THEORETICAL PHYSICIST STEPHEN HAWKING DIES
Stunned doctors by living more than 50 years with ALS
LONDON — Stephen Hawking, whose brilliant mind ranged across time and space though his body was paralyzed by disease, has died, a family spokesman said early Wednesday.
The best- known theoretical physicist of his time, Mr. Hawking wrote so lucidly of the mysteries of space, time and black holes that his book, “A Brief History of Time,” became an international best- seller, making him one of science’s biggest celebrities since Albert Einstein.
“He was a great scientist and an extraordinary man whose work and legacy will live on for many years,” his children Lucy, Robert and Tim said in a statement. “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 forever.”
Even though his body was attacked by amyotrophic lateral sclerosis, or ALS, when Mr. Hawking was 21, he stunned doctors by living with the normally fatal illness for more than 50 years. A severe attack of pneumonia in 1985 left him breathing through a tube, forcing him to communicate through an electronic voice synthesizer that gave him his distinctive robotic monotone.
But he continued his scientific work, appeared on television and married for a second time.
As one of Isaac Newton’s successors as Lucasian Professor of Mathematics at Cambridge University, Mr. Hawking was involved in the search for the great goal of physics— a “unified theory.”
Such a theory would resolve the contradictions between Einstein’s General Theory of Relativity, which describes the laws of gravity that govern the motion of large objects like planets, and the Theory of Quantum Mechanics, which deals with the world of subatomic particles.
For Mr. Hawking, the search was almost a religious quest — he said finding a “theory of everything” would allow mankind to “know the mind of God.”
“A complete, consistent unified theory is only the first step: our goal is a complete understanding of the events around us, and of our own existence,” he wrote in “A Brief History of Time.”
In later years, though, he suggested a unified theory might not exist.
He followed up “A Brief History of Time” in 2001 with the more accessible sequel “The Universe in a Nutshell,” updating readers on concepts like super gravity, naked singularities and the possibility of an 11- dimensional universe.
Mr. Hawking said belief in a God who intervenes in the universe “to make sure the good guys win or get rewarded in the next life” was wishful thinking.
“But one can’t help asking the question: Why does the universe exist?” he said in 1991. “I don’t know an operational way to give the question or the answer, if there is one, a meaning. But it bothers me.”
He made cameo television appearances in “The Simpsons” and “Star Trek” and counted among his fans U2 guitarist The Edge, who attended a January 2002 celebration of Mr. Hawking’s 60th birthday.
His early life was chronicled in the 2014 film “The Theory of Everything,” with Eddie Redmayne winning the best actor Academy Award for his portrayal of the scientist. The film focused still more attention on Mr. Hawking’s remarkable achievements.
Richard Green, of the Motor Neurone Disease Association— the British name for ALS — said Mr. Hawking met the classic definition of the disease, as “the perfect mind trapped in an imperfect body.”
He said Mr. Hawking had been an inspiration to people with the disease for many years.
Mr. Hawking first earned prominence for his theoretical work on black holes. Disproving the belief that black holes are so dense that nothing could escape their gravitational pull, he showed that black holes leak a tiny bit of light and other types of radiation, now known as “Hawking radiation.”
“It came as a complete surprise,” said Gary Horowitz, a theoretical physicist at the University of California, Santa Barbara. “It really was quite revolutionary.”
Mr. Hawking’s other major scientific contribution was to cosmology, the study of the universe’s origin and evolution. Working with Jim Hartle of the University of California, Santa Barbara, Mr. Hawking proposed in 1983 that space and time might have no beginning and no end. “Asking what happens before the Big Bang is like asking for a point onemile north of the North Pole,” he said.
Mr. Hawking was born Jan. 8, 1942, in Oxford, and grewup in London and St. Albans. In 1959, he entered Oxford University and then went on to graduate work at Cambridge.
Signs of illness appeared in his first year of graduate school, and he was diagnosed with ALS, also known as Lou Gehrig’s disease after the New York Yankee star who died of it. The disease usually kills within three to five years.
According to John Boslough, author of “Stephen Hawking’s Universe,” Mr. Hawking became deeply depressed. But as it became apparent that he was not going to die soon, his spirits recovered and he bore down on his work. Brian Dickie, director of research at the Motor Neurone Disease Association, said only 5 percent of those diagnosed with ALS survive for 10 years or longer. Mr. Hawking, he added, “really is at the extreme end of the scale when it comes to survival.”
Mr. Hawking married Jane Wilde in 1965 and they had three children, Robert, Lucy and Timothy.
Jane cared for Hawking for 20 years, until a grant from the United States paid for the 24- hour care he required.
Mr. Hawking divorced Jane in 1991, an acrimonious split that strained his relationship with their children. Mr. Hawking married his one- time nurse Elaine Mason four years later, but the relationship was dogged by rumors of abuse.
Police investigated in 2004 after newspapers reported that he’d been beaten, suffering injuries including a broken wrist, gashes to the face and a cut lip, and was left stranded in his garden on the hottest day of the year.
Mr. Hawking called the charges “completely false.” Police found no evidence of any abuse. Hawking and Mason separated in 2006.
