Reviews
"Scharf makes vivid the mind-boggling nature of the universe . . . [there are] bright beams of knowledge coming from this excellent book." - Wall Street Journal "To call this an absorbing read is an understatement. I felt dreamily transplanted . . . When I did emerge from the book to look up at the summer stars, the night seemed more brightly lit, slightly more known but also more awesome, more wonderfully strange." - The Barnes & Noble Review "With Gravity's Engines , Caleb Scharf establishes himself as one of the finest space storytellers." - The Christian Science Monitor "Using rich language and a brilliant command of metaphor, [Scharf] takes on some of the most intricate topics in theoretical and observational astronomical research. He weaves a wonderfully detailed tapestry of what modern astronomy is all about, from the complexities of cosmic microwave background studies to the X-ray mapping of galaxy clusters." - Nature "[H]eady stuff, but luckily for readers . . . who lack a deep understanding of cosmology, Scharf populates his book with images and colorful metaphors." - The Chronicle of Higher Education "[A]n excellent overview of the state of black hole research . . . to explain why black holes are so important, Scharf provides a tour of much of modern astronomy and cosmology along with some requisite history, an impressive feat for such a relatively short book." - Ars Technica "The subtitle of this most readable book about supermassive black holes exemplifies Scharf's playful tone...Highly recommended. Teen and adult fans of astronomy, as well as scientists looking for ways to explain black holes to nonscientists, will all enjoy this text." - Library Journal (starred review) "Scharf's explanations are vivid and accessible, evoking the awe of cosmic grandeur in a way that's as humbling as it is fascinating." - Publishers Weekly (starred review) "Scharf is a writer you'll gladly follow to the end of the universe." - Zocalo Public Square "[S]tunning. I can't remember when I last read a popular science book where I learned as much I hadn't come across before." - Popular Science Book Review (five stars) "In Gravity's Engines , 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, Director of the Hayden Planetarium at the American Museum of Natural History, author of Space Chronicles and Death by Black Hole "Superbly accessible . . . Scharf's breathtaking cosmic vision will appeal to anyone whose curiosity is aroused by gazing at a star-filled sky." - Booklist "An intelligent explanation of a weird but essential feature of the universe . . . rich, satisfying." - Kirkus "Scharf provides a virtuosic history of the universe . . . he also serves as an appealing tour guide to the eerie, infinite corridors of the cosmos in which we reside." - Prospect (UK), "Mr. Scharf makes vivid the mind-boggling nature of the universe . . .[there are] bright beams of knowledge coming from this excellent book." - Wall Street Journal "Using rich language and a brilliant command of metaphor, [Scharf] takes on some of the most intricate topics in theoretical and observational astronomical research.

Black holes are smaller than the Solar System yet project their power across the cosmos, sculpting entire galaxies of stars. They might appear esoteric and remote, but as Scharf explains, life on Earth may have been utterly impossible without them." -Marcus Chown, author of Solar System and Solar System for iPad "Caleb Scharf's fun book takes you behind the scenes of the universe itself, to see how the celestial heavyweights we call 'black holes' help shape the cosmos." -Sean Carroll, theoretical physicist at the California Institute of Technology, and author of From Eternity to Here "An intelligent explanation of a weird but essential feature of the universe . . . rich, satisfying . . ." - Kirkus, The subtitle of this most readable book about supermassive black holes exemplifies Scharf's playful tone...Highly recommended.
