Stephen Hawking, who sought to explain some of the most complicated questions of life while himself working under the shadow of a likely premature death, has died at 76.

He died peacefully at his home in the British university city of Cambridge in the early hours of Wednesday.

“We are deeply saddened that our beloved father passed away today,” his children Lucy, Robert and Tim said in a statement.

Hawking’s formidable mind probed the very limits of human understanding both in the vastness of space and in the bizarre sub-molecular world of quantum theory, which he said could predict what happens at the beginning and end of time.

His work ranged from the origins of the universe itself, through the tantalizing prospect of time travel to the mysteries of space’s all-consuming black holes.

“He was a great scientist and an extraordinary man whose work and legacy will live on for many years,” his family said.

“His courage and persistence with his brilliance and humor inspired people across the world.”

The power of his intellect contrasted cruelly with the weakness of his body, ravaged by the wasting motor neurone disease he contracted at the age of 21.

Hawking was confined for most of his life to a wheelchair.

As his condition worsened, he had to resort to speaking through a voice synthesizer and communicating by moving his eyebrows.

The disease spurred him to work harder but also contributed to the collapse of his two marriages, he wrote in a 2013 memoir “My Brief History.”

In the book he related how he was first diagnosed: “I felt it was very unfair – why should this happen to me,” he wrote.

“At the time, I thought my life was over and that I would never realise the potential I felt I had. But now, 50 years later, I can be quietly satisfied with my life.”

Hawking shot to international fame after the 1988 publication of ““A Brief History of Time”, one of the most complex books ever to achieve mass appeal, which stayed on the Sunday Times best-sellers list for no fewer than 237 weeks.

He said he wrote the book to convey his own excitement over recent discoveries about the universe.

“”My original aim was to write a book that would sell on airport bookstalls,” he told reporters at the time. ““In order to make sure it was understandable I tried the book out on my nurses. I think they understood most of it.”

He was particularly proud that the book contains only one mathematical equation – relativity’s famous E=MC squared.

His popular recognition became such that he appeared as himself on the television show “Star Trek: Next Generation” and his cartoon caricature appeared on “The Simpsons”.

A 2014 film, The Theory of Everything, with Eddie Redmayne playing Hawking, charted the onset of his illness and his early life as the brilliant student grappling with black holes and the concept of time.

Since 1974 he worked extensively on marrying the two cornerstones of modern physics – Einstein’s General Theory of Relativity, which concerns gravity and large-scale phenomena, and quantum theory, which covers subatomic particles.

As a result of that research, Hawking proposed a model of the universe based on two concepts of time: “”real time”, or time as human beings experience it, and “quantum theory’s “imaginary time”, on which the world may really run.

“Imaginary time may sound like science fiction … but it is a genuine scientific concept,” he wrote in a lecture paper.

Real time could be perceived as a horizontal line, he said.

In July 2002, Hawking said in a lecture that although his quest was to explain everything, a theory of determinism that would predict the universe in the past and forever in the future probably could not be achieved.

He caused some controversy among biologists when he said he saw computer viruses as a life form, and thus the human race’s first act of creation.

“”I think it says something about human nature that the only form of life we have created so far is purely destructive,” he told a computer forum in Boston. ““We’ve created life in our own image.”

He also predicted the development of a “race of self-designing human beings, who will use genetic engineering to improve their make-up.

Another major area of his research was into black holes, the regions of space-time where gravity is so strong that nothing, not even light, can escape.

When asked whether God had a place in his work, Hawking once said: ““In a way, if we understand the universe, we are in the position of God.”

His health, and accidents involving his wheelchair, including one where he broke his hip after crashing into a wall in December 2001 – “the wall won,” he observed – led to his appearing in the news for reasons other than his work.

In 2004 he was admitted to hospital in Cambridge suffering from pneumonia and was later transferred to a specialist heart and lung hospital.

He was twice married and divorced. (Reuters/NAN)
