Einstein's Monsters by Chris ImpeyBlack holes are the best-known and least-understood objects in the universe. In "Einstein's Monsters", distinguished astronomer Chris Impey takes readers on a vivid tour of these enigmatic giants. He weaves a fascinating tale out of the fiendishly complex math of black holes and the colorful history of their discovery. Impey blends this history with a poignant account of the phenomena scientist have witnessed while observing black holes: stars swarming like bees around the center of our galaxy; black holes performing gravitational waltzes with visible stars; the cymbal clash of two black holes colliding, releasing ripples in space-time. Clear, compelling, and profound, "Einstein's Monsters" reveals how our comprehension of black holes is intrinsically linked to how we make sense of the universe and our place within it.
