The 4-million-solar-mass black hole at the center of the Milky Way. The volume of a black hole is huge. I've heard that a black hole 'belches' light and radiation whenever something falls into its event horizon. Not a moon, not a planet and not even light. (CNN) Want to know what happens after you pass through a black hole? A rotating black hole may lie at the center of our galaxy, the Milky Way. Have you ever had to vacuum your bedroom? Imagine matter packed so densely that nothing can escape. A stellar black hole (or stellar-mass black hole) is a black hole formed by the gravitational collapse of a massive star. Astronomers think the object shown in this Chandra X-ray Observatory image (in box) may be an elusive intermediate-mass black hole. Black holes are places where ordinary gravity has become so extreme that it overwhelms all other forces in the Universe. What does that mean and why does that happen? -Stellar black holes, mid-mass black holes, and supermassive black holes. With Maximilian Schell, Anthony Perkins, Robert Forster, Joseph Bottoms. A common type of black hole is the type produced by some dying stars. UNC physicist's calculations show that black holes don't exist. As they died out, they collapsed inward due to the pull of their own gravity. Black holes were once massive stars that used up all their fuel. Albert Einstein thought that a black hole--a collapsed star so dense that even light could not escape its thrall--was too preposterous a notion to be real.
