"There is no God," says Stephen Hawking in the latest book

There is no God – this is the conclusion of the famous physicist Stephen Hawking, whose latest book was published Tuesday.

The book, which was completed by his family after his death, provides answers to questions that Hawking said he received most often during his stay on Earth.

The British scientist told his readers the belief that extraterrestrial life exists, that artificial intelligence could outmaneuver humans and that travel over time is not excluded.

Hawking, considered one of the brightest scientists of his generation, died in March at the age of 76.

"There is no God, no one directs the universe," he writes in "Brief Answers to Big Questions."

"For centuries, it was believed that people with disabilities like me lived under a curse inflicted by God," he adds. "I prefer to think that everything can be explained in another way, by the laws of nature."

Hawking has suffered from Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease also known as Lou Gehrig's disease, for most of his adult life.

The scientist died while he was still working on the book, which his family and colleagues finished with the help of his extensive personal archives.

"Looking more and more in the interior"

If Hawking spoke of his lack of belief in God during his life, many of his other answers are more surprising.

"There are intelligent life forms out there," he writes. "We must be careful not to answer until we have developed a little further."

And it leaves open the possibility of other phenomena.

"A trip back in time can not be ruled out according to our current understanding," he says. He also predicts that "a hundred years from now, we will be able to travel anywhere in the solar system".

"He realized that people just wanted him to answer those questions," Lucy Hawking, the scientist's daughter, told CNN, who helped produce the book.

Hawking saw the world on the brink of a "profound change in depth" when he died, she said, adding, "He is asking us not to go blindly into the future. What is the quality of the experience of the human race in the use of technological advances for the sake of ordinary people? "

In an address prepared by Hawking and aired Monday in London, the scientist also turned to the world that he was leaving.

"With Brexit and Trump exerting new strengths in immigration and educational development, we are witnessing a worldwide revolt against the experts, and that includes scientists," said Hawking.

Hawking had criticized the UK's decision to leave the EU and called Donald Trump a "demagogue" in 2016.

His biggest concern, said his daughter, "is the division we are in," adding, "He comments on how much we seem to have lost the ability to look outward and we are turning more and more towards ourselves."

Hawking's latest message to readers, however, is hopeful.

Attempting to answer the question "How are we shaping the future?", In the last chapter of the book, the scientist writes: "Do not forget to look at the stars and not at your feet. "
