PONDER THE UNIVERSE'S GREATEST UNANSWERED QUESTIONS

A little book of big questions, posed by "the world's finest minds" (The Guardian): in The Last Unknowns, Jared Diamond, Steven Pinker, Elaine Pagels, Nobel laureate Richard Thaler, Booker Prize-winner Ian McEwan, Harvard physicist Lisa Randall, and more than 200 other leading thinkers reveal the universe's greatest unanswered questions.

This is a book of questions-only questions. In these pages are the universe's last and greatest unknowns. Here are the riddles that have fascinated, perplexed, and obsessed today's greatest minds. In the spirit of the multi-million-copy, #1 New York Times bestselling The Book of Questions, comes John Brockman's The Last Unknowns, the conclusion to the bestselling Edge Question Series.

Every great thinker has his or her "ultimate question," the unknown that, if answered, could unlock the secrets of our world, our civilization, and even the meaning of life. And so, John Brockman asked 284 of the world's leading scientists, academics, artists, and intellectuals, "What is 'The Last Question,' your last question, the question for which you will be remembered?"
