(One of New Scientist's Top 10 Books to Read in 2012) This fascinating glimpse into the depths of black holes presents new evidence that they don't just vacuum up everything that comes near them; they also spit out huge beams of radiation and clouds of matter. Black holes, it turns out, blow bubbles, says Caleb Scharf. The director of the Columbia Astrobiology Center and author of the "Life, Unbounded" blog for Scientific American, Scharf explains here how these bubbles profoundly affect the cosmos in their vicinity.
"Caleb Scharf deftly tells you all you wanted to know about black holes, as well as all you never knew you wanted to know. By the end of the book your conclusion will surely match mine: black holes are terrifying yet awesome constituents of the cosmos."—Neil deGrasse Tyson
"Scharf adds a new insight to the half-century-old idea that most atoms in our bodies were born in exploding stars. He argues that some of those hydrogen atoms were likely touched by radiation from black holes—without which we wouldn't be here."—New Scientist
