Translated into thirty languages, it has sold ove Stephen Hawking, the Lucasian Professor of Mathematics at Cambridge University, is widely regarded as one of the most br A Note from the Publisher. Stephen Hawking was regularly asked for his thoughts on the "big questions" of the day by scientists, tech entrepreneurs, senior business figures, political leaders and the general public.
THE NO. This was the beginning of gravitational-wave astronomy. Our team had achieved, for gravitational waves, what Galileo achieved for electromagnetic waves. During our glorious year of —5, while I was dithering over gravitational waves, and Stephen was leading our merged group in black hole research, Stephen himself had an insight even more radical than his discovery of Hawking radiation.
He gave a compelling, almost airtight proof that, when a black hole forms and then subsequently evaporates away completely by emitting radiation, the information that went into the black hole cannot come back out. Information is inevitably lost. This is radical because the laws of quantum physics insist unequivocally that information can never get totally lost. So, if Stephen was right, black holes violate a most fundamental quantum mechanical law.
How could this be? The great majority of theoretical physicists find this conclusion abhorrent. They are highly sceptical. And so, for forty-four years they have struggled with this so-called information-loss paradox. It is a struggle well worth the effort and anguish that have gone into it, since this paradox is a powerful key for understanding the quantum gravity laws.
Stephen did not prove that the information escapes, so the struggle continues. Hawking gave us questions. When ultimately we master the quantum gravity laws, and comprehend fully the birth of our universe, it may largely be by standing on the shoulders of Hawking.
I have shied away from big questions. Stephen, by contrast, was always attracted to big questions, whether they were deeply rooted in his science or not. He did have the necessary skills, wisdom and self-confidence. This book is a compilation of his answers to the big questions, answers on which he was still working at the time of his death. Is there a God? How did it all begin? Can we predict the future? What is inside a black hole? Is time travel possible?
How do we shape the future? His answers to the other four big questions cannot possibly be rooted solidly in his science. Will we survive on Earth? Is there other intelligent life in the universe? Should we colonise space?
Will artificial intelligence outsmart us? Nevertheless, his answers display deep wisdom and creativity, as we should expect. Do you like this book? Please share with your friends, let's read it!!

He educated millions of readers about the origins of the universe and the nature of black holes, and inspired millions more by defying a terrifying early prognosis of ALS, which originally gave him only two years to live.
In later life he could communicate only by using a few facial muscles, but he continued to advance his field and serve as a revered voice on social and humanitarian issues. Hawking not only unraveled some of the universe's greatest mysteries but also believed science could be used to fix problems here on Earth.
Now, as we face immense challenges on our planet--from climate change to the development of artificial intelligence--he turns his attention to the most urgent issues facing us.
