In the twenty-first century, sophisticated technologies are bringing us closer to seeing black holes in action. Meet the scientists who first thought of black holes hundreds of years ago, and learn about contemporary astrophysicists whose work is radically shaping how we understand black holes, our universe, and how it originated."--Amazon.
