Its hard to believe that a whole book can be written be a handheld keyboard like communicator solely with the help of your fingers (and your brain of course) but Steven Hawking has done it. Lecturer in oxford, or in some other university, he is on the same position as Isaac Newton. In the line of great physicists, Hawking is the latest after Einstein, Newton and Galileo.
The main objective in the book is the unification of physics, that is, to find a unified force. There are 4 fundamental forces: electromagnetic, weak, strong, and gravity. electromagnetic and strong have been unified, a unification of electromagnetic, weak, and strong is on its way, but unifying gravity is tricky. The book is based on finding the universal theory that could predict everything.
Gravity, Relativity and Quantum theory all fail in one situation or another.
The book goes on telling about singularities and about the speculation that the universe might have started with it. Singularity is a point of zero volume and infinite density.
Space-time is clearly and distinctively explained in chapter 2. The different ways in which time travels, the arrows of time, are also explain.
On the whole the book is totally AWESOME. It's you can get to take a dive into the world of theoretical physics. If you're not an astro-buff, this book will make you one!
