A new book completed posthumously by his family reveals Stephen Hawking’s thoughts on some of the most common questions he received during his life.
The physicist, who has suffered from ALS for most of his life, died earlier this year at the age of 76.
Among the assertions he included in his latest book is a reiteration of his atheism.
“There is no God,” he wrote. “No one directs the universe.”
In “Brief Answers to the Big Questions,” he went on to declare that there are “forms of intelligent life out there” beyond Earth and that traveling “back in time can’t be ruled out according to our present understanding.”
