This little book describes the past, present and future of black holes through a funny and engaging story involving Grandpa Louie, his two grandchildren and two of their friends.During a beautiful sunny day on the beach, the children play, swim, enjoy their time, and ask a lot of questions to Grandpa Louie, a retired astronomy professor. Who better than him to tell all the secrets of black holes to a group of curious children? Who discovered them? What do 'black holes' mean? Are There different types of black holes? How does a black hole form? What is his fate? How did scientists manage to 'observe' these celestial bodies which, by definition, cannot be seen? At the end, we also bring up the subject of parallel universes, which could exist beyond the horizon of a black hole.This book is suitable for children from 6 to 12 years old.

What is a black hole? What is dark matter and what is it made of? How do scientists discover black holes and dark matter if they can't be seen? What do scientists know about these mysterious parts of the universe and what do they still hope to find out? Budding astronomers will learn the answers to these questions and more!

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

Explores the phenomenon of black holes, explains why astronomers think they exist, what causes them, what they are like inside, and the search to find black holes in space.

If scientists can’t touch the Sun, how do they know what it’s made of? And if we can’t see black holes, how can we be confident they exist? Gravitational physicist David Garfinkle and his brother, science fiction writer Richard Garfinkle, tackle these questions and more in Three Steps to the Universe, a tour through some of the most complex phenomena in the cosmos and an accessible exploration of how scientists acquire knowledge about the universe through observation, indirect detection, and theory. The authors begin by inviting readers to step away from the Earth and reconsider our Sun. What we can directly observe of this star is limited to its surface, but with the advent of telescopes and spectroscopy, scientists know more than ever about its physical characteristics, origins, and projected lifetime. From the Sun, the authors journey further out into space to explore black holes. The Garfinkle brothers explain that our understanding of these astronomical oddities began in theory, and growing mathematical and physical evidence has unexpectedly supported it. From black holes, the authors lead us further into the unknown, to the dark matter and energy that pervade our universe, where science teeters on the edge of theory and discovery. Returning from the depths of space, the final section of the book brings the reader back down to Earth for a final look at the practice of science, ending with a practical guide to discerning real science from pseudoscience among the cacophony of print and online scientific sources. Three Steps to the Universe will reward anyone interested in learning more about the universe around us and shows how scientists uncover its mysteries.
