Publisher's Summary

We’ve long understood black holes to be the points at which the universe as we know it comes to an end. Often billions of times more massive than the Sun, they lurk in the inner sanctum of almost every galaxy of stars in the universe. They’re mysterious chasms so destructive and unforgiving that not even light can escape their deadly wrath.
Recent research, however, has led to a cascade of new discoveries that have revealed an entirely different side to black holes. As the astrophysicist Caleb Scharf reveals in Gravity’s Engines, these chasms in space-time don’t just vacuum up everything that comes near them; they also spit out huge beams and clouds of matter. Black holes blow bubbles.
With clarity and keen intellect, Scharf masterfully explains how these bubbles profoundly rearrange the cosmos around them. Engaging with our deepest questions about the universe, he takes us on an intimate journey through the endlessly colorful place we call our galaxy and reminds us that the Milky Way sits in a special place in the cosmic zoo - a "sweet spot" of properties. Is it coincidental that we find ourselves here at this place and time? Could there be a deeper connection between the nature of black holes and their role in the universe and the phenomenon of life? We are, after all, made of the stuff of stars.

One of the best science books for non-scientist

An amazingly written book. The author really know how to explain things well and tie it into an overriding narrative. If you have any interest in black holes and galaxy formation (and who among us doesn't!), this book is a must listen. You will become completely up to date in the subject.

Usually, I don't like it when the author does his own reading, but Mr. Scharf does an excellent job and makes the reading as exciting as the subject matter deserves.

I can't recommend this book strongly enough. He explains flawlessly. For example, he explained Einstein's gravitational equation in words in such a way that for the moment I was listening to it, I really understood what it meant. He is that good at explaining.

wonderful overview of modern astrophysics

This book is a very nice overview of modern astrophysics and in particular the role of black holes in astrophysical processes. The author is an astrophysicist / astrobiologist and knows his subject well and presents it with a kind of warmth and care that is infrequent in popular science writing. The author narrates the book himself and does a wonderful job of it. This book is a nice complement to other books such as "The 4% Universe" and "The Day We Found the Universe".
