Ahli Fisika dan Kosmologi Stephen Hawking Meninggal Dunia


The physicist and author of A Brief History of Time has died at his home in Cambridge. His children said: ‘We will miss him for ever’

Stephen Hawking, the brightest star in the firmament of science, whose insights shaped modern cosmology and inspired global audiences in the millions, has died aged 76.

His family released a statement in the early hours of Wednesday morning confirming his death at his home in Cambridge.

Hawking’s children, Lucy, Robert and Tim said in a statement: “We are deeply saddened that our beloved father passed away today.

“He was a great scientist and an extraordinary man whose work and legacy will live on for many years. His courage and persistence with his brilliance and humour inspired people across the world.

“He once said: ‘It would not be much of a universe if it wasn’t home to the people you love.’ We will miss him for ever.”

For fellow scientists and loved ones, it was Hawking’s intuition and wicked sense of humour that marked him out as much as the fierce intellect which, coupled with his illness, came to symbolise the unbounded possibilities of the human mind.

I’m not afraid of death, but I’m in no hurry to die. I have so much I want to do first Stephen Hawking

Hawking was driven to Wagner, but not the bottle, when he was diagnosed with motor neurone disease in 1963 at the age of 21. Doctors expected him to live for only two more years. But Hawking had a form of the disease that progressed more slowly than usual. He survived for more than half a century.

Hawking once estimated he worked only 1,000 hours during his three undergraduate years at Oxford. In his finals, he came borderline between a first and second class degree. Convinced that he was seen as a difficult student, he told his viva examiners that if they gave him a first he would move to Cambridge to pursue his PhD. Award a second and he threatened to stay. They opted for a first.

Those who live in the shadow of death are often those who live most. For Hawking, the early diagnosis of his terminal disease, and witnessing the death from leukaemia of a boy he knew in hospital, ignited a fresh sense of purpose. “Although there was a cloud hanging over my future, I found, to my surprise, that I was enjoying life in the present more than before. I began to make progress with my research,” he once said. Embarking on his career in earnest, he declared: “My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all.”

He began to use crutches in the 1960s, but long fought the use of a wheelchair. When he finally relented, he became notorious for his wild driving along the streets of Cambridge, not to mention the intentional running over of students’ toes and the occasional spin on the dance floor at college parties.

Hawking’s first major breakthrough came in 1970, when he and Roger Penrose applied the mathematics of black holes to the universe and showed that a singularity, a region of infinite curvature in spacetime, lay in our distant past: the point from which came the big bang.

Penrose found he was able to talk with Hawking even as the latter’s speech failed. Hawking, he said, had an absolute determination not to let anything get in his way. “He thought he didn’t have long to live, and he really wanted to get as much as he could done at that time.”

There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark Stephen Hawking

In 1974 Hawking drew on quantum theory to declare that black holes should emit heat and eventually pop out of existence. For normal-sized black holes, the process is extremely slow, but miniature black holes would release heat at a spectacular rate, eventually exploding with the energy of a million one-megaton hydrogen bombs.

His proposal that black holes radiate heat stirred up one of the most passionate debates in modern cosmology. Hawking argued that if a black hole could evaporate, all the information that fell inside over its lifetime would be lost forever. It contradicted one of the most basic laws of quantum mechanics, and plenty of physicists disagreed. Hawking came round to believing the more common, if no less baffling, explanation that information is stored at a black hole’s event horizon, and encoded back into radiation as the black hole radiates.

Marika Taylor, a former student of Hawking’s and now professor of theoretical physics at Southampton University, remembers how Hawking announced his U-turn on the information paradox to his students. He was discussing their work with them in the pub when Taylor noticed he was turning his speech synthesiser up to the max. “I’m coming out!” he bellowed. The whole pub turned around and looked at the group before Hawking turned the volume down and clarified the statement: “I’m coming out and admitting that maybe information loss doesn’t occur.” He had, Taylor said, “a wicked sense of humour.”

Hawking’s run of radical discoveries led to his election in 1974 to the Royal Society at the young age of 32. Five years later, he became the Lucasian professor of mathematics at Cambridge, arguably Britain’s most distinguished chair, and one formerly held by Isaac Newton, Charles Babbage and Paul Dirac, the latter one of the founding fathers of quantum mechanics.

Hawking’s seminal contributions continued through the 1980s. The theory of cosmic inflation holds that the fledgling universe went through a period of terrific expansion. In 1982, Hawking was among the first to show how quantum fluctuations – tiny variations in the distribution of matter – might give rise through inflation to the spread of galaxies in the universe. In these tiny ripples lay the seeds of stars, planets and life as we know it.

But it was A Brief History of Time that rocketed Hawking to stardom. Published for the first time in 1988, the title made the Guinness Book of Records after it stayed on the Sunday Times bestsellers list for an unprecedented 237 weeks. It sold 10m copies and was translated into 40 different languages. Nevertheless, wags called it the greatest unread book in history.

Hawking married his college sweetheart, Jane Wilde, in 1965, two years after his diagnosis. She first set eyes on him in 1962, lolloping down the street in St Albans, his face down, covered by an unruly mass of brown hair. A friend warned her she was marrying into “a mad, mad family”. With all the innocence of her 21 years, she trusted that Stephen would cherish her, she wrote in her 2013 book, Travelling to Infinity: My Life With Stephen.

In 1985, during a trip to Cern, Hawking was taken to hospital with an infection. He was so ill that doctors asked Jane if they should withdraw life support. She refused, and Hawking was flown back to Addenbrooke’s Hospital in Cambridge for a lifesaving tracheotomy. The operation saved his life but destroyed his voice. The couple had three children, but the marriage broke down in 1991. Hawking’s progressive condition, his demands on Jane, and his refusal to discuss his illness, were destructive forces the relationship could not endure, she said. Jane wrote of him being “a child possessed of a massive and fractious ego,” and how husband and wife became “master” and “slave”.

Four years later, Hawking married Elaine Mason, one of the nurses employed to give him round-the-clock care. The marriage lasted 11 years, during which Cambridgeshire police investigated a series of alleged assaults on Hawking. The physicist denied that Elaine was involved, and refused to cooperate with police, who dropped the investigation.

Hawking was not, perhaps, the greatest physicist of his time, but in cosmology he was a towering figure. There is no perfect proxy for scientific worth, but Hawking won the Albert Einstein Award, the Wolf Prize, the Copley Medal, and the Fundamental Physics Prize. The Nobel prize, however, eluded him.

My goal is simple. It is a complete understanding of the universe, why it is as it is and why it exists at all Stephen Hawking

He was fond of scientific wagers, despite a knack for losing them. In 1975, he bet the US physicist Kip Thorne a subscription to Penthouse that the cosmic x-ray source Cygnus X-1 was not a black hole. He lost in 1990. In 1997, Hawking and Thorne bet John Preskill an encyclopaedia that information must be lost in black holes. Hawking conceded in 2004. In 2012, Hawking lost $100 to Gordon Kane for betting that the Higgs boson would not be discovered.

He lectured at the White House during the Clinton administration – his oblique references to the Monica Lewinsky episode evidently lost on those who screened his speech – and returned in 2009 to receive the presidential medal of freedom from Barack Obama. His life was played out in biographies and documentaries, most recently The Theory of Everything, in which Eddie Redmayne played him. He appeared on The Simpsons and played poker with Einstein and Newton on Star Trek: The Next Generation. He delivered gorgeous put-downs on The Big Bang Theory. “What do Sheldon Cooper and a black hole have in common?” Hawking asked the fictional Caltech physicist whose IQ comfortably outstrips his social skills. After a pause, the answer came: “They both suck.”

Hawking has argued that for humanity to survive it must spread out into space, and has warned against the worst applications of artificial intelligence, including autonomous weapons.

Hawking was happy to court controversy and was accused of being sexist and misogynist. He turned up at Stringfellows lap dancing club in 2003, and years later declared women “a complete mystery”. In 2013, he boycotted a major conference in Israel on the advice of Palestinian academics.

Some of his most outspoken comments offended the religious. In his 2010 book, Grand Design, he declared that God was not needed to set the universe going, and in an interview with the Guardian a year later, dismissed the comforts of religious belief.

“I regard the brain as a computer which will stop working when its components fail. There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark,” he said.

He spoke also of death, an eventuality that sat on a more distant horizon than doctors thought. “I’m not afraid of death, but I’m in no hurry to die. I have so much I want to do first,” he said.

What astounded those around him was how much he did achieve. He leaves three children, Robert, Lucy and Timothy, from his first marriage to Jane Wilde, and three grandchildren.

World renowned physicist Stephen Hawking has died at the age of 76.

He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.

The Briton was known for his work with black holes and relativity, and wrote several popular science books including A Brief History of Time.

At the age of 22 Prof Hawking was given only a few years to live after being diagnosed with a rare form of motor neurone disease.

The illness left him in a wheelchair and largely unable to speak except through a voice synthesiser.

In a statement his children, Lucy, Robert and Tim, said: "We are deeply saddened that our beloved father passed away today.

"He was a great scientist and an extraordinary man whose work and legacy will live on for many years."

They praised his "courage and persistence" and said his "brilliance and humour" inspired people across the world.

"He once said, 'It would not be much of a universe if it wasn't home to the people you love.' We will miss him forever."

A book of condolence is due to be opened at Conville and Caius College in Cambridge, where Prof Hawking was a fellow.

Prof Hawking was the first to set out a theory of cosmology as a union of relativity and quantum mechanics.

He also discovered that black holes leak energy and fade to nothing - a phenomenon that would later become known as Hawking radiation.

Through his work with mathematician Sir Roger Penrose he demonstrated that Einstein's General Theory of Relativity implies space and time would have a beginning in the Big Bang and an end in black holes.

The scientist gained popularity outside the academic world and appeared in several TV shows including The Simpsons, Red Dwarf and The Big Bang Theory.

He was portrayed in both TV and film - recently by Oscar winner Eddie Redmayne in The Theory of Everything, which charted his rise to fame and relationship with his first wife, Jane.

Defence Minister Tobias Ellwood said Prof Hawking was "an inspiration to us all, whatever our station in life, to reach for the stars".

He tweeted: "RIP Sir. You epitomised true courage over adversity as you explained the wonders of the universe to the world. Your achievements symbolise the pwr (sic) of the human mind."

Local government minister Sajid Javid said: "One of most inspirational people throughout my life. A brief history on earth, an eternity in the stars."

Apple's co-founder Steve Wozniak said: "Stephen Hawking's integrity and scientific dedication placed him above pure brilliance,"

Satya Nadella, Microsoft chief executive, said: "We lost a great one today. Stephen Hawking will be remembered for his incredible contributions to science - making complex theories and concepts more accessible to the masses.

"He'll also be remembered for his spirit and unbounded pursuit to gain a complete understanding of the universe, despite the obstacles he faced."

In his 2013 memoir he described how he felt when first diagnosed with motor neurone disease.

"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."

Speaking to the BBC in 2002, his mother, Isobelle, described him as a "very normal young man".

She said: "He liked parties. He liked pretty girls - only pretty ones. He liked adventure and he did, to some extent, like work."
