Exploring Black Holes

Audisee® eBooks with Audio combine professional narration and text highlighting for an engaging read aloud experience! What space objects can have millions of times more mass than our Sun, but they remain invisible? Black holes! Their gravity is so strong that not even light can escape. In this book, you'll learn about one of the amazing wonders of space. As part of the Searchlight BooksTM collection, this series explores outer space and sheds light on the question What's Amazing about Space? Fantastic photos, kid-friendly explanations of science concepts, and useful diagrams will help you discover the answers!

Explore the cutting-edge science of black hole research and discover fascinating interviews with respected scientists in the field.

"The metric helps to answer every scientific question about (nonquantum) features of spacetime surrounding a black hole, every possible question about trajectories of light and satellites around the black hole as well as around more familiar centers of attraction such as Earth and Sun. The metric for a rotating black hole may tell us about quasars, the most powerful steady energy sources in the Universe. The black-hole metric brings preliminary insights about the history and structure of the Cosmos." "Using the metric requires only algebra, elementary differential calculus, and a handful of integrals. This modest mathematics opens the subject to the interested person and paves the way to a deeper study of general relativity for one who will discover new truth about this strange and beautiful Universe, our home."--BOOK JACKET.

What happens when something is sucked into a black hole? Does it disappear? Three decades ago, a young physicist named Stephen Hawking claimed it did-and in doing so put at risk everything we know about physics and the fundamental laws of the universe. Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics. THE BLACK HOLE WAR is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality-effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space. A brilliant book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes, Leonard Susskind's account of the Black Hole War is mind-bending and exhilarating reading.

Tracing the evolution of humankind's pursuit of astronomical knowledge, this resource looks deep into the furthest reaches of space. Children will follow along as the realization that the Earth is not at the center of the universe leads all the way up to recent telescopic proof of planets orbiting stars outside the solar system. In addition to its engaging history, this book contains 21 hands-on projects to further explore the subjects discussed. Readers will build a three-dimensional representation of the constellation Orion, see how the universe expands using an inflating balloon, and construct a reflecting telescope out of a makeup mirror and a magnifying glass. It also includes small biographies of famous astronomers, a time line of major scientific discoveries, a glossary of technical terms, and dozens of full-color images taken by the Hubble Space Telescope and the Chandra X-Ray Observatory.
