A black hole contains a large amount of matter, compressed in an incredibly small space.
We do not actually know what is happening within a black hole. It is clear that the currently accepted theories of Physics cannot explain what exists within the Schwartzchild radius of a black hole (and the Schwartzchild radius, or event horizon, is much larger than a point). There are some interesting new theories, but it unlikely that we will soon be able to place instruments near enough to a black hole to test these theories. Once the Large Hadron Collider at CERN is up and running, it may give us some data which will help to test these new theories.
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
There isn't an exact opposite of a black hole in terms of cosmic phenomena. Some theories suggest the existence of "white holes," which are hypothetical regions of spacetime where matter and energy are ejected instead of being pulled in, mirroring the behavior of black holes. However, white holes are purely theoretical and have not been observed or confirmed.

* Nothing can survive a black hole. Some people think if you put 1 million objects in a black hole, they survive the event horizon(edge of black hole) but only one survives the singularity(the point where the othere 999,999 are crushed into atoms).
Because the physics within a black hole is so extreme, current theories can't really describe in detail what goes inside a black hole, especially near the singularity.

There is many theories that exist about that. I will tell you some these theories. I'll start with the one that looks the most truthful. 1-Earth may be torn into pieces because of the black holes gravity. Then, these piece will be torn into molecules. Then these molecules will be torn into atoms. (you get the idea) 2-There is a theory that all the matter that enters in a black hole is "teleported" to another region of space. I will explain that more in details. 1- Earth enters in the black hole. 2-It gets in a inter-dimensional tunnel called "wormhole". 3- It exits from a white hole, in another region of space. 3-There is a theory that when you enter in a black hole, you are "teleported" into a different universe.
The discovery of black holes was not due to a single person; several people participated, and at first, it was all very theoretical. You can find some of the history behind the theories and discoveries in the Wikipedia article on "Black hole".
No, but some stars end their life by becoming a black hole.
Gravity. This a known and to some extent an arguably proven fact. But there are also theories that Black holes contain Anti-matter, an entity in inverse existence to "matter".

Not all galaxies have a black hole at their center. Some galaxies, like our own Milky Way, do have a supermassive black hole at their center, while others do not.
Some stars become a black hole or a black dwarf.
it makes some of us ask ourself a question like what if there is another dimension or worlds all around us we just cant grasp the tip of evolution and alternate realities such as if u where to go in a black hole you would probly not be able to come back from wherever or watever happened to you. a black hole has uncontrolable gravitational pull that means if u went directly in the middle of it then you would be torn in each equal direction of the black hole. but if u where to enter that black hole with proportional mass and proportional density then who knows what would happen....
