Is a white hole the opposite of a black hole?
Pretty much. While white holes are still only a theory, they are things that hypothetically allow mass and energy to escape but not enter. This is the opposite of a black hole which allows mass and energy to enter, but not to escape. Some theorize that the matter and energy escaping from the white hole may have gotten there from falling into a black hole but just missing the singularity and therefore escaping. I'm no expert on white holes, and as I said earlier they are still a theory. But from what I do know I think it is safe to say that yes, white holes are pretty much the opposite of black holes.
What is the spere surrounding a black hole is called?
The area surrounding a black hole is called the event horizon. Any object that gets caught in the event horizon will never return. All black holes have an event horizon. Black holes that have a charge and a spin, will generally have an inner horizon (coinciding to the outer horizon, the event horizon). At the inner horizon, matter is infinitely compressed and then sucked into the singularity. Along with black holes are white holes (otherwise known as "anti-black holes"). White holes are the exact opposite of a black hole, instead of sucking and trapping matter to where it is lost from the universe, white holes spew out matter and return it to the universe. Most scientists agree that white holes don't exist in our universe because they are very unstable. If the white hole was able to exist at all, it would last for only a couple of milliseconds before evaporating. The main thing between a black hole and a white hole is that a white hole is the black hole in the future. Inside the inner horizon, something bizarre happens. Matter enters one of two very narrow laser like beams. One beam goes against the black hole's spin and has positive energy and moves forward in time, but here's the real brainteaser, matter that enters the beam moving WITH the black hole's spin moves backwards in time and has negative energy. These two beams are shot out of the black hole at either end at nearly the speed of light. The black hole is basically a giant particle accelerator. Now I was correct. When the black hole shoots out the two beams, it becomes the white hole from the distant future. The two are the same. Now I know you just wanted the answer to the event horizon, but I just wanted to share a little more knowledge.
What comes after black holes?
After the black hole dies out, (see When do black holes die and/or How does a black hole get smaller) it will become just a vacuum.
What thing is in black hole?
A black hole has nothing in it and nothing can escape, not even light. Everything is just sucked in towards it where it is compressed and crushed. Nothing is in a black hole.
What has the most gravity a supernova a black hole a white dwarf or the planet earth?
a black hole has the most. Correct! The black hole as far as humans know has the most powerful gravitational pull in the universe! and is so powerful that not even light can escape it! # black hole, unless it is very small, although such a thing hasn't yet been detected. A black hole can have any mass just as long as that mass in compressed inside it Schwarzscild radius. # A supernova, which requires at least three solar masses to become a super nova in the first place. # A white dwarf # the planet earth.
Can your universe just be at the end of a black hole and can the big bang just be the birth of that black hole?
Actually one interpretation of the big bang is as a white hole, the inverse of a black hole.

What happens if a white hole gets sucked into a black hole?
A white hole (assuming they actually exist) is simply a small black hole, so nothing very spectacular would happen. The black hole would just get very slightly more massive (well, considerably more massive on a "how many ounces is that" scale; not so much on a "how many solar masses is that" scale).
If there are black holes does that also mean that there are white holes scientifically?
No, it does not mean that.Black holes and white holes are two different "solutions" of the equations of General Relativity; but that doesn't imply that one, or the other, actually exist. It is now almost certain that black holes exist; as for white holes, there are theoretical problems that may make them impossible, such as: * A white hole is, in many aspects, there reverse of a black hole. And just as there is no way to destroy a black hole, there is no way to CREATE a white hole. * It seems that in a white hole, entropy would decrease over time.
What would happen after getting sucked in a black hole?
Their is not more info about this because there are no evidences of humans being sucked into black hole but once sucked in, the object which has been sucked in will not be able to escape out from black hole's event horizon as a black hole very very very very very strong gravitational field. But some scientists say that object which went into the black hole comes out through a white hole (which is just the opposite of black holes in all aspects)

Can white holes only be entered by the outside?
Not much is known about white holes - specifically, it isn't know whether they even exist, or whether they even can exist. However, the ideas is that, just as nothing can EXIT a BLACK HOLE, similarly, nothing can ENTER a WHITE HOLE. (This would make it unlikely for a white hole ever to form.)
What part is the white of the eye?
The white part of the eye is the sclera, the colored part is the Iris, and the 'black dot' (which is actually just a hole reaching the back of the eye) is the pupil
Where does all the stuff from the black hole go?
A black hole isn't a tunnel to somewhere else. It just does to the center of the black hole, and is crushed into a little speck.
What comes after black holes?
After the black hole dies out, (see When do black holes die and/or How does a black hole get smaller) it will become just a vacuum.
Can a black hole travel?
Yes. A black hole can move just like anything else with mass.
