### Stephen Hawking Biography

**Stephen Hawking ( Stephen William Hawking ) CH CBE FRS FRSA (8 January 1942 – 14 March 2018) was an English theoretical physicist, cosmologist, and author who was the director of research at the Centre for**

Theoretical Cosmology at the University of Cambridge at the time of his death. He was the Lucasian Professor of Mathematics at the University of Cambridge between 1979 and 2009.

### Stephen Hawking Age

Hebn Died at the Age of **76**. Renowned British theoretical physicist and Cambridge Professor Stephen Hawking has “died peacefully at his home in Cambridge” at the age of **76**, according to a spokesperson for the Hawking family.

### Stephen Hawking Height

Details concerning his height are still under research and will soon be updated immediately we come across details concerning his height.

### Stephen Hawking Family

Stephen William Hawking was born on January 8, 1942, in Oxford, England. His father, a well-known researcher in tropical medicine, urged his son to seek a career in medicine, but Stephen found biology and medicine were not exact enough. Therefore, he turned to the study of mathematics and physics.

### Stephen Hawking Education

The onset of Hawking’s graduate education at Cambridge marked a turning point in his life. It was then that he embarked upon the formal study of cosmology, which focused his study. And it was then that he was first stricken with Lou Gehrig’s disease, a weakening disease of the nervous and muscular system that eventually led to his total confinement in a wheelchair. At Cambridge, his talents were recognized, and he was encouraged to carry on his studies despite his growing physical disabilities. His marriage in 1965 was an important step in his emotional life. Marriage gave him, he recalled, the determination to live and make professional progress in the world of science. Hawking received his doctorate degree in 1966. He then began his lifelong research and teaching association with Cambridge University.

### Stephen Hawking Career

In his work, and in collaboration with Penrose, Hawking extended the singularity theorem concepts first explored in his doctoral thesis. This included not only the existence of singularities but also the theory that the universe might have started as a singularity. Their joint essay was the runner-up in the 1968 Gravity Research Foundation competition. In 1970, they published a proof that if the universe obeys the general theory of relativity and fits any of the models of physical cosmology developed by Alexander Friedmann, then it must have begun as a singularity. In 1969, Hawking accepted a specially created Fellowship for Distinction in Science to remain at Caius.

In 1970, Hawking postulated what became known as the second law of black hole dynamics, that the event horizon of a black hole can never get smaller.[92] With James M. Bardeen and Brandon Carter, he proposed the four laws of black hole mechanics, drawing an analogy with thermodynamics. To Hawking’s irritation, Jacob Bekenstein, a graduate student of John Wheeler, went further—and ultimately correctly—to apply thermodynamic concepts literally.

In the early 1970s, Hawking’s work with Carter, Werner Israel, and David C. Robinson strongly supported Wheeler’s no-hair theorem, one that states that no matter what the original material from which a black hole is created, it can be completely described by the properties of mass, electrical charge and rotation. His essay titled “Black Holes” won the Gravity Research Foundation Award in January 1971. Hawking’s first book, The Large Scale Structure of Space-Time, written with George Ellis, was published in 1973.

Beginning in 1973, Hawking moved into the study of quantum gravity and quantum mechanics. His work in this area was spurred by a visit to Moscow and discussions with Yakov Borisovich Zel’dovich and Alexei Starobinsky, whose work showed that according to the uncertainty principle, rotating black holes emit particles. To Hawking’s annoyance, his much-checked calculations produced findings that contradicted his second law, which claimed black holes could never get smaller and supported Bekenstein’s reasoning about their entropy.

# Soon After Seeing The First Black Hole’s Picture, Physicists Prove Stephen Hawking’s Theory On ‘Black Hole Evaporation’

- After putting stupendous efforts to capture the first picture of a black hole, physicists have now shown that black holes eventually evaporate entirely
- The famous physicist Stephen Hawking had predicted the above theory in 1974 stating that black holes are not perfectly “black” but instead emit particles which Hawking believed could eventually siphon enough energy and mass away from black holes to make them disappear.
- After putting stupendous efforts to capture the first picture of a black hole, physicists have now shown that black holes eventually evaporate entirely, according to Live Science.The famous physicist Stephen Hawking had predicted the above theory in 1974 stating that black holes are not perfectly “black” but instead emit particles which Hawking believed could eventually siphon enough energy and mass away from black holes to make them disappear. While the theory was theoretically believed to be true by scientists, it was impossible to be proven.
