PIECE OF GARBAGE
I bought this book out of curiosity, because I am in interested in virtually everything that has to do with the Ligo facility and the other gravity wave detectors throughout the world. What a great disappointment. The author starts his book clamimig that gravity waves are no ripples in spacetime at all, but they are just like electromagnetic waves, waves that propagate THROUGH spacetime. Well, now this book rests where it belongs, in my trash can. As Einstein would say: Das ist absolut Blödsinn" (This is TOTAL NONSENSE...).Stay away from this book. If it was a total waste of money.
