In this engrossing work, astrophysicist Levin (Black Hole Blues and Other Songs from Outer Space) delves into the world of black holes, one of the most incomprehensible phenomena in the universe. As noted by Levin, black holes do not consist of atoms, light, or particles; rather, they are a warp in spacetime. Their existence was not even accepted by a large number of scientists throughout much of the 20th century, but today they are essential to understanding the structure of the cosmos. They are numerous and incredibly dense; for example, a black hole a mere six kilometers across would have the same mass as the sun. They are so strong that light cannot escape them. They will also play a key role in the end of the universe, as eventually, the sun and the rest of the matter in the universe will fall into a black hole. Levin describes the subject matter in an accessible writing style that is both entertaining and poetic. She even describes what would happen to the courageous individual willing to be absorbed by a black hole.
VERDICT Recommended for nonscientists and those seeking to understand the cosmos better.
