THE GOLDILOCKS ENIGMA

Sinopsis de THE GOLDILOCKS ENIGMA

In his latest book Paul Davies explores rather than definitively answers the deep questions of existance. Why are we here? Why is the universe fine tuned for life and what relationship does consciousness have to the universe at large? The reader is taken on a truly cosmic tour of physics in the attempt to answer some of these fascinating questions.The first part of the book seeks to explain why the universe possesses certain characteristics and explores various theories such as inflation theory, the big bang,quantum fluctuations and the four fundamental forces,gravitation,electromagnetism,and the weak and strong nuclear forces. He then explains how physicist are seeking to unify these forces of nature into one Grand unified Theory which leads onto String theory and its further development M theory. At this point the reader will feel that they have left the familiar world of common sense. Davies explores the implications of String theory and M theory which posits a number of unobserved dimensions. This eventually leads to the idea that we are living in a multiverse, the concept that trillions of other universes exist and this is why we are so fortuitous in this one.We have won the cosmic lottery and although our universe is fit for life, trillions of others are sterile. If this mind blowing idea is not enough, the possibility is also explored that we are living in a fake universe. An infinity of other universes greatly increases the chances that an intellect could have evolved way beyond anything that we could possibly comprehend. Further it is argued this intellect could have the capability to simulate a universe,ideas that were explored in the film The Matrix. Davies quotes the cosmologist Martin Rees at this point who states.
