What was the name of the posthumous book by Stephen Hawking published in 2018?

Stephen Hawking’s posthumous book published in 2018 was Brief Answers to the Big Questions. It was released after his death and presented his final reflections on major questions about science, humanity, and the future.

The book was published in October 2018 and drew together material from essays, lectures, interviews, and answers Hawking had developed during his career. Its subjects include black holes, the origins of the universe, time travel, artificial intelligence, extraterrestrial life, and humanity’s long-term survival.

It is often confused with A Brief History of Time, Hawking’s 1988 bestseller, or with My Brief History, his autobiographical account. Brief Answers to the Big Questions is different: it is a collection of concise responses to broad intellectual and practical questions rather than a continuous history of cosmology or Hawking’s life.

The published edition included a foreword by actor Eddie Redmayne, an introduction by physicist Kip Thorne, and an afterword by Hawking’s daughter Lucy.
