Stephen Hawking's latest work, which addresses issues ranging from the existence of God to the potential of time travel, was launched Monday by his children, who helped to finish the book after the death of the British giant's l & # 39; astrophysics.
Hawking was always asked the same things and he started working on "Brief Answers to Big Questions" last year – but did not finish it until his death in March at age 76 years old.
It was completed by the family of the theoretical physicist and his academic colleagues, with material drawn from his extensive personal archives.
"He was regularly asked a series of questions," said his daughter Lucy Hawking at the Science Museum in London.
The book was an attempt to "bring together the most definitive, clearest, and most authentic answers he has given.
"We all wish that he be here to see him."
Hawking, who was in a wheelchair due to a motor neuron disease, has devoted the work of his life to solving the mysteries of the universe.
The cosmologist was propelled to fame by his 1988 book "A Brief History of Time," an unlikely world bestseller.
He conquered fans far beyond the rarefied world of astrophysics and prompted people to ask his brain for his opinion on larger topics, responded in his final work.
– The big questions –
The 10 questions raised by Hawking are:
– Is there a God?
– How it all began?
– What's inside a black hole?
– Can we predict the future?
– Is the journey in time possible?
– Are we going to survive on Earth?
– Is there another intelligent life in the universe?
– Should we colonize space?
– Is artificial intelligence going to beat us?
– How are we shaping the future?
– Multiple challenges –
In his book, Hawking says that humans have no choice but to leave Earth, risking being "annihilated" if they do not.
He says computers will surpass humans in intelligence over the next 100 years, but "we will have to make sure that the goals of these computers are aligned with ours."
Hawking said that the human race must improve its mental and physical qualities, but that a genetically modified superhuman race, with greater memory and resistance to disease, would endanger others.
He says that when people understand what is happening with climate change, it may be too late.
Hawking says that the simplest explanation is that God does not exist and that there is no reliable evidence of a life after death, although people can survive thanks to their influence and their genes.
He says that in the next 50 years, we will understand how life began and perhaps we will find out if life exists elsewhere in the universe.
"He was deeply concerned that at a time when the challenges were global, our thinking was becoming more and more local," said Lucy Hawking.
"It's a call to unity, to humanity, to pull ourselves together and face the challenges ahead."
In his latest academic article, Hawking shed new light on black holes and the paradox of information, with new work calculating the entropy of black holes.
Transformed into an animation told by the artificial voice of Hawking, it was shown at the launch of the book.
"It was very emotional, I turned away from me because I had tears of tears," said Hawking Lucy to AFP on hearing her father's voice.
"We sometimes feel that he's still here because we're talking about him and hearing his voice – and then we have the reminder that he has left us."
Stephen Hawking's latest book addresses issues ranging from the existence of God to the potential of traveling back in time.
Lucy, the daughter of Hawking, said that a series of questions was regularly asked to the scientist and that the book was trying to answer them in the clearest possible way.
