For this book the relevant question is: What is the universe and why? So far scientists engaged in this field of investigation occupied themselves seriously with the answering of the what part of the question and have just started to answer the why part, which should normally engage the philosophers. But the latter, barring a few, are not fully equipped to go deep into the what part revealed by the scientists. The gap has to be filled up. The author has taken courage to bring the what and why parts in one comprehensive volume, and try to answer both. In fact modern science and philosophy are perhaps talking about the same thing but in different languages. The attempt to bridge the language gap is what is most important.
