black holes (astronomy)

"Welcome, Agent 359. This file is full of top-secret information about black holes. Learn the basics of how black holes form, their different sizes, and how they were found. Then, discover what scientists are learning about them now. What will you do with our new knowledge? Good luck and remember these are top secret space files!"--.

"[The author] discusses uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. He reveals the mind of a scientist at work . . . [as he] traces the ongoing adventure of his own cutting-edge research, investigating whether all black holes could eventually turn into white holes, equally compact objects in which the arrow of time is reversed. Guiding us beyond the horizon, he invites us to experience the fever and the disquiet of science--and the strange and startling life of a white hole"--Provided by publisher.

"Historical photographs combined with . . . narration bring the story of the first photograph of a black hole to life. Kids will learn why it was so hard to take a photo of something so dark it does not reflect light, and so far away it could barely be reached. Primary source quotations bring the . . . accomplishment to life"--Provided by publisher.

"After introducing the basics of the special and general theories of relativity, this book describes black holes bothas astrophysical objects and theoretical 'laboratories' in which physicists can test their understanding of gravitational, quantum, and thermal physics"--Publisher.

"There once was a little black hole who loved her universe, and especially her friends: the stars and the planets, the space rocks and the space fox, even the flying astronauts. She loved to play and laugh with them as they soared through the galaxy. That is, until they disappeared--which was always what happened. The little black hole felt all alone. But when she meets a big black hole and shares her worries, the big black hole knows just how to help! And the little black hole finds out that she has the power to find her friends, wherever she goes"--Provided by publisher.

"In this book, meet a black hole and learn what makes them special. Through simple sentences, emerging readers will learn technical facts and develop word recognition and reading skills"--Provided by publisher.

"Black holes are neither holes nor black. In fact, they're invisible and packed with matter! Future astronomers will find out many more fascinating facts about these space phenomena in this intriguing book. Carefully crafted text breaks down the most important information about black holes, such as how scientists locate them and their significance in a star's life cycle. Amazing photographs support critical concepts and inspire a true appreciation of the spectacles of space!"--.

Introduces black holes, describing their physical features, how they were discovered, what causes them, and where they exist in space.

"Jordie loves space. She can't believe it when she finds a black hole in her desk. But when the black hole starts snarfing everything in sight--including her dog--she realizes the black hole needs to go home. "--.
