Description:
Which of these bizarre phenomena, if any, can really exist in our universe? Black holes, down which anything can fall but from which nothing can return; wormholes, short spacewarps connecting regions of the cosmos; singularities, where space and time are so violently warped that time ceases to exist and space becomes a kind of foam; gravitational waves, which carry symphonic accounts of collisions of black holes billions of years ago; and time machines, for traveling backward and forward in time.
Kip Thorne, along with fellow theorists Stephen Hawking and Roger Penrose, a cadre of Russians, and earlier scientists such as Oppenheimer, Wheeler and Chandrasekhar, has been in the thick of the quest to secure answers. In this masterfully written and brilliantly informed work of scientific history and explanation, Dr. Thorne, a Nobel Prize-winning physicist and the Feynman Professor of Theoretical Physics Emeritus at Caltech, leads his readers through an elegant, always human, tapestry of interlocking themes, coming finally to a uniquely informed answer to the great question: what principles control our universe and why do physicists think they know the things they think they know? Stephen Hawking's A Brief History of Time has been one of the greatest best-sellers in publishing history. Anyone who struggled with that book will find here a more slowly paced but equally mind-stretching experience, with the added fascination of a rich historical and human component.

Awsome puppy toy
This toy is great. My baby destroys every stuffed toy we get her. Except this one and one other from the same manufacturer. She loves them so much and is constantly playing with them. No rips or holes at all. I’d give 10 stars if I could!

Durable Stuffed Toys for a Chewer
I have 2 two year old medium size mixed dogs (Paisan and Barley) Barley is a chewer and has destroyed every stuffed toy we've bought within a couple days until this sloth and racoon. I purchased the sloth almost a month ago and can't believe it's still in one piece! They love the sloth and the two of them play tug of war with it everyday. It's Barley's favorite toy to chew on and no longer has a face or squeaker (which she removed through the face) and the hands and feet have taken a beating but the rest of it has held up incredibly well due to the strong stitching. We've had the racoon for almost 3 months but for some reason neither of my dogs pays much attention to it. The ears have been chewed off but that's it. I'm so pleased to finally find toys that can hold up to Barley! They are more expensive than other stuffed toys but so much more durable and worth every penny! I'm sticking with this brand!
