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.
Stephen’s answers to six of the questions are deeply rooted in his science. (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?). Here you will find him discussing in depth the issues that I’ve described briefly in this Introduction, and also much, much more.
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.
