National Geographic : Monster Black Holes (2009)
Travel to the edge of space and beyond to discover nature's ultimate abyss—black holes. Explore where they are found, how they begin, and how it may be possible to harness and use the power they produce. In Monster Black Holes, scientists steadily piece together the complex dynamics of a black hole's birth and also examine the growth of a select few black holes to super massive proportions that dominate the centers of galaxies. As a monster black hole swallows everything in its path, it generates energy that shapes the universe around it in powerful ways. Journey into the heart of a black hole and explore what happens to matter when it comes too close, and whether our Milky Way galaxy will one day come to an end when the black hole at the galaxy's center explodes.
