Black holes and baby universes and other essays

Written by Stephen Hawking. This book comprises of a wonderful collection of Scientific Essays and Interviews with Stephen Hawking. It also has a few autobiographical notes in it, which describe his childhood, his Motor Neuron Disease, and many more things. Although this book is appreciable, I did not understand any more than half of the whole book, as it contained stuff about Black Holes, Galaxies, etc. which was very difficult to understand. Hawking states that Black Holes are not Completely Black, proving it with a research that showed Black Holes emit a radiation. He even stated that as there are Black Holes, which absorb but never release particles; there are also White Holes, which are vise-versa. Reading this book was not enjoyable a lot, because it could not be understood. But it is really worth buying.
