it was amazing

Aside from those with an extreme interest in astronomy, most people fall into the category who consider the science of the sun, moon, planets, stars and the surrounding universe mildly interesting, if often overwhelming. That is what makes A Black Hole Is NOT a Hole all the more successful. Though it is written at a level for older children to understand, this is an excellent introduction to deep space concepts for people of all ages.

Big scientific concepts such as matter, mind-boggling distance (light-years!), and perhaps the biggest of them all, gravity, are given ample, clear explanation. The existence of black holes has been difficult to prove since their discovery, and what could become overwhelming astrophysics is distilled as simply as possible. That Einstein never fully accepted the concept of black holes in his lifetime shows how far science has come in recent decades. Artist depictions and telescopic images fill the book with pictures that do their best to make the unimaginable come to life. Facts are engaging and well-explained, such as the outer limit of a black hole is called the Event Horizon; from this point, no matter can escape the pull within. And our own galaxy has black holes, the largest of which makes up the center of the Milky Way in the constellation Sagittarius!

An extremely useful glossary and websites to further explore round out this brilliant informational book that will open the eyes of readers who will learn how a black hole is not quite a hole, or at least not a hole in the way that we on Earth know holes. And as the author often states, science is a moving target, and each day researchers are learning more about the darkest dark of our universe.
