Editorial Reviews. Review. Stephen Hawking on The Grand Design . How can we understand the world in which we find ourselves? Over twenty. Stephen Hawking and Leonard Mlodinow -- The Grand Design But that book left some The result is The Grand Design, the product of our four-year effort. Is the apparent 'grand design' of our universe evidence for a benevolent creator who The Grand Design is a book that will inform - and provoke - like no other.

Synopsis[ edit ] The book examines the history of scientific knowledge about the universe. It starts with the Ionian Greeks , who claimed that nature works by laws, and not by the will of the gods. It later presents the work of Nicolaus Copernicus , who advocated the concept that the Earth is not located in the center of the universe. The presentation has been described as easy to understand by some reviewers, but also as sometimes "impenetrable," by others. Spontaneous creation is the reason there is something rather than nothing, why the universe exists, why we exist. It is not necessary to invoke God to light the blue touch paper and set the universe going. The laws of nature that are required for life forms to exist appear in some universes by pure chance[ clarification needed ], Hawking and Mlodinow explain see Anthropic principle. Hawking is now administering the coup de grace. Carroll , writing in The Wall Street Journal , described the book as speculative but ambitious: "The important lesson of The Grand Design is not so much the particular theory being advocated but the sense that science may be able to answer the deep 'Why? If our universe arose spontaneously from nothing at all, one might predict that its total energy should be zero. And when we measure the total energy of the universe, which could have been anything, the answer turns out to be the only one consistent with this possibility. But data like this coming in from our revolutionary new tools promise to turn much of what is now metaphysics into physics. Whether God survives is anyone's guess. It gets into the deepest questions of modern cosmology without a single equation. The reader will be able to get through it without bogging down in a lot of technical detail and will, I hope, have his or her appetite whetted for books with a deeper technical content.

Because the universe was once the size of a subatomic particle itself, it's plausible that it behaved similarly during the Big Bang, Hawking wrote. That still doesn't explain away the possibility that God created that proton-size singularity, then flipped the quantum- mechanical switch that allowed it to pop.

But Hawking says science has an explanation here, too. To illustrate, he points to the physics of black holes — collapsed stars that are so dense, nothing, including light, can escape their pull. Black holes, like the universe before the Big Bang, condense into a singularity. In this ultra-packed point of mass, gravity is so strong that it distorts time as well as light and space.

Simply put, in the depths of a black hole, time does not exist.


Because the universe also began as a singularity, time itself could not have existed before the Big Bang. Hawking's answer, then, to what happened before the Big Bang is, "there was no time before the Big Bang.

As a scientist with a near-religious devotion to understanding the cosmos, Hawking sought to "know the mind of God" by learning everything he could about the self-sufficient universe around us. And who knows?

Maybe in the end the whole multiverse idea will actually turn out to be right! The Grand Design may sharpen appetites for answers to questions like 'Why is there something rather than nothing? This succinct, easily digested book could perhaps do with fewer dry, academic groaners, but Hawking and Mlodinow pack in a wealth of ideas and leave us with a clearer understanding of modern physics in all its invigorating complexity. Because everything that we call matter comes from this domain which is invisible, which is beyond space and time.

Stephen Hawking & Leonard Mlodinow The Grand Design (v 5.0)

All religious experience is based on just three basic fundamental ideas And nothing in the book invalidates any of these three ideas". A century or two hence All that is needed are the laws of nature. Our concept of time begins with the creation of the universe. Therefore if the laws of nature created the universe, these laws must have existed prior to time; that is the laws of nature would be outside of time.

Stephen Hawking

What we have then is totally non-physical laws, outside of time, creating a universe. Now that description might sound somewhat familiar.

Very much like the biblical concept of God: not physical, outside of time, able to create a universe. The spare and earnest voice that Mr. Hawking employed with such appeal in A Brief History of Time has been replaced here by one that is alternately condescending, as if he were Mr.

Rogers explaining rain clouds to toddlers, and impenetrable.

But that doesn't stop the authors from asserting that it explains the mysteries of existence In the absence of theory, though, this is nothing more than a hunch doomed — until we start watching universes come into being — to remain untested.

The lesson isn't that we face a dilemma between God and the multiverse , but that we shouldn't go off the rails at the first sign of coincidences. Cosmologists embrace these features by envisaging sweeping "meta-laws" that pervade the multiverse and spawn specific bylaws on a universe-by-universe basis.

The Grand Design

The meta-laws themselves remain unexplained — eternal, immutable transcendent entities that just happen to exist and must simply be accepted as given. In that respect the meta-laws have a similar status to an unexplained transcendent god.

But when it comes to the laws that explain the big bang, we are in murkier waters. Marcelo Gleiser , in his article "Hawking And God: An Intimate Relationship", stated that "contemplating a final theory is inconsistent with the very essence of physics, an empirical science based on the gradual collection of data.

In fact, I find it quite pretentious to imagine that we humans can achieve such a thing. Maybe Hawking should leave God alone. The book's rather conventional claim that "God is unnecessary" for explaining physics and early universe cosmology has provided a lot of publicity for the book.
