What are black holes? How do we know they're there if we can't see them? You've heard the gossip about what these things can do---now get sucked in by the truth! Learn about their gravitational pull, how far away the nearest one is, why even light can't escape, what creates them, how we can identify where they are, and the history of their discovery. Plenty of thought experiments, photographic examples, illustrations and sidebars are included to make this complex theory simple enough for elementary-aged students to understand. Encourage young star gazers and physicists with this comprehensive look at a fascinating phenomenon! 74 pages with index, glossary, and author's note. Hardcover with dust jacket. Origins are not mentioned, but there are two mentions of "millions" and "billions" of years, only one of which refers to the past, rather than a lifespan of a star.
What is a black hole? Where do they come from? How were they discovered? Can we visit one? Carolyn Cinami DeCristofano takes readers on a ride through the galaxies (ours, and others), answering these questions and many more about the phenomenon known as a black hole.
In lively and often humorous text, the book starts off with a thorough explanation of gravity and the role it plays in the formation of black holes. Paintings by Michael Carroll, coupled with real telescopic images, help readers visualize the facts and ideas presented in the text, such as how light bends, and what a supernova looks like.
A BLACK HOLE IS NOT A HOLE is an excellent introduction to an extremely complex scientific concept. Back matter includes a timeline which sums up important findings discussed throughout, while the glossary and index provide a quick point of reference for readers. Children and adults alike will learn a ton of spacey facts in this far-out book that’s sure to excite even the youngest of astrophiles.
Carolyn Cinami DeCristofano is the author of LEONARDO'S ABC, as well as the acclaimed nonfiction middle grade read, A BLACK HOLE IS NOT A HOLE. Aside from writing for children, Carolyn is also science educator and principal consultant with Blue Heron STEM Education. She lives in Boston, Massachusetts.
