Remember, black holes may be portals, or doors, or anything (as Ancient mentioned). This is not well understood by scientists yet though. It may be true that wormholes don't exist at all. It has also been suggested that black holes are the birthplaces of other universes. Thats what I like to believe, because it would explain why the forces of gravity, electromagnetism, etc, have the strengths they do in our universe, which are compatible with the evolution of life in the universe. Afterall according to our current knowledge the material of black holes eventually evaporates by a process called Hawking radiation (after Stephen Hawking). Its kinda crazy. We know this because in quantum mechanics, energy may always be borrowed from the vacuum, but it must be repaid quickly. So this means that matter can be vaccumed up or regurgitated. So basically the greater the amount borrowed, the quicker it must be repaid. No light of any kind, including X-rays, can escape from inside the event horizon of a black hole. Some black holes have a mass greater than a few billion solar masses, which is almost incomprehensible. Common sense would say, that the mass is obviously going somewhere else. Yet, no matter is created nor destroyed, it just changes in form. Anyway, the ultimate answer to your question danman2_2999 is we don't know currently. We don't know because we can't perceive anything that escapes. Why? because when material enters a black hole it doesn't disappear, but it will no longer be visible to an outside observer, because light cannot escape beyond the event horizon of the black hole. Anyway, we can be thankful that there is no danger of the Earth (located 25,000 light years away from the Milky Way's black hole) being pulled in. Hope that helps.
