’’A universe that is finite in size but did not begin with a singularity is the result of one attempt to combine aspects of general relativity and quantum mechanics. The history of this no-boundary universe in imaginary time is like the surface of Earth, with the Big Bang equivalent to Earth’s North Pole and the size of the universe increasing with imaginary time as you head south toward the equator.’’
the above paragraph depicts the ambiguity, the 4D universe and the sheer vastness of space.this paragraph is the original one as told by dr.Stephan Hawking.
the book guides the reader through a whole variety of timezones and in fact gives ’a brief history of time’.the book has been very expertly written .it provides an insight to the world of astronomy at a very steady pace that can be understood by anyone of any age.But , i think only an imaginative person who has some interest to know the origin of the universe can only enjoy this book...like me. I don’t want to discourage any of you reading this review but it is the truth.other than this the book is great and offers a whole new dimension to your way of thinking..happy reading...
the paragraph at the beginning is just a jist of what is in store...
