitational field. In that case the "bottom" of the black hole would be a super densely compacted rock that used to be that star.

This question is currently labelled useless. What do you expect us to do?
1. The nearest black hole is 1600 light years away, our farthest man-made object is only half a light-day away from us.
2. Anything that falls into a black hole cannot be revived, and nothing can escape it to tell us what happens to it.

A black hole is a concentration of mass (known as a singularity - a region with infinite mass and infinite density), the gravitational field of which is so strong that its escape velocity exceeds the speed of light. The point in space at which this occurs is known as the event horizon. It is beleived that the laws of space-time no longer hold valid for these conditions. It is beleived that there is no 'end' to a black hole, simply a point of matter. Recent theories suggest that black-holes may radiate 'hawking-rays' at right angles to the plane of the rotation of the singularity.
I think you may be refering to the phenomenon of a 'worm-hole', a short cut in space and time. In theory one could emerge at any point in space and/or time, in fact you would exit the wormhole before you entered it due to the speed of travel. is this proof of fate? :)
Hope this helps

They have a centre, a big squash of all the planets that got sucked in when the star exploded, and then colapsed on itself. But i dont know if you would class the centre as the bottom... they are kind of like a ball, and you look at them from above, and from whatever side you look at them you will hit something but it isnt necesarily the bottom
